▼ Over 10,000 monogenic diseases in the world affect one out of every hundred live births (WHO). Gene targeting is a term that is used describe the manipulation of genetic material, either by adding a gene in a specific locus, creating a mutation at a specific locus, or correcting a gene at a specific locus. Here, unless otherwise noted, we will use the term to describe the correction of a gene with a homologous piece of donor genetic material whereby a mutant gene that causes monogenic disease is essentially replaced by a wild type copy through homologous recombination. Thus, gene targeting is inherently safer than classic gene therapy, where a gene is randomly introduced into the genome and can cause insertional mutagenesis. Although the rates of homologous recombination are low when simply delivering a donor substrate (1 in a million), creating a deoxyribonucleic acid (DNA) double-stranded break in or around the gene of interest using a nuclease, increases the rate of gene targeting 30,000-50,000 fold. The delivery of the nuclease and donor substrate to these cells is one of the major hurdles in achieving this type of therapy. However, for classic gene therapy there have already been many clinical trials using viral vehicles for gene delivery. One problem with using a virus for gene therapy is the low titer associated with some types of virus, in particular,
lentivirus. In the first part of this dissertation, this problem is addressed by showing that the addition of caffeine during viral production can increase titer up to 8-fold.
Besides
lentivirus, other viruses, like Adeno-associated virus (AAV) have been used in clinical trials. There are nine AAV serotypes, but the most-well characterized is AAV2. Because there are situations where AAV is to be used in cells that cannot be transduced with AAV2, it is essential to know which serotype best infects the desired cell type. The second part of the dissertation describes a comprehensive survey of the ability of AAV1-9 and one engineered serotype to transduce primary and immortalized cells from human, mouse, hamster, and monkey origin. Overall, the results show that AAV1 and AAV6 transduce the most cell types at the highest efficiencies.
Though gene targeting has been achieved using the homing endonuclease I-Sce in AAV2, targeting has never been achieved using two zinc-finger nucleases (ZFNs) in any AAV serotype. This is significant because the recognition site for I-Sce is not found in the human genome, while ZFNs are designed to specifically bind in or around a gene of interest. Based on the results from the AAV survey and the advantage of ZFNs, we created an AAV6 virus that carried the genetic information for both ZFNs and donor substrate for gene targeting in cells containing a GFP gene targeting system. We also created an AAV6 virus that carried the donor substrate alone. The third part of this dissertation reveals that dual infection at the optimal multiplicities of infection for both AAV viruses can achieve targeting efficiencies of ~3%, which is…

▼ Gene therapy potentially holds the key for the treatment and cure of many genetic diseases, including cystic fibrosis. A number of delivery methods have been developed for the integration of a functional gene into the host genome, one of which is the use of a HIV-1 derived
lentivirus, as is used in this thesis. However, a large number of issues need to be addressed before an effective gene therapy protocol can be developed, and some of these are described further in this thesis.
One such issue is that the response initiated by cells to the gene transfer vector need to be addressed, as organelles such as the proteasome and lysosome that break down foreign peptides and proteins may be involved in the degradation of our gene transfer vector, ultimately limiting the amount of gene transfer vector that is able to successfully integrate into the genome. Therefore, the potential use of proteasome and lysosome inhibitors for facilitating higher levels of gene transduction in vivo was investigated.
As this project uses a HIV-1 derived
lentivirus for gene transfer, the use of an inhibitor of the IN1/PML innate antiretroviral response (Leptomycin B) was also assessed, again with the aim of increasing the efficiency, and hence level, of gene transfer obtained.
Using a robust animal model of disease is essential for testing
lentivirus constructs containing the therapeutic gene and analysing phenotypic changes in disease. A mouse model of cystic fibrosis without gastrointestinal disease was bred to obtain a robust colony of mice that efficiently produce affected mice (CFTR knockout).
Visual analysis of therapeutic gene transfer in cystic fibrosis is often difficult due to the lack of antibodies available. Short DNA molecules that adopt a specific 3-D shape known as aptamers hold much potential as agents that can be developed to bind to the CFTR gene product. These can then be labelled and used in the same way as antibodies to probe tissues excised from animals treated with the therapeutic CFTR gene.
Essential to gene therapy is the development of methods for the consistent determination of
lentivirus titre. As the production of
lentivirus becomes more sophisticated with the use of multiple transgenes in a single virus preparation, the need for multiple assays to determine the titres of each individual virus component are required. Real time PCR assays were developed for each individual transgene for titre determination. A real time PCR assay for use with CHOK-1 cells was also developed for
comparison of real time PCR titre of a LacZ virus to the titre obtained using the traditional LacZ titre achieved via a staining assay in CHOK-1 cells. The use of a standard real time PCR assay for the determination of titre for all viruses- containing any transgene is essential to allow comparison by titre.
Determination of the level of gene expression required to achieve a therapeutic outcome in a cystic fibrosis mouse model is an important factor to consider, as high level expression in all cells may not achieve the best outcomes, and low…

▼ Developing transgenic livestock has become popular in recent years after advances in the field of genetic editing. Cattle are one of the main exports in New Zealand and are a prime target for new genetic editing tools. Applications of genetic editing in cattle can extend to increases in production, and elimination of disease genes. Due to its ease of use, CRISPR/Cas9 has become one of the most popular methods of editing genes, hence this was employed in the research. Cattle embryos in culture are very sensitive to environmental changes and for this reason, a delivery vector is necessary to deliver the genetic material as traditional transfection methods cause high rates of embryo death. The zona pellucida, a glycoprotein coat surrounding the embryo, acts as a protective agent against viral vectors, and needed to be considered in the research. This research aimed to create a novel, high titer
lentivirus particle capable of transducing bovine embryos, and causing subsequent genetic modification by integration of CRISPR/Cas9 into the genome. Using fluorescent reporters, viral transduction was monitored. The research found that after optimizing transfection protocols, high-titer lentiviral particles can be produced and can infect bovine embryos. Zona pellucida removal experiments revealed over-digestion in early stage embryos, however, this was not observed in compact morulas. Removing the zona allowed for successful transduction of bovine embryos, resulting in transgenic cells expressing eGFP. While CRISPR/Cas9 experiments were in preliminary stages, these indicated eGFP knock-out in certain eGFP-HEK293T cells. Though challenges were encountered throughout the research process, solutions were explored, and it was shown that transgenic bovine embryos using lentiviral gene delivery can be produced. This indicates the high likelihood that CRISPR/Cas9 systems can be delivered this way, inducing targeted genetic modification.

▼ In recent times, cattle embryology has been under the spotlight of investigation due to its apparent economic values. This is especially relevant in the case of New Zealand, owing to its high percentage of livestock export. Specifically, the period of peri-implantation development has been of particular relevance. During this stage, the developing zygote will establish 3 key lineages – epiblast, hypoblast and trophoblast. Previous studies have elucidated that a significant number of embryos die prior to implantation, therefore highlighting the importance of correctly establishing these 3 lineages to overall embryonic survival.
However, while embryological stages of the preimplantation embryo have been extensively studied in their eutherian cousin, mice, the molecular regulation of that of cattle remains much less addressed. Whereas the regulation of bovine embryo development is orchestrated by many transcriptional regulators, or genetic regulatory networks (GNP), we aimed to focus our studies on 2 key transcriptional regulators, GATA4 and GATA6. During early embryogenesis, both these transcriptional factors are known molecular regulators that drive the establishment of the hypoblast lineage in mice. By and large, while their respective expression has been documented in cattle embryos, functional studies towards these markers have not yet been performed.
Latest advances in molecular biology have given us novel methods to study the mechanism of bovine embryogenesis. To this end, the continuing perfection of CRISPR technologies in the last decade - in particular its delivery through lentiviral vectors, has established an ability to generate stable, targeted knock-out mutants. Therefore, it is aimed in this thesis to design and test lentiviral particles that induce knock-out mutants of GATA4 and GATAT6, to test their efficacy in primary cell cultures (bovine cumulus cells) and to functionally analyse the effect of GATA4 and GATA6 knockdowns in early bovine embryos.

▼ The development of lentiviral vectors to deliver genes
to specific cell types are useful tools because they have the
ability to produce stable transduction, maintain long-term
transgene expression, and transduce both dividing and non-dividing
cells. Despite the high transduction efficiency of lentiviral
vectors, their tropism frequently does not match the desired gene
delivery application. We report herein, strategies to modify
lentiviral vectors using diverse techniques which allow targeting
gene delivery to specific cell types. To target CD117 expressing
cells we engineered a lentivector that incorporates membrane-bound
human stem cell factor (hSCF), and for fusion, a Sindbis
virus-derived fusogenic molecule (FM) onto the lentiviral surface.
Lentiviral vectors pseudotyped with envelope proteins of
alphaviruses have recently attracted considerable interest for
their potential utilization for immunotherapy due to their capacity
to transduce dendritic cells. We report lentiviral vectors
pseudotyped with envelope glycoproteins derived from the Aura,
Sindbis and Semliki Forest alphaviruses have a natural capacity to
transduce dendritic cells through the DC-SIGN receptor. Finally, in
this study, we explore the ability of pseudotyped lentiviral
vectors with envelope glycoproteins derived from a neuroadapted
Sindbis virus envelope glycoprotein to specifically transduce
neuronal cell types. The development of engineered lentiviral
vectors to achieve targeted transduction while avoiding
transduction of non-target cells will be important tools for future
gene delivery implementation in a wide range of
fields.

▼ Many forms of leukaemia are caused by chromosomal translocations, which
result in specific and characteristic genomic sequences. Where these sequences are
unique to the leukaemic cells, they represent good candidates for targeting by sequencespecific
techniques, such as RNA-Interference (RNAi). RNAi is a mechanism inherent
in eukaryotic cells which silences target mRNAs based on homology to a dsRNA
template. This template may be introduced artificially by a number of methods, and so
this mechanism can be manipulated to regulate the expression of target genes. One of
the most efficient methods of introducing RNAi templates is by expression of shorthairpin
RNA (shRNA) cassettes from DNA plasmids or vectors.
Lentiviral vectors are based on viruses that integrate into the DNA of the host
cell, and are a highly efficient class of vectors for transducing and providing stable
transgene expression in a range of cell types. They are particularly effective at
tansducing haematopoietic cells, which have proven difficult to transduce by other
methods. By fine-tuning the methods of vector production and transduction, a range of
human leukaemic cells lines were able to be transduced with unprecedented efficiency
in the present study. Lentiviral transduction was combined with rapid puromycin
selection to generate a pure population of transduced cells with minimal expansion of
the cell population.
The strategy of expressing shRNAs from retroviral and lentiviral vectors
combined with puromycin selection was used to target three well-characterised fusion
genes; Bcr-Abl, PML/RARα and RUNX1/ETO, in three human leukaemic cell lines. In
two of these, the shRNA was able to efficiently and effectively down-regulate the target
mRNA, and inhibit the proliferation of the transduced leukaemic cells. In the third case,
RUNX1/ETO, no effective shRNA design could be identified.
Finally, concerns over the safety of integration targeting by current gene therapy
vectors motivated an investigation of the activity of a novel integrase enzyme from the
Ty3 retrotransposon found in yeast. In yeast cells, the integration-mediating enzyme of
this retrotransposon has very specific targeting characteristcs, which, if retained in
human cells, would provide a very safe gene therapy vector. It was found that this
enzyme is indeed active in human cells, and therefore has potential in the context of
human gene therapy.

▼ Feline immunodeficiency virus is an important lentiviral infection in cats. Infection is life-long and results in immune compromise, increased susceptibility to opportunistic infections and early mortality. Infection is commonly referred to in three stages: acute, (asymptomatic) and end stage (symptomatic); although not all cats will progress to end stage disease. Acute infection lasts several months during which cats may have mild, transient anorexia, lethargy, fever, lymphadenomegaly and diarrhea. There is loss of mucosal and peripheral CD4 T cells, expansion of a subset of CD8 T cells, CD8βlow, and establishment of viremia during this period. Asymptomatic infection lasts a variable period of years during which progressive decreases in CD4 T cells and inversion of the CD4:CD8 ratio occurs. End stage infection does not occur in all infected cats. It is characterized by a rapid decline in health including generalized muscle wasting, treatment-refractory opportunistic infection and / or neoplasia leading to death within months. A marked decrease in CD4 T cell counts and CD4:CD8 ratio and several fold increase in viremia occurs during end stage disease but reported literature is sparse. Longitudinal studies of specific pathogen free cats experimentally infected with FIV infection have focused primarily on acute and early asymptomatic stages of infection. Little has been reported on the transition from late chronic to end stage disease. Longitudinal studies of cats naturally infected with FIV are needed to better characterize the course of infection.

The cystic fibrosis airway gene therapy group (CFARG) based in Adelaide, Australia have developed a HIV-1 based LV vector that demonstrated expression of the corrective CFTR gene up to 12 months in the airways of CF mice. Using their two-step airway conditioning and bolus gene vector delivery technique, the CFARG have shown effective transduction in the airways of animal models such as sheep and marmosets. As this vector approaches clinical realisation there is a need to translate the bolus delivery regimen of this vector to an aerosol form. Aerosolisation would enable non-invasive and easily repeatable vector delivery, which could be used in future clinical trials. This thesis examines the efficiency of different delivery devices for aerosolising the LV vector. Cell culture studies showed that LV vector aerosolised using a newly developed ultrasonic surface acoustic wave (SAW) nebuliser produced significantly lower levels of gene expression than bolus delivery. This led to examination of an intra-tracheal sprayer, the MADgic™ atomisation device, which demonstrated promising results on delivering the vector as a spray, in cell culture studies. However, use of this device in human clinical studies is invasive. Therefore, the efficacy of delivering LV vector as an aerosol through other nebulisers was investigated. A baseline in vivo study was designed to aerosolise the LV vector into the lungs of mechanically ventilated mice using an Aeroneb®Pro vibrating mesh nebuliser with a flexiVent™ small animal ventilator. This was the first study to compare the levels of gene expression produced by a HIV-based LV vector delivered either as an aerosol or as a bolus dose into mouse lungs. Lower levels of gene expression were obtained in the trachea of aerosol-treated animals compared to bolus-treated animals. However, the effect of LV aerosol delivery could not be determined in other conducting airways or the lung parenchyma, due to low power of the study produced by a substantial outlier producing a far larger than expected variability. The reason for the lowered gene expression observed in the trachea of mice treated with LV vector delivered as an aerosol through the Aeroneb®Pro-flexiVent™ ventilator apparatus was not conclusive. Further experiments investigated the cause of the low levels of gene expression observed in the baseline in vivo study. Bench studies with dye solution revealed that the physical dose volume that reached the tip of the endotracheal (ET) tube following delivery through the ventilator circuit was only 2% of the initial dose volume, which likely explained the low levels of gene expression in trachea of aerosol-treated animals. The delivery parameters were therefore optimised to increase the aerosol output available at the end of the delivery circuit. Subsequent cell culture studies examined the gene expression produced by the LV vector aerosolised with parameters used in the baseline in vivo study. The results…

▼ Intrauterine growth restriction (IUGR) results in significant fetal and neonatal mortalities and morbidities. Additionally, infants surviving IUGR experience increased incidence of heart disease, diabetes, hypertension and stroke during adulthood. A major placental secretory product, placental lactogen (PL), is found at high levels in maternal and fetal circulation, and is significantly reduced in both human and sheep IUGR pregnancies. While the exact function of PL has not been defined for any species, it is thought to modulate the mobilization of maternal nutrients to the fetus. Recently, the development of lentiviral-mediated expression of short hairpin RNA (shRNA) within sheep conceptuses has provided a means of examining placental gene function in sheep. The objective of this research was to generate ovine PL (oPL) deficient sheep pregnancies using
lentivirus targeting the degradation of oPL mRNA, in order to assess the function of PL during pregnancy. We hypothesize that oPL deficiency during pregnancy will lead to IUGR near term. To test our hypothesis a preliminary study was conducted to evaluate the in vivo efficacy of lentiviral-oPL targeting vectors in the sheep placenta at 55 days gestational age (dGA). Efficiency of oPLmRNA degradation was first measured in vitro using twelve promoter-targeting sequence combinations, tested in three cell lines overexpressing oPL. Two oPL target sequences (tg2 and tg6) were used, as either shRNA or shRNAmiR (microRNA mimic) sequences. Subsequently, three lentiviral constructs; hLL3.7 tg6 (human U6 promoter expressing oPL tg6 shRNA), hEF-1 tg2 (human elongation factor-1α promoter expressing oPL tg 2 shRNAmiR) and oPGK tg6 (ovine phosphoglycerate kinase-1 promoter expressing oPL tg 6 shRNAmiR), were selected to be tested in vivo. Day 9 blastocysts were harvested from naturally mated donor ewes, infected with one of the lentiviral constructs, and 2 to 3 blastocysts were surgically transferred to recipient ewes. At 55 dGA, uterine vein (UtV) blood and placental tissues were collected for analysis of oPL expression, and compared to naturally mated controls (NMC). Based on a 95% confidence interval created from UtV oPL concentrations in NMC pregnancies (n=4), 3 out of 4 hLL3.7 tg6 pregnancies, 3 out of 4 hEF tg2 pregnancies and 4 out of 4 oPGK tg6 pregnancies were classified as responder pregnancies. Compared to NMC pregnancies, UtV oPL concentrations were significantly reduced (P≤0.05) in responder pregnancies. While we hypothesized that oPL deficiency will result in IUGR near-term, at 55 dGA there were no differences in fetal weights. To test our overall hypothesis, we generated 8 hEF-1-SC (human elongation factor-1α promoter expressing scrambled control shRNAmiR), 9 hEF-1 tg2, 7 hEF-1 tg6 (human elongation factor-1α promoter expressing oPL tg6 shRNAmiR) and 9 hLL3.7 tg6 singleton pregnancies that were harvested at 135 dGA. Based on two standard deviations below the mean placental weight of the hEF-1 SC pregnancies, 2 out of 7 hEF-1 tg6 pregnancies and 6 out…

▼ Osteoarthritis (OA) is a degenerative joint disease estimated to affect 630 million people worldwide. OA is characterized by the progressive loss of articular cartilage, damage to subchondral bone and chronic inflammation; unfortunately, there is no cure for OA. Human mesenchymal stem cells/multipotent stromal cells (MSCs) have been evaluated as a potential treatment, as these cells can contribute through differentiation into bone and cartilage, and act as trophic mediators to reduce inflammation and promote healing. The safety of MSC therapies has been widely demonstrated and currently, at least 13 clinical trials are testing the efficacy of MSCs to treat OA.
We hypothesized here that the efficacy of MSC therapy can be enhanced using lentiviral vectors to overexpress key factors including interleukin-10 (IL-10), IL-1 receptor antagonist (IL- 1RA) or fibroblast growth factor-2 (FGF-2). Based on our experience on how to perform these modifications in a clinically-compliant manner, our primary goal was to functionally characterize these genetically modified MSC in vitro. Collectively, experiments performed in our lab: (1) show effective over-expression of the respective transgenes at the mRNA and protein levels; (2) address the number of viral insertions per cell; (3) demonstrate that over-expressing FGF-2 exhibit increased proliferation rates and reduced differentiation potential into both the osteogenic and adipogenic lineage. In contrast, over-expression of IL-1RA or IL-10 did not affect cell proliferation or differentiation potential. Importantly, MSCs over-expressing IL-10 reveal significant immune suppressive abilities in vitro, as proliferation of PHA-activated peripheral blood mononuclear cells (PBMCs) were strongly inhibited in a co-culture system.
These results support the notion of a ???second generation of MSCs,??? using genetic modifications to enhance therapeutic efficacy, while maintaining an excellent safety profile. Treatment of naturally occurring OA in dogs is now underway using canine MSCs overexpressing homologous IL-10. These studies will help establish safety and generate a proof of concept for advancing to human trials.

▼ Adipocytes function as the major storage site for triacylglyerol (TAG) and have important roles as active endocrine cells. It is widely assumed that the endocrine function of fat cells is determined by their size. As adipocytes increase in size, they tend to release more pro-inflammatory secretions leading to the recruitment of macrophages, setting up a vicious cycle of inflammation. The aim of this study was to genetically manipulate the size of fat cells in culture to determine the effect on inflammatory behaviour. The size of adipocytes may be manipulated in vitro by increasing TAG storage in 3T3-L1 cells. Acyl-coenzyme A:diacylglycerol acyltransferase 1 (DGAT1) catalyses the final and only committed step of TAG synthesis. Therefore key strategies in this study were to achieve overexpression of DGAT1 in 3T3-L1 preadipocytes, assess the resulting phenotype following differentiation, and to examine the adipocyte response to inflammatory stimuli as well as interaction with RAW 264.7 macrophages. Interactions between the cells were simulated by incubating the 3T3- L1 adipocytes with secretions collected from RAW 264.7 macrophages and vice versa. DGAT1 was overexpressed in 3T3-L1 preadipocytes via recombinant lentivirus and resulted in a more than 16-fold increase in mRNA compared to control cells transduced with an “empty” reporter lentiviral vector. Prior to differentiation, the DGAT1 overexpressing preadipocytes showed elevated intracellular TAG accumulation and the formation of distinct lipid droplets, whereas the control cells did not demonstrate this behaviour. After differentiation, the increase in lipid was unexpectedly not maintained, characterised by a lower rate of lipogenesis and smaller adipocyte size. Assessment of adipocyte interactions with RAW 264.7 macrophages revealed both the recombinant DGAT1 and control vectors were associated with elevated inflammatory gene expression in response to macrophage secretions. Similarly, exposure to adipocyte secretions obtained from both populations of the transduced 3T3-L1 cells led to increased RAW 264.7 macrophage activation compared to secretory factors collected from non-transduced adipocytes. Genetic manipulation of 3T3-L1 cells by lentiviral transduction led to elevated inflammation which appeared to be due to activation of an immune response to the vector. Overexpression via the recombinant DGAT1 vector resulted in an unexpected reduction in adipocyte size which did not occur in the transduced control cells despite both populations having an impaired inflammatory profile. This loss of adipogenic behaviour was likely attributable to interference with the complex differentiation process due to an excessively high gene expression load, rather than the DGAT1 transgene itself. These results emphasise the need to exercise caution when using genetic manipulation techniques with the 3T3-L1 cell line, particularly because changes in inflammatory profile can occur without alterations in observable traits and may therefore be difficult to detect.

▼ HIV currently infects 35 million people worldwide and antiretroviral treatments are expensive, lifelong, and fail to provide a cure. Gene therapy provides an alternate approach to the treatment of HIV. I investigated the effects of two therapeutic genes both singly and in tandem: the fusion inhibiting membrane anchored peptide maC46 (C46), and a short-hairpin RNA to CCR5 (sh5) which downregulates expression of the CCR5 receptor. These genes were carried on lentiviral vectors which were transduced into cell lines and PBMC. The vectors were named Control, C46, sh5 and Dual. The therapeutic genes conferred selective advantages in the presence of the R5tropic HIV-1BaL, with the Dual construct displaying the strongest selective advantage as Dual gene-containing cells expanded significantly faster than either single-gene vector. Both the sh5 and Dual vectors conferred a survival advantage for the cultures, with significant resistance against cell death, as well as strong inhibition of viral replication. The therapeutic genes also conferred protection against pseudotyped HIV in single round infection assays, with the Dual construct performing the best and with the greatest consistency. While most protection conferred in Molt4/CCR5 was paralleled in PBMC, the sh5 construct yielded differing results in PBMC. The most likely explanation is that among the cells that comprise PBMC, some of them may express other receptors which can be utilised by the HIV strains used. Cells containing the therapeutic genes were also challenged to assess their potential to trap HIV on their surface. Results indicated the C46 (and Dual)-marked cells mediated viral trapping of HIV-1NL4-3. However, HIV-1BaL virion trapping was observed on sh5 and Dual marked cells, yet C46-marked cells behaved differently. Microscopy indicated potential viral trapping on C46-marked cells, while flow cytometric analysis showed that this virus was more likely within the cell membrane. This indicated that the processes of viral entry may differ (by more than just co-receptor use) between HIV-1NL4-3 and HIV-1BaL.The work conducted here points to there being complex interactions between virus and host cells around the points of viral attachment and entry. However, even with these undefined processes taking place, the combined gene therapy consistently provided the best protection on every metric assessed.

▼ Die Suppression von autoreaktiven T-Zellen ist eine Funktion von CD4+CD25+ regulatorischen T-Zellen (CD4+CD25+ Tregs). CD4+CD25+ Tregs unterdrücken autoaggressive Immunantworten. Galectin-10 und Foxp3 sind wichtige Proteine, die an dem supprimierenden Mechanismus der Tregs beteiligt sind. Galectin-10 ist eines der ältesten bekannten humanen Proteine, die nicht in anderen Spezies gefunden worden sind. Foxp3 ist ein Transkriptionsfaktor, der in menschlichen CD4+CD25+ Tregs und in CD4+CD25- T-Effektor-Zellen nach Aktivierung exprimiert wird. Ein siRNA-vermittelter Knockdown dieses intrazellulären löslichen Proteins hebt die supprimierende Funktion der humanen CD4+CD25+ Tregs auf.rnDiese Arbeit beinhaltet in vitro durchgeführte Untersuchungen zur Ermöglichung eines Knockdown von Galectin-10 und/oder Foxp3 in humanisierten Mäusen. Es war möglich, ein Verfahren für die Produktion von lentiviralen Partikeln zu etablierten, die sich als effizientes Vehikel für den Gentransfer in humane Stammzellen und verschiedene Tumor- und Immunzellen erwiesen. Nach der Transduktion von AML14.3D10 Tumorzellen mit GFP-codierenden lentiviralen Partikeln konnte eine langfristige Expression von GFP erreicht werden. Außerdem war es möglich lentivirale Partikel zu erzeugen, die mit shRNA gegen Galectin-10 codiert waren. Die erzeugten Partikel erwiesen sich als funktionell, indem sie eine deutliche Herunterregulation von Galectin-10 in konstitutiv Galectin-10 exprimierenden AML14.3D10 Tumorzellen bewirkten. Unsere Studie präsentierte außerdem eine erstmalige Untersuchung zum Nachweis von Galectin-10-Protein in Eosinophilen aus humanen CD34+ hämatopoetischen Stammzellen (HSC). Diese stabile in vitro Galectin-10-Expression bietet ein alternatives Untersuchungsmodell zu CD4+CD25+ Tregs, die nicht aus CD34+ HSC differenziert werden können. Der zusätzliche Einbau des GFP-Gens in die mit shRNA gegen Galectin-10 codierende lentivirale Partikel war ein wichtiger Schritt zur Markierung von Zellen, die einen Galectin-10-Knockdown aufwiesen. Die neuen bicistronischen lentiviralen Partikel erwiesen sich sowohl in aus CD34+ HSC differenzierten Eosinophilen als auch in AML14.3D10 Zellen, die einen eosinophilen Phänotyp aufweisen, als funktionell. Schließlich konnte mit den bicistronischen lentiviralen Partikeln, die mit GFP und shRNA gegen Foxp3 codiert waren, eine Herunterregulation von Foxp3 in CD4+CD25- T-Effektor-Zellen erreicht werden, was erneut die erfolgreiche Herstellung von funktionellen lentiviralen Partikeln bewies.rn

▼ Artrite Encefalite Caprina é uma enfermidade infecciosa, multissistêmica, causada pelo vírus da Artrite Encefalite Caprina, que pertence dentre os Lentivírus de Pequenos Ruminantes. Sobre o aspecto reprodutivo na transmissão, o objetivo do presente estudo consiste em avaliar experimentalmente a transmissibilidade do lentivírus caprino em cabras e suas crias pela placenta e sêmen. Para avaliar a influência da transmissão via placentária, foram utilizadas cinco fêmeas com CAEV inseminadas artificialmente com sêmen de bode livre de CAEV. Para avaliar a influência da transmissão pelo sêmen, foram utilizadas seis fêmeas livres de CAEV inseminadas artificialmente com sêmen de bode livre de CAEV. O CAEV-Cork foi adicionado ao sêmen fresco com a finalidade de se obter título infectante com carga viral em 105 TCID50/mL. Como grupo controle, duas cabras livres de CAEV foram inseminadas artificialmente com sêmen de mesmo bode sem o inóculo viral; e outras duas cabras com CAEV inseminadas com a carga viral. As fêmeas foram monitoradas durante a gestação até 15 dias pós-parto e as crias separadas das mães foram monitoradas até 12 meses de idade, empregando-se as técnicas de IDGA, cELISA e nested-PCR. As fêmeas com CAEV apresentaram resultados positivos em IDGA (87,10%), cELISA (88,71%) e nested-PCR (25,81%). As crias apresentaram resultados negativos em ambos os testes de IDGA e cELISA, embora na técnica de nested-PCR, 7,14% das amostras apresentaram banda positiva. Das seis fêmeas livres de CAEV, quatro (66,67%) apresentaram soroconversão com 18,46% das amostras positivas ao IDGA, 49,23% das amostras positivas ao cELISA e nenhuma para nested-PCR. Anticorpos anti-CAEV foram detectados 30 dias pós IA. Quanto às crias, 5,26% e 11,28% das amostras apresentaram resultado positivo para IDGA e nested-PCR, respectivamente. Nenhuma amostra apresentou positividade para cELISA. O grupo controle livre de CAEV tiveram resultados negativos para as três técnicas, incluindo suas crias; enquanto que as fêmeas com CAEV inseminadas com o inóculo viral apresentaram 61,90% das amostras positivas para IDGA, 100% para cELISA e nenhuma amostra para nested-PCR. Suas crias obtiveram no total somente um resultado positivo para IDGA e outro para nested- PCR. A positividade encontrada em nested-PCR nas crias pode ter um significado particular de identificar animais infectados porém soronegativos, como em situações de soroconversão tardia. Entretanto, não é possível assumir a transmissão do CAEV para crias de forma insofismável, embora não é descartada a possibilidade de infecção das crias pelo sêmen e placenta com soroconversão tardia. Contudo é possível a transmissão do CAEV por IA com sêmen infectado em fêmeas livres de CAEV. A carga viral utilizada no estudo foi capaz de infectar as fêmeas. Com relação aos testes utilizados, o cELISA detectou a soroconversão mais cedo que o IDGA. A técnica de nested-PCR falhou em detectar a infecção antes da soroconversão nas fêmeas. Este estudo proporcionou maiores informações sobre a transmissão do lentivírus caprino…

▼ Notre laboratoire a développé un prototype de vaccin unique contre le VIH-1 / SIDA. C'est un un lentivecteur ADN non-intégratif qui a été testé dans une étude pilote utilisant des modèles animaux. L'étude a montré la protection de tous les macaques (6/6) vaccinés et la réponse était composée de cellules effectrices (EM) et des cellules T mémoire centrale (CM). Plus important encore, elle contenait également des cellules antigène spécifique à haute capacité de prolifération contenant des cellules T mémoire de type cellule souche (TSCM). Durant le travail de cette thèse, le génome vaccinal a été encore amélioré en commutant son enveloppe dotée de tropisme CXCR4 contre des enveloppes à tropisme CCR5 de virus de clade B (WARO) obtenu à partir d'un patient infecté de façon chronique et de trois souches de VIH-1 de Clade C transmetteur foundateur (T/F) de patients Zambiens. Une deuxième amélioration du vaccin a été réalisée en modifiant le génome afin qu’il puisse incorporer des adjuvants moléculaires capables d'améliorer d’avantage son immunogénicité.Etant donné que le
lentivirus humain VIH-1 a développé plusieurs stratégies complexes pour persister, l’autre partie de la thèse a été consacrée à développer un outil pour comprendre la latence dans les cellules T CD4 + de la mémoire infectée. Les cellules latentes ont des génomes d'ADN viral intégrés non exprimés. Un des principaux mécanismes de cette latence est l'absence de transactivation du promoteur LTR par Tat. Les développements récents de la thérapie antivirale hautement active (HAART) efficace pour contrôler les cellules infectées circulantes et dans les tissus reste inefficaces contre les cellules du réservoir composé de cellules infectées latentes. Un des obstacles pour ce type d'études est l'absence de prototypes de
lentivirus de primates appropriés incapables de d’effectuer la latence pour s’en servir comme modèle d'infection extrême dans l'évaluation. Nous avons émis l'hypothèse qu'un génome SHIV réplicatifdont l’expression est sous le contrôle de LTR du CAEV, Tat-indépendant doté de promoteur constitutif constituera un outil précieux pour de telles études. Nous avons conçu des LTRs chimères de CAEV portant les séquences d'attachement de celles du SIV à leurs extrémités et nous les ont utilisés pour contrôler l’expression du génome complet de SHIV-KU2. La construction résultante est SHIV-YCC qui devrait générer un virus qui ne n’effectue pas de latence en absence de Tat. Nous avons observé que les cellules transfectées avec le génome SHIV-YCC produisent des protéines SHIV qui s’assemblent en particules infectieuses excrétées des cellules. Les virions sont capables d'infecter les lymphocytes T CD4 + cibles tant dans les PBMC primaires que dans les lignées cellulaires. Le passage en série du virus dans les PBMC de macaques augmente la réplication et l'infectiosité du virus. SHIV-YCC est le premier
lentivirus chimérique réplicatif de primates qui exprime de manière constitutive toutes les protéines virales. Ce nouveau modèle offre la possibilité d'étudier les…

▼ Le syndrome d'immunodéficience acquise (SIDA) est une maladie provoquée chez l'homme par le virus de l'immunodéficience humaine (VIH), un lentivirus à ARN monocaténaire qui infecte les cellules humaines qui expriment les CD4 à leur surface. Depuis son apparition en 1982 chez l’homme, il y a eu environ 80 millions d'individus infectés dans le monde et près de la moitié d'entre eux sont déjà décédés. Aucun vaccin n'existe actuellement mais l'espérance de vie d’un grand nombre de patients est maintenant prolongée grâce au développement et la disponibilité d'un traitement antirétroviral hautement actif (HAART en anglais). En raison de la complexité des interactions hôte/pathogène liées à l'infection par le VIH-1 chez l'homme et les modèles primates non-humains actuels, le développement d’un modèle plus simple est nécessaire pour étudier et mieux comprendre les mécanismes sous-jacents de l'augmentation de la pathogenèse du VIH-1 chez l’humain. Dans ce but, un virus chimérique CAL-HIV-R1 a été construit dans notre laboratoire en échangeant les longues séquences répétées terminales (LTR) du VIH par celles du CAEV, un lentivirus caprin. Parce que ces LTR de CAEV ont un promoteur constitutif qui est indépendant du trans-activateur de la transcription, ce virus chimérique ne devrait pas subir de latence dans les cellules T CD4+ mémoire. Pour rendre son efficacité réplicative plus performante, cette chimère a subi plusieurs passages successifs sur des cellules humaines en culture. En plus de la présence de son récepteur primaire, la protéine CD4, le VIH doit interagir avec une seconde molécule co-réceptrice pour entrer dans la cellule hôte. Des clones moléculaires infectieux contenant des génomes proviraux complets de plusieurs isolats de VIH-1 ont été reçus de la banque de produits "NIH AIDS Reagent Program Repository". Trois d'entre eux, à savoir pNL4-3, p89.6 et WARO, ont été utilisés pour produire des stocks de virus après transfection des cellules de la lignée humaine HEK-293T et utilisés pour infecter d’autres lignées cellulaires telles que : 1) des cellules GHOST, utilisées pour examiner le tropisme des virus en fonction de leur utilisation des co-récepteurs et qui sont respectivement X4, X4/R5 et R5; 2) la lignée cellulaire M8166, utilisée comme cellules indicatrices du fait de ses propriétés fusogéniques, et qui sert à examiner les capacités de réplication et enfin, 3) la lignée cellulaire TZM-bl utilisée pour évaluer le titre infectieux des virus. Par ailleurs, un vaccin basé sur un vecteur ADN lentiviral chimérique, le CAL-SHIV-IN-, a été développé au laboratoire et testé chez des macaques. Dans le cadre de cette étude, un test de séro-neutralisation a été réalisé sur des échantillons de sérum des macaques vaccinés avec ce vecteur, et des animaux témoins, pour examiner la présence d'anticorps pouvant neutraliser le virus. Bien que des anticorps furent présents aucune capacité neutralisante n'a pu être détectée.

▼ O Brasil possui atualmente o segundo maior rebanho de eqüídeos do mundo e a Eqüideocultura Brasileira desempenha um importante papel no desenvolvimento do setor de agronegócios. Entre as doenças infecciosas que afetam a eqüinocultura nacional, a Anemia Infecciosa dos Eqüinos (AIE) tem se mostrado de difícil controle. A AIE é causada por um retrovírus, apresenta uma distribuição mundial, e é reconhecida como a mais importante doença dos eqüinos. Entre os sinais clínicos mais comuns, na fase aguda da doença, encontram-se a anemia seguida de icterícia nas mucosas, edema ventral, mioglobinúria, caquexia e, principalmente, febre intermitente. Como não há tratamento, Ministério da Agricultura, Pecuária e Abastecimento (MAPA) determina, através de mecanismo legais, uma política de exame obrigatório em laboratórios credenciados, para o transporte e comercialização de eqüídeos no País. O exame é baseado na prova de Coggins, uma imunodifusão em ágar gel do soro do animal testado contra antígeno do vírus da AIE. Como a infecção é vitalícia, animais soropositivos são eutanasiados por Médicos Veterinários do MAPA. Considerando que a precisão dos resultados é crítica, posto que animais falso positivos podem ser sacrificados inutilmente, e falso negativos preservados como fonte de infecção, surgiu o interesse de um análise sistemática da reprodutibilidade dos kits e possíveis fontes de erro no diagnóstico. Para esta finalidade, soros positivos e negativos, referenciados pela repetição dos testes de Coggins e ELISA, foram avaliados pela prova de IDGA, comparativamente com três kits de diferentes fabricantes. Nos experimentos de reprodutibilidade, observou-se uma grande distinção na qualidade da linha de precipitação promovida pelos soros positivos nos testes nos diferentes kits. Este fenômeno pode ser justificado pela utilização das condições técnicas legais, determinadas por portaria do MAPA, que são distintas das recomendações dos fabricantes de dois dos kits analisados. Mesmo assim, a avaliação da reprodutibilidade dos resultados dos kits com os soros referenciados mostrou elevada correlação.
Brazil has currently the second bigger flock of equines of the world and the brazilian equines breeding plays an important role in the development of the sector of agribusiness. Among the infectious disease that affect the national equines breeding, the Equine infectious anemia (EIAV) has been shown of difficult control. The Equine infectious anemia is caused by a retrovirus, it has a worldwide distribution, and it is recognized as the most important disease of equines. The most common clinical signals in the acute phase, are anemia followed of jaundice in the mucosae, ventral oedema, mioglobinury, caquexy and, mainly, intermittent fever. Once it has no treatment, Ministry of Agriculture, Cattle and Supplying determines, through legal mechanisms, a politics of obligatory examination in credentialed laboratories, for the transport and commercialization of equines in the country. The examination is based on the test of Coggins, an…

▼ Les rétrovirus VIH-1 et 2 responsables du SIDA, bien que très similaires sur le plan de leur organisation génomique, diffèrent par leurs protéines auxiliaires. Ces dernières inactivent des facteurs cellulaires antiviraux et permettent ainsi l'établissement d'un environnement cellulaire favorable à la réplication virale. Vpx, une protéine auxiliaire spécifique du VIH-2, est connue pour sa capacité à augmenter l'infection virale, une activité longtemps reliée à son unique faculté à contrecarrer SAMHD1, un facteur de restriction actif à l'étape de transcription inverse. Cependant, plusieurs éléments de la littérature suggèrent que Vpx confère un avantage au virus indépendamment de SAMHD1. Nous avons donc étudié la possibilité d'une cible supplémentaire inactivée par Vpx et, à partir d'un crible protéomique, nous avons identifié le complexe HUSH (HUman Silencing Hub). Composé de TASOR, MPP8 et Periphilin, le complexe HUSH est impliqué dans le control épigénétique de transgènes intégrés ainsi que des éléments transposables Line-1. Nous avons montré la capacité de Vpx à lier le complexe HUSH et à induire sa dégradation par le protéasome grâce au détournement de l'adaptateur d'ubiquitine ligase DCAF-1 et ce, de façon indépendante de SAMHD1. De ce fait, Vpx est capable de réactiver des provirus latents du VIH, contrairement à des mutants de Vpx incapables d'induire une dégradation de HUSH. Bien que l'antagonisme du complexe HUSH humain ne soit pas conservé au sein de toutes les lignées lentivirales, y compris le VIH-1, il est une caractéristique de certains Vpr des VIS des singes verts africains ainsi que du VIS divergent du singe de l'Hoest. Le caractère ancien de cette fonction post-intégrative insoupçonnée des gènes vpx/vpr, ainsi que la spécificité d'espèces observée, sont deux critères favorables au statut de facteur de restriction pour le complexe HUSH. Dressant ainsi le contrôle épigénétique comme barrière de l'immunité intrinsèque, nécessaire au maintien de l'intégrité du génome cellulaire.
HIV-1 and 2 are both responsible for AIDS, though similar, these two retroviruses harbour different sets of auxiliary proteins. Through the inactivation of cellular antiviral factors, these auxiliary proteins allow the establishment of a favourable environment for viral replication. Vpx, an HIV-2 only auxiliary protein, is known for its ability to increase viral infection, which was long linked to its sole capacity to counteract SAMHD1, a restriction factor active at the reverse transcription step. However, several lines of evidence suggested a SAMHD1-independent advantage of Vpx. We therefore investigated the possibility of an additional Vpx target and through a proteomic screen, we identified the HUman Silencing Hub (HUSH) complex. HUSH complex, including: TASOR, MPP8 and Periphelin, was reported to epigenetically silence integrated transgenes and recently Line-1 transposable elements. Here, we show that Vpx binds the HUSH complex and induces its proteasomal degradation through the hijacking of the DCAF-1 ubiquitin ligase…

▼ Clinical virotherapy has been successfully approved for use in cancer treatment by the US Food and Drug Administration (FDA). Innovative treatment of cancer, oncolytic viruses is a new treatment of cancer, with different type of virus families to evaluate different disease in clinical trials and increase viral applications. During the past decade viral vehicles constructed from HIV-1, the best characterized of the lentiviruses, have been established.
Lentivirus based on HIV-1 are capable of infecting a wide variety of dividing and non-dividing cells, integrate stably into the host genome, and result in long term expression of the transgene. However, one of the most important technical solutions needed for clinical virotherapy is improved systemic virus delivery. Achieving efficacious and accurate systemic delivery will greatly broaden opportunities in virotherapy. Furthermore, magnetic nanoparticles provide accelerated vector accumulation in target sites when directed with magnetic field-enforced delivery. In this study, we show that
lentivirus chemically conjugated with iron oxide nanoparticles (~ 5nm) have remarkable ability to be remotely guided under magnetic field. Transduction is achieved with micro-scale precision. Furthermore, a gene for shRNA (short hairpin RNA) production was introduced into the
lentivirus genome to enable RNA interference (RNAi).

▼ Atherosclerosis is an inflammatory disorder triggered by an accumulation of cholesterol in macrophage-derived foam cells. Adherence of these cells to the vascular endothelium, leads to cardiovascular disease. Removal of excess cellular cholesterol is essential to maintain a balanced cellular lipid profile and to oppose the development of atherosclerosis. The ATP-binding cassette transporter A1 (ABCA1) mediates the unidirectional efflux of excess cholesterol and phospholipids from foam cells to lipid-poor apolipoprotein A-I, in a process called reverse cholesterol transport, resulting in high-density lipoprotein (HDL) biogenesis. Lipoprotein lipase (LPL) is a lipolytic enzyme expressed by macrophages within atherosclerotic lesions, and is considered proatherogenic. The aim of this study was to investigate the regulatory effects of LPL on ABCA1-mediated cholesterol efflux. This was accomplished using three approaches:
lentivirus-mediated LPL gene silencing, chemical inhibition of LPL, and exogenous addition of LPL to the cell culture medium. First, stable THP-1 macrophage cell lines exhibiting LPL knockdown and LPL overexpression were successfully created, and confirmed using PCR methods. Since the level of LPL overexpression was modest, the rest of the study focused on the LPL knockdown cell line. Down-regulation of LPL protein levels was confirmed by metabolic labeling using 35S-methionine. Suppression of LPL expression increased ABCA1 mRNA levels, however there was no increase in ABCA1 protein levels detected through Western blotting. Furthermore, genes for the other modes of cholesterol efflux, ABCG1 and SR-BI, were down-regulated by 12% and 19%, respectively, in LPL knockdown cells. Knockdown cells, when used in a cholesterol efflux assay, revealed a significant increase in ABCA1-mediated cholesterol efflux compared to wild-type cells.
The second approach was to inhibit LPL function in WT cells. Orlistat, an inhibitor of LPL lipase activity, when added to the culture medium, up-regulated ABCA1-independent cholesterol efflux. A LPL-specific antibody was used to inhibit the adapter function of LPL. Such an approach has been shown to interfere with the ability of LPL to promote apoA-I binding to the cell surface. The presence of anti-LPL IgY also up-regulated ABCA1-independent cholesterol efflux. Last, the addition of exogenous LPL resulted in a down-regulation of ABCA1-mediated cholesterol efflux in both wild-type and knockdown cells. These findings suggest an inverse correlation between LPL levels and ABCA1 cholesterol transport activity.

▼ PRAS40 and DEPTOR are mTOR binding proteins that affect cell metabolism. Under catabolic conditions such as sepsis and glucocorticoid excess, there is an increase in total DEPTOR protein and a reduction in phosphorylation of PRAS40, suggesting that these proteins may modulate the mTOR-mediated protein synthetic response under normal and diseased conditions. The hypothesis of the present study was that knock down (KD) of PRAS40 or DEPTOR in C2C12 myocytes will increase protein synthesis via stimulating mTOR-S6K1 signaling. PRAS40 and DEPTOR KD was achieved using lentiviral particles containing shRNA to target the mouse PRAS40 and DEPTOR mRNA sequence, whereas control cells were transfected with a scrambled control shRNA. KD reduced PRAS40 and DEPTOR mRNA and protein content by 90%. PRAS40 KD did not result in increased phosphorylation of mTOR substrates or increased protein synthesis, whereas, DEPTOR KD increased both phosphorylation of mTOR kinase substrates, 4E-BP1 and S6K1, and protein synthesis. The responsiveness of PRAS40 and DEPTOR KD myocytes to anabolic (IGF-I) and catabolic (AICAR) stimuli was unaltered. Both PRAS40 and DEPTOR KD myoblasts were larger in diameter and exhibited an increased mean cell volume compared to scramble control. PRAS40 KD cells had decreased phosphorylation (S807/S811) of pRb protein. In contrast, DEPTOR KD cells had an increased phosphorylation (S807/S811) of pRb protein which is critical for the G1-S phase transition, coincident with an increased percentage of cells in the S phase. Neither PRAS40 nor DEPTOR KD altered myoblast apoptosis as evidenced by the lack of change for cleaved caspase-3. Although DEPTOR KD myoblasts did not alter autophagy as determined by a lack of change in the ratio of LC3BII/LC3BI, PRAS40 KD myoblasts had a reduced ratio of LC3BII/LC3BI. While PRAS40 KD delayed myotube formation concurrent with delayed proliferation, DEPTOR KD had the opposite effect on myogenesis and proliferation. Finally, while in vivo DEPTOR KD (~50% reduction) by electroporation into the muscle of C57/BL6 mice did not alter weight or protein synthesis in the control muscle, it prevented atrophy produced by 3 days of hindlimb immobilization, at least in part by increasing protein synthesis. Thus, our data support the hypothesis that PRAS40 and DEPTOR are important regulators of protein metabolism in myocytes and demonstrate that, while PRAS40 is required for normal myoblast growth and function, decreasing DEPTOR expression is sufficient to ameliorate the atrophic response produced by immobilization.

▼ RNA interference (RNAi) is a means of regulating gene expression by targeting
mRNA in a sequence-specific manner for degradation or translational inhibition. Short
hairpin RNAs (shRNAs) and short interfering RNAs (siRNAs) have been extensively
employed for manipulating gene expression in a wide range of species. The goal for this
research was to produce transgenic livestock in which myostatin, a negative regulator of
muscle growth, has been targeted for silencing by RNAi. This would demonstrate the
utility of RNAi for reducing gene expression in large animal species. To successfully
target the myostatin gene for reduction, siRNAs were designed to target the both the
bovine and caprine myostatin mRNA sequence. These were then tested for effectiveness
in vitro using both an HEK 293T cell line expressing caprine myostatin as well as adult
bovine muscle cells. The most effective siRNA, GDF8-1026, was cloned into a lentiviral
plasmid and used to transduce bovine fetal fibroblasts for somatic cell nuclear transfer
cloning as well as perivitelline injection of in vitro produced bovine embryos. To date,
seven pregnancies have been established using these two methods.
Concern over the possibility of off-target effects associated with the expression
of shRNAs in vivo prompted investigation into tissue-specific expression. Therefore,
investigation into the use of a muscle-specific promoter to drive transgene expression
was pursued. The bovine myogenin promoter and muscle creatine kinase (MCK)
promoter were cloned into a lentiviral plasmid and evaluated in bovine fetal muscle cells
and mouse C2C12 cells in vitro for their ability to drive GFP expression. Both promoters
demonstrated an increase in GFP intensity at day nine of differentiation when compared
to the nontransduced control.
The retroviral basis of lentiviral plasmids has raised concern over the possible
development of replication competent
lentivirus (RCL). Therefore, analysis of tissues
from recipients of
lentivirus-treated embryos was performed to detect possible RCL.
Tissues and blood serum were tested for RCL using p24 ELISA as well as qRT-PCR for
the VSV-G gene. To date all tissues tested so far shown no evidence for RCL using these
analyses. Analysis of offspring transgenic for an shRNA targeting myostatin will allow
confirmation of RNAi as a useful tool for manipulating gene expression in large animal
species.

▼ Equine infectious anemia virus (EIAV) is a macrophage-tropic
lentivirus of horses. EIAV is unique among lentiviruses in that a further cleavage event occurs within the N-terminus of the cytoplasmic tail (CT) of transmembrane (TM) glycoprotein and yields a C-terminal non-glycosylated p20 protein. The p20 comprises more than two-third of the CT domain and contains both of the amphipathic α-helices.
To test the role of the EIAV CT domain in acute disease induction, we constructed a p20-truncated clone (p19/wenv17Δ20) on the background of a highly virulent EIAV infectious clone p19/wenv17 by introducing three termination codons into the N-terminal coding region of p20. The derived virus replicated at a delayed and lower level compared with that of parental virus in equine macrophages in vitro. In vivo, the p19/wenv17Δ20 virus showed attenuation and did not induce acute disease like the parental (p19/wenv17) virus. The viral load in ponies infected by p19/wenv17Δ20 virus was about 10-1000 fold lower than that of ponies infected by parental (p19/wenv17) virus. In vitro studies on the properties of the p20-truncated virus showed that truncation of the p20 did not impair the envelope glycoprotein incorporation into virions. There was also no severe defect in virus replication. The delayed and lower level replication of p20-truncated virus compared with parental virus was most probably due to small delays in several steps in the virus life cycle. In addition, p20 expressed in trans could not compensate for the absence of p20 in the p20-truncated virus.

▼ Cystic Fibrosis (CF) is the most common, fatal autosomal recessive disorder affecting the Caucasian population with a frequency of 1 in 2500 live births and has a current median survival age of approximately 33 years. Characteristics of CF include abnormalities in sweat glands, malnutrition, pancreatic disease and infertility. It is however, severe and chronic lung disease that currently accounts for greater than 95% of morbidity and mortality in CF patients. The CF transmembrane conductance regulator gene was discovered in 1989 and in vitro correction of the defect soon followed, providing the basis for gene therapy as a potential cure for CF lung disease. To date, the lack of an efficient gene transfer vector system combined with the physical barriers of the airway epithelium limit the successful application of CF gene therapy. The work described in this thesis utilised a unique gene therapy approach developed by the CF Gene Therapy Research Group, which involved airway pre-treatment followed by gene delivery. Pre-treatment was with the natural detergent lysophosphatidylcholine (LPC), followed by a single-dose of a HIV-1 based
lentivirus (LV) vector in vivo. Previously studies found significant gene expression within airway tissues, but areas of cell damage were also sometimes evident. Initial work included examining the relationship between gene transfer, LPC dose and timing parameters, and airway epithelial damage. This study found that 0.3% LPC
followed 60 minutes later with the LV produced significant gene expression within the airway, with only mild airway epithelial disturbance observed. The longevity of LV-mediated gene expression was then evaluated in the nasal airway of C57Bl/6 mice using the LacZ marker gene. Treatment of mouse nasal airway epithelium with the LPC prior to instillation of a single dose of an LVLacZ vector produced significant LacZ gene expression in many mice for at least 18 months. The finding of gene expression in one mouse after 24 months indicated essentially lifetime gene expression had been achieved. We found that a single dose of LVLacZ produced immediate as well as lifetime mouse airway expression, confirming our hypothesis that use of an integrating vector extends transgene expression. Importantly, LVCFTR dosing achieved at least 12 months of CFTR expression, representing partial functional correction of the CFTR defect in CF knockout mice. These findings provide evidence that a single-dose Lentiviral gene transfer method may offer a novel in vivo therapeutic paradigm in the pursuit of a cure for CF airway disease.

▼ Lysyl oxidase like-2 (LOXL2) was found to be present extracellularly in primary human gingival fibroblast cells. This project has been primarily focused on investigating our hypothesis that LOXL2 may play a critical role in regulating cell proliferation and collagen accumulation in primary human gingival fibroblast cells, which may contribute to the development of fibrotic changes in human gingival tissue. LOXL2 shRNA lentivirus reduced the LOXL2 mRNA and protein expression by 90 – 95%. Knockdown of LOXL2 or inhibition of LOXL2 enzymatic activity strongly inhibited both basal and CCN2/CTGF-stimulated collagen accumulation (p<0.05). Proliferation assays demonstrated a marked decrease in cell proliferation in both the short and long term in LOXL2 shRNA knockdown cells with minimal or no stimulation of cell apoptosis. Pharmacologic inhibition of LOXL2 enzyme activity reduced basal and CCN2/CTGF-stimulated cell proliferation (40% and 50%) in short term cultures. Furthermore, there was 15-20% inhibition seen in long term assays. Recombinant active LOXL2 significantly increased collagen accumulation and cell proliferation (p<0.05). Thereby, our investigation in vitro by loss and gain of function experiments confirmed that LOXL2 is critically required for both gingival fibroblast proliferation and for collagen accumulation in the presence or absence of CCN2/CTGF. LOXL2 stimulation is critical for both proliferation and collagen accumulation in primary human gingival fibroblasts. Lastly, we found that the presence of LOXL2 extracellularly and LOXL2 may regulate cell proliferation by enhancing the phosphorylation of PDGFR.

▼ Localizing the drug at the site of action is one of the most important goals of drug delivery systems. This requires developing a vehicle which is able to protect drug carriers from degradation, while delivering the drug of interest to the specific tissue. In this study, a novel recombinant protein RGD-CD47-Streptavidin was synthesized to modify the surface of the drug carriers, and thereby allow them to surpass the mononuclear phagocyte system and deliver the drug of interest directly to target cancer cells. The recombinant protein was made and purified using a unique solution containing low concentration of the non-ionic detergent Triton X-100 followed with alkaline buffer. The purified protein was characterized by the western blot analysis and its tumor tropic and antiphagocytic functionality was confirmed by the cell assay.
Non-viral and viral drug carries were both functionalized with the recombinant multifunctional protein. As a model of non-viral drug carriers, 1.510
7 biotin coated polystyrene particles (150, 560 and 840 nm) were coated with various concentrations of the recombinant fusion protein. Flow cytometry and J774A.1 macrophage cell studies revealed that CD47 immobilized on the various size of particles significantly reduced phagocytosis for 8 hours. However, the soluble CD47 decreased the phagocytes’ particle engulfment just for 2 hours. The phagocytosis index was decreased by increasing the CD47 density on the particle surface. The results demonstrated that presence of 116.49, 45.33 and 287.58 µg/µm
2 of CD47-SA respectively on the surface of 840, 560 and 150 nm particles, decreased 50% of phagocytosis after 4 hours. To functionalize viral vectors with the multifunctional protein,
lentivirus encoding eGFP was obtained from 293T producer cells and biotinylated by host-cell-assisted labeling strategy. The biotinylated
lentivirus was coated with recombinant fusion protein RGD-CD47-SA and characterized by immunoblot analysis. The antiphagocytosis cell study and flow cytometry analysis demonstrated that CD47 self-marker protein potentially inhibited
lentivirus uptake by macrophages and therefore decreased infectivity of the virus in comparison with non-CD47 coated virus.
To examine the tumor targeting of the protein, the 560 nm polystyrene particles were coated with CD47-SA and RGD-CD47-SA recombinant fusion protein separately. The coated particles were able to escape from macrophage engulfment by 8 hours. The association of coated particles with integrin α
vβ
3 was demonstrated in the highly expressed integrin colorectal cancer cells (HT29) and adenocarcinomic human alveolar basal epithelial cells (A549). The polystyrene particles coated with CD47-SA were able to bind to the integrin α
vβ
3 expressed on the surface of the A549 and HT29 cells but not stronger than the particles coated with RGD-CD47-SA. After blocking the integrin α

▼ The mammalian immune system must be dynamic in the face of a diverse and ever-changing array of pathogens. Successful pathogens have evolved to overcome host immunity. One of the most successful pathogens in the last century is the human immunodeficiency virus (HIV), which is the etiological agent responsible for the global acquired immune deficiency syndrome (AIDS) epidemic. Currently, one of the most studied host-pathogen interactions is between the cellular anti-retroviral APOBEC3 (A3) proteins and HIV viral infectivity factor (Vif) protein. A3 proteins are cytosine deaminases that primarily inhibit retroviruses and retrotransposons by mutating cytosines to uracils in retroviral DNA during reverse transcription. When HIV Vif is present, it can bind to certain A3 proteins and recruit cellular degradation complexes to target these anti-retroviral proteins for proteasomal degradation. HIV-like viruses (lentiviruses) infect other mammals and are the inspiration for studying A3 proteins in other mammals. The ultimate goal of this comparative study was to gain a better understanding of how the lentiviral Vif protein counteracts host A3 proteins.
The first component of this dissertation is dedicated to the process of determining the complete A3 protein repertoires of cow and sheep (representatives of the artiodactyl lineage), which are both infected with a lentiviruses. The second component of this dissertation was to test if these artiodactyl A3 proteins were functional. Cow and sheep A3 proteins demonstrate intrinsic DNA cytosine deaminase activity and localize in cells similar to human A3 proteins. Furthermore, certain cow A3 proteins are capable of restricting HIV and are neutralized in the presence of cattle-specific lentiviral Vif (bovine immunodeficiency virus). The last component of this dissertation, a panel of conserved mammalian A3 proteins were tested to determine if each A3 protein interacts specifically with its species lentiviral Vif protein. It was shown that each representative host A3 protein is degraded in the presence of its species specific lentiviral Vif, suggesting a conserved interaction between mammalian A3 proteins and their species specific lentiviral Vif protein.

▼ We investigated the use of a replication-defective
human immunodeficiency virus-based
lentivirus vector pseudotyped
with VSV.G for GFP gene transfer to primary rat alveolar epithelial
cells (AEC's). Cells grown on plastic exhibited a dose response
with transduction efficiencies of 99% at an MOI's of 50.
Importantly, comparison of
lentivirus-mediated gene transfer from
the apical or basolateral surface of confluent and polarized
monolayers of AEC's cultured on semi-permeable supports revealed
efficient transduction only when
lentivirus was applied apically.
Manipulating the tight junctions of the monolayers did not enhance
infection, indicating that transduction occurred primarily at the
apical membrane. In contrast, differentiated tracheal epithelial
cells could only be transduced apically in the presence of EGTA but
even then at a much lower overall efficiency (15-fold) than was
observed for AEC's suggesting that receptor localization may differ
between upper and lower airways.; To determine if these vectors
could deliver a functional transgene we set out to study sodium
pump activity after gene transfer of the alpha1- or beta1 sodium
pump subunits of rat Na+,K+-ATPase. Transduction with
Lenti-beta1-EGFP was accompanied by coordinate up-regulation of
endogenous alpha1 expression, whereas endogenous beta1 expression
was unchanged after transduction with Lenti-alpha1-EGFP. Consistent
with these findings, transduction with Lenti-beta1-EGFP led to
increases in Na+,K+-ATPase holoenzyme as determined by augmentation
of sodium pump activity, and therefore supports the feasibility of
lentivirus-mediated gene transfer to augment alveolar fluid
clearance.; In vivo studies of lentiviral gene delivery to the
distal airways in 4 week old rats by non-invasive, intra-tracheal
methods led to transduction efficiencies of up to 21% at 2x108 IU.
Gene expression in vivo declined more than 5 fold between day 4 and
day 25, and was reduced to background levels at day 50. Delivery of
5x107 IU led to infection of 19.6% macrophages, 3.4% AT1 cells and
3.5% AT2 cells suggesting that macrophages were more susceptible to
viral infection. However, pulmonary macrophages represent a minor
population of airway cells. We furthermore transduced rats
intra-tracheally with
lentivirus expressing mIL-4 and were able to
detect expression in blood plasma (440 pg mIL-4/ml) for up to 28
days before levels were no longer significant.

STRATEGIES FOR TARGETING LENTIVIRAL VECTORS.

▼ Lentiviral gene therapy has held great promise for treating a wide range of neurological disorders due to its ability to stably integrate into the genome of nondividing cells like neurons, in addition to dividing cells. The nervous system is a complex and highly heterogeneous system, and while a therapeutic intervention may have beneficial effects in one population of cells it may have severe side effects in another. For this reason, specific targeting of lentiviral vectors is crucial for their ultimate utility for research and clinical research use.
Two different approaches for focusing the targeting of lentiviral vectors were employed in these studies. The first method involved assessing the effects of vector production strategies on the resulting virus’s tropism both in vivo and in vitro. The changes in vector transduction were determined via flow cytometry on cells in culture and immunohistochemistry following brain injections. Results from these experiments suggest that while the production conditions do impact the vectors efficacy, there is not a distinct effect on their tropism.
A unique characteristic of retroviral and lentiviral vectors is their capacity for being pseudotyped, conferring a new tropism on the vector. Native tropisms are generally not specific beyond very broad cell types, which may not be sufficient for all applications. In this case, chimeric targeting molecules can provide an even more refined targeting profile compared to native pseudotypes.
The second approach utilizes novel chimeric glycoproteins made from nerve growth factor and the vesicular stomatitis virus glycoprotein. These chimeras are designed to pseudotype lentiviral vectors to target nociceptive sensory neurons for a variety of disorders. While these chimeras were successfully produced as protein, they were misfolded and sequestered in the endoplasmic reticulum and therefore unavailable to produce lentivirus.
While neither strategy was completely successful, they do provide interesting information for the design and creation of lentiviral vectors. This research shows that small differences in the steps followed as part of a lentivirus production protocol can greatly impact the resulting vectors efficacy. It also shows that while VSV has been used to create chimeric glycoproteins, not all targeting molecules are suitable for this purpose.

▼ Le tabac est consommé par environ un milliard de personnes. D'après l'Organisation Mondiale de la Santé, le tabagisme est la première cause évitable de mortalité dans le monde, provocant six millions de morts par an. La nicotine est le composant neuro-actif principal dans le tabac, et exerce ses effets neurologiques via une activation directe des récepteurs nicotiniques de l’acétylcholine (nAChR). Ces récepteurs transmembranaires sont composés de sous-unités alpha, ou alpha plus beta, créant une variété de canaux ioniques ligand-dépendants activés par le neurotransmetteur ACh. Les études génétiques chez l’homme ont mis en évidence des variants dans le cluster génomique CHRNA5-CHRNA3-CHRNB4, codant pour les sous-unités α5, α3 et β4, comme facteurs influençant le tabagisme. Cette thèse a étudié le rôle des nAChRs contenant la sous-unité β4 (β4*) dans l’addiction à la nicotine. En collaboration, nous avons montré que les souris déficientes pour la sous-unité β4 (β4 KO), sont moins sensibles aux effets récompensant et aversifs de la nicotine. En générant un lentivirus exprimant la séquence murine d'ADN complémentaire de β4, j’ai pu restaurer son expression dans des régions d’intérêt du cerveau, sur un fond génétique β4KO. Ceci a permis de mettre en évidence le rôle du réseau habénulo-interpedonculaire dans la contribution des β4* nAChRs à la consommation de nicotine. Ceci a également démontré le rôle modulateur de ces récepteurs dans les réponses de la voie mésolimbique à la nicotine, voie centrale dans l'effet renforçant des drogues.
Tobacco is consumed by an estimated 1 billion people world-wide. The World Health Organization names tobacco consumption the primary cause of preventable morbidity and mortality, causing six million deaths per year. Nicotine is the principal neuro-active compound in tobacco, and exerts neurological effects by binding to nicotinic acetylcholine receptors (nAChRs). These transmembrane receptors are composed of alpha or alpha plus beta subunits, forming a diverse variety of ligand-gated ion channels endogenously activated by ACh. Human genetic studies have highlighted variants in the CHRNA5-CHRNA3-CHRNB4 genomic cluster, coding for subunits α5, α3 and β4, as altering smoking behaviours. The present thesis investigated the role of β4-containing (β4*) nAChRs in nicotine addiction. In collaboration, we showed that β4 knockout (KO) mice are less sensitive to nicotine reward and nicotine aversion. Generating a lentivirus for the expression of mouse β4 nAChR subunit complementary DNA, I was able to restore receptor expression to brain regions of interest on a KO background, locating the role of β4* nAChR in nicotine reward and aversion to the habenulo-interpedunular pathway. This also demonstrated the receptor’s modulation of nicotinic responses of the mesolimbic system, central hub of drug reinforcement.
