▼ Au cours de ma thèse, j’ai travaillé sur deux sujets complémentaires. Le premier a concerné l’étude des interactions entre les cellules tumorales et leur microenvironnement, dans quatre modèles de mésothéliomes malins (MM) de rat. Les analyses histologiques du stroma, associées à des analyses protéomiques et de l’expression de différentes cytokines/chimiokines ont permis d’identifier trois stades d’invasivité croissante, associés à des modifications quantitatives de nombreuses protéines et à un infiltrat immunitaire décroissant. La tumeur la plus invasive a été caractérisée par une immunosuppression avec un profil moléculaire spécifique augmentant le potentiel métastatique. Le second sujet a concerné l’évaluation de l’efficacité de la virothérapie anti-tumorale, basée sur l’utilisation de la souche vaccinale du virus de la rougeole MV et de son variant MV-ΔC, pour le traitement du MM. Les deux virus ont induit des régressions tumorales chez des souris NOD SCID transplantées avec deux lignées de MM humains, le MV-ΔC amplifiant cet effet en induisant une mort cellulaire plus rapide, attestée par une réduction plus marquée de la masse tumorale. Ce potentiel apoptotique est associé, in vitro, à une production accrue du signal de danger HMGB1 et à la synthèse d’une grande quantité d’ARN double brin viral. Ces cellules infectées par le MV-ΔC sont aussi capables de favoriser la maturation des cellules dendritiques grâce à la réplication virale et à l’activation de Protéine Kinase R. Ce travail de caractérisation de nouveaux modèles immunocompétents et de nouvelles stratégies thérapeutiques permet d'envisager un meilleur traitement des patients souffrant de mésothéliome.
As a PhD student, I worked in parallel on two complementary subjects. The first one concerned the study of the interactions between tumor cells and their microenvironment in four models of rat malignant mesothelioma (MM), differing in both their immune infiltrate and their metastatic potential. Histological analyses of stroma, together with proteomic analyses and expression of different cytokines, chemokines and growth factors, led us to the identification of three stages of increasing invasiveness, associated with quantitative changes in many proteins and a decreased immune infiltrate. The most invasive tumor was characterized by immunosuppression with a specific molecular profile increasing the metastatic potential. The second topic was the evaluation of the efficacy of anti-tumor virotherapy, based on the use of the Schwarz strain of measles virus (MV) and its variant MV-ΔC for the treatment of MM. Both viruses induced tumor regressions in NOD SCID mice transplanted with two human MM cell lines, but MV-ΔC amplified this effect by inducing faster cell death, as revealed by a marked reduction of the tumor mass. This apoptotic potential is associated, in vitro, with an increased production of the danger signal HMGB1 and the synthesis of a large amount of viral double-stranded RNA. These MV-ΔC-infected cells are also capable of promoting the maturation of…

Image-Based Analysis of Thumb Carpometacarpal Joint
Biomechanics in Health and Early Osteoarthritis.

▼ Humans have a unique opposable thumb that maintains a
fine balance between mobility and stability to allow motions that
span from precision handling to power grasping. Much of the
versatility of the thumb is due to the saddle geometry of first
carpometacarpal (CMC) joint. Located at the base of the thumb, the
CMC joint is the most common site of reconstructive surgery in the
upper extremity. Nearly 40% of postmenopausal women are affected by
CMC osteoarthritis (OA)—a progressive degenerative disease of
articular cartilage, bone, and synovium that results in decreased
dexterity and partial impairment of the upper extremity. Although
current treatment options can alleviate pain, they cannot restore
the lost strength and mobility, or halt disease progression,
because the pathophysiology of the disease is poorly understood.
While both biological and mechanical factors are implicated in the
etiology of CMC OA, the synergistic mechanism of disease evolution
remains unclear, partially due to a paucity of published data on
CMC joint biomechanics in healthy and diseased populations.
Accordingly, the objective of this work was to study CMC joint
biomechanics using in
vivo image-based techniques, and to determine
if there are any differences with sex, age, or OA onset that could
point to the etiology of the disease. 155 subjects—healthy men and
women of two age groups and patients with early stage CMC OA—were
recruited for the study. Sequential computed tomography scans of
the hands and wrists of all the participants were acquired while
they performed functional tasks and range-of-motion activities. The
imaging data were used to study joint motion, stability, contact
mechanics, articular shape and congruence, as well as to model soft
tissue: cartilage and ligaments. The findings presented here
suggest that there may not be a mechanical predisposition to CMC
OA, but that women may be more susceptible to cartilage loss due to
systemic changes with aging. In addition to channeling future
research in the right direction, the furthered understanding of CMC
joint biomechanics should serve to refine the current surgical
procedures and to inspire new conservative options for disease
treatment and prevention.

▼ Many human diseases are diagnosed by the histopathological analysis of suspicious lesions where cellular morphological changes are examined at microscopic resolution. Reflectance confocal microscopy (RCM) and optical coherence tomography (OCT) are two optical imaging technologies that can visualize microscopic details of the tissue without having to remove or process the tissue. However, both RCM and OCT are generally expensive and have either limited field of view or low resolution. Light sheet microscopy, an imaging modality utilizing a thin sheet of light for illumination, can achieve comparable resolution compared to RCM while providing a field of view comparable to OCT. The light sheet microscope can be made at low cost by using a consumer-grade CMOS camera, an inexpensive light source such as an LED, and low-NA objective lenses. In this thesis, we have developed two simple light sheet microscopes with a goal of rapidly visualizing cellular details of the intact tissue either in
vivo or ex
vivo. The first utilized near-infrared illumination and the second utilized visible illumination. Preliminary imaging results showed that cellular details of the tissue can be visualized over a large field of view in both animal and human tissues.

▼ The objective of the current research project relies on implementation of solvent-free, green and environmentally friendly solid phase microextraction (SPME) sample preparation alternative in the area of complex sample characterization. The advantages that the technique offers in comparison to traditional methods of sample preparation including solvent-free implementation, short sample preparation times, small sample amount requirements, advanced automation capability and minimization of matrix effects are effectively employed during ex vivo and laboratory investigations of complex samples. More important, the underlying features of the technique including miniaturized format, nonexhaustive extraction recoveries and on-site compatibility were fully exploited in order to investigate the metabolome of biological systems directly on the site. Hence, in vivo SPME extraction format was employed in direct immersion SPME sampling of biological systems, hence eliminating the crucial prerequisites associated with multiple preparative steps and incorporation of metabolism quenching that are encountered during implementation of traditional sample preparation methods in global metabolite analysis. Furthermore, in vivo sampling format was hyphenated to comprehensive two-dimensional gas chromatography – time-of-flight mass spectrometry (GCxGC-ToFMS) for high-resolution sampling of volatile and semivolatile metabolites in ‘Honeycrisp’ apples.
The initial stages of the project involved evaluation of performance characteristics of commercial SPME extraction coatings in terms of extraction selectivity, extraction sensitivity and desorption efficiency by employing headspace SPME analysis of both aqueous standards spiked with representative volatile and semivolatile metabolites as well as the apple homogenate. DVB/CAR/PDMS coating was selected on the basis of optimum metabolite coverage and extraction sensitivity and was consequently employed during ex vivo and in vivo sampling assays corresponding to determination of volatile and semivolatile metabolites. The former extraction methodology incorporated appropriate sample preparation steps for quenching metabolic activity so that the relevant metabolome profile is not biased against unstable metabolites and those that are susceptible to inter-metabolite conversions which adversely impact preservation of metabolite identity. The two sample preparation assays were compared in terms of metabolite coverage and analytical precision in order to identify SPME route toward characterization of more representative metabolome and determination of instantaneous and more ‘true’ metabolism snapshoot. This is the first report illustrating the implementation of in vivo direct immersion SPME assay for non invasive determination of endogenous fruit metabolites whose profiles and contents are highly correlated to a multitude of influential fruit quality traits.

▼ Introduction: In order to maintain uniform standards in the accuracy of fractionated radiation therapy, quantification of the delivered dose per fraction accuracy is required. The pupose of this study was to investigate the feasibility of a transit dosimetry method using the electronic portal imaging device (EPID) for dose delivery error detection and prevention. Methods and Materials: In the proposed method, 2D predicted transit images were generated for comparison with online images acquired during treatment. Predicted transit images were generated by convolving through-air EPID measurements of each field with pixel-specific kernels selected from a library of pre-calculated Monte Carlo pencil kernels of various radiological thicknesses. The kernel used for each pixel was selected based on the calculated radiological thickness of the patient along the line joining the pixel to the virtual source. The accuracy of the technique was evaluated in homogeneous plastic water phantoms, a heterogeneous cylindrical phantom, and an anthropomorphic head phantom. Gamma analysis was used to quantify the accuracy of the technique for the various cases. Results: In the comparison between the measured and predicted images, an average of 99.4% of the points in passed a 3%/ 3 mm gamma for the homogeneous plastic water phantoms. Points for the heterogeneous cylindrical phantom analysis had a 94.6% passing rate. For the anthropomorphic head phantom, an average of 98.3% and 96.6% of points passed the 5%/3mm and 3%/3mm gamma criteria, respectively for all field sizes. Failures occurred typically at points when object thickness was changing rapidly or at boundaries between materials, and at the edges of large fields. Discussion: The results suggested that the proposed transit dosimetry method is a feasible approach to in vivo dose monitoring. The gamma analysis passing rates are within the accuracy needed for transit dosimetry. Future research efforts should include evaluation of the method for more complex treatment techniques and assessment of the sensitivity to changes in EPID or linac hardware, as well as characterization of any dependency the method may have on image ghosting or lag, gantry angle, or long-term stability.

▼ L'expression des trois protéines de neurofilaments (NF) NFL, NFM et NFH ainsi que I'a-intemexine et la périphérine a été déterminée par immunobuvardage "Western" durant Ie développement de neurones embryonnaires de ganglions dorsaux en culture. Au jour 0 de la culture, les neurones contenaient surtout de I'a-intemexine. La quantité de périphérine a augmenté de façon significative après 1-2 jours en culture, celle de NFL et NFM après 2-3 jours, et celle de NFH après 5-6 jours. L'analyse des cultures par immunofluorescence indirecte a révélé que les cinq protéines de filament intermédiaire neuronaux (Fin) étaient co-Iocalisées dans tout les compartiments des neurones. L'analyse d'extraits cellulaires solubles au Triton X-100 suite à un traitement a I'acide okadaïque a indiqué que la solubilisation de I'a-intemexine et de la périphérine suivaient Ie même profile que pour NFL, NFM et NFH. L'incubation de ces extraits cellulaires avec des anticorps spécifiques pour chaque protéine permit la co-immunoprécipitation de NFH avec NFL, NFM avec NFL, NFM avec a-internexine et a-internexine avec peripherine démontrant ainsi que ces cinq protéines sont associées dans Ie réseau de Fin des neurones sensorielles en culture.
The developmental profile of the neurofilament (NF) triplet proteins, a-internexin and peripherin in cultured embryonal dorsal root ganglion neurons was determined by Western blot analysis. At day 0 in culture, the neurons contained mostly a-internexin. A significant increase in peripherin levels was seen at days 1-2, in the mid-sized (NFM) and low molecular weight (NFL) NF subunits at days 2-3, and in the high molecular weight (NFH) NF subunit at days 5-6. Immunofluorescence microscopy showed that the five neuronal intermediate filament (nlF) proteins were colocalized in all neuronal cell bodies and neurites. Analysis of Triton X-100-soluble extracts from okadaic acid-treated DRG cultures revealed that peripherin and a-internexin followed the same fragmentation pattern observed for NFs. When these extracts were incubated with antibodies specific for the individual proteins, coimmunoprecipitation of NFH with NFL, NFM with NFL, NFM with a-internexin, and a-internexin with peripherin were observed, demonstrating that nlF proteins in cultured sensory neurons form a highly integrated network.

▼ Ferrochelatase is the terminal enzyme in the heme biosynthetic pathway and catalyzes the insertion of ferrous iron into protoporphyrin IX in the formation of protoheme IX. Little is known about how substrate iron is acquired and taken up by
the enzyme or how the enzyme functions at the cellular level. Here we investigated the putative roles of several amino acid residues in vivo by constructing and analyzing site-directed mutants within the C-terminus, on the protein surface, and inside the
active site of human ferrochelatase. In vivo function of the enzyme was assessed by monitoring complementation, cellular growth rates and heme production in a ferrochelatase-deficient strain of Saccharomyces cerevisiae. The data suggest a possible
surface site that may be involved in ferrochelatase function. These initial in vivo characterizations may lead to future advances in identifying specific amino acid residues that play a role in ferrochelatase function.

▼ Porous silicon (PSi) photonic crystals have aroused interest as chemical and biological sensing devices and have been used as label-free optical biosensors in recent years. The advantage of using PSi as a sensor comes from the ease of fabrication and high quality optics. The recent advances in modifying the surface of these porous materials with different surface chemistries have been utilized to add stability to the otherwise unstable freshly etched PSi surface. The results presented in this thesis have been obtained while developing porous silicon microsensors for their use in detecting protease enzyme activity in
vivo. The research presented here primarily focuses on the additions made to the surface modification strategies to add functionalities to the surface for specific target (enzyme) detection and quantification both in vitro and in
vivo. A specific class of photonic crystals, rugate filters were fabricated on p-type silicon and used as transducers to transform biological changes to easily read-out optical signals. The presence of a high reflectivity resonant stop-band in the reflectance spectra of these filters made them an ideal choice to be used as a transducing element thereby adding sensitivity to the biosensor. A chemical route based on hydrosilylation of alkynes was adopted to modify the freshly etched PSi surface. This was followed by the copper (I) - catalysed azide cycloaddition reaction using a synthetic anti-fouling polymer to resist non-specific adsorption of biomolecules. Immobilisation of enzyme responsive peptides to these organic layers added specificity to the PSi structure. This specificity was demonstrated by the selective detection of matrix metalloproteases (MMP), MMP-2 and MMP-9 enzymes released from different primary ocular cells by measuring optical blue shifts of these PSi rugate filters. Detection of pg quantities of these MMPs was achieved using these microsensors. The sensitivity achieved by the PSi microsensors was lower than that achieved with zymography; the standard protease detection technique. This functionalisation of the surface with peptides adds versatility to the surface and allows for a range of other biological species to be detected for applications in biology and medicine. Towards protease detection in
vivo, PSi microparticles were injected into eyes of live rabbit animal models. The microparticles were shown to be biocompatible for up to 4 weeks. The animal models were injected with a bacterial endotoxin, lipopolysaccharide to cause endotoxin induced uveitis (EIU) with associated up regulation of the release of proteases inside the eye. Efforts were made to detect the release of MMP-9 in
vivo by the injected PSi microparticles by measuring optical changes in the reflectivity spectra of these particles in real time. Digestion of the peptide was detected down to 1.3 picomoles (11.7 nM) of the protease in the uveitis infected eye. The detection of proteases both in vitro and in
vivo via the use of robust, selective and flexible surface chemistry on PSi photonic…

▼ Predictive pharmacokinetics now forms a critical
part of the drug discovery process. However, metabolic data has
been demonstrated to under-predict in
vivo clearance, while no
large scale analysis has been performed for hepatic uptake data.
The primary aim of this thesis was therefore to investigate the
utility of various clearance parameters generated in hepatocellular
assays for the prediction of in
vivo clearance. Large scale
literature analyses were performed for uptake data in both rat and
human hepatocytes. In the rat, it was highlighted that
over-prediction was the predominant issue for suspension and media
loss hepatocyte assays. Conversely, monolayer and SCH assays
suffered from under-prediction. However, in human hepatocytes
under-prediction was observed in all assay formats. Use of
empirical scaling factors improved predictions in both species, and
are recommended for future use. The media loss assay, a method
described by Soars et al[1], was further developed in rat
hepatocytes through inclusion of transporter and metabolic enzyme
inhibitors. Using a two-compartment model, individual clearance
parameters (CLmet, CLactive and CLpassive) were estimated, and were
also used to estimate binding and partitioning terms (Kp, Kpu and
fucell). IVIVE of data produced from this assay resulted in a lower
bias than had been noted from literature data. However, it was
hypothesised that additional clearance parameters could be used in
a mechanistic approach to further improve predictions. SCH assays
were performed to generate estimates of uptake rates, as well as
efflux rates from both the sinusoidal and canalicular membranes.
Combining clearance terms from both the media loss and SCH assays
using the CLint,total term led to less bias when predicting in
vivo
clearance than observed using uptake or metabolism data alone.
Additionally, the use of empirical scaling factors identified from
the literature analysis led to further reduction in prediction
bias. Future work must now focus on the application of this
research to human hepatocytes. It is concluded that the work
presented in this thesis provides evidence for the usefulness of
both uptake and extended clearance terms, in conjunction with
empirical scaling methods, for the prediction of in
vivo clearance.
Adaptation of the media loss assay allowed the estimation of
several key pharmacokinetic parameters. Although some of these are
not always useful in a quantitative fashion, they remain essential
properties of a compound that must be considered when predicting
behaviour within the body.

▼ Les processus de neuro-inflammation jouent un rôle majeur dans la maladie d'Alzheimer (MA). Des études génétiques récentes démontrent cette association entre neuro-inflammation et MA et impliquent notamment un gène, TREM2, qui code pour un récepteur exprimé à la surface de la microglie. La tauopathie est une lésion caractéristique de la MA. Elle se traduit par l’hyperphosphorylation et l’agrégation intraneuronale de la protéine Tau. Les travaux sur le rôle de TREM2 dans le développement de la pathologie Tau sont peu nombreux et donnent des résultats contradictoiresAinsi, l’objectif de ma thèse est d’étudier le rôle de la neuroinflammation et de TREM2 dans la progression de la tauopathie, dans deux modèles différents. Le premier est obtenu par injection stéréotaxique de vecteurs AAV dans la couche CA1 de l’hippocampe de souris déficientes ou non en TREM2. Ces vecteurs entrainent la surexpression de différentes formes de la protéine Tau humaine et permettent de récapituler les différents stades de la tauopathie.Nous avons en parallèle utilisé un modèle transgénique plus progressif de tauopathie, la souris THY-Tau22, afin d’étudier l’influence du stade de la pathologie dans l’effet provoqué par une déficience en TREM2 sur l’évolution de la pathologie. Notre étude a mis en évidence la toxicité des formes solubles de Tau dans le modèle AAV par rapport à ses formes agrégées. Le modèle transgénique THY-Tau22 nous a permis de mettre en évidence une augmentation des lésions tauopathiques dans les souris déficientes en TREM2 par rapport aux souris qui ne le sont pas, uniquement à un stade avancé. Cela suggère que, à l’instar des modèles amyloïdes, l’effet de la déficience en TREM2 sur le décours de la tauopathie est différent en fonction du stade considéré.
Neuroinflammation processes appear to play a major role in Alzheimer's disease (AD). Recent genetic studies support this correlation between neuroinflammation and AD and include a gene, TREM2, expressed on microglial surface. Tauopathy is a characteristic lesion of AD. It results in hyperphosphorylation and intraneuronal aggregation of Tau protein. In the literature, only few articles describe the role of TREM2 in the development of Tau pathology, and they report contradictory results. We therefore do not know for sure whether a deficiency in TREM2 has a deleterious effect or not on tauopathy. Thus, the goal of my thesis is to study the role of neuroinflammation and TREM2 in the progression of tauopathy, in two different models. The first is obtained by stereotaxic injection of AAV vectors into the CA1 layer of the hippocampus of TREM2-deficient or non-deficient mice. These vectors lead to the overexpression of different forms of the human tau protein, thus making it possible to recapitulate the different tauopathy stages.In parallel, we used a more progressive trangenic model of tauopathy, the THY-Tau22 mouse, to study the influence of TREM2 deficiency at different stage of the pathology. Our study demonstrated the toxicity of Tau soluble forms in the AAV model compared…

▼ Skóra stanowi bardzo dobry model badawczy w odniesieniu do całościowego zjawiska starzenia. Jest ona bezpośrednio narażona na destrukcyjne działanie czynników zewnętrznych. Ulega starzeniu szybciej niż pozostałe narządy naszego ciała. Poznanie mechanizmów starzenia się pozwala nam zrozumieć, w jaki sposób musimy zapobiegać i przeciwdziałać temu procesowi. Jest to proces wieloczynnikowy, regulowany przez czynniki genetyczne, jak i środowiskowe. W rozprawie doktorskiej zaprezentowano zagadnienia literaturowe m.in. z zakresu chemii kosmetycznej. Przegląd literatury rozpoczęto od budowy skóry. Dokonano przeglądu karotenoidów. W kolejnych rozdziałach opisano metody: badania in
vivo formulacji kosmetycznych, oceny stabilności emulsji kosmetycznych, określania składu form kosmetycznych oraz badania biodostępności z wykorzystaniem metody zdzierania oraz kinetyki uwalniania substancji aktywnych z formulacji kosmetycznych. W części doświadczalnej zaprojektowano oraz otrzymano formulacje kosmetyczne o określonym, pożądanym przeciwutleniającym spektrum działania. Podsumowując, w ramach pracy doktorskiej opracowano nowe receptury formulacji kosmetycznych z wybranymi karotenoidami oraz przeprowadzono badania in
vivo na probantach z wykorzystaniem samodzielnie przygotowanych emulsji kosmetycznych zawierających β-karoten. Testy aplikacyjne potwierdziły poprawę poziomu nawilżenia, elastyczności skóry oraz natłuszczenia skóry ochotników. Na podstawie badań wyciągnięto wniosek, że opracowany kosmetyk poprawia ogólną kondycję skóry. Wykazano za pomocą badania biodostępności β-karotenu metodą zdzierania, że karotenoid ten przenika do górnej warstwy naskórka - stratum corneum.

▼ Research Doctorate - PhD (Food Science)
Folic acid has been the focus of extensive research since it plays an essential role in the human body as a major coenzyme in one-carbon metabolism. This metabolic role facilitates both methionine and DNA synthesis. It has been suggested that increased folate intake, and hence blood status, provides benefits in maintaining health. However, a growing body of literature now reports differing opinions with respect to the level of folic acid intake, the type of vitamer and pathoaetiological outcomes. Part of this controversy lies in the study of cancer aetiology, particularly in the context of adenomatous polyp (AP) occurrence. AP is an antecedent of colorectal cancer. As part of the present study an in vivo model was therefore developed in order to re-examine the role of folate in carcinogenesis, taking into account both genetic variants and environmental factors. To obtain further evidence, the biological characteristics of folate vitamers in promoting cancer cell proliferation were examined using an in vitro model. 202 individuals were recruited and placed into two groups depending upon whether they had been diagnosed with AP or were control subjects. The blood folate, thiol levels, dietary folate intake, including synthetic and natural forms, and intake of nutrients related to one-carbon metabolism (pyridoxine, riboflavin, cobalamin, niacin, methionine and vitamin C) of each subject were evaluated. Sixteen major genetic variants in folate metabolism were also determined as potential risk factors in AP aetiology: MTHFR C677T, A1208C, G1793A, SHMT C1420T, TS 1496del6, TSER 2R3R, TS 3RG>C, GCPII C1561T, CBS 844ins66, DHFR 19bp del , RCF G80A, CTH G1364T, IVS 10-430 C>T, BHMT G595A, MS A2756G and MSR A66G. Statistical analysis has provided evidence to suggest that AP aetiology depends upon a range of interactions between genes and nutrition. The following factors were found to be associated with an increased risk of developing AP: RBC folate level (p for females = 0.0021 and males = 0.004), nutritional intake (p for methylfolate intake below the median = 0.0189 and cobalamin intake above median = 0.0402) and genetic variants (p for CBS 844ins68 = 0.035, TS 1496del6 = 0.048, MSR A66G = 0.025 and MTHFR C677T- CBS 844ins66 = 0.0403). Although no direct correlation was found between PteGlu intake and the occurrence of AP, genetic variants predicted a differential AP risk depending on total dietary folate intake level (in subjects with total dietary folate intake above the RDI: p for MTHFR A1298C= 0.026, MTHFR C677T-A1298C-G1793A=0.016, TS 1496del6 = 0.024, DHFR 19bp del = 0.032, and, in subjects with total dietary folate intake below the RDI: MTHFR A1298C2= 0.011, RFC G80A-GCPII C1561T3= 0.033). Additionally, vitamin C was also associated with occurrence of AP when examined by RCF G80A and GCPII C1561T genotype (p for RFC G80A AA = 0.0473, GCP II C1561T CT= 0.0276 and RFC G80A-GCPII C1561T AA/CC = 0.0026).

▼ Der Hippocampus spielt eine wichtige Rolle bei der
Bildung von Gedächtnis. Die vorliegende Studie dient zur Klärung
der Frage nach der synaptischen Änderung, die sich auf
elektrophysiolgischer Ebene in Bezug auf object recognition in frei
beweglichen Mäusen vollzieht. Jede Maus wurde chronisch implantiert
mit einer Ableitelektrode in der CA1 und einer
Stimulationselektrode in der Schafferkollateralen. Hier konnte
gezeigt werden, dass object recognition LTD an CA1 Synapsen
auslöst. Änderungen in object-space scheint hierbei eher die
synaptische Antwort auszulösen als Änderungen der Objekte an sich.
Das erfolgreiche Erkennen der beschriebenen Änderungen ist sowohl
abhängig von NMDA also auch von mGlu5 Rezeptoren. Demnach ist die
räumliche Anordnung eine Komponente der object recognition. Hierbei
gilt als neu jegliche Änderungen, sowohl in space als auch in
object und facilitiert LTD in CA1.

▼ Das kolorektale Adenom gilt als Vorläuferläsion des
kolorektalen Karzinoms, wobei die Dysregulation des APC/β-
catenin-Signalweges in der Adenom-Karzinom-Sequenz ein frühes
Schlüsselereignis ist. Ziel dieser Arbeit war es, den Einfluss von
5-Aminosalicylsäure (5-ASA) in
vivo am Polypengewebe der German
5-ASA polyp prevention study auf den APC/β-catenin-Signalweg und
damit Auswirkungen auf die Adenomprogression zu untersuchen.
Mittels Immunhistochemie wurde die Expression von β-catenin,
E-cadherin, Cyclin D1, Cox-2 und p53 vor und nach Medikation mit
5-ASA bestimmt und statistisch ausgewertet. Es ließ sich eine
signifikante Reduktion der Expression von β-catenin, E-cadherin,
Cyclin D1, Cox-2 und p53 der 5-ASA- Gruppe im Vergleich mit der
Placebo-Gruppe nachweisen. In
vivo zeigte sich nach einer
Behandlung mit 5-ASA in sporadischen kolorektalen Adenomen ein
Einfluss auf den APC/β- catenin-Signalweg und damit möglicherweise
eine Verlangsamung der Adenomprogression.

▼ Synaptische Plastizität gilt als Mechanismus, der
Lern- und Gedächtnisvorgängen zugrunde liegt. Dabei spielt auf
molekularer Ebene der NMDA-Rezeptor, besonders an den
Schaffer-Kollateralen-CA1-Synapsen, eine große Rolle. Diese Arbeit
zeigt NMDA-Rezeptor abhängige synaptischer Plastizität an der
wachen Maus. Präziser wurde mithilfe von GluN2A-defizienten Mäusen
verdeutlicht, dass GluN2A- und GluN2B-Untereinheiten für
bidirektionale Plastizität wichtig sind. Die Involvierung von GluN2
ist vom Stimulus abhängig. Zusätzlich konnte gezeigt werden, dass
in der murinen CA1-Region unterschwellige elektrische Reizung,
gepaart räumlichen Reizen, zu robuster synaptischer Plastizität
führt. Komplexe Stimuli im "Environmental Enrichment" verstärkten
STP in jungen und gealterten Mäusen. Dieser Effekt hielt jedoch
etwa 3 Tage nach zweiwöchigen Enrichment an und war nur durch
Kombination räumlicher und sozialer Stimuli zu beobachten. Es
handelte sich um einen mGlu5- und GluN2A-abhängigen
Mechanismus.

▼ A esquistossomose é uma doença parasitária crônica das regiões tropicais e
subtropicais e está associada a uma alta morbidade da população infectada. A
terapia da esquistossomose é feita apenas com um único fármaco, o
praziquantel, ativo contra todas as espécies de Schistosoma, e o oxamniquina
ativo apenas contra o Schistosoma mansoni. Contudo há relatos na literatura
de resistência do parasito ao tratamento para os dois fármacos, gerando uma
preocupação a nível mundial e levando a Organização Mundial de Saúde
(OMS) convocar a indústria e os pesquisadores a buscar novos fármacos com
esta finalidade. Neste contexto a busca de novos fármacos com atividade
esquistossomicida torna-se o objetivo deste trabalho, onde os derivados
imidazolidínicos das séries 5-benzilideno-3-benzil-4-tioxo-imidazolidin-2-ona
(LPSF/PT), 5-benzilideno-3-(4-metil-benzil)-imidazolidina-2,4-diona (LPSF/MS)
e 5-arilazo-4-tioxo-imidazolidin-2-ona (LPSF/PT) foram avaliados in vitro frente
a vermes adultos de Schistosoma mansoni (Cepa BH). Dos derivados
avaliados in vitro os que apresentaram atividade esquistossomicida, foram os
derivados da série 3-benzil-5-(arilazo)-4-tioxo-imidazolidin-2-ona (LPSF/PT).
Para a avaliação in
vivo, o derivado 3-benzil-5-(4-cloro-arilazo)-4-tioxoimidazolidin-
2-ona (LPSF/PT05) foi administrado oralmente em Tween 80,
Tween/óleo/água e em dispersão sólida com 90 % PEG (Polietilenoglicol).
Apenas esta última apresentou efeito esquistossomicida. Foram administradas
quatro doses: 3, 10, 30 e 100 mg/kg. A redução do número de vermes
recuperados foi significativa para a dose de 10 e 30 mg/kg, aproximadamente
50 % e para a dose de 100 mg/kg a redução foi de 68%. A redução do número
de vermes na dose de 100 mg/kg corroborou com a resposta imune celular do
derivado e levantou a hipótese do seu efeito imunossupressor ser ao nível de
resposta Th1 e Th2. Somado a esses dados a resposta histopatológica revelou
uma modulação na resposta granulomatosa, produziu uma ação contra o dano
hepático causado pela infecção pelo S. mansoni

▼ Apesar da introdução do controle da qualidade individual nas técnicas complexas de tratamentos, tem-se comprovado que, mesmo assim, é possível a ocorrência de erros na aplicação da dose no momento da aplicação. No entanto, ainda não estão bem estabelecidas as ferramentas de redundância a fim de controlar a dose no momento da terapêutica, além do que, as técnicas mais modernas de tratamento radioterápico desenvolvem as aplicações com feixes rotacionais e os dosímetros tradicionalmente utilizados em controle da qualidade oferecem limitações angulares. Assim, este trabalho vem contribuir para o desenvolvimento de uma metodologia de controle da qualidade de transmissão in vivo utilizando filmes radiocrômicos acoplados ao cabeçote do acelerador linear, durante aplicações radioterápicas nas técnicas de tratamento conformacional e IMRT. A metodologia de controle da qualidade desenvolvida neste trabalho baseia-se na obtenção da distribuição de dose in vivo de tratamentos radioterápicos com um filme radiocrômico EBT2 posicionado em um suporte acrílico, semelhante a uma bandeja, a uma distância fonte-superfície de 56,8 cm, acoplado ao acessório holder do acelerador linear durante a aplicação de todo o tratamento teleterápico. Posteriormente, foi realizada uma análise gama para comparação da distribuição de dose medida pelo filme com a esperada pelo sistema de planejamento, obtida no plano coronal e central de um objeto simulador, com dimensões semelhantes ao suporte acrílico, posicionado à distância de 100 cm, como resultado da transferência do plano em questão. Com os resultados encontrados na seção conformacional, avaliando tanto a simulação Monte Carlo quanto as irradiações, pode-se concluir que a diferença entre a distribuição de dose do sistema de planejamento, na distância foco detector de 100 cm, e do filme, na distância de 56,8 cm, é diminuta e, desta forma, é viável criar uma metodologia para verificação dosimétrica de transmissão utilizando o filme radiocrômico acoplado ao cabeçote do acelerador. O controle da qualidade proposto na técnica de IMRT concordou com o esperado em 24 das 25 situações testadas, apresentando apenas um resultado diferente, ou seja, uma concordância de 96% com o esperado. As avaliações in vivo concordaram com 98% dos controles avaliados. Desta forma, pode-se concluir que a metodologia proposta neste trabalho é factível para o controle da qualidade de transmissão in vivo, em tratamentos radioterápicos que usam a técnica de tratamento conformacional e IMRT e, como ela não oferece dificuldades para o deslocamento angular do gantry, ela poderá ser aplicada em técnicas teleterápicas mais modernas.
Even with the introduction of the individual quality control in the complex techniques of radiation therapy treatments, the occurrence of errors in the release of the dose at the time of application is possible. However, in order to monitor the dose at the time of therapy, redundancy tools are not yet well established, Besides that, the most modern techniques of radiation treatment use rotational beams…

▼ The formation of functional blood vessels in engineered or ischemic tissues remains a significant scientific and clinical hurdle. Cell delivery, scaffold design, and growth factor delivery have been investigated to support neovascularization. This thesis focuses on a hybrid approach wherein cells are seeded within a biosynthetic scaffold. Our approach is motivated by the relatively poor performance of cells alone; cell engraftment is minimal (10%) in scaffold-free approaches. Natural and synthetic materials have been utilized to improve engraftment, but the biosynthetic scaffold presented here offers unique advantages to overcome limitations of natural materials and offers tunability of matrix properties and biological response.
A PEG hydrogel platform was adapted to investigate the roles of network crosslinking density and susceptibility to proteolysis on vascularization. Four-arm PEG vinyl sulfone (PEGVS) was polymerized by Michael-type addition with reactive cysteine groups on a slowly degraded matrix metalloprotease (MMP) susceptible peptide, GPQG↓IWGQ, or a peptide that is cleaved more rapidly, VPMS↓MRGG. Vascular networks formed in vitro from encapsulated endothelial cells and supportive stromal fibroblasts. Morphogenesis was robust to changes in cross-linking peptide identity, but significantly attenuated in more crosslinked gels. All gel types supported the de novo formation of perfused vasculature from transplanted cells in subcutaneous implants in
vivo; however, unlike the in vitro findings, vascularization was not decreased in the more cross-linked gels.
A mouse model of hindlimb ischemia was used to further assess the ability of PEG hydrogels to support revascularization in a model relevant for clinical translation. Cell-laden PEG hydrogel precursors and fibrin controls were delivered to SCID mice after femoral artery ligation. PEG hydrogels supported the formation of perfused vasculature irrespective of crosslinking-peptide identity. Hydrogel delivery improved reperfusion to the ischemic limb. Substantial loss of gel mechanical integrity and vessel regression were evident in fibrin gels, but not in PEG gels, 2 weeks post-implantation, suggesting PEG hydrogels are superior to fibrin with regards to vessel persistence. In sum, these findings demonstrate that structurally stable biomimetic PEG-based hydrogels direct vascularization in ischemic tissues via cell transplantation and hold promise in tissue regeneration and therapeutic angiogenesis.

▼ RNA interference (RNAi) by small interfering RNA (siRNA) possesses great promise as a therapeutic for pathologies whose etiology is related to gene overexpression. However, due to the poor pharmacokinetic properties of siRNA, it requires a carrier for in
vivo intravenous delivery. Historically, nucleic acid delivery systems have utilized cationic lipids or polymers as carriers, but such agents are poorly translatable in
vivo, as they have inadequate hemo-stability, a short blood circulation half-life, and can lead to unexpected toxicity. Here, we introduce a series of novel mixed micelles that modulate the molar concentration and lengths of poly(ethylene glycol) (PEG) on the corona of the micelles to achieve charge shielding that improves the pharmacokinetic properties of the siRNA-micelle complex, while maintain significant levels of gene knockdown. Hemocompatibility and in vitro stability is increased for micelles with greater PEG surface concentration and for micelles with higher molecular weight PEG in the corona. When delivered intravenously in
vivo, micelles with a higher molecular weight PEG in the corona demonstrate a significantly improved blood circulation half-life (17.8 minutes for micelles with a 20 kDa PEG vs. 4.6 minutes for micelles with a 5 kDa PEG) and a 4-fold decrease in lung accumulation. These improved in
vivo pharmacokinetics have the potential to be applied to leverage the enhanced permeation and retention (EPR) effect for biodistribution to and gene silencing in vascularized tumors.

▼ Breast cancer has the highest incidence rate in women, accounting for more than 22% of all cancers and possessing a strong disposition to metastasize to bone. These skeletal metastases become a significant cause of morbidity and mortality in patients with the primary symptom being pain. Pain is a major concern in determining a patient’s quality of life and there have been many attempts to understand and control bone pain with little success. Previous studies have shown that glutamate plays a role in bone cancer pain, with an excess in free glutamate able to cause pain either directly through excitotoxic pathways or indirectly though the dysregulation of osteoclasts and osteoblasts, causing bone dysregulation. TRPV-1 receptors have also has been implicated in the mechanisms of bone cancer pain, as osteoclasts release protons during bone remodeling which can elicit a TRPV-1-related nociceptive response from neurons in the surrounding periosteum. Capsazepine was identified during a high throughput screen of 30,000 compounds to be a potent inhibitor of breast cancer cell-mediated glutamate release, a neurotransmitter with known associations in neural signaling, bone homeostasis, and pain. Capsazepine also has antagonistic effects on transient receptor potential vanilloid type 1 (TRPV-1) receptors which act as key players in both heat and vanilloid-induced nociception. These findings suggest that Capsazepine may provide a multi-site effect for the treatment of cancer-induced bone pain. An animal model of breast cancer-induced bone pain involved intrafemorally injecting MDA-MB-231 cancer cells to measure pain. Behavioural tests are then performed measuring dynamic weight bearing and paw withdrawal thresholds. These measurements are used to demonstrate both movement-evoked and spontaneous pain-related behaviour of the affected limb. Using Capsazepine, we demonstrate a dose-dependent attenuation of pain behaviour in vivo, while confirming tumour presence using immunohistochemistry (IHC). We show that TRPV-1 and glutamate play an important role in the onset and severity of bone cancer pain and blocking these pain pathways provide relief from pain commonly associated with cancer in the bone.

▼ Increases in cerebral blood flow are widely used as surrogate indicators of neural activity, making the understanding of the precision and regularity of cerebral hemodynamic signals of fundamental importance. To determine whether cerebral blood flow is tightly regulated spatially and temporally, we measured hemodynamic signals in the mouse cortex during voluntary locomotion, which drives large changes in neural activity and in the peripheral cardiovascular system.
Locomotion drives the increase of neural activity in both frontal and parietal cortices in mice. Parietal cortex, especially within the forelimb and hindlimb representations, showed significant increases of blood flow and volume, supporting neurovascular coupling. But frontal cortex showed little or no hemodynamic response, suggesting a neurovascular decoupling mechanism within the region. To quantify the spatial and temporal characters of cerebral hemodynamics, we developed a novel empirical model that is based on microscopic dynamics of artery and vein dilations. This model reliably fits the cerebral hemodynamics in the parietal cortex and quantitatively separated out arterial and venous blood volume. Using this model, we showed that the cerebral hemodynamics in regions presenting neurovascular coupling are highly predictable in space and time. Further, by pharmacologically manipulating the heart rate, we separately tested the sympathetic and parasympathetic influences on the cerebral hemodynamics. We found that the cerebral arterial response and blood flow are highly robust to cardiovascular perturbations; but venous blood volume changes were largely compromised by adrenergic blockade. We concluded that neurovascular coupling during voluntary locomotion is a region-specific, rather than a global phenomenon. The arterial response within the region presenting neurovascular coupling is tightly controlled by a central nervous system, while the venous response is under the influence of the peripheral system.

▼ When ligaments within the wrist are damaged, the resulting loss in range of motion and grip strength can lead to reduced earning potential and restricted ability to perform important activities of daily living. Left untreated, ligament injuries ultimately lead to arthritis and chronic pain. Surgical repair can mitigate these issues but current procedures are often non-anatomic and unable to completely restore the wrist’s complex network of ligaments. An inability to quantitatively assess wrist function clinically, both before and after surgery, limits the ability to assess the response to clinical intervention. Previous work has shown that bones within the wrist move in a similar pattern across people, but these patterns remain challenging to predict and model.
In an effort to quantify and further develop the understanding of normal carpal mechanics, we performed two studies using 3D in vivo carpal bone motion analysis techniques. For the first study, we measured wrist laxity and performed CT scans of the wrist to evaluate 3D carpal bone positions. We found that through mid-range radial-ulnar deviation range of motion the scaphoid and lunate primarily flexed and extended; however, there was a significant relationship between wrist laxity and row-column behaviour. We also found that there was a significant relationship between scaphoid flexion and active radial deviation range of motion. For the second study, an analysis was performed on a publicly available database. We evaluated scapholunate relative motion over a full range of wrist positions, and found that there was a significant amount of variation in the location and orientation of the rotation axis between the two bones. Together the findings from the two studies illustrate the complexity and subject specificity of normal carpal mechanics, and should provide insights that can guide the development of anatomical wrist ligament repair surgeries that restore normal function.

▼ While cognitive deficits have been described in the heterozygous Pten (+/-) KO mouse model of autism, little work has been done to demonstrate how corresponding
in vitro physiological alterations in this model may underpin these cognitive deficits
in vivo. As Pten KO (+/-) is known to alter electrophysiological characteristics of neurons
in vitro, this study measures the
in vivo electrophysiological characteristics of CA1 interneurons, pyramidal cells, and place cells which may underlie the spatial cognitive deficits seen in the model. Four transgenic conditional heterozygous <em>Pten
+/loxPloxP</em>;
Gfap-cre mice (HetPten) and four homozygous Pten littermate control mice were used in this study. This transgene drives cre expression and excision of the
Pten gene in hippocampal granule cells of the dentate gyrus, and neurons in CA2 and CA1, but not astrocytes.
In vivo local field potentials and single cell recordings were made in CA1 of each mouse during an open field foraging task in two distinct arenas. HetPten mice were found to have increased interneuron and pyramidal cell firing rates. In addition, place cells demonstrated abnormal properties including increased out-of-field firing rates, an increased number of fields, and trends towards larger field sizes that were less stable in comparison to controls. HetPten mice had slower CA1 fast gamma oscillations and more variable speed/theta oscillation correlations. Behaviorally, there were weak trends towards decreased motor output compared to controls. These data suggest that the electrophysiological alterations due to Pten KO (+/-) in mouse hippocampal neurons lead to hyperactivation of CA1 interneurons, pyramidal cells, and place cells.

▼ Bone defects, especially large bone defects, remain a major challenge in orthopaedic surgery. Autologous bone transplantation is considered the most effective treatment, but insufficient donor tissue, coupled with concerns about donor site morbidity, has hindered this approach in large-scale applications. Alternative approaches include implanting biomaterials such as bioactive glass (BG), which has been widely used for bone defect healing, due to having generally good biocompatibility, and can be gradually biodegraded during the process of new bone formation. Mesoporous bioactive glass (MBG) is a newly developed bioactive glass which has been proven to have enhanced in-vitro bioactivity; however the in-vivo osteogenesis has not been studied. A critical problem in using the bone tissue engineering approach to restore large bone defects is that the nutrient supply and cell viability at the centre of the scaffold is severely hampered since the diffusion distance of nutrients and oxygen for cell survival is limited to 150-200µm. Cobalt ions has been shown to mimic hypoxia, which plays a pivotal role in coupling angiogenesis with osteogenesis in-vivo by activating hypoxia inducing factor-1α (HIF-1α) transcription factor, subsequently initiating the expression of genes associated with tissue regeneration. Therefore, one aim of this study is to investigate the in-vivo osteogenesis of MBG by comparison with BG and β-TCP, which are widely used clinically. The other aim is to explore hypoxia-mimicking biomaterials by incorporating Cobalt into MBG and β-TCP. MBG and β-TCP incorporated with 5% cobalt (5Co-MBG and 5CCP) have also been studied in-vivo to determine whether the hypoxic effect has a beneficial effect on the bone formation. The composition and microstructure of synthesised materials (BG, MBG, 5Co-MBG, 5CCP) were characterised, along with the mesopore properties of the MBG materials. Dissolution and cytotoxicity of the Co-containing materials were also investigated. Femoral samples with defects harvested at 4 and 8 weeks were scanned using micro-CT followed by processing for histology (H&E staining) to determine bone formation.
Histology of MBG showed a slower rate of bone formation at 4 weeks than BG, however at 8 weeks it could be clearly seen that MBG had more bone formation. The in-vivo results show that the osteogenesis of MBG reciprocates the enhanced performance shown in-vitro compared to BG. Dissolution study showed that Co ions can be efficiently released from MBG and β-TCP in a controllable way. Low amounts of Co incorporated into the MBG and β-TCP showed no significant cytotoxicity and the Co-MBG powders maintained a mesopore structure although not as highly ordered as pure MBG. Preliminary study has shown that Co incorporated samples showed little to no bone formation, instead incurring high lymphocyte activity. Further studies need to be done on Co incorporated materials to determine the cause for high lymphocyte activity in-vivo, which appear to hinder bone formation. In conclusion, this…

▼ Nanosensors are an emerging tool for biomedical research and personalized medicine. By incorporating a recognition moiety and a reporter on a nanoscale platform, the nanosensor has displayed its ability to continuously monitor physiological molecules. To develop nanosensors for in vivo applications, characteristics such as sensitivity, dynamic range, selectivity, reversibility, biocompatibility, residency time, implantation, and clearance have to be considered. Choosing and optimizing the recognition moiety is crucial for the fabrication of an in vivo nanosensor. Currently, natural large molecules, such as proteins and nucleic acids, enzymes, and synthetic small molecules have all been used as recognition moieties. In this thesis, we will demonstrate two nanosensors using different recognition moieties to measure acetylcholine and glucose, respectively. First, acetylcholine is a neurotransmitter associated with cognition, learning, and memory. Previously, the detection of acetylcholine relied on microelectrode and microdialysis, which suffer from invasiveness and limited spatial resolution respectively. To overcome these issues, we developed a nanosensor to detect acetylcholine using magnetic resonance imaging (MRI). Butyrylcholinesterase (BuChE) serving as the recognition moiety, and pH-sensitive contrast agents serving as the reporter, are immobilized on the surface of a nanoparticle. Enzymatic hydrolysis of acetylcholine created a pH-drop in the microenvironment close to the surface of the nanoparticle, which was detected by the contrast agents leading to an increase in signal intensity. Delivered to the brain of rats, this nanosensor detected drug-induced release of acetylcholine. Second, we detected glucose as the first example of small molecule detection using an optode format. The level of glucose is an important parameter to determine the dose of insulin therapy. So far, the clinically used glucose monitors are all based on the enzymatic oxidation of glucose. To extend the residency time of the glucose sensor, we developed a glucose-sensitive nanofiber based on a small molecule boronic acid as the recognition moiety. By incorporating boronic acids containing an electro-withdrawing group, the nanofiber managed to continuously detect glucose at physiological pH with an improved in vivo residency time.

Dans ce contexte, nous avons analysé le transfert des informations thalamiques dans les GB en enregistrant, in vivo, les réponses évoquées au niveau de la structure de sortie des GB, la substantce noire pars reticulata (SNr) soit par la stimulation électrique ou optogénétique du CM/Pf. Ensuite, nous avons étudié les composantes des GB impliquées dans ces réponses en analysant les réponses évoquées par l'activation optogenetique spécifique des voies thalamo-striée, thalamo-subthalamique ou thalamo-nigrale. À la fois l'activation électrique et optogenetique du CM/Pf évoquent des réponses complexes dans la SNr qui sont composées d'une inhibition qui peut être précédée et/ou suivie d'excitations. L'inhibition et l'excitation tardive dépendent de l'activation des voies trans-striatales, alors que les premières excitations mettent en jeu les voies thalamo-subthalamique et thalamo-nigrale. Nous avons également étudié l'impact des interneurones cholinergiques du striatum ainsi que les afférences dopaminergiques sur le transfert des informations thalamiques dans les GB. Pour ce faire, nous avons enregistré les réponses évoquées au niveau des neurones de projection du striatum suite à la stimulation électrique du CM/Pf avec ou sans l'inhibition optogénétique des CINs. Nous serons alors en mesure de déterminer comment les CINs sont impliqués dans le transfert des informations thalamiques au sein des GB.
The centre median/parafascicular (CM/Pf) of the thalamus has recently emerged as a component of interest in the context of Parkinson’s disease. Thus normal and pathological dynamics of BG cannot be fully understood unless it is taken into account. Here, we analyzed the transfer of CM/Pf information through BG by recording, in vivo, the evoked responses of BG output neurons in the substantia nigra pars reticulata (SNr) to either electrical or optogenetic CM/Pf stimulations. Then, we investigated the BG components involved in these responses by analyzing the responses evoked by specific optogenetic activation of the thalamo-striatal, thalamo-subthalamic or thalamo-nigral pathways. Both electrical and optogenetic activation of CM/Pf evoke complex responses in SNr that are composed of an inhibition that can be preceded and/or followed by excitations. The inhibition and the late excitation rely on the activation of the trans-striatal pathways, whereas the early excitations involve thalamo-subthalamic and thalamo-nigral projections. We are currently analyzing whether and how the striatal cholinergic interneurons (CINs) and the dopaminergic afferent system modulate the transfer of thalamic information within the BG. For the second part of my project, we analyzed the treatment of thalamic information from CM/Pf at the level of the striatum. To do this, we…

▼ Introduction: Gap junctions allow direct cell-to-cell communication and form electrical synapses between neurons primarily via the gap junction protein connexin36 (Cx36). We examined the potential contribution of Cx36 in spinal dorsal root ganglia and peripheral nerves to the classic triple response (flare, wheal, and edema) following stimulation of nociceptors. The flare reflects increased blood flow beyond the injured area and the wheal is due to changes in the vascular permeability. Studies conducted in the 1980s suggested that electrical coupling between unmyelinated C-fibers in the periphery may contribute to these responses. Cx36 is a protein allowing gap junction formation between neurons.
Objectives: We aimed to quantify the contribution of Cx36-containing gap junctions to plasma extravasation responses following stimulation of nociceptors.
Methods: Wild-type (WT) and Cx36 knockout (KO) mice lacking this protein in all neurons were used for studies in which application of noxious stimuli (xylene, formalin, electrical stimulation of the sciatic nerve) was performed. Extravasation of Evans Blue dye from the circulation in the limbs was monitored via spectrophotometry, laser Doppler flux and in
vivo fluorescence imaging after noxious stimulation in anesthetized mice.
Results: A small but non-significant difference was found between KO and WT animals in the extravasated EB dye after front-paw’s chemical stimulation with xylene. A trend for greater responses as well as a faster rate of change in the Evans Blue fluorescence was found within the first 2-5 minutes after xylene application in WT vs. KO mice.
Conclusions: The enhanced early vascular response observed in this study after nociceptor stimulation in the WT animals as compared to the KO animals is consistent with earlier reports of direct electrical coupling between C-fibers and with evidence of Cx36 expression in small sensory neurons. These results suggest that Cx36 transiently contributes to the triple response.

▼ Understanding how memory, learning and reward work in unison to form adaptive and sometime maladaptive behaviour is at the forefront of modern neuroscience. The largest unmet need in treating maladaptive reward learning behaviours such as addiction is maintaining long-term abstinence and preventing relapse after re-exposure to drug-associated cues. Nicotinic acetylcholine receptors (nAChR) have been implicated in responses to drugs of abuse other than nicotine (Rahman et al., 2015) and the aim of this work was to characterise the role of α7 nAChRs in morphine reward learning using conditioned place preference (CPP). The α7 nAChR antagonist methyllycaconitine (MLA) was used to determine if these receptors contribute to specific stages of drug-paired learning, namely acquisition, expression, reconsolidation or reinstatement of morphine-CPP. In 7-8week old C57BL/6J mice MLA (4mg/kg, s.c), given 20 minutes prior to a conditioning dose of morphine (10mg/kg, i.p) or post-test trial, had no effect on the acquisition, reconsolidation or expression of morphine-CPP. However, when given 20 minutes prior to a priming dose of morphine (5mg/kg, i.p), MLA (4mg/kg, s.c) significantly inhibited drug-induced reinstatement. The mechanisms of this effect were investigated using glutamate receptor autoradiography. Changes in 2-Amino-3-(3-hydroxy-5-methyl-isoxazol-4-yl)propanoic acid (AMPA) and N-methyl-D-aspartate (NMDA) binding were examined in mice treated with either saline or MLA at morphine reinstatement. There were no significant changes in NMDA receptor binding (using [3H]MK-801) but morphine reinstatement significantly increased [3H]AMPA binding in the CA1/2 of the ventral but not dorsal hippocampus, or in any other brain regions examined (including mPFC, nucleus accumbens, amygdala and VTA). The selective increase in the hippocampus was partially antagonised by MLA, linking α7 nAChR activation to glutamatergic synaptic plasticity in the hippocampus. Intracranial infusions of MLA into the ventral but not the dorsal hippocampus or medial prefrontal cortex blocked reinstatement to morphine-CPP in male Wistar rats.
