▼ Mycobacterium tuberculosis (M.tb) is the causative agent of pulmonary tuberculosis (TB). Over 25% of the world’s population is estimated to be infected with tuberculosis, yielding over 10 million new cases and over 1.5 million deaths in 2017 alone. This is all despite the near universal implementation of bacille Calmette-Guérin (BCG) vaccination across TB endemic areas. BCG is capable of preventing childhood disseminated forms of disease but fails to induce potent immunity within the lung. We expect this to in part play a role in the lack of protection against pulmonary TB. Our lab has developed a human adenovirus serotype 5 vaccine expressing the M.tb antigen Ag85A (AdHu5Ag85A). When delivered directly to the respiratory mucosa (RM), AdHu5Ag85A has proven to be safe and immunogenic, generating both CD4 and CD8 T cell responses within the lung. We have found that RM AdHu5Ag85A vaccination also generates a long-lasting population of memory macrophages in the airway and lung, that are primed to better control early M.tb infection. Importantly, this was a vaccination route-dependent mechanism. Memory macrophages express a trained innate immune phenotype as they express high levels of MHC II, are highly glycolytic, and produce more IL-12 upon re-stimulation. Importantly, utilization of an in vivo T cell depletion approach allowed us to show that these memory macrophages are capable of limiting early M.tb infection independent of T cells. Our findings indicate that RM vaccination may be advantageous to parenteral routes by not only drawing antigen specific T cells into immunologically restricted lung mucosa but also generating a memory macrophage population within the lung. Induction of memory macrophages within the airway helps overcome early innate immune suppression by M.tb.

Tuberculosis (TB) is a pulmonary disease responsible for 10 million new clinical cases and more than 1 million deaths annually. Over one quarter of the world is believed to be infected with TB. This is despite the near-universal administration of bacille Calmette-Guérin, a preventative TB vaccine, and an effective, but lengthy antibiotic treatment. With antibiotic resistance on the rise, developing a protective vaccine against TB is more important than ever. Tuberculosis has confounded researchers for decades and has thus escaped development of a more effective vaccine. One of the ways to improve a TB vaccine would be to inhale it, to have local effects at the main site of TB infection in the lung. We found that by aerosolizing our vaccine, we can impact local immunity within the lung in a way that has never before been described, opening new avenues for TB research.

▼ Psychosocial distress,
characterized by increased perceived stress, anxiety and mood
disturbance, is a common response of women to a diagnosis of breast
cancer (Northouse, 1992; Pettingale et al., 1988; Stark and House,
2000; Witek-Janusek et al., 2007). This psychosocial distress leads
to activation of the hypothalamic-pituitary-adrenocortical (HPA)
axis and increased circulating glucocorticoids (GCs) (Chrousos,
2000; Chrousos and Gold, 1992; Schoneveld and Cidlowski, 2007).
Increased psychosocial distress and increased HPA activation can
lead to immune dysregulation consisting of reduced natural killer
(NK) cell activity (NKCA) (Biondi, 2001; Kiecolt-Glaser et al.,
1987; Kiecolt-Glaser et al., 2002; Witek-Janusek et al., 2008;
Witek-Janusek et al., 2007). This is of particular relevance to
women with breast cancer as altered immune cell function is
important for tumor control (Curcio et al., 2003; D'Anello et al.,
2010; Diefenbach and Raulet, 2002; Hartman et al., 2011; Kishimoto,
2005; Knupfer and Preiss, 2007; Street et al., 2001; van den Broek
et al., 1996). The psychological distress in response to a
diagnosis of breast cancer diagnosis has relevance for women with
breast cancer, as it may contribute to poor cancer
outcome. Yet little is known about the molecular
mechanism(s) by which psychosocial distress results in NK cell
dysregulation. The overall purpose of this project was to evaluate
a potential mechanism posited to underlie altered NK cell function
observed in women with breast cancer. Increased psychosocial
distress increases GCs like cortisol which can impact NK cell
function; therefore cortisol levels were measured. Morning cortisol
rise inversely correlated with NKCA, such that women with decreased
NKCA exhibited an elevation in the morning cortisol rise.
Additionally, in vitro treatment of a human NK cell line, NK92
cells, treated with a synthetic GC (dexamethasone) resulted in
decreased NKCA. Together these results suggest that cortisol
altered lytic function of NK cells. As GCs have been shown to alter
cell function by altering epigenetic patterns, global histone
modifications were investigated. In both ex vivo analysis of NK
cells derived from peripheral blood of women with breast cancer and
NK92 cells treated with GCs significant reductions in global
acetylation of histone 4 lysine 8 (H4-K8-Ac) were observed, when
compared to the age-matched Control women or untreated NK92 cells,
respectively. These reductions in H4-K8-Ac correlated with NK cell
lytic function as measured by NKCA and intracellular perforin
levels in NK cells. Further others show GCs alter epigenetic
patterns through recruitment of HDACs, thus this was investigated.
Findings show decreased global H4-K8-Ac patterns in NK cells were
associated with increased nuclear localization of HDAC2, suggesting
that GCs recruit HDAC2 into the nucleus causing decreased global
H4-K8-Ac and NKCA. These data identify decreased global H4-K8-Ac
and increased nuclear localization of HDAC2 as potential markers of
decreased NK cell lytic…

▼ During periods of psychosocial
distress glucocorticoids (GCs) are known to reduce the lytic
activity of natural killer cells (NKCA). Glucocorticoid treatment
also reduces acetylation of histone residues; however, the
glucocorticoid receptor (GR) lacks deacetylase activity. GR is
known to interact with histone deacetylases (HDACs) and with
corepressors that mediate gene transrepression. In this
investigation, GC induced histone deacetylation was demonstrated to
be due to GR recruitment of HDAC1 and the corepressor complex SMRT.
These data show that reduced acetylation of immune functional genes
associated with NKCA is likely due to histone deacetylation by
HDAC1 and transrepression of those genes by SMRT.

▼ Periodontal
disease is among the most common of inflammatory conditions and is caused by bacterial and host derived factors. The presence of bacteria drives the recruitment of neutrophils, professional phagocytes, to migrate to specific oral sites where they produce potent antimicrobials to kill their target. However, this inflammation and production of antimicrobials must be strictly regulated to minimize collateral host tissue damage. Human neutrophils recognized the oral pathogen
Filifactor alocis through Toll-like receptor (TLR) 2 and upon binding, activated both p38 MAPK and ERK signaling pathways, known to be involved in neutrophil cell migration and degranulation.
F. alocis also stimulated secretory vesicle and specific granule exocytosis and enhanced chemokinetic and chemotactic migration to interleukin (IL)-8, a key chemoattractant found in the oral cavity (Chapter 2). Once these challenged neutrophils have arrived at their targeted site, they will employ oxidative-mediated killing mechanisms, operating intracellularly in the bacterial-containing phagosome, and extracellularly, in the extracellular space. Neutrophils effectively perform phagocytosis to internalize
F. alocis into their phagosomal compartment, however minimal intracellular respiratory burst response is produced. In addition,
F. alocis-challenged neutrophils produced minimal superoxide release, however the bacterial challenge primed neutrophils for an enhanced respiratory burst response.
F. alocis survived neutrophil oxygen-dependent intracellular and extracellular killing mechanisms up to 4 h post-infection (Chapter 3). Activated neutrophils can also undergo neutrophil extracellular trap (NET) formation as a means to trap and potentially kill targets. NETs have been described to be formed in the oral cavity in response to oral biofilms.
F. alocis failed to induce NETs from neutrophils, which may indicate this bacterium is unique to the oral cavity, as other oral bacteria
Streptococcus gordonii and
Peptoanaerobacter stomatis induce NETs. However,
F. alocis can manipulate neutrophils and reduce their NET formation capacities to known pharmacological (PMA) and bacterial (
S. gordonii) inducers (Chapter 4). Overall, our results are the first to show how
F. alocis effectively evades human neutrophil killing mechanisms and manipulates some of their functional responses. These results provide information about the pathogenic potential of
F. alocis which would help delineate the role of this emerging pathogen in the development of periodontal
disease.

▼ Cytotoxic T-lymphocyte antigen 4 (CTLA-4) is a T cell surface protein that is homologous to CD28 and binds to the B7 family of ligands. Unlike CD28, CTLA-4 interaction transmits a negative signal in T cells, leading to suppression of proliferation. CTLA-4 is constitutively expressed on regulatory T cells (Tregs) but is also inducible in effector T cells. The mechanisms driving transcriptional regulation of CTLA-4 are poorly understood. Our previous work identified a bona fide NFAT1 binding site in the proximal promoter for effector T cells. In addition, we found histone acetylation occurred after stimulation.
As a result of its role in suppressing T cell proliferation, CTLA-4 is important for regulation of T cell responses. CTLA-4-immunoglobulin fusion proteins have shown efficacy to quell the overactive immune system in various types of autoimmune diseases. Alternatively, blocking antibodies to CTLA-4 have been used in cancer therapies to boost the anti-tumor immune response. Malignant cells of cutaneous T cell lymphoma (CTCL) express elevated levels of CTLA-4, which may contribute to reduced
tumor immunity as the
disease progresses. The objective of this work was to identify mechanisms of transcriptional regulation of CTLA-4 to better understand how this gene can be modulated to potentially cater the immune response for a variety of immune-mediated diseases.
The major findings of this work include a mechanism by which proteasome inhibition augments CTLA-4 transcription in normal primary human CD4 T cells. The Th2 associated transcription factor GATA3 is both elevated and activated by phosphorylation after treatment with the proteasome inhibitor bortezomib, which in turn leads to CTLA-4 transcriptional activation in primary CD4 T cells. This finding may in part explain the increase in CTLA-4 found in CTCL, where GATA3 is also more abundant, particularly in its phosphorylated state. The increased CTLA-4 in our primary cell model is capable of suppressing T cell proliferation, demonstrating the potency of transcriptional modulation of this gene. Additionally we explored epigenetic and topological modifications that occur for CTLA-4 activation. We found the histone acetyltransferases p300 is responsible for histone 3 acetylation at the CTLA-4 promoter, and its activity is required for CTLA-4 transcription. We also discovered a previously undiscovered role for topoisomerase I in expression of a variety of induced genes, including CTLA-4. These results define novel mechanisms governing transcriptional activation of CTLA-4 in human effector CD4 T cells.

▼ Herpes stromal keratitis (HSK) is a chronic immuno-inflammatory ocular
disease caused by Herpes simplex virus-1 (HSV-1) infection in the cornea. HSK is characterized by the development of corneal opacity and angiogenesis accompanied by the loss of corneal transparency. Despite extensive studies on inhibiting corneal angiogenesis and strategies to reduce HSK
disease development, a key underlying mechanism to maintain an intact and a transparent corneal surface during HSK
disease progression, remain obscure. Our study has addressed possible causes for the HSK
disease severity by identifying the key factors such as the development of inflammatory hypoxia, reduced tear volume, Inflammation of extra-orbital lacrimal gland and the conjunctiva and the transdifferentiation of the corneal epithelium in the HSK developing eyes. Intriguingly, our study also emphasizes the protective role of IGFBP-3 in inhibiting the severe
disease progression of HSK.
During the pre-clinical and the clinical
disease phase of HSK, the influx of neutrophils have been studied as the most prominent innate immune cell type. Development of corneal hem- and lymph-angiogenesis, opacity and epithelial defects hinders the clear vision and is known to be the cause of the increased neutrophil influx in HSV-1 infected cornea. Previous studies have indicated that the influx of neutrophils into mucosal tissue can re-model the development of inflammatory hypoxia. Therefore, the aim of this study was to investigate the development of hypoxia and hypoxia-associated gene expression during the progression of HSK
disease. Our results showed an increased influx of neutrophils during the clinical
disease of HSK that leads to the development of hypoxia, and the upregulation of hypoxia-associated genes. This study provided us novel insights on the prevalence of the glycolytic metabolism in the HSK developing eyes. Additionally, our data demonstrated that the blocking of Hypoxia-Inducible Factor (HIF) with Acriflavine alone might not be an efficacious drug in reducing HSK
disease severity. Overall, these results pave way for using novel therapeutic targets that play a dual role to block HIF and control corneal inflammation during HSK.
Maintaining a healthy corneal epithelium, retaining a steady tear volume and its secretion could be the other factors that may aid in alleviating HSK
disease severity. Mounting evidence corroborates corneal nerves as a critical factor in the maintenance of corneal integrity and homeostasis of the ocular surface by mediating the reflex actions of blinking and tearing. In support, in a mouse model during HSV-1 ocular infection, corneal nerve damage has been demonstrated. Hence, corneal transparency and clear vision are critically dependent upon the integrity of corneal tissue maintained by the intricate network of corneal nerves, the presence of intact corneal epithelium and tear film that is controlled by a cross-talk between the components of the lacrimal functional unit. Our study showed a reduced…

▼ Plasma cell neoplasms (PCN), including multiple myeloma, are tumors of terminally differentiated B cells. Despite a significant research effort, and numerous advances in therapy, most tumors of this B cell lineage remain incurable. To this end, understanding factors which are critical for the development of PCN may lead to new avenues for therapy. Interleukin-6 (IL-6) is a pleiotropic, pro-inflammatory cytokine which supports the growth, proliferation, and survival of myeloma cells.
We found that inflammation, and in particular, IL-6 is critical for the development of PCN. In order to determine if tumor microenvironment (TME) or B cell-derived IL-6 was more important in PCN development, we utilized an adoptive transfer system of tumor formation. By adoptively transferring premalignant B cells into recipients, and then providing the B cells with an inflammatory microenvironment through the use of pristane, we were able to generate donor tumors in recipient mice. Utilizing this method, a series of adoptive transfers were performed to determine the primary source of IL-6 in murine PCN development. We discovered that TME-derived IL-6, and not B cell-derived IL-6, is most critical for PCN development.
Furthermore, in studying the lesions in B cell development which lead to tumor formation, we discovered that IL-6 collaborates with the proto-oncogene c-Myc in spontaneous germinal center (GC) formation. The spontaneous GCs were accompanied by a robust follicular T helper cell response. In characterizing the genetic lesions which lead to the GC formation, we discovered that Myc-transgenic mice develop a significant increase in the population of B1a B cells. Furthermore, these B1a B cells infiltrate the spontaneous GCs of double transgenic Myc/IL-6 mice. Lastly, utilizing our adoptive transfer method, we determined that the germinal center response is necessary for the development of PCN in mice.
Lastly, we focused our efforts on another oncogene which collaborates with IL-6, BCL-2. Double transgenic BCL-2/IL-6 mice develop PCN and spontaneous GCs. Of interest however, the adoptive transfer of BCL-2/IL-6 B cells results in tumor formation without the use of pristane. Furthermore, the adoptive transfer recipients develop bone lesions, hind limb paralysis, and a monoclonal gammopathy. This model closely recapitulates many of the pathophysiological features seen in human PCN. This new model promises to be important for future studies into PCN development and treatment.

▼ Leishmaniasis refers to the group of diseases caused by pathogenic protozoan parasites of the genus Leishmania. Nearly all human Leishmania spp. infections are initiated in mammalian skin through the bite of the phlebotomine sand fly vector. However, clinical manifestations vary greatly with infecting species. Leishmania major establish infection locally within the skin and cause chronic ulcerating skin lesions at the local cutaneous site of inoculation, in a syndrome known as Cutaneous Leishmaniasis (CL) Leishmania infantum parasites metastasize from the site of skin infection via unknown mechanisms, and establish infection within visceral organs usually without inducing skin pathology, resulting in the potentially fatal disseminated
disease, Visceral Leishmaniasis (VL). Mouse studies suggest early responses at the skin infection site are critical determinants of subsequent adaptive immune responses in leishmaniasis, yet few studies address the role of keratinocytes, the most abundant immunoactive cell in the epidermis. We hypothesize that Leishmania infection causes keratinocytes to produce immunomodulatory factors that influence the outcome of infection.
Incubation of primary or immortalized human keratinocytes with L. infantum or L. major elicited dramatically different responses. Keratinocytes incubated with L. infantum significantly increased expression of pro-inflammatory genes IL6, IL8, TNF, and IL1B by RT-qPCR; whereas keratinocytes exposed to L. major did not. Similar to live parasites, L. infantum-derived exosomes induced more IL8 mRNA compared to control or L. major-derived exosomes. Western blotting confirmed NFkBp65 phosphorylation in keratinocytes exposed to L. infantum but not L. major. However, no evidence of L. major inhibition of TNF-induced NFkBp65 phosphorylation was observed in simultaneously treated keratinocytes. To examine whether keratinocytes influence proximal host cells, L. infantum-infected human monocytes were co-cultured with keratinocytes across a transwell membrane. These studies suggested L. infantum-exposed keratinocytes release soluble factors that enhance monocyte control of intracellular L. infantum replication. L. major-exposed keratinocytes had no comparable effect. These data suggest L. infantum and L. major differentially activate keratinocytes to release factors that limit infection in monocytes.
Microarray analyses performed on human keratinocytes exposed to either L. infantum or L. major promastigotes identified a limited number of transcripts increased by parasite exposure. Consistent with RT-qPCR observations, several inflammatory cytokine and chemokine genes were more strongly induced in L. infantum-exposed keratinocytes compared to L. major-exposed keratinocytes. Pathway analyses of genes induced by L. infantum-treated keratinocytes suggested that this interaction may induce neutrophil recruitment. Notably, AP1 transcription factor subunit genes were significantly down regulated in L. major-treated compared with L. infantum-treated or…

▼ Tim-3 (for T cell immunoglobulin and mucin domain 3) is a surface molecule expressed throughout the immune system that appears to mediate both stimulatory and inhibitory effects. Tim-3 is expressed by activated CD4 and CD8 T cells, which suggests a direct role in the regulation of T cell responses. Consistent with this possibility, previous studies have shown that blockade of interactions between Tim-3 and ligands in the context of mouse models for autoimmunity and chronic infection can augment T cell responses, which indicates that Tim-3 functions as an inhibitory receptor for T cells. However, other studies have provided evidence that Tim-3 can function to promote T cell responses, which suggests that Tim-3 acts as a stimulatory receptor. In addition, biochemical and cell culture studies have shown that Tim-3 can induce both inhibitory and stimulatory signaling pathways. These conflicting findings highlight that the role of Tim-3 in regulating T cell responses remains unclear and warrants further investigation. My studies sought to determine the role of Tim-3 in regulating T cell responses to microbial infections in vivo and to acute stimulation in vitro. Using Tim-3 KO mice and Tim-3 KO cells, I demonstrate that Tim-3 can directly enhance CD8 T cell responses to Listeria monocytogenes (LM). I also provide evidence that Tim-3 indirectly regulates CD4 T cell responses to LM. Alternatively, I show that Tim-3 may inhibit CD4 and CD8 T cell responses to the chronic viral infection LCMV-Clone 13, and that Tim-3 may be dispensable for T cell responses to the acute viral infection LCMV-Armstrong. Additionally, I demonstrate that Tim-3 expression in response to acute stimulation in vitro or in vivo marks populations of CD4 Th1 cells that are enriched for cells with effector function as measured by cytokine production and markers for degranulation. Collectively, these data suggest that Tim-3 may differentially regulate T cell effector function in a manner that is dependent on
infectious environment encountered.

▼ The immune system has evolved to fight off numerous pathogens. The first line of defense against these pathogens are innate immune cells. Innate immune cells ingest pathogens and a family of cytosolic proteins, NOD-like receptors (NLR) and AIM2-like receptors (ALRs), recognize conserved sequences on pathogens. Recognition of pathogens by NLRs and ALRs alerts the immune system to the presence of an invader and subsequent control of infection. NLRs and ALRs also recognize endogenous cell danger signals that are released during cell stress. Pathogens and tumor cells are capable of growing in a host with limited detection by the immune system. This evasion leads to a suboptimal immune response to both the bacteria and cancer cells resulting in enhanced infection and tumor growth. We investigated how the bacteria Francisella tularensis escapes recognition by the AIM2 receptor. We identified a novel gene important in bacterial folate metabolism that helps the bacteria escape immune recognition. The identification of this gene will help in the development of treatments for F. tularensis infection. In addition, we investigated the role of the NLRC4 receptor in a mouse model of melanoma. We found that mice lacking NLRC4 developed significantly larger tumors and had a diminished immune response compared to mice that expressed NLRC4. We also observed decreased expression of NLRC4 in metastatic melanoma tissue in humans. Thus demonstrating that NLRC4 is important for initiating an immune response to melanoma and down regulating expression of NLRC4 is a way for the tumor to evade the immune response.

▼ The factors that contribute to successful colonization of a novel host species by a pathogen remain unclear. One likely factor determining host shift success is the early interaction between host and pathogen at the very moment of the host shift event. How does a novel host respond to a pathogen insult immediately following infection? To answer this question, the Drosophila model was used along with the highly pathogenic Drosophila C virus, host fitness assays and metabolomic analysis to measure the host’s response to a novel pathogenic infection. As Wolbachia can interfere with RNA virus infection success, a new method was developed to reliably and quickly eliminate Wolbachia from the flies. Once the flied were confirmed to be Wolbachia-free, they were injected with DCV. Females of the native host (D. melanogaster) and the novel host (D. mauritiana) were injected with DCV or Schneider’s media, subjected to fitness tests, frozen in liquid nitrogen and their metabolomes were analyzed. The novel host had equal or increased fitness (fecundity, hatchability, pupation, number of pupae, and number of adults), but significantly higher mortality. Metabolomic analysis revealed that many metabolites from a variety of metabolic pathways were significantly different. A wide range of stress-related metabolites were upregulated in the native host, but not in the novel host. These results support the hypothesis that the initial physiological interaction between a pathogen and its novel host is critical for the survival of the host or the success of the pathogen.

▼ Three potential driver genes were identified by use of retroviral mutagenesis in the newly developed iMyc model of B cell malignancy. To do so, iMyc mice, which bear an inserted copy of c-Myc in the IgH locus, were treated with MOL4070LTR to favor the development of B cell malignancies. After tumor development, B cell origin tumors were identified by use of immunohistochemistry and selected for downstream analysis. Three genes were chosen as potential driver genes and validated in mouse or human
disease as involved in
disease or directly in malignancy. These genes are CD82, IRAK2 and DNMT3a.

▼ The immunosuppressive effects of chronic alcohol abuse are profound, wide-ranging and readily apparent at the body's barriers. In the skin, alcoholism is associated with an increased incidence and severity of infection; yet the precise immunologic alterations responsible remain poorly understood. Cutaneous homeostasis and immunity are afforded via coordinated efforts of tissue-specific immune cell networks. Here, the Meadows-Cook murine model of alcoholism was used to investigate the impact of chronic ethanol (EtOH) exposure upon the following: 1) the composition and function of skin-resident dendritic cells (DCs) and T cells in preimmune mice 2) infection outcome and host defense following Staphylococcus aureus skin infection 3) the induction of cutaneous oxidative stress Chronic EtOH feeding caused a baseline reduction in skin DCs and T cells with the most pronounced effects occurring in self-renewing compartments (i.e, Langerhans cells and γδ T cells). In addition, we found that EtOH-induced immune cell subset loss was often associated with dysfunction of the remaining population. For DCs, EtOH-induced hyporesponsiveness was observed in both in vitro and in vivo migration assays. Defects in the former system could be corrected via TNFα restoration. EtOH-induced dysfunction in skin T cells was evident by the decreased upregulation of JAML and diminished production of IL-17 by epidermal and dermal γδ T cells respectively. In a murine model of EtOH withdrawal, some but not all of the EtOH-induced defects occurring in skin DCs and T cells recovered after cessation of EtOH exposure. Prior to this work, the impact of chronic EtOH exposure upon the cutaneous immune system had not been investigated in a murine model of infection. Using a novel method of cutaneous S. aureus challenge, evidence of exacerbated staphylococcal
disease in EtOH-fed mice included skin lesions that were larger and contained more organisms, greater weight loss and increased bacterial dissemination. Infected EtOH-fed mice demonstrated poor maintenance and induction of PMN responses in the skin and draining LNs respectively. Additionally, altered PMN dynamics in the skin of these mice corresponded with reduced production of IL-23 and IL-1β by CD11b+ myeloid cells and IL-17 production by γδ T cells, with the latter defect occurring in the draining LNs as well. In addition, IL-17 restoration via intradermal injection improved bacterial clearance defects in EtOH-fed mice. Taken together, these findings show that the EtOH-induced increase in S. aureus-related injury/illness (i.e., weight loss, bacterial burden, lesion size) corresponds with defects in the IL-23/IL-17 inflammatory axis and poor PMN accumulation at the site of infection and draining LNs. Finally, two complementary tools (mice deficient in molecules that promote or inhibit reactive oxygen species induction) were used to investigate the role of oxidative stress as a driver of cutaneous immune dysfunction. In these studies intriguing evidence was obtained indicating…

▼ CD4 and CD8 T cells are constantly exposed to inflammatory signals that influence
diverse functional outcomes during infections and certain autoimmune disorders. One of
the signals controlling CD4 and CD8 T cell functions is the inflammatory cytokine IL-12.
Previous studies have focused on how IL-12 regulates CD4 and CD8 T cell functions when
present during or after the activation of the T cell receptor (TCR). However, based on
murine studies, we have only recently begun to appreciate that exposure to inflammatory
signals, driven in part by IL-12, could alter how CD4 and CD8 T cells respond to TCR
stimulation. Although intriguing, these studies have left several questions unanswered.
Does IL-12 similarly regulate the function of human T cells? If so, what is the exact
molecular mechanism by which IL-12 mediates these effects? To address these critical
questions, we examined how IL-12 pretreatment altered human CD4 and CD8 T cell responses
to subsequent TCR stimulation.
In
CHAPTER III, we examined how prior exposure to IL-12 alters the responses of human
CD4 T cells to subsequent TCR stimulation. Some of our key findings were that IL-12
pretreatment increased the production of IFN-γ, TNF-α, IL-13, IL-4 and IL-10 after TCR
stimulation, suggesting that prior exposure to IL-12 potentiates the TCR-induced release
of a range of cytokines. Based on the intracellular staining and mRNA expression data,
we concluded that the IL-12-mediated increased production of a range of cytokines was a
consequence of at least two separate mechanisms, increased mRNA expression for IFN-γ and
increased release of TNF-α, IL-13, IL-4 and IL-10. In
CHAPTER IV, we explored the
mechanisms by which IL-12 pretreatment altered human CD4 T cell responses to TCR
stimulation. We observed that IL-12 pretreatment increased the phosphorylation of AKT,
P38 and LCK following TCR stimulation without altering other TCR signaling molecules,
suggesting that this potentially mediates the increase in transcription of cytokines. In
addition, the IL-12-mediated enhancement of cytokines that were not transcriptionally
regulated was partially driven by increased oxidative metabolism. Collectively our
results uncovered a novel function of IL-12 in regulating human CD4 T cell responses;
specifically, it enhanced the release of a range of cytokines potentially by altering
TCR signaling pathways and by enhancing oxidative metabolism. Then, in
CHAPTER V, we
examined the effects of IL-12 pretreatment in altering the responses of human CD8 T
cells to subsequent TCR stimulation. Our key finding was that pretreatment of human CD8
T cells with IL-12 resulted in increased IFN-γ…

▼ Mucosal Associated Invariant T (MAIT) cells are a subset of innate-like T cells, which are abundant in humans. They recognize antigens that are derived from bacterial riboflavin synthesis pathway metabolites, presented by highly conserved MHC-related 1 (MR1) molecules. Upon stimulation, MAIT cells rapidly produce several pro-inflammatory cytokines, such as IFN-γ, IL-17 and TNF-α, and also display direct cytotoxic capacity. These characteristics suggest that MAIT cells play a role in host defence against bacterial infections.
Although the microbial reactivity of MAIT cells has been defined, the detailed mechanism by which MAIT cells are activated during bacterial infection in vivo are still not fully understood. Using MR1-tetramers to specifically characterize MAIT cell responses during Salmonella enterica var Typhimurium (S. Typhimurium) pulmonary infection, it is shown in this dissertation that the infection-induced activation of MAIT cells largely depends on the presence of microbial-derived antigens, whereas the expansion of MAIT cells in vivo requires antigens as well as co-stimulatory signals, which can be provided by bacteria or a Toll-like receptor (TLR) agonist.
The results presented in this dissertation also demonstrate the protective role of MAIT cells in a murine pulmonary model with a human major pathogen, Legionella longbeachae. In response to infection, MAIT cells proliferate and accumulate at the infection site and contribute to cytokine responses. In the absence of MAIT cells, MR1-/- mice display an impaired and delayed bacterial clearance. MAIT cell-mediated protection is more apparent when CD4+ T cells are removed and can be enhanced by prior expansion with synthetic antigens and an adjuvant (TLR agonists). Notably, adoptively transferred MAIT cells can provide highly immunodeficient Rag2-/-γC-/- mice with full protection against lethal L. longbeachae infection and this protection is achieved, at least in part, by IFN-γ production.
In summary, this dissertation provides direct experimental evidence that MAIT cells are protective during bacterial infection. In addition, through exploring the requirements for MAIT cell activation and expansion in vivo, the studies revealed that the pre-expanded MAIT cells in mice were potentially protective and to suggest that MAIT cells can be harnessed as a vaccine target to elicit a “memory”-type protection.

▼ Thymus is a primary lymphoid organ responsible for proper development and selection Of T-‐cells. The thymic microenvironment, however, undergoes age related involution, Resulting in a reduction of the repertoire of T-‐cells that are produced, and a decreased Capacity to respond to new antigen. Even though significant thymic epithelial turnover occurs, it is unclear if postnatal thymic progenitors/stem cell are responsible for the maintenance of the TEC microenvironment. Here we use the K5rtTA:TetO-‐H2BGFP transgenic model to identify a slow cycling potential stem cells/progenitor population in the postnatal thymus. These cells were isolated, expanded in culture, and successfully differentiated into adipocytes, chondrocytes and osteoblasts. We identified that the culture expanded LRCs expressed the surface makers PDGFRα, PDGFRβ, SCA1, CD29, CD44, CD49f, and CD90 identical to markers Used to characterize mesenchymal stem cells. LRC were isolated and maintained As a thymic mesenchymal stem cell line (TMSC), which showed a limited Capability for forming a reaggregated thymus when combined with fetal epithelium. Dexamethasone treatment of the mouse resulted in depletion of the label as the Thymus recovered from drug induced involution, suggesting that LRC are recruited During thymic regeneration. Collectively these results demonstrate we have identified A stem cell population in the postnatal thymus that may play a role in the maintenance Of the thymic architecture.

▼ More than 64 million people in the US suffer from some form of periodontal
disease. Periodontal diseases are bacterial infections of the hard and soft tissues surrounding the teeth which can lead to tooth loss. Periodontal tissue destruction is caused by inflammatory host-pathogen interactions. Porphyromonas gingivalis is a major causative agent of periodontal diseases and is a keystone periodontal pathogen. The 55kDa immunodominant RagB outer membrane protein of P. gingivalis has been proposed to facilitate iron transport. However, potential interactions between RagB and the innate response have not been examined. RagB homologues in gut Bacteroidetes have been associated with inflammatory bowel
disease. Therefore, we hypothesized that RagB aids in virulence of P. gingivalis and elicits a pro-inflammatory host response in innate cells. We determined that RagB exposure led to the differential and dose-related expression of multiple genes encoding pro-inflammatory mediators (IL-1β, IL-6, IL-8, and CCL2) in primary human monocytes and to the secretion of TNF, IL-6 and IL-8. RagB was shown to be a TLR2 and TLR4 agonist that activated STAT4 and NFκB transcription factors. ΔragB mutants also induced a reduced inflammatory response compared to the wild type strain as well as reduced survivability when exposed to oral epithelial cells which adds evidence to the role of ragB in epithelial cell colonization. These results suggest that ragB elicits a major pro-inflammatory response in primary human monocytes and therefore could play an important role in the etiology of periodontitis and systemic sequelae.

▼ Influenza A virus (IAV) subtypes and even genotypes within subtypes can show differences in tropism (host, cell type), magnitude of infection, immune response and progression of illness. My dissertation focused on the development and use of two in vitro physiologically-relevant human cell culture models, well-differentiated normal human bronchial epithelial (wdNHBE) cells and human monocyte-derived macrophages (MDM) for the study of early IAV-host interactions. These models have given new insight into early host responses to seasonal H1N1 (BN59) and two pandemic A(H1N1)2009 viruses or H1N1pdm herein. The H1N1pdm are clinical isolates from a fatal (A/KY/180/10) and nonfatal (A/KY/136/09) case. In the wdNHBE model, KY180 showed a significantly higher titer as compared to the other two viruses at 24 hpi (hours post-infection). Interestingly, by microarray analysis, there were no significant differences in the host genome-wide expression intensity profiles of each virus following infection. Soluble cytokine measurements revealed increased apical and basal pro-inflammatory cytokine secretion overtime. A key finding from our data was greater basolateral secretion of cytokines (IL6, CCL5, CCL4 and CCL2) by KY180-infected wdNHBE cells. This finding suggests that the basolateral signals from infected epithelial cells may differ in their potential for recruitment and responses elicited by recruited monocytes/macrophages. In the second model, I used an in vitro model of recruited “resting” MDMs to study virus-host interactions of the clinical H1N1pdm isolates. These viruses replicated in MDM albeit inefficiently. While titers were similar and remained relatively low for all isolates, pro- and anti-inflammatory expression levels differed markedly between KY180 as compared to KY136 and BN59. KY180 had delayed expression at 8 hpi of pro-inflammatory genes (CCL5, TNF, IFN, CXCL10). This apparent delay in response to KY180 depended on the mode of viral entry. For KY180, this occurred primarily through macropinocytosis, mapping to the HA1 gene. In summary, my studies reveal subtle, yet important differences in IAV-host interactions that result in alterations of immune signaling in epithelial and macrophage cell culture models. Continued advancement of the in vitro human cell culture models for the study of IAV is important as they will allow mechanistic insight into the intricate biology of these viruses.

(more)
▼ AMP-activated protein kinase, AMPK, is a conserved serine/threonine kinase with a critical function in the regulation of metabolic pathways in eukaryotic cells. Recently, AMPK has been shown to play an additional role as a regulator of inflammatory activity in leukocytes. Treatment of macrophages with chemical AMPK activators, or forced expression of a constitutively active form of AMPK, results in polarization to an antiinflammatory phenotype. Additionally, we reported previously that stimulation of macrophages with antiinflammatory cytokines such as IL-10, IL-4 and TGF-ß results in rapid activation of AMPK, suggesting that AMPK contributes to the suppressive function of these cytokines. In the current study we investigated the role of AMPK in the regulation of macrophage antiatherogenic functions and demonstrated a new mechanism for AMPK’s role in mediating IL-10-induced gene expression and antiinflammatory effects. The expression of dominant negative (DN-) AMPKa1 in macrophages resulted in a spontaneous obese phenotype in mice associated with fatty liver and heart enlargement. The expression of constitutively active (CA-) AMPKa1 in macrophages resulted in decreased IL-6 production but increased expression of ABCA1 and ApoE. Compared to wild-type macrophages, AMPKa1-deficient macrophages failed to express atheroprotective genes including ApoE, LXRa, and ABCA1 in response to IL-10. Mechanistic studies revealed that IL-10-stimulated wild-type macrophages displayed rapid activation of PI3K and its downstream target Akt, an effect that was not seen in macrophages generated from AMPKa1-deficient mice. Treatment with the PI3K inhibitor LY294002 blocked IL-10’s ability to induce Akt activation but not AMPK activation, suggesting that IL-10-mediated activation of AMPK is independent of PI3K. CA-AMPKa1 macrophages displayed elevated PI3K and CREB activation in response to IL-10 compared to the empty vector transfected macrophages. IL-10 stimulation resulted in increased mTORC1 activity, an Akt downstream target, an effect that was reduced in AMPKa1-deficient mice. IL-10 induced phosphorylation of both Tyr705 and Ser727 residues of STAT3 in an AMPKa1-dependent manner, and these phosphorylation events were blocked by inhibition of CaMKKß, an upstream activator of AMPK, and by the mTORC1 inhibitor rapamycin, respectively. The impaired STAT3 phosphorylation in response to IL-10 observed in AMPKa1-deficient macrophages was accompanied by reduced SOCS3 expression and an inadequacy of IL-10 to suppress LPS-induced proinflammatory cytokine production. Overall, our data demonstrate that AMPKa1 is required for IL-10 activation of the PI3K/Akt/mTORC1 and STAT3/SOCS3 antiinflammatory pathways regulating macrophage polarization, a mechanism with broad-reaching applicability in immune homeostasis and in inflammation-associated diseases such as atherosclerosis, autoimmune diseases, and obesity.

▼ Influenza A virus (IAV) is a minus-sense, segmented, single-stranded RNA virus that infects the respiratory tract of humans and can cause severe illness. Novel IAV variants perpetually emerge on every continent, and the emergence of variants with increased transmissibility and/or pathogenesis in the human population is a serious concern for global public health. Infection with IAV typically causes an acute, self-limiting upper respiratory tract
disease. However, severe IAV
disease is characterized by infection of the lower respiratory tract which can lead to pneumonia and may result in the development of acute respiratory distress syndrome (ARDS). Viral and host contributions to the development of ARDS are poorly understood, however IAV pathogenesis has been linked mutations in the receptor binding protein and the viral polymerase. Ferrets and mice are two important laboratory animal models for studying IAV pathogenesis. In 2009, a novel H1N1 subtype IAV (H1N1pdm) emerged in the human population and displayed variable pathology in humans. Using a mouse model, we show the variability of clinical isolates of H1N1pdm is driven by viral mutations, and that the timing of the inflammatory response is correlated with
disease severity. To investigate spatiotemporal aspects of potential host and viral contributions to influenza pathogenesis, we developed a live imaging platform for ferrets infected with a human clinical isolate of H1N1pdm. We detected an early recruitment of neutrophils into ferret lungs following infection, which accumulated at foci of H1N1pdm infection within specific anatomical regions of the lung by 24 hours post-infection. The neutrophil response was biphasic, characterized by the recruitment of two populations with differing gene expression profiles, and baseline neutrophil levels were increased throughout the entire lung, including areas with no apparent viral infection. Changes in the viral microenvironment resulted in the regeneration of lung epithelium during recovery phase of infection, and this was imaged with PET-CT using a radiolabeled glucose analog. In summary, these data illustrate critical features of the immune response to IAV, and emphasize important considerations about the timing and accuracy of innate immune responses in studying viral pathogenesis.

▼ Trauma patients who consumed
alcohol prior to sustaining injuries have higher rates of morbidity
and mortality than those with comparable injuries who did not
drink. Additionally, those who drank had impaired wound healing and
increased susceptibility to infection. Despite these clinical
observations, few studies have explored the effect of ethanol on
the innate immune cell function in a healing wound or how this may
alter resolution of cutaneous infection. A murine model of ethanol
and cutaneous wound infection was used to examine bacterial growth
and recruitment of innate immune cells. Mice were given either
ethanol (2.2 g/kg) or saline 30 minutes prior to being subjected to
six 3 mm dorsal punch wounds and Staphylococcus aureus (104
CFU/wound). At 24 hours after injury and infection, wound tissue
was collected. There was a 3.6 fold increase in bacterial growth in
the infected wounds of ethanol-exposed mice relative to those given
vehicle prior to wound infection. This elevated bacterial growth
was accompanied by an increase in the percentage of open wound area
realative to wounds from mice that were immediately sacrificed
after being injured (p<0.0001). To determine the contribution of
ethanol-related alterations in the innate immune response to this
heightened bacterial colonization, we examined wound neutrophil and
macrophage accumulation in the wounds by immunofluorescent imaging.
At 24 hours, no differences were observed in the number of
neutrophils at the infected wound site regardless of ethanol
exposure. In contrast, macrophage accumulation was 45% lower in
wounds from ethanol-exposed mice relative to vehicle-treated
animals (p<0.05). This decrease in macrophage recruitement was
accompanied by a 24% reduction in the level of macrophage
chemoattractant protein-1 (MCP-1) in wound homogenates from ethanol
exposed mice, however, this differences was not significant.
Consistent with the lack of change in the number of wound
neutrophils, we also failed to detect a difference in the wound
content of neutrophil chemokines, KC and macrophage inflammatory
protein-2 (MIP-2). To further explore differences in innate immune
response due to alcohol, we examined phagocytosis of S. aureus by
neutrophils and macrophages in the wound. However, no evidence of
phagocytosis by either cell was observed due to a lack of bacterial
dissemination into the tissue adjacent to the wound. Together,
these data show that ethanol impairs macrophage accumulation at the
infected wound site 24 hours after injury and suggest that the
reduction in these cells in ethanol-exposed mice could contribute
to reduced bacterial clearance and increased wound
size.

▼ In rabbits, antibody diversity
and B cell expansion are generated in gut-associated lymphoid
tissues (GALT), in an antigen- and T cell-independent mechanism,
and require interaction with intestinal microbiota. I investigated,
in vitro, the mechanism by which commensals drive GALT reactions.
Bacteria were isolated from the GALT of rabbits and identified by
16sRNA sequencing. I found that the commensals can bind to Ig,
independently of their specificity. In addition, a ~20kDa bacterial
molecule was immunoprecipitated with recombinant Ig molecules.
Stimulation of B cells with selected bacterial molecules induced
the activation of B cells. Stimulation of B cells through TLR2
induced the expression of chemokine receptors known to be expressed
on B cells as they move throughout the follicle. The data collected
in these studies support the idea that bacteria provide B cells
with signals that may lead to their activation and migration in
GALT, in an antigen independent
manner.

▼ T cell receptor (TCR) gene
modified T cells for adoptive T cell transfer therapy have been
shown to have clinical success in treating melanoma and other
malignancies by redirecting the specificity of peripheral blood
lymphocytes (PBL) to recognize tumor and/or viral associated
antigens of choice. One of the challenges in using TCR gene
modified T cells is the potential mispairing between endogenous and
introduced alpha and beta TCR chains, allowing for unwanted
off-target reactivity, autoimmunity, or impaired therapeutic
efficacy. One approach to augment proper TCR chain pairing and to
enhance T cell function involves the modification of the introduced
TCR genes to promote proper pairing. Our studies have demonstrated
that while certain modifications to a HCV NS3:1406-1415-reactive
TCR can augment properly paired introduced TCRs expressed on the
cell surface, this does not always correlate to increased T cell
function. A better understanding of how modifications to TCRs can
influence pairing and function will enhance our ability to improve
gene-modified T cells for adoptive
transfer.

▼ Introduction: Burn injury remains
a prominent clinical problem. Patients suffering from burns often
succumb to secondary infectious complications leading to sepsis and
widespread tissue injury ending in Multiple Organ Dysfunction.
However, the mechanism behind the onset of these extraneous
symptoms following burn injury is not fully understood. The
integrity of the gut barrier is of critical importance as it
harbors the largest bacterial reservoir in the body. Following burn
injury, we observed a breakdown of the gut barrier resulting in
increased gut leakiness and bacterial translocation. Under
homeostatic conditions, heat shock proteins (HSPs) stabilize tight
junction proteins. Particularly, HSP72 is shown to play a role in
stabilizing tight junctional complexes of the blood brain barrier.
Since tight junction proteins are responsible for maintaining gut
barrier integrity, we examined the effect of burn injury on the
heat shock response via HSPs and the claudin and occludin family of
tight junction proteins. Hypothesis: Burn injury
suppresses heat shock protein expression, which leads to
alterations in tight junction proteins contributing to increased
intestinal permeability and bacterial translocation after
injury. Methods: Male C57BL/6 (10-12 week old)
mice were anesthetized and administered an ~20% total body surface
area dorsal scald burn using 85⁰C water for ~7-9 seconds and
resuscitated with 1mL normal saline. The small and large intestines
were harvested 4 hours, one, and three days following burn injury
and processed for isolation of intestinal epithelial cells (IEC).
IEC HSP25, 72, and 90 mRNA expression was examined by q-RTPCR along
with claudin-4, claudin-8, and occludin. Protein levels of HSP25
and 72 and then claudin-4 and claudin-8 were examined by ELISA and
immunofluorescence staining respectively.
Results: We found significant decreases in HSP25, 72, and
90 expression (25%, 85%, and 51% respectively) in IECs harvested
from the small intestine one day post burn injury compared to sham
controls. This accompanied a significant decrease in claudin-4 and
-8 expression (54% and 49%) in small intestine IECs of burn animals
one day after burn compared to sham controls. At the protein level,
burn injury resulted in a decrease of 85% in HSP25 four hours after
burn injury and significant decreases in HSP72 four (51%) and three
days (46%) in small intestine IECs compared to sham controls. Upon
assessment of immunofluorescence staining of TJ proteins one day
after burn injury, we observed significant decreases in claudin-4
levels, but claudin-8 immunofluorescence staining is still in
progress. To discourage biases, we are currently expanding our
immunofluorescence staining of tight junction proteins to include
more tissue sections. Analysis of expression
HSP25, 72, and 90 in large intestine IECS one day after burn injury
resulted in a significant decrease in all three HSPs 4 hours of
44%, 79%, and 33% respectively after injury compared to sham. This
significant decrease in HSP72…

▼ The neonatal immune system is
functionally distinct from the adult immune system. Neonatal immune
responses are less reactive than their adult counterparts, and as
such, have an increased susceptibility to infection, resulting in
increased duration and severity of disease. There is evidence that
T-cells are partially responsible for the observed immunological
differences between neonates and adults. Murine studies on neonatal
immunity suggest that Th2 like responses predominate the neonatal
immune system, an observation not found in the adult immune system.
However, studies on human cord blood revealed that human neonates
do not exhibit elevated Th2 like cytokines (with the exception of
IL-13) when compared to adults, raising the question of whether or
not neonatal T-cells are fundamentally different from adult T-
cells. We sought to explore potential differences between neonatal
and adult T-cells through the comparative analysis of naïve CD4
T-cells derived from cord blood and adult peripheral blood. Our
data reveals that cord blood naïve CD4 T-cells have significantly
higher expression of CD26. Additionally, cord blood T-cells have a
greater capacity to produce Th1/Th2 cytokines than adult T-cells
when prompted to differentiate into effector cell types.
Additionally, undifferentiated naïve T-cells from cord blood are
less responsive to stimulation than adult T-cells, however this
decreased activity is likely not due to reduced expression of
signaling molecules in neonatal naive
T-cells.

▼ Mast cells are tissue resident, innate immune cells that provide protection against parasitic and bacterial infections and venom poisoning. Mast cells also play a pathogenic role in atopy and allergic diseases. Atopy and allergic diseases are increasing in the developed world and are predicted to continue to increase at an alarming rate. Current treatment options include corticosteroids, anti-histamines, anti-IgE and avoidance of allergen. These interventions have limitations: some patients are steroid resistant; anti-histamines have low efficacy since they need to be administered early during allergen exposure; and anti-IgE is costly. Thus there is a clinical need for new treatment options. An efficient approach is to re-purpose FDA-approved drugs. Selective serotonin reuptake inhibitors (SSRIs) are a class of anti-depressants used to treat depression and other psychiatric disorders. SSRIs have been shown to possess anti-inflammatory properties, but the mechanism of action is unclear. The possibility to treat allergic diseases with SSRIs has not been studied. Using primary mouse bone marrow derived,
ex vivo cultured mouse peritoneal, and primary skin derived human mast cells, we show that the SSRI fluoxetine suppresses IgE-mediated degranulation, cytokine production, and inflammatory lipid secretion. Several other SSRIs showed similar effects on mouse mast cells. Cytokine suppression occurs at a transcriptional level, as evidenced by decreased signaling downstream of the IgE receptor and reduced cytokine mRNA induction. We found that fluoxetine-mediated suppression requires the purinergic receptor, P2X3. Furthermore, we show that IgE stimulation elicits rapid ATP release from mast cells, and that ATP and purinergic signaling is a positive feedback regulator of mast cell activation. Fluoxetine can also suppress ATP-mediated cytokine production, degranulation, and lipid production most likely via NFkb suppression and diminished purinergic receptor expression. Importantly, fluoxetine effects are consistent in an
in vivo passive systemic anaphylaxis (PSA) model and in a house dust mite (HDM) airway hyperresponsiveness and lung inflammation model of asthma. In the PSA model, fluoxetine reduced hypothermia and cytokine production. In the asthma model, the drug suppressed bronchoresponsiveness as well as pulmonary mast cell hyperplasia and eosinophilia, and the recruitment of Th2 cells, neutrophils, eosinophils, and lymphocytes to the bronchoalveolar space, as well as cytokine levels in the bronchoalveolar fluid in sensitized mice. Overall, we show that fluoxetine broadly suppresses mast cell activation
in vitro and
in vivo, most likely by impeding an ATP-P2X3 positive feedback loop.

▼ Gastro-intestinal (GI) tract harbors largest number of microbiota as well as the largest number of immune cells for a given tissue. The host needs to mount an effective immune response against invading pathogens and tolerance against commensals. Thus, regulatory mechanism and barrier function of the GI tract are of utmost importance for appropriate host microbe interaction and gut homeostasis. Intestinal epithelial cells (IECs) act as the first line of defense against invading pathogens. IECs recognize pathogens and commensals and mount an effective innate immune response. Such recognition of pathogens is mediated through germ line encoded pattern recognition receptors (PRRs). Intestinal sub-epithelial myofibroblasts (ISEMFs) reside just beneath the surface epithelium and are involved in maturation and differentiation of epithelium. ISEMFs protect from pathogens that breach surface epithelium by expressing PRRs. Lack of stable intestinal epithelial and sub-epithelial myofibroblast cell lines has slowed down scientific studies on these cells. In this study, we established and characterized ISEMF cells from the ileum of a 2-day old calf. We also had generated stable bovine ileal epithelial cell (BIEC-c4) cultures in our lab. On real time-quantitative polymerase chain reaction (RT-qPCR) analysis both these cell types expressed Toll-like receptors (TLRs) 1-9. To investigate their responses to various pathogen-associated molecular patterns (PAMPs), we stimulated both cell types for 3 hours and 24 hours with various PAMPs. The RT-qPCR assay was used to investigate changes in TLR gene expression and in cytokine genes following stimulation. Lipopolysaccharide, peptidoglycan, and flagellin were used as bacterial ligands of surface PRRs. Similarly, γ-D-Glu-mDAP, muramyl dipeptide, polyinosonic:polycytidylic acid, poly I:C complexed with lyovec, and imiquimod were used as ligands of cytosolic and endosomal PRRs. Bovine ileal ISEMFs responded to bacterial PAMPs and to ligands of cytosolic and endosomal PRRs by significantly altering TLR gene expression. Unlike bovine ISEMFs, BIEC-c4 cells responded only to bacterial ligands. Thus, we conclude that bovine ileal ISEMF can be a good model to study innate immune responses and signaling pathways occurring at subepithelial compartment. However, BIEC-c4 cells may serve as a good in-vitro model to study enteric
infectious disease pathogenesis and innate immune responses associated with them.

▼ It is known that the elderly are
more susceptible to illnesses and infections and respond poorly to
immunization. A contributing factor to a decrease in the immune
response in the elderly is the decline in the production of naïve T
cell by the thymus. In the thymus, the notch receptor expressed on
early T cell progenitors (ETP) binds to its ligand expressed on
thymic epithelial cells (TEC), signaling ETP to develop through a
series of developmental stages before maturing into naive T cells.
Because ETP are non-self renewing, the thymus relies on the bone
marrow (BM) for a continuous supply of T cell progenitors to
generate and maintain the peripheral T cell pool. With age, the
numbers of TEC, ETP, as well as the number of T cell progenitors in
the BM are reduced, contributing to the decline in the production
of naïve T cells. Previously, our lab has shown that with age, the
decline in the number of thymocytes correlates with the decline in
the expression of Foxn1 in thymic stroma. Foxn1 is a transcription
factor critical for functional maturation of TEC and thymic
organogenesis. Mutations in Foxn1 result in the nude phenotype
characterized by hairless and athymic conditions. Interestingly,
nude mice also have defects in the BM, suggesting a role for Foxn1
in hematopoiesis. A Foxn1Tg mouse model was developed in which
Foxn1 is over expressed in thymus and in the BM. I showed that aged
Foxn1Tg mice have a higher number of TEC, and ETP; consequently,
leading to attenuation of the age-associated decline in
thymopoiesis. In addition, the decline in the number of bone
marrow-derived T cell progenitors is prevented in Foxn1Tg. Using
adaptive transfer experiments, I demonstrated that the aged Foxn1Tg
BM microenvironment promotes the development of T cell progenitors.
Lastly, I have identified a novel population of cells in the BM
that express Foxn1. Taken together this data suggests that the
presence of Foxn1 expressing cells in the thymus and BM contribute
to niches that play an important role in the maintenance of T cell
progenitors with age.

▼ Adoptive cell transfer (ACT)
using T cells engineered to express tumor-specific T cell receptors
(TCR) holds great promise in treating cancer patients. ACT involves
the in vitro generation of large numbers of tumor-specific T cells,
which are then administered back to the patient, to establish an in
vivo response and effective tumor control. Our lab conducted a
phase I clinical trial in which metastatic melanoma patients
received systemic infusions of autologous T cells transduced to
express a tyrosinase-specific TCR (TIL 1383I). We observed tumor
regression in one of seven patients and the development of
vitiligo, indicative of T cell-mediated killing of melanocytes, in
two of seven patients. Our findings demonstrate that the ACT of TCR
gene-modified T cells has the potential to eliminate tumors, but
the modest number of patients responding to therapy emphasizes the
need for improvement. In the studies presented in this
dissertation, we evaluated the intratumoral delivery of TIL 1383I
TCR transduced T cells in a widely used B16 mouse melanoma model.
We employed an alternative strategy and expressed the TIL 1383I TCR
on allogeneic, as opposed to syngeneic, donor T cells, to attempt
to counteract the suppressive tumor microenvironment. We
demonstrated that intratumoral treatment with TIL 1383I TCR
allogeneic T cells extended survival and suppressed tumor growth in
mice more effectively than treatment with TIL 1383I TCR syngeneic T
cells. Tumors treated with TIL 1383I TCR allogeneic T cells
exhibited greater accumulation of antigen cross-presenting
dendritic cell subsets, as well as increased T cell activation, in
the tumor and tumor draining lymph nodes. TIL 1383I TCR allogeneic
T cell treatment generated endogenous tumor-specific T cells that
prevented the development of distant, untreated tumors.
Furthermore, the addition of immune checkpoint inhibitors promoted
tumor clearance and enhanced protection in mice treated with TIL
1383I TCR allogeneic T cells. Intratumoral delivery of allogeneic
TCR gene-modified T cells can improve clinical responses and expand
the available tumor antigen targets, without compromising safety,
by avoiding systemic
administration.

▼ Community-acquired Methicillin-resistant
Staphylococcus aureus (CA-MRSA) strain USA300 is a major cause of invasive drug-resistant skin and soft tissue infections in humans. Although
S. aureus is a well-recognized extracellular pathogen, recent reports that USA300 survives inside host macrophages suggest that the intramacrophage environment may be a niche for persistent infection. Intramacrophage survival requires bacteria to avoid destruction in the phagosome; however, mechanisms by which USA300 evades phagosomal defenses are unclear. We examined the fate of the USA300-containing phagosome in human THP-1 macrophages by evaluating phagosomal acidification and maturation, and by testing the impact of phagosomal conditions on bacterial viability. Utilizing confocal microscopy, we discovered that the USA300-containing phagosome acidified rapidly, and colocalized with the late endosome and lysosome protein LAMP-1. Interestingly, significantly fewer phagosomes containing live USA300 associated with lysosomal hydrolyses cathepsin D and β-glucuronidase than those containing dead bacteria, suggesting that USA300 harbors the ability to perturb lysosomal fusion during macrophage infection. We then examined the impact of phagosomal acidification on USA300 intracellular viability and found that inhibition of acidification significantly impairs USA300 survival, as well as negatively impacts virulence gene regulator
agr expression. Together, these results suggest that USA300 survives inside macrophages by altering phagolysosome formation, as well as relying on vacuolar acidification as a trigger for virulence.
