B Cells In The Gut Associated Lymphoid Tissue (Galt), Ameera Bukhari
B Cells In The Gut Associated Lymphoid Tissue (Galt), Ameera Bukhari
Dissertations
The gut-associated lymphoid tissue (GALT) is the largest mass of lymphoid tissue in the body, and it is a unique line of defense where immune cells are in constant contact with gut commensals and pathogens. B lymphocytes constitute most of the lymphatic tissues of the gastrointestinal (GI) tract and they play a critical role in protecting from infections, promoting tolerance, and shaping microbiota in the gut through the production of immunoglobulins (Ig). Previous studies on GALT B cells in human showed that large B cell clones in the body partition into two broad networks: one includes the blood, bone marrow, …
Phenotypic Analysis Of Murine Gut Associated Lymphocytes, Madison Flood
Phenotypic Analysis Of Murine Gut Associated Lymphocytes, Madison Flood
Master's Theses
γδ T cells are important in the role of immune homeostasis, especially in relation to the gut. It has been shown that there is a higher proportion of γδ T cells in the intestines than in circulation. With this knowledge, our lab focused on understanding the mechanisms of these cells, specifically regarding immune tolerance. In our preliminary research, we identified a subset of γδ T cells that express Foxp3, a transcription factor essential for the functioning of regulatory T cells, in the neonatal (5 day old) intestine. We hypothesized that these Foxp3+ γδ T cells have immunosuppressive functions upon exposure …
Escherichia Coli And Salmonella Sp. In Domestic Cattle And Wild Roosevelt Elk: Fecal Pathogens At The Wildlife-Domestic Interface, Emily A. Buck
Escherichia Coli And Salmonella Sp. In Domestic Cattle And Wild Roosevelt Elk: Fecal Pathogens At The Wildlife-Domestic Interface, Emily A. Buck
Cal Poly Humboldt theses and projects
Direct or indirect contact between domestic populations of animals and wildlife carries an inherent risk for transmission of pathogens that cause infectious disease. In Humboldt and Del Norte counties of northern California, ongoing conflict between ranchers and Roosevelt elk groups results from elk use of ranching pastures and pastures on private land. Fecal samples from elk in association with cattle, cattle, and from elk not in known association with cattle were assessed for the presence of bacteria Salmonella enterica and pathogenic Escherichia coli to assess whether association with cattle increases risk of infection for elk. Group identity (one of the …

Immunotherapies such as checkpoint blockade therapies are known to enhance anti-melanoma CD8+ T cell immunity, but only a fraction of patients treated with these therapies achieve durable immune response and disease control. It may be that CD8+ T cells need help from other immune cells to generate effective and long-lasting anti-tumor immunity or that CD8+ T cells alone are insufficient for complete tumor regression and cure. Melanoma contains significant numbers of B cells; however, the role of B cells in anti-melanoma immunity is controversial. In this study, B16 melanoma mouse models were used to determine the role of B cells …

Allergic asthma is a chronic inflammatory respiratory disease associated with eosinophilic infiltration, increased mucus production, airway hyperresponsiveness, and airway remodeling. Epidemiologic data reveal that the prevalence of allergic sensitization and associated diseases has increased in the twentieth century. This has been hypothesized to be partly due to reduced contact with microbial organisms (the hygiene hypothesis) in industrialized society. Airway epithelial cells, once considered a static physical barrier between the body and the external world, are now widely recognized as immunologically active cells that can initiate, maintain, and restrain inflammatory responses, such as those that mediate allergic disease. Airway epithelial cells …

BACKGROUND: Neoadjuvant checkpoint inhibition (CPI) has recently demonstrated impressive outcomes in patients with stage 3 cutaneous melanoma. However, the safety, efficacy, and outcome of neoadjuvant CPI in patients with mucosal melanoma (MM) are not well studied as MM is a rare melanoma subtype. CPI such as combination nivolumab and ipilimumab achieves response rates of 37-43% in unresectable or metastatic MM but there is limited data regarding the efficacy of these agents in the preoperative setting. We hypothesize that neoadjuvant CPI is a safe and feasible approach for patients with resectable MM.
METHOD: Under an institutionally approved protocol, we identified adult …

Biological Sciences Faculty Publications
Bacterial endosymbionts are abundantly found in both hard and soft ticks. Occidentia massiliensis, a rickettsial endosymbiont, was first identified in the soft tick Ornithodoros sonrai collected from Senegal and later was identified in a hard tick Africaniella transversale. In this study, we noted the presence of Occidentia species, designated as Occidentia-like species, in a soft tick O. turicata americanus. Sequencing and phylogenetic analyses of the two genetic markers, 16S rRNA and groEL confirmed the presence of Occidentia-like species in O. turicata americanus ticks. The Occidentia-like species was noted to be present in all developmental stages …
Evaluation Of Ivermectin Antiviral Activity Against Avian Infectious Bronchitis Virus Using A Chicken Embryo Model, Donald L. Reynolds, E. Barry Simpson
Evaluation Of Ivermectin Antiviral Activity Against Avian Infectious Bronchitis Virus Using A Chicken Embryo Model, Donald L. Reynolds, E. Barry Simpson
School of Veterinary and Biomedical Sciences: Faculty Publications
Ivermectin is widely used in both animals and humans as an FDA-approved parasiticide. Ivermectin has also been reported to have antiviral activity against several viruses including coronaviruses. There are reports that indicate ivermectin may have some role in diminishing the disease caused by SARS-CoV-2, but the evidence is inconclusive. The objective of this study was to determine if ivermectin was efficacious in inhibiting avian infectious bronchitis virus (IBV, a coronavirus) replication in chicken embryos. Briefly, our approach was to use the Massachusetts vaccine strain of IBV in combination with various doses of ivermectin and then inoculate these preparations into chicken …

School of Veterinary and Biomedical Sciences: Faculty Publications
In the last 15 years, crustacean fisheries have experienced billions of dollars in economic losses, primarily due to viral diseases caused by such pathogens as white spot syndrome virus (WSSV) in the Pacific white shrimp Litopenaeus vannamei and Asian tiger shrimp Penaeus monodon. To date, no effective measures are available to prevent or control disease outbreaks in these animals, despite their economic importance. Recently, double-stranded RNA-based vaccines have been shown to provide specific and robust protection against WSSV infection in cultured shrimp. However, the limited stability of double-stranded RNA is the most significant hurdle for the field application of these …

The 1990s saw the rapid reemergence of malaria in Amazonia, where it remains an important public health priority in South America. The Amazonian International Center of Excellence in Malaria Research (ICEMR) was designed to take a multidisciplinary approach toward identifying novel malaria control and elimination strategies. Based on geographically and epidemiologically distinct sites in the Northeastern Peruvian and Western Brazilian Amazon regions, synergistic projects integrate malaria epidemiology, vector biology, and immunology. The Amazonian ICEMR’s overarching goal is to understand how human behavior and other sociodemographic features of human reservoirs of transmission— predominantly asymptomatically parasitemic people—interact with the major Amazonian malaria …

Diversity And Phylogenetic Relationships Of ‘Tetraphyllidean’ Clade 3 (Cestoda) Based On New Material From Orectolobiform Sharks In Australia And Taiwan, Janine N. Caira, Kirsten Jensen
Harold W. Manter Laboratory of Parasitology: Library Materials
In an effort to expand knowledge of Clade 3—one of the ten clades that compose the non-monophyletic order ‘Tetraphyllidea’ all current members of which parasitise orectolobiform sharks—we targeted species of orectolobiform sharks that had not previously been examined for ‘tetraphyllidean’ cestodes. That work led to the discovery of three new species off Australia and Taiwan. Ambitalveolus gen. n. was erected to accommodate these species. Ambitalveolus costelloae gen. n. et sp. n., Ambitalveolus kempi sp. n., and Ambitalveolus penghuensis sp. n. differ from one another in scolex size, genital pore position, and number of marginal loculi, proglottids, and testes. Among ‘tetraphyllideans’, …

Circling The Drain: The Extinction Crisis And The Future Of Humanity, Rodolfo Dirzo, Gerardo Ceballos, Paul R. Ehrlich
Harold W. Manter Laboratory of Parasitology: Library Materials
Humanity has triggered the sixth mass extinction episode since the beginning of the Phanerozoic. The complexity of this extinction crisis is centered on the intersection of two complex adaptive systems: human culture and ecosystem functioning, although the significance of this intersection is not properly appreciated. Human beings are part of biodiversity and elements in a global ecosystem. Civilization, and perhaps even the fate of our species, is utterly dependent on that ecosystem’s proper functioning, which society is increasingly degrading. The crisis seems rooted in three factors. First, relatively few people globally are aware of its existence. Second, most people who …
Profiling Durable Anti-Tumor Memory T Cell Responses In Long-Term Melanoma Survivors, Jichang Han
Profiling Durable Anti-Tumor Memory T Cell Responses In Long-Term Melanoma Survivors, Jichang Han
Dartmouth College Ph.D Dissertations
While T-cell responses to cancer immunotherapy have been avidly studied,
long-lived memory has been poorly characterized. Of melanoma patients who
receive immunotherapy, long-term survivors are frequently found to develop
melanoma-associated vitiligo. Our prior work showed in a preclinical model that
vitiligo skin sustained a long-lived CD8+ resident memory T cell (TRM) population,
playing key roles in perpetuating anti-tumor immunity. However, the characteristics
and longevity of these memory T cells in melanoma survivors have not been defined.
In the present studies, we probed both the CD8+ and CD4+ T cell responses,
focusing on memory T cell responses in a cohort of …

Bone Morphogenetic Proteins Shape TReg Cells, Piotr Kraj
Bone Morphogenetic Proteins Shape TReg Cells, Piotr Kraj
Biological Sciences Faculty Publications
The transforming growth factor-β (TGF-β) family includes cytokines controlling cell behavior, differentiation and homeostasis of various tissues including components of the immune system. Despite well recognized importance of TGF-β in controlling T cell functions, the immunomodulatory roles of many other members of the TGF-β cytokine family, especially bone morphogenetic proteins (BMPs), start to emerge. Bone Morphogenic Protein Receptor 1α (BMPR1α) is upregulated by activated effector and Foxp3+ regulatory CD4+ T cells (Treg cells) and modulates functions of both of these cell types. BMPR1α inhibits generation of proinflammatory Th17 cells and sustains peripheral Treg cells. This finding underscores the importance of …
A Post-Pneumonia Epizootic Evaluation Of The Rapid City, South Dakota Bighorn Sheep Herd, Amanda N. Ensrud
A Post-Pneumonia Epizootic Evaluation Of The Rapid City, South Dakota Bighorn Sheep Herd, Amanda N. Ensrud
Electronic Theses and Dissertations
Pneumonia is a major factor affecting populations of free-ranging bighorn sheep (Ovis canadensis) across western North America. Pneumonia can occur in large-scale epizootics, during which greater than half of the population typically dies. After these epizootics, surviving ewes continue to conceive and bear lambs. However, lamb recruitment may remain low due to periodic or annual pneumonia outbreaks causing high lamb mortality rates, sometimes greater than 90%. Our study focused on the Rapid City, South Dakota bighorn sheep (BHS) herd that has recorded pneumonia-induced population decline since 2009. The first objective was to improve lamb health and survival by identifying and …

Diarrheal disease, still a major cause of childhood illness, is caused by numerous, diverse infectious microorganisms, which are differentially sensitive to environmental conditions. Enteropathogen‐specific impacts of climate remain underexplored. Results from 15 studies that diagnosed enteropathogens in 64,788 stool samples from 20,760 children in 19 countries were combined. Infection status for 10 common enteropathogens—adenovirus, astrovirus, norovirus, rotavirus, sapovirus, Campylobacter, ETEC, Shigella, Cryptosporidium and Giardia—was matched by date with hydrometeorological variables from a global Earth observation dataset—precipitation and runoff volume, humidity, soil moisture, solar radiation, air pressure, temperature, and wind speed. Models were fitted for each pathogen, accounting …

Tuberculosis (TB) kills more people each year than any infectious disease worldwide with recent exception of SARS-CoV-2. Though the Bacille Calmette Guerin (BCG) vaccine confers protection against severe extrapulmonary forms of TB, there is no licensed vaccine for the prevention of pulmonary tuberculosis. The strongest correlate of protection against pulmonary tuberculosis is Th1/Th17 biased cell mediated immunity. Several candidates for TB vaccine adjuvants have shown Th1/Th17 polarizing capacity in clinical trials including Mincle agonist trehalose dibehenate (TDB) and TLR4 agonist monophosphoryl lipid A (MPL). Furthermore, combinatorial administration of MPL and TDB formulated in dimethyldioctadecylammonium (DDA) liposomes has been previously reported …
The Combination Of Tlr7/8 And Tlr4 Adjuvants In An Influenza Vaccine Produce Unique Antigen-Specific Adaptive Immunity And Protect Against Lethal Heterologous Influenza Challenge, Shelby Lynn Cole
Graduate Student Theses, Dissertations, & Professional Papers
Influenza virus infection is a global health concern resulting in death and illness each year, which disproportionally effects high-risk individuals. While there are several approved vaccines for seasonal influenza, there are some limitations to consider: current vaccines provide minimal cross protection against seasonally drifted influenza subtypes, influenza vaccine strains change each year, requiring timely manufacture of a new vaccine. Thus, vaccines capable of inducing a more robust and broadly protective immune response to multiple influenza subtypes remains a critical unmet need. Adjuvants and novel delivery systems are an interesting and promising avenue of exploration for enhancing and broadening seasonal influenza …

Makara Journal of Science
The number of tuberculosis (TB) cases worldwide reached 1.5 million in 2018; thus, TB is considered a deadly disease. TB is caused by Mycobacterium tuberculosis and involves lipid synthesis. Considering the importance of lipid metabolism in bacteria, FabH may be an essential protein target for repressing lipid synthesis. Capsaicinoids from Capsicum annuum demonstrate potent antibacterial activity. This study predicted the ability of capsaicinoid compounds to inhibit FabH. In silico analysis was performed by retrieving the structure of FabH from PDB and those of selected capsaicinoid derivatives from PubChem. The compounds were docked using AutoDock Vina in PyRx 0.8 software. The …

HPV is the most common sexually transmitted infection. It is estimated that 80% of sexually active adults will contract an HPV infection. Thus, there is a significant need for low-cost and easily distributable HPV antivirals that can be used alongside vaccines to combat infection. Herein I have identified protamine sulfate (PS) as a potent microbicide against HPV infection. PS was agnostic to genotype and efficacious pre and post HPV exposure. PS application topically reduced HPV internalization by altering epidermal growth factor receptor (EGFR) signaling and suppressed EGFR-stimulated HPV entry. Our preliminary data also suggest that heparin binding epidermal growth factor …

The significant challenge towards a successful HIV cure lies in eradicating persistent viral reservoirs across diverse tissue niches. As a result, HIV-infected individuals have to resort to lifelong antiretroviral therapy. Recent news of supposed HIV eradication in a second patient has further re-invigorated the fields of HIV cure. However, a few barriers remain, such as the lack of currently available assays to accurately quantify viral reservoirs, limited information on cellular factors associated with persistence, and varied dynamics of the viral reservoir in various body compartments. Lastly, HIV-infected individuals live different lifestyles stemming from comorbid substance abuse including consumption of morphine, …

KGI Theses and Dissertations
Intrinsically disordered proteins (IDPs) and IDP regions (IDPRs) fail to form stable structures but have important biological functions via interacting with various molecular partners (proteins, DNA, RNA, glycosaminoglycans). We hypothesized that IDPRs are potential targets for therapeutics development because they are reservoirs of evolutionary innovation, and they play crucial roles in adaptation to pathogens.
We first studied the evolution of IDPRs in the human proteome and compared it with the proteome of non-human primates. We have found that evolutionary young protein-coding genes have included low conserved regions in the N-terminal part of proteins, and such regions are linked to high …

Recent studies have demonstrated that embryonic stem cells (ESCs) are deficient in expressing type I interferons (IFN), the cytokines that play key roles in antiviral responses. However, the underlying molecular mechanisms and biological implications of this finding are poorly understood. In this study, I used a synthetic RNA-based assay that can simultaneously assess multiple forms of antiviral responses in ESCs. Dicer is an enzyme essential for RNA interference (RNAi), which is used as a major antiviral mechanism in invertebrates but not clear in vertebrates. RNAi activity is detected in wild-type ESCs but is abolished in Dicer knockout ESCs (D−/−ESCs) as …

Like humans, outbred Sprague-Dawley CD rats exhibit a polygenic pattern of inheritance of the obese phenotype and not all individuals exposed to a high calorie intake develop obesity. We hypothesized that differences in gut microbiota composition account for phenotype differences between obese prone (OP) and obese resistant (OR) rats. We studied the gut microbiota composition of OPand OR rats after a high fat (HF) diet and how they respond to fermentation of resistant starch (RS). In phase 1 of the study 28 OP and 28 OR rats were fed a HF diet. In order to determine causal role of microbiota …
