Il-27 Negatively Impacts Immunity Developed Following Bcg Administration, Shelby D. Bradford
Graduate Theses, Dissertations, and Problem Reports
Mycobacterium tuberculosis (Mtb) is the causative agent of tuberculosis (TB), a predominantly respiratory pathogen responsible for over ten million infections and one million deaths last year. Despite it being a primary objective of the World Health Organization (WHO) for several decades to irradicate TB, progress toward this objective has fallen short of the 2020 target to end TB by 2035. Meeting this goal will require advancements in diagnostic tools, education, healthcare access, and treatments and preventatives. Regarding prevention, the primary tool for this strategy is through vaccination. Currently, the only licensed vaccine for protection against TB is the century old …
Regulation Of Gut Commensal-Specific T Cell Differentiation By Dendritic Cell Subsets, Emilie Russler-Germain
Regulation Of Gut Commensal-Specific T Cell Differentiation By Dendritic Cell Subsets, Emilie Russler-Germain
Arts & Sciences Electronic Theses and Dissertations
The mammalian gastrointestinal tract can harbor both beneficial commensal organisms important for host health, but also pathogenic organisms capable of intestinal damage. It is therefore important that the host immune system mounts appropriate responses to different intestinal organisms – promoting tolerance to some, controlling the colonization of others, and inducing sterilizing immunity in cases of noxious pathogens. Failure to induce tolerance to commensal organisms may underlie immune-mediated diseases such as human inflammatory bowel disease, while inappropriate tolerance to more harmful organisms has the potential to result in infection, inflammation, or even malabsorption. Adaptive immune responses to intestinal commensal organisms are …
T Cell Immunity In Pancreatic Cancer Is Undermined By Dendritic Cell Dysfunction, Samarth Hegde
T Cell Immunity In Pancreatic Cancer Is Undermined By Dendritic Cell Dysfunction, Samarth Hegde
Arts & Sciences Electronic Theses and Dissertations
Pancreatic cancer carries a dismal prognosis, and desperately needs viable therapeutic interventions beyond chemo-radiation. T cell-dependent immunotherapies have shown great promise in several tumor types, but have not been effective for the vast majority of pancreatic cancer patients. This is, in part, due to our limited understanding of how antigenicity of pancreatic lesions is recognized, and how adaptive immunity is overcome in this disease. We sought to study tumor-immune interactions and identify mechanisms for this immune-failure using several spontaneous and unperturbed mouse models of pancreatic adenocarcinoma. We found that early pancreatic lesions fail to elicit tumor-limiting CD4+ TH1 and CD8+ …
Immunobiology Of The Mucosal Response To Helicobacter Pylori In Children, Kyle Brawner
Immunobiology Of The Mucosal Response To Helicobacter Pylori In Children, Kyle Brawner
All ETDs from UAB
Helicobacter pylori colonizes the stomach of approximately one half of the world’s population. However, the vast majority of infected persons remain asymptomatic. The degree of H. pylori-induced gastric inflammation depends on a complex interaction of several factors. In this dissertation, we focus on age as a determinant of gastritis severity. Children are known to respond to H. pylori infection with a stronger T regulatory cell profile compared with infected adults, yet the reason remains unknown. The influence of the microbiota on, and the communication among, cells of the innate immune system shape the nature of the adaptive immune response to …
