Examining The Ligands, Location, And Function Of Toll-Like Receptor 10, Kiefer Keanu Tam

Master's Theses

Toll-like receptors are a class of innate immune pattern recognition receptors that detect pathogen-associated molecular patterns and regulate downstream inflammatory responses. Toll-like receptor 10 remains the only human TLR whose ligand specificity, cellular localization, and immunological function are not fully defined. Emerging evidence suggests that TLR10 may play an anti-inflammatory role and can heterodimerize with TLR2 to modulate immune signaling. Previous studies from our laboratory demonstrated that stimulation with heat-killed Mycobacterium tuberculosis promotes TLR2-TLR10 heterodimerization and trafficking to the cell surface. In this study, we expanded our ligand panel to include additional gram-positive bacteria, particularly anti-inflammatory probiotic species, to further …

Impact Of Inhibiting Mitochondrial Calcium Uptake On Calcium Homeostasis And Postmortem Metabolism In Porcine Muscle, Fatema Rahaman Mishu

All Graduate Theses and Dissertations, Fall 2023 to Present

After harvesting the animal, pork muscle continues to undergo changes as it turns from muscle into meat. During this early period, the muscle uses up energy and produces acid, which lowers pH and can affect important quality traits such as color and how well the meat holds water. A key driver of these early changes is calcium, a natural mineral inside muscle cells that helps control contraction and energy use. In this study, we tested whether mitochondria (the cell’s “powerhouse”) help control calcium after harvest and, in turn, influence early postmortem changes in pork. We used a research compound (DS16570511) …
