Understanding The Role Of Androgen Receptor Signaling In Modulating P38-Alpha Mitogen-Activated Protein Kinase In Experimental Autoimmune Encephalomyelitis, Grace Kathryn Voorhees

Multiple Sclerosis (MS) is an inflammatory autoimmune disease of the central nervous system, characterized by axonal demyelination and multifocal inflammation. Like many autoimmune diseases, it is a sexually dimorphic disease, being 3-4 times more common in females than in males. p38α MAP kinase (MAPK) has an integral role in modulating inflammatory processes in autoimmunity. Conditionally ablating p38α MAPK in myeloid cells in B6 mice shows a sex difference in the animal model of MS, experimental autoimmune encephalomyelitis (EAE). In the absence of sex hormones, this sex difference was reversed, suggesting a role for sex hormones in modulating p38α MAPK signaling …

Semi-invariant natural killer T (iNKT) cells are critical components of the host immune response in peripheral tissues such as the lung, liver, and gut, and they play important roles in cancer, bacterial infections, autoimmunity, wound repair, and atherosclerosis. Tissue-resident iNKT cells exert their effects early in the developing immune response by rapidly producing a wide variety of cytokines and chemokines, and it was recently discovered that different tissues possess iNKT cell subsets that preferentially produce IFN-γ (NKT1), IL-4 (NKT2), or IL-17 (NKT17). Despite their critical role in the immune response, the mechanisms that regulate iNKT cell function in the periphery …
The Contribution Of Metabolism To The Regulation Of Caspase Activity And Cell Death In T Lymphocytes, Michael Anthony Secinaro
The Contribution Of Metabolism To The Regulation Of Caspase Activity And Cell Death In T Lymphocytes, Michael Anthony Secinaro

During an immune response, T cell activation is mirrored by a dramatic metabolic shift from oxidative phosphorylation to glycolysis. The upregulation of glycolysis allows the cell to generate the molecules needed to rapidly proliferate and to synthesize effector molecules. The resolution of the T cell response is characterized by equally fast death of most effector T cells. The remaining T cells shift back to oxidative phosphorylation, allowing the cell to survive as a memory T cell. The upregulation of glycolysis and proliferation during the effector phase is paralleled by an increased sensitivity to T cell receptor restimulation-induced cell death (RICD). …
