The Impact Of Nitric Oxide On Dendritic Cell Metabolism, Julia Priscilla Snyder
Graduate College Dissertations and Theses
Dendritic cells (DCs) are sentinel immune cells capable of directly sensing and responding to pathogens. Upon pathogen recognition, DCs undergo a process of activation that allows them to participate in the proinflammatory response at the site of infection and to initiate the adaptive immune response through antigen presentation to T cells. Because activated DCs serve as the critical link between innate and adaptive immunity, modulating DC activation could be a powerful tool in various clinical contexts such as vaccine design. DC activation is accompanied by widespread changes in metabolism including the rapid upregulation of glycolysis, which is sustained in DCs …

The Contribution Of Metabolism To The Regulation Of Caspase Activity And Cell Death In T Lymphocytes, Michael Anthony Secinaro
Graduate College Dissertations and Theses
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). …
