The role of Eros in Innate and Adaptive Immunity (360G-Wellcome-206617_Z_17_A)
I will investigate the role of a novel protein, Eros, in immunity. I discovered the fundamental importance of this protein by demonstrating that Eros-deficient mice die from Salmonella infection because their phagocytes cannot make reactive oxygen species. This is because Eros is essential for expression of vital components of the phagocyte NADPH oxidase. My work represents the only paper on this protein. I have found that Eros-deficiency has effects that go far beyond the generation of reactive oxygen species. In particular: Eros regulates the expression of other key macrophage proteins including P2X7, a key activator of the NLRP3 inflammasome Eros regulates the expression of numerous cytokines from CD4+ T cells. Eros -/- T cells make 10-fold more IL-4 than control cells In mouse and human systems, I will investigate the molecular mechanisms by which Eros: controls the abundance of a subset of proteins working on the hypothesis that it is a novel component of the protein quality control pathway using structural, biochemical and cell biological techniques. controls T cell cytokine secretion. I will spend time working with John O'Shea, a world leader in this field.
