The Immunoregulation Of Autoimmune Diabetes, Hao Hu

Arts & Sciences Electronic Theses and Dissertations

How autoimmune diseases are regulated is a long-term research topic in the autoimmunity field. We use autoimmune diabetes as a model to study this. Autoimmune diabetes is a T cell-dependent autoimmune syndrome. The functions of T cells are regulated during their development and activation. Developmentally, T cells will undergo a stringent thymic selection: a process that self-reactive T cells are tolerized to become thymic derived Tregs or can be deleted by apoptosis based on binding affinity and avidity between the TCRs and self-peptide:MHC complexes. After T cells mature, they can also be tolerized in the periphery in many other ways, …
