Multiple autoimmune-associated variants confer decreased IL-2R signaling in CD4+ CD25(hi) T cells of type 1 diabetic and multiple sclerosis patients.
IL-2 receptor (IL-2R) signaling is essential for optimal stability and function of CD4(+)CD25(hi)FOXP3(+) regulatory T cells (Treg); a cell type that plays an integral role in maintaining tolerance.Thus, we hypothesized that decreased response to IL-2 may be a common phenotype of subjects who have autoimmune diseases associated with variants in the
