CD278 (ICOS) belongs to the CD28 and CTLA-4 cell-surface receptor family. It forms homodimers (47-57kD) and enhances all basic T cell responses to a foreign antigen, specifically proliferation, secretion of lymphokines, up-regulation of molecules that mediate cell-cell interaction, and effective help for antibody secretion by B cells. ICOS signaling is also an important regulator for T cell homeostasis. ICOS plays a role in humoral immune response and is thought to have involvement in the development of Th2 cells and to play a protective role in inflammatory autoimmune diseases.
