Islet allografts are subject to alloimmune and autoimmune destruction when transplanted into autoimmune prone animals or humans. The ICOS-B7h pathway plays a role in alloimmune responses, but its function in autoimmunity against islet cells is controversial. We investigated the role of ICOS signaling in autoimmune and alloimmune responses in NOD mice. ICOS blockade prevents development of spontaneous disease in pre-diabetic NOD mice. Furthermore, while ICOS blockade prolongs graft survival in a fully mismatched non-autoimmune islet allograft model in C57BL/6 recipients, it has no beneficial effect in reversing diabetes in models of islet transplantation in NOD mice involving autoimmunity alone or both allo- and autoimmunity. Interestingly, ICOS blockade is effective in prolonging heart allograft (not subject to tissue-specific autoimmunity) survival in NOD mice. We conclude that in islet transplantation and autoimmune diabetes, ICOS blockade can be effective in inhibiting alloimmunity and preventing autoimmunity but is ineffective in inhibiting recurrence of autoimmunity.
