Research Abstract

Regulatory T cells, lymphocytes suppressing immune reaction, highly express CTLA-4. CTLA-4 suppresses dendritic cells (DC), which maintains immune system in normal condition. It is known that FoxO3a is an essential molecule for DC suppression by CTLA-4 in a mouse model. However, Foxo3a knockdown in human DC resulted in the reduction of T cell proliferation. It is suggested that FoxO3a may augment immune reaction in human DC.
