Abstract

Abstract Forkhead box O (FoxO) is a transcription factor which is involved in cell cycle progression, cell survival and DNA-repair. Dendritic cells (DCs) are professional antigen-presenting cells which present the antigens to T lymphocytes and regulate the adaptive immunity. Previous studies indicated that FoxO1 and 3 are plays a critical role in DC maturation and DC-T cell interaction. FoxO6, a member of FoxO family, is less attended than other FoxO families, because limited expression region of FoxO6. Also, the effect of FoxO6 is still unknown. Here, we investigated the effect of FoxO6 in dendritic cells. Out data suggest that FoxO6 is expressed in murine dendritic cells. Moreover, phosphorylated FoxO6 is increased and acetylated FoxO6 is decreased during dendritic cell differentiation. We expect that FoxO6 has important role in DC differentiation and maturation, and will further investigate the functions and the mechanisms of FoxO6 on DC. And alteration of FoxO6 expression level had effect on DCs maturation.
