MHC class II inhibits the generation of IL-17A+ Vγ6 γδ T cells in the thymus at perinatal stage.

ABSTRACT

Vγ6+ γδ T cells develop in the thymus at the perinatal stage and are exclusive IL-17A producers among γδ T cells. The loss of MHC class II led to the expansion of IL-17A+ Vγ6+ γδ T cells in the thymus. Thus, MHC class II in the thymus inhibits the generation of IL-17A+ Vγ6+ γδ T cells.
