Abstract:The precise steps of iNKT subset differentiation in the thymus and periphery have been controversial. We demonstrate here that the small proportion of thymic iNKT and mucosal associated invariant T cells that express CCR7 represent a multi-potent progenitor pool that gives rise to effector subsets within the thymus. Using intra-thymic labeling, we also showed that CCR7+ iNKT cells emigrate from the thymus in a Klf2 dependent manner, and undergo further maturation after reaching the periphery. Ccr7 deficiency i… "V体育官网" Show more
