Producing GM-CSF: A unique T helper subset?

Abstract

GM-CSF-producing helper T cells have previously been identified to serve a nonredundant function in the initiation of autoimmune inflammation. An article by Sheng et al. recently published by Cell Research now suggests that the differentiation program of GM-CSF-producing cells from naïve CD4 T cells is distinct from that of Th1 and Th17 cells, and is regulated by the IL-7-STAT5 axis.
