Intrinsic STAT4 Expression Controls Effector CD4 T Cell Migration and Th17 Pathogenicity.

ABSTRACT: Effector CD4 T cells are central to the development of autoimmune chronic inflammatory diseases, yet factors that mediate pathogenicity remain ill-defined. Single-nucleotide polymorphisms in the human STAT4 locus are associated with susceptibility to multiple autoimmune disorders, and Stat4 is linked to the pathogenic Th17 gene signature; however, Th17 cells differentiate independently of STAT4. Hence the interplay between STAT4 and CD4 T cell function, especially Th17 cells, during autoimmune disease is unclear. In this article, we demonstrate that CD4 T cell-intrinsic STAT4 expression is essential for the induction of autoimmune CNS inflammation in mice, in part by regulating the migration of CD4 T cells to the inflamed CNS. Moreover, unbiased transcriptional profiling revealed that STAT
