Research Abstract |
Sox4 is a transcription factor that regulates various developmental processes. We found that Sox4 was induced by TGFbeta and negatively regulated the transcription factor Gata3, the master regulator of Th2 cell development and allergic inflammation, by two distinct mechanisms. First, Sox4 bound to GATA3, preventing its binding to GATA3 consensus DNA sequences. Second, Sox4 bound to the promoter region of the gene encoding IL-5, a Th2 cytokine, and preventing binding of GATA3 to this promoter. Th2 driven airway inflammation was modulated by alterations in Sox4 expression. Thus, Sox4 acts as a downstream target of TGFbeta to inhibit GATA3 function and Th2-dependent allergic inflammation.
