Dysregulated T helper cell differentiation in the absence of interferon regulatory factor 4

Abstract excerpt

Certain IFN regulatory factor (IRF) transcription factors indirectly influence T helper (Th) cell differentiation by regulating the production of IL-12. Here, we show that IRF4 directly regulates Th cell differentiation in vitro and in vivo during murine leishmaniasis. In the absence of IRF4, IL-12-induced Th1 cell differentiation was compromised, while IL-4 failed to induce Th2 cell differentiation. Instead,...
