"WebT-bet serves as the master regulator of Th1 differentiation. It promotes expression of both IL-12 R beta 2 and IFN-gamma, the signature cytokine produced by Th1 cells. IL-12 R beta 2 dimerizes with IL-12 R beta 1 to form a functional IL-12 receptor complex. This renders the cells responsive to IL-12, which is critical for Th1 differentiation. " - Th1 ifn gamma
