Cutting edge: an alternative pathway of CD4+ T cell differentiation is induced following activation in the absence of gamma-chain-dependent cytokine signals.

Abstract excerpt

This report addresses the role of gamma-chain cytokine signals in regulating CD4(+) T cell differentiation following activation. Using murine CD4(+) T cells lacking the Jak3 tyrosine kinase, we show that activation of these cells in the absence of gamma-chain-dependent cytokine signals induces an alternative pathway of T cell differentiation. Specifically, activated Jak3(-/-) CD4(+) T cells produce IL-10,...
