CP-690550, a Janus Kinase Inhibitor, Suppresses CD4+ T-Cell–Mediated Acute Graft-Versus-Host Disease by Inhibiting the Interferon-γ Pathway

Abstract

The targeting of Janus kinase with a sensitive and specific inhibitor, CP-690550, conferred effective protection from acute GVHD induced by a semiallogeneic major histocompatibility complex class II-disparate combination. Protection from acute GVHD was largely mediated by the inhibition of IFN-γ production.
