We investigated whether atorvastatin (AT) was capable of protecting animals from acute graft-versus-host disease (aGvHD) across major-MHC mismatch barriers. AT treatment of the donor induced a Th-2 cytokine profile in the adoptively transferred T cells and reduced their in vivo expansion, which translated into significantly reduced aGvHD lethality. Host treatment down-regulated costimulatory molecules and MHC class II expression on recipient APCs and enhanced the protective statin effect, without impacting Graft-versus-leukemia (GvL) activity. The AT effect was partially reversed in STAT6-/- donors and abrogated by L-mevalonate, indicating the relevance of STAT6 signaling and the L-mevalonate pathway for AT mediated aGvHD protection. AT reduced prenylation levels of GTPases, abolished T-bet expression and increased c-MAF and GATA-3 protein in vivo. Thus, AT has significant protective impact on aGvHD lethality by Th-2 polarization and inhibition of an uncontrolled Th-1 response while maintaining GvL activity, which is of great clinical relevance given the modest toxicity profile of AT.
