Abstract:
:We studied major histocompatibility complex (MHC) and cytokine mRNA induction after renal injury in the absence of interferon-gamma (IFN-gamma) using IFN-gamma gene knockout (GKO) mice. The left renal pedicle of normal (wild-type) and GKO BALB/c mice was clamped for 60 minutes; cytokine and MHC mRNA expression were monitored in the injured kidney and compared to the contralateral control kidney. After a single episode of ischemic injury, the expression of mRNA for MHC class I and II, interleukin-2, interleukin-10, granulocyte-macrophage colony-stimulating factor, tumor necrosis factor-alpha, and transforming growth factor-beta 1 was increased in wild-type and GKO mice, whereas preproepidermal growth factor (ppEGF) was reduced. IFN-gamma expression was induced in wild-type mice but absent in the GKO mice. Therefore, local injury was equally effective in both wild-type and GKO mice with equivalent cytokine and MHC mRNA induction, proving that local tissue injury can induce MHC expression by non-IFN-gamma factors.
