The natural history and pathogenesis of the pathologic lesions that define rejection of kidney transplants have not been well characterized. We studied the evolution of the pathology of rejection in mouse kidney allografts, using four strain combinat

In many circumstances kidney transplants remain viable despite extensive inflammation, permitting rejection episodes to be reversed. The mechanisms by which the kidney resists host effector mechanisms are not known. In mouse kidney transplants, resis

Class II transactivator (CIITA) induces transcription of MHC class II genes, and induces class I in some cell lines. We examined the effect of CIITA deficiency on class I and II expression in mouse kidney. In CIITA knockout (CIITAKO) mice, basal clas

The immunosuppressive drug mycophenolate mofetil (MMF) acts by releasing mycophenolic acid (MPA), which inhibits the enzyme inosine monophosphate dehydrogenase (IMPDH) and thus inhibits de novo purine synthesis. Unlike cyclosporine (CsA), MMF has no

Background Tissue injury induces MHC class II expression, which could be important in the recognition of that tissue as an allograft. The class II transcriptional activator (CIITA) is the major regulator of basal and induced MHC class II expression a

We examined the expression of MHC class I and II in the arterial endothelium of interferon-γ (IFN-γ, GKO) and IFN-γ-R (IFN-γ-R, GRKO) gene knockout mice in comparison with mice with intact IFN-γ and IFN-γ-R genes, BALB/c and 129Sv/J wild-type,

Cyclosporine (CsA) blocks T cell responses in vitro by inhibiting the phosphatase activity of calcineurin (CN) and thus preventing the activation of cytokine transcription. In the study presented here, we measured the extent of inhibition of these fu

Renal ischemic injury evokes an inflammatory response with increased cytokine and major histocompatibility complex (MHC) expression and a mild interstitial infiltrate. This "injury response" could contribute to the tendency of ischemically injured re

We studied major histocompatibility complex (MHC) and cytokine mRNA induction after renal injury in the absence of interferon-γ (IFN-γ) using IFN-γ gene knockout (GKO) mice. The left renal pedicle of normal (wild-type) and GKO BALB/c mice was clam

We noted previously that ischemic acute tubular necrosis (ATN) induces local expression of MHC products in renal epithelium. The present investigations were conducted to establish the role of IFN-gamma in the regulation of MHC antigen expression in A
