Several investigators have reported that hepatocyte growth factor (HGF) may be related to the protection or reconstruction of the kidney during acute renal rejection. To address this question, we examined the relationship between HGF and acute rejection in the following two studies with rat renal transplantation models. In study 1, the relationship between serum HGF levels and acute renal rejection in iso-, allo- and allograft with cyclosporine (CsA)-treated models was examined. In study 2, the focus was whether or not the injection of recombinant HGF can prevent acute renal rejection. Our results demonstrated that HGF levels were rapidly increased during acute rejection and that recombinant HGF effectively protected the kidney from acute rejection. These results suggest that HGF may be induced as a counter-response to the renal injury and that it can be used as a reliable indicator for the diagnosis of acute rejection. We suggest that recombinant HGF suppresses the onset of the pathological changes of acute rejection.
