| Research Abstract |
We demonstrated that direct effects of HGF on macrophages during leads to inhibition of the NF-?b activation and subsequent transcription of pro-inflammatory cytokines. Furthermore, we found, using a mouse model of sepsis, that HGF-mediated up-regulation of hemeoxygenese-1 is required for HGF to inhibit the onset of septic acute renal failure, lung injury and hepatitis. Based on the present data, we conclude that enhancement of the HGF-hemeoxygenase-1 pathway in macrophages can be a reasonable strategy to improve the sepsis-related pathological conditions.
