Improvement of Sepsis by Hepatocyte Growth Factor, an Anti-Inflammatory Regulator : Emerging Insights and Therapeutic Potential

الملخص EN

Sepsis-induced multiple organ failure (MOF) is the most frequent lethal disease in intensive care units.

Thus, it is important to elucidate the self-defensive mechanisms of sepsis-induced MOF.

Hepatocyte growth factor (HGF) is now recognized as an organotrophic factor, which is essential for organogenesis during embryonic growth and regeneration in adulthood.

HGF production is enhanced in response to infectious challenges, but the increase in endogenous HGF levels is transient and insufficient, with a time lag between tissue injuries and HGF upregulation, during progression of septic MOF.

Thus, administration of active-formed HGF might be a new candidate for therapeutic development of MOF.

HGF has an ability to target endotoxin-challenged macrophages and inhibits the upregulation of inflammatory cytokines through nuclear factor-κB-inactivated mechanisms.

HGF also targets the endothelium and epithelium of various organs to suppress local inflammation, coagulation, and apoptotic death.

This paper summarizes the novel mechanisms of HGF for attenuating sepsis-related pathological conditions with a focus on sepsis-induced MOF.
