Abstract:
AIM:To investigate LPS(lipopolysaccharide)stimulated cytokine secretion from normal rat kupffer cells in vitro. METHODS: Kupffer cells were isolated from wistar rats liver and cultured.Tumor necrosis factor -? (TNF-?) and endothelin-1(ET-1) secreted by LPS stimulated kupffer cells were detected. RESULTS: LPS had an stimulative effect on kupffer cell activity. LPS in definite concentrations promoted kupffer cell secretion.CONCLUSION: LPS promotes kupffer cell secretion, which may be associated with liver injury induced by LPS.
