| Abstract: | AIM: To investigate the effect of recombinant human interleukin-10 (rhIL-10) on IL-6 and TNF-α levels in serum and liver of mice exposed to lipopolysaccharide (LPS). METHODS: rhIL-10 was prepared by using genetic engineering technology. Mice were intraperitoneally with 500 μg of LPS, and then were treated intravenously with various dosages of rhIL-10. The levels of IL-6 and TNF-α in hepatic tissue and serum were determined by ELISA at 12 h, 24 h, 48 h and 72 h post rhIL-10 treatment. RESULTS: rhIL-10 markedly inhibited the increase in IL-6 and TNF-α levels in hepatic tissue and serum at 12 h after rhIL-10 treatment in LPS-challenged mice, and the inhibition effect was significant at 24-48 h after rhIL-10 treatment （P＜0.05）. CONCLUSION: rhIL-10 can inhibit the increase in IL-6 and TNF-α levels induced by LPS in mice. |
