Abstract:Objective To observe the inhibitory effects of matrine, oxymatrine and sophordine on expression of CD91 and CD13 and secretion of TNFα in macrophage RAW264.7. Methods Macrophages were cultured in 6hole plate and coverslip was prepared. Then macropages were cultured one day with different concentrations(0,12.5,25,50,100,200 mg/L) of matrine, oxymatrine and sophordine; the expression of CD91 and CD13 by immunohistochemical dyeing was analyzed by ImagePro plus system (Media Cybemetic, Inc., 6.0 edition). Meanwhile, the levels of TNFα in the culture medium of macrophages were examined by ELISA. Results Matrine, oxymatrine and sophordine could all inhibit CD91 and CD13 expression in macrophage RAW264.7, and the inhibition varied with the concentrations of matrine, oxymatrine and sophordine; the inhibitory effect of matrine was the most prominent one. Moreover, matrine, oxymatrine and sophordine also inhibited the secretion of TNFα. Conclusion Matrine, oxymatrine and sophordine can greatly inhibit expression of CD91 and CD13 and secretion of TNFα in macrophage RAW264.7.
