AIM: To investigate the subtype of M2 macrophages induced by Schistosoma japonicum cystatin( Sj Cystatin) and to determine the mechanism underlying these effects. METHODS: The releases of IL-10 and IL-12,and the expression of macrophage subtype markers LIGHT( M2b) and Arg-1( M2 a + M2c) were assessed by ELISA,RTq PCR and Western blot. The phosphorylation level of AKT was assessed by Western blot. RESULTS: Sj Cystatin promoted the continuous increase in IL-10 level at 6 h,12 h and 24 h,and increased the amou...
