ABSTRACT
The effect of triptolide( TP) on VEGFA,SDF-1,CXCR4 pathway were investigated in vitro to explore the mechanism in improving platelet activation in patients with ankylosing spondylitis( AS). Peripheral blood mononuclear cells( PBMC) were used for the experiment and divided into 4 groups normal group( NC),model group( MC),triptolide group( TP),and AMD3100 group. The optimal concentration of TP was measured by the MTT method. The expressions of TNF-α,IL-1β,IL-4,IL-10,VEGFA and VEGFR were detected by ELISA. The expressions of SDF-1,CXCR4 and VEGFA were detected by real-time quantitative PCR( RT-qPCR).The expressions of SDF-1,CXCR4,VEGFA and VEGFR were detected by Western blot. The expression levels of CD62 p,CD40 L and PDGFA were detected by immunofluorescence. MTT results showed that medium-dose TP had the strongest inhibitory effect on cells at24 h. The results of ELISA and PCR showed that TP inhibited mRNA expressions of IL-1β,TNF-α,VEGFA,VEGFR and SDF-1,CXCR4 and VEGFA. The results of Western blot indicated that TP inhibited SDF-1,CXCR4 and VEGFA,VEGFR protein expressions; immunofluorescence results indicate that TP can inhibit the expressions of CD62 p,CD40 L,PDGFA. TP may regulate platelet activation by down-regulating SDF-1,CXCR4,VEGFA and VEGFR mRNA expressions,thereby down-regulating IL-1β and TNF-αexpressions,and up-regulating the expressions of IL-4 and IL-10 cytokines.
