Abstract:
AIM:To investigate the effect of gastrodin(GAS)on microglia-mediated inflammatory response after hypoxic-ischemic brain damage(HIBD)neonatal mice by regulating the expression of JAK1/STAT1 pathway through C-C chemokine recepeor 5(CCR5).METHODS:Forty-eight C57BL/6J mice at about 10 days after birth were randomly divided into sham group,HIBD model group and HIBD+GAS group.BV-2 microglia were divided into control(Con)group,oxygen glucose deprivation(OGD)group,oxygen glucose deprivation with gastrodin intervention(OGD+GAS)group,GAS group,Maraviroc(MVC)group,OGD+MVC group,and OGD+MVC+GAS group.The mRNA expression of CCL4 and CCR5 were detected by RT-qPCR.The protein expression of CCR5,p-JAK1,p-STAT1,tumor necrosis factor-α(TNF-α)and interleukin-1β(IL-1β)were detected by Western blot.The expression of CCR5,p-JAK1 and p-STAT1 in cells were observed by immunofluorescence staining.RESULTS:(1)Compared with sham group,the expression levels of CCL4 and CCR5 mRNA,and CCR5,p-JAK1 and p-STAT1 proteins were significantly higher in the ischemic side of the corpus callosum in HIBD group(P＜0.05).(2)Compared with Con group,the protein levels of CCR5,p-JAK1 and p-STAT1 significantly increased in BV-2 cells of OGD group(P＜0.05).The protein levels of CCR5,p-JAK1 and p-STAT1 in BV-2 cells of OGD+GAS group were significantly lower than those of OGD group(P＜0.05).(3)Maraviroc did not cause significant BV-2 cell death in the 0～80 μmol/L range.The p-JAK1 and p-STAT1 protein levels in MVC+OGD group were significantly lowered compared with OGD group(P＜0.05),but no significant difference was found between MVC+ OGD and OGD+MVC+GAS groups.CONCLUSION:Gastrodin can exert neuroprotective effects via CCR5/JAK1/STAT1 signaling pathway.
