摘要
目的 :研究α 黑素细胞刺激素 (α MSH)对LPS诱导星形胶质细胞产生NO和前炎性细胞因子的影响 ,探讨α MSH的抗炎作用机制。方法 :分别用LPS或α MSH +LPS处理体外培养的大鼠脑星形胶质细胞 ,用Griess试剂测定NO ,以MTT显色法检测IL 1、IL 6和TNF α ,采用半定量RT PCR检测MIFmRNA表达。结果 :体外培养的星形胶质细胞在LPS刺激下产生NO、IL 1、IL 6、TNF α和表达MIFmRNA显著增高 ;若同时给予LPS和α MSH ,可明显降低NO、IL 1、IL 6和TNF α的产生以及MIFmRNA表达。结论 :提示α MSH抑制星形胶质细胞产生NO和前炎性细胞因子与其抑制中枢神经系统炎症反应密切相关
