【摘要】:目的分析组蛋白去乙酰化酶(HDAC)抑制剂丙戊酸(VPA)对百草枯(PQ)和脂多糖(LPS)诱导的巨噬细胞炎性极化的作用。方法小鼠巨噬细胞RAW264.7 37℃、5%CO2条件下培养,稳定传代后分组,分别给予以下处理:(1)PQ;(2)PQ+VPA(HDACⅠ和Ⅱa类抑制剂);(3)PQ+Apicidin(HDACⅠ类抑制剂);(4)PQ+MC1568(HDACⅡa类抑制剂);(5)LPS;(6)LPS+VPA;(7)LPS+Apicidin;(8)LPS+MC1568。8 h后收集各组细胞上清及细胞团,RT-PCR、ELISA及流式细胞检测巨噬细胞表型标志物的表达。结果 PQ与LPS均促进巨噬细胞向促炎表型极化;VPA、Apicidin和MC1568均抑制PQ、LPS诱导巨噬细胞表型极化作用,但抑制作用不完全相同。结论 VPA抑制PQ和LPS诱导的巨噬细胞促炎活性,但对PQ和LPS的作用方式各有特点。
