热休克蛋白 Heat Shock Proteins (HSPs)是在从细菌到哺乳动物中广泛存在一类热应激蛋白质。当有机体暴露于高温的时候,就会由热激发合成此种蛋白。

背景及目的:

热休克蛋白 Heat Shock Proteins (HSPs)是在从细菌到哺乳动物中广泛存在一类热应激蛋白质。当有机体暴露于高温的时候,就会由热激发合成此种蛋白,来保护有机体自身。腹泻型肠易激综合征的具体和准确的发病机制仍不清楚。本项研究旨在探索腹泻型肠易激综合征中热休克蛋白27(HSP27)的在调节肠道上皮细胞的炎症反应中的作用。

 

 

方法:

用KRIBB3(HSP27的磷酸化抑制剂)预处理人结肠上皮细胞系Caco-2和NCM460,然后用脂多糖刺激不同的时间。用膜联蛋白V / PI测定法检查了Caco-2和NCM460细胞的凋亡率。使用细胞计数试剂盒测定法测定细胞生长,并通过ELISA分析细胞上清液中IL-1β和IL-6的表达水平。此外,通过蛋白质印迹法检测HSP27的表达水平和核因子-κB(NF-κB)信号通路。

 

 

结果:

脂多糖刺激可促进结肠上皮细胞中HSP27的表达。暴露于LPS后,HSP27在丝氨酸中被磷酸化。KRIBB3处理可大大加剧脂多糖诱导的结肠上皮细胞的凋亡,生长抑制和炎性因子表达。此外,KRIBB3抑制了NF-κB-α的磷酸化和NF-κB的激活。小干扰RNA使基因沉默,表明HSP27的磷酸化可能调节NF-κB途径。

 

 

结论:

HSP27在肠道人类结肠上皮细胞的炎症反应中起重要作用。HSP27可能通过调节NF-κB通路来保护肠上皮细胞免受损害。
