摘要:
为了检测mTOR抑制剂雷帕霉素(rapamycin)对单核细胞增生李斯特菌(Lm)在小鼠脑微血管内皮细胞内存活的影响,将不同浓度抑制剂雷帕霉素与细胞共同孵育,然后将Lm分别感染细胞,细菌菌落计数法计算胞内细菌数量,MTT法检测抑制剂雷帕霉素对细胞活性的影响,酶联免疫吸附试验(ELISA)检测抑制剂雷帕霉素对Lm介导的IFN-γ和IL-6分泌的影响,利用试剂盒检测caspase-1活性。结果表明:抑制剂雷帕霉素在5、10、25 nmol/L浓度时不影响细胞活性,雷帕霉素显著抑制了Lm在细胞,且与雷帕霉素浓度和感染时间相关,雷帕霉素显著提高了Lm介导的IFN-γ、IL-6、caspase-1、IL-1β和NLRP3的mRNA水平。结论:本研究表明,mTOR抑制剂雷帕霉素可调控细胞内Lm的存活,雷帕霉素可增强Lm介导的细胞炎性体水平,为Lm引起脑膜炎的致病机制提供科学依据。
