摘要 目的探讨相关性C型凝集素-1(Dectin-1)和白细胞介素-10(IL-10)在大鼠侵袭性肺部热处理光滑念珠菌感染的表达及意义。方法将24只大鼠随机分为两组,对照组及热处理光滑念珠菌感染组(简称感染组)。感染组建立大鼠侵袭性肺部热处理光滑念珠菌感染模型,在第3、6天观察肺组织病理形态学改变,用酶联免疫吸附测定法肺泡灌洗液中IL-10、TNF-α的表达,用蛋白免疫印迹法检测肺组织Dectin-1的表达,并与对照组(正常SD大鼠)比较。结果对照组大鼠肺组织正常。感染组肺泡结构消失,肺泡腔及间质可见大量炎性细胞浸润,与对照组相比,感染组肺组织Dectin-1及肺泡灌洗液IL-10和TNF-α的表达均呈进行性升高。结论 Dectin-1和IL-10参与了大鼠侵袭性肺部热处理光滑念珠菌感染,且IL-10在深部真菌时,起负性调节的作用。
