摘要 目的:探讨Toll样受体4(TLR4)在隐球菌性脑膜炎患者外周血中蛋白的表达。方法:收集30例隐脑患者和30例健康体检者全血,采用流式细胞术检测TLR4的蛋白表达,ELISA法检测血清中IL-12、IL-4的表达,并用免疫散射法检测血清IgG、IgA、IgM的含量,并分析TLR4与它们的相关性。结果:隐球菌性脑膜炎患者TLR4蛋白表达显著低于对照组(P<0.05),且TLR4蛋白表达水平与IgG、IL-12显著相关(分别为r=0.4369、P<0.001,r=0.5344、P<0.001),与IL-4(r=0.0111,P=0.6168)不相关。结论:隐脑患者TLR4蛋白表达显著下降,IgG、IL-12与TLR4蛋白的变化具有一定的相关性,为我们进一步研究隐脑的致病机制打下基础。
