摘要
目的:观察梅毒患者外周血单核细胞(PBMC)表面Toll样受体2、6(TLR2,TLR6)的表达变化及其意义。方法:选取显性梅毒患者87例,采用流式细胞仪检测外周血单核细胞表面TLR2、TLR6蛋白表达水平(荧光强度)以及TLR2阳性细胞率,并与50例健康者作为对照组进行比较。结果:显性梅毒患者组与对照组比较:患者外周血单核细胞TLR2、TLR6的表达水平均明显升高,TLR2高于TLR6,且一期梅毒患者低于二期梅毒患者,差异均有统计学意义(P<0.05);TLR2+CD14+、TLR6+CD14+细胞的阳性率低于对照组,且一期梅毒患者低于二期梅毒患者,差异均有统计学意义(P<0.05);MFI(TLR2)与TLR2+CD14+阳性率、MFI(TLR6)与TLR6+CD14+阳性率,在整个研究对象群体中无明显相关性(r=0.096、r=0.089,P>0.05),但在显性梅毒患者中呈正相关(r=0.813、r=0.752,P<0.05);所有的差异与性别无关,但与年龄有关。结论:梅毒患者TLR2与TLR6的表达显著上调,与病程和免疫状态有关,与性别无关。
Objective: To explore the correlation of toll-like receptor 2 and toll-like receptor 6 expression on the surface of the peripheral blood mononuclear cells of symptomatic syphilitic patients.Methods:The protein expression of TLR2 and TLR6(mean fluorescence intensity,MFI) and the precentage of TLR2^+CD14^+ and TLR6^+CD14^+ positive cells were evaluated through flow cytometric analysis with peripheral blood monocytes in 87 symptomatic syphilitics and 50 healthy controls.Results:The syphilis dominant group compared with the control group: patients with peripheral blood mononuclear cells TLR2 and TLR6 expression level was significantly increased,and a lower than syphilis patients with secondary syphilis,the differences were statistically significant(P〈0.05);TLR2^+CD14^+ and TLR6^+CD14^+ cells in the positive rate is lower than the control group,and a lower than syphilis patients with secondary syphilis,the differences were statistically significant(P〈0.05).In the entire study,MFI(TLR2) and TLR2^+CD14^+ rate、MFI(TLR6) and TLR6^+CD14^+ all have no significant correlation(r=0.096、r=0.089,P〉0.05),but in symptomatic syphilitics group has significant correlation(r=0.813、r=0.752,P〈0.05).All were unrelated to sex differences,but in the age-related.Conclusion:Syphilis in patients with TLR2 and TLR6 expression increases significantly with the course of disease and immune status,but gender has nothing to do with it.
