摘　　要：目的检测滤泡辅助性T细胞（Tth）趋化因子受体5（CXCR5）在大疱性类天疱疮患者皮损中的表达，分析和探讨CXCR5在大疱性类天疱疮发病机制中的作用。方法应用免疫组化法检测16例大疱性类天疱疮患者皮损及10例健康人皮肤中CXCR5的表达。结果CXCR5在健康人皮肤表达于基底细胞层，主要表达于细胞质、细胞膜处；在大疱性类天疱疮皮损中表达于基底细胞层与棘细胞层。CXCR5在健康人皮肤中阳性细胞表达均数为11．16±4．47，在大疱性类天疱疮患者皮损中为35．70±12．20，两组差异有统计学意义（t=6．07，P〈0．01）。结论CXCR5可能参与大疱性类天疱疮的发病。Objective To study the role of CXC chemokine receptor 5 （CXCR5） in the pathogenesis of bullous pemphigoid （BP） by detecting the expression of CXCR5 on follicular helper T （Tfh） ceils in skin lesions of BP. Methods An immunohistochemical procedure was used to detect CXCR5 expression in biopsy specimens from skin lesions of 16 patients with BP and normal skin of 10 healthy individuals. Results CXCR5 was mainly expressed in the cytoplasm and membrane of Tfh cells in the basal cell layer of normal skin as well as in both basal cell layer and prickle cell layer of BP lesions. The number of CXCR5-positive cells per high power field （× 400） was 11.16 ± 4.47 in normal skin specimens, significantly lower than that in lesional skin specimens （35.70 ± 12.20, t = 6.07, P 〈 0.01 ）. Conclusion CXCR5 may be involved in the pathogenesis of BP.
