Expression of Th1/Th2 chemokines and their receptors in the lesions of bullous pemphigoid / 中国免疫学杂志

ABSTRACT

Objective:To investigate the expression of Th1 chemokine CXCL9,CXCL10,CXCL11,Th2 chemokine CCL22 and their receptors in the lesions of bullous pemphigoid (BP).Methods:Immunohistochemical assay was performed to detect the expression of CXCL9,CXCL10,CXCL11,CCL22 and their receptors CXCR3 and CCR4 in BP lesions and normal control skin.Results:CXCL9,CXCL10,CXCL11,CCL22,CXCR3 and CCR4 were overexpressed in BP lesions than those in normal control skin (P＜0.01).The positive rates of CXCL9,CXCL10,CXCL11 and CXCR3 in BP lesions were 50%(15/30),46.7%(14/30),46.7%(14/30) and 53.3%(16/30),respectively.The positive rates of CCL22 and CCR4 were 66.7% (20/30) and 56.7% (17/30).Conclusion:The overexpression of Th1 chemokine CXCL9,CXCL10,CXCL11,Th2 chemokine CCL22 and their receptors may play important roles in the pathogenesis of BP.
