| 摘 要： | 目的:探讨CXCR7在牙周炎中的表达、分布及SDF-1/CXCR7生物学轴在牙周炎中的作用。方法:运用免疫组化的方法检测SDF-1、CXCR4、CXCR7在15例正常的牙龈组织和15例牙周炎组织中的表达,同时运用PCR方法检测15例正常的牙龈组织和15例牙周炎组织中的表达情况。结果:免疫组化和PCR的结果均显示SDF-1、CXCR4、CXCR7在牙周炎组织中表达增高,高于正常牙龈组织(P<0.05)。SDF-1与CXCR7呈正相关关系(γ=0.533,P=0.041)。CXCR4和CXCR7的表达呈正相关关系(γ=0.533,P=0.041)。结论:CXCR7在牙周炎微环境中的不同细胞群过表达,在牙周炎的病理过程中发挥作用,可能是治疗牙周炎的一个新的作用靶点。

| Abstract: | Objective:To investigate the expression and distribution of CXCR7 in periodontitis and the role of SDF-1/CXCR7 biological axis in periodontitis.Methods:Immunohistochemical method and PCR were used to detect the expression of SDF-1,CXCR4,and CXCR7 in 15 normal gingival tissues and 15 periodontitis tissues.Results:The expressions of SDF-1,CXCR4,and CXCR7 in periodontitis tissues were higher than those in normal gingival tissues(P<0.05).There was a positive correlation between SDF-1 and CXCR7(γ=0.533,P=0.041),and between CXCR4 and CXCR7(γ=0.533,P=0.033,P<0.01).CXCR7 was expressed in inflammatory cells of periodontitis and vascular endothelial cells associated with inflammation.Conclusion:The overexpression of CXCR7 in the microenvironment of periodontitis may play a role in the pathological process of periodontitis,which may be a new target for the treatment of periodontitis. |
