+ lymphocytes express functionally heterogeneous profiles of cytokine production. CD26 is an integral membrane glycoprotein, that is, a marker of Th1-like cytokine development. The purpose of the present study was to compare the immuno-expression of CD26 receptor in periodontal sites with and without clinical attachment loss (CAL). Five patients with rapidly progressing periodontitis and one with juvenile periodontitis were investigated. Each patient presented at least one site with and without CAL. Ten sites with CAL and nine without any CAL were biopsied, followed by the immunohistochemical identification of the CD26 receptor using the MIB-DS2/7 antibody. The results demonstrated that the percentage of positive cells for this antigen in the periodontal sites with CAL was not significantly different from those without attachment loss. Therefore, Th1 cell impairment may not be directly involved with periodontal attachment loss."> CD26免疫表达和牙周病进展 - raybet雷竞app,雷竞技官网下载,雷电竞下载苹果

CD26免疫表达和牙周病进展

抽象的

免疫机制参与人慢性炎症牙周病(CIPD)的发病机制。人类CD4 + 淋巴细胞表达了细胞因子产生的功能性异质谱。CD26是一种整体膜糖蛋白,即Th1样细胞因子发育的标志物。本研究的目的是将CD26受体的免疫表达与临床附着损失(CAL)的牙周位点进行比较。调查了五名迅速进展的牙周炎和具有少年牙周炎的患者。每位患者呈现至少一个有和没有CAL的网站。具有CAL和九个没有任何CAL的十个位点是活检的,然后使用MIB-DS2 / 7抗体的CD26受体的免疫组化鉴定。结果表明,在没有附着损失的情况下,牙周部位在牙周部位中该抗原的阳性细胞的百分比没有显着差异。因此,Th1细胞损伤可能不会直接参与牙周附着损失。
