尽管B细胞激活和随后的免疫球蛋白产生是慢性炎症性牙周病的免疫病理学特征,但共刺激分子在体液免疫中的原位表达尚未得到研究。在本研究中,我们通过免疫组织化学方法检测了淋巴细胞上 CD40、CD40 配体 (CD40L)、CD80、CD86、CD28 和溶细胞性 T 淋巴细胞相关抗原 4 (CTLA-4) 的表达。从 14 名患有中度至晚期成人牙周炎的患者的牙龈组织样本中制备低温切片。还通过流式细胞术研究了外周血 T 细胞表达 CD40L 和 CTLA-4 以及外周血 B 细胞表达 CD80 和 CD86 的体外动力学。分别计算 CD3+ 和 CD19+ 细胞数的 CD40L、CD28 和 CTLA-4 以及 CD40、CD80 和 CD86 的阳性表达百分比。流式细胞术分析表明,激活后外周血T细胞上CD40L和CTLA-4以及B细胞上CD80和CD86的表达上调。虽然牙龈组织中大多数 T 细胞和 B 细胞分别表达 CD28、CD80 和 CD86,但 CD40L 和 CTLA-4 的表达较低,但样本之间差异很大。此外,这两种分子似乎在病变中相互表达。由于 CD40L 和 CTLA-4 表达都是通过刺激短暂诱导的,因此分子表达的变异性可能反映了免疫活性和参与病变 B 细胞激活的调节。
Although B cell activation and subsequent immunoglobulin production are the immunopathological features of chronic inflammatory periodontal disease, in situ expression of costimulatory molecules in humoral immunity has not been investigated. In the present study we examined the expression of CD40, CD40 ligand (CD40L), CD80, CD86, CD28 and cytolytic T lymphocyte‐associated antigen‐4 (CTLA‐4) on lymphocytes immunohistochemically. Cryostat sections were prepared from the gingival tissue samples of 14 patients with moderate to advanced adult periodontitis. In vitro kinetics of the expression of CD40L and CTLA‐4 by peripheral blood T cells and that of CD80 and CD86 by peripheral blood B cells were also investigated by flow cytometry. Positive percentage expression of CD40L, CD28 and CTLA‐4, and CD40, CD80 and CD86 was calculated for the number of CD3+ and CD19+ cells, respectively. Flow cytometric analysis demonstrated that the expression of CD40L and CTLA‐4 on T cells, and CD80 and CD86 on B cells of peripheral blood was up‐regulated upon activation. While most T cells and B cells expressed CD28, and CD80 and CD86, respectively, in gingival tissues, the expression of CD40L and CTLA‐4 was lower but highly variable between specimens. Furthermore, these two molecules seemed to be expressed reciprocally in the lesion. As both CD40L and CTLA‐4 expression are induced transiently by stimulation, variability in the expression of the molecules may reflect immunological activities and participation in the regulation of B cell activation of the lesion.
