客观的。鉴定介导类风湿性关节炎 (RA) 疾病的 T 淋巴细胞。方法。使用一组与 T 细胞受体 (TCR) Vβ 基因产物反应的单克隆抗体来分析 RA T 细胞库。结果。在研究的 5 种 TCR Vβ 基因产物中,与对照组相比,RA 患者的外周血和滑液 (SF) 中只有 Vβ17 阳性 T 细胞增加(分别为 P<0.01 和 P=0.0006)。 49 个 RA SF 样本中的 31% 和 19 个非 RA SF 样本中没有一个含有 >10% 的 Vβ17 阳性 T 细胞。激活的(Tac 阳性)T 细胞在 Vβ17 阳性滑膜 T 细胞中富集。结论。 Vβ17 阳性 T 细胞的选择性增加表明这些 T 细胞在 RA 发病机制中发挥着作用。
Objective. To identify the T lymphocytes that mediate disease in rheumatoid arthritis (RA).Methods. A panel of monoclonal antibodies reactive with T cell receptor (TCR) Vβ gene products was used to analyze the RA T cell repertoire.Results. Of 5 TCR Vβ gene products studied, only Vβ17‐positive T cells were increased in peripheral blood and synovial fluid (SF) from RA patients, compared with controls (P< 0.01 andP= 0.0006, respectively). Thirty‐one percent of the 49 RA SF samples and none of the 19 non‐RA SF samples contained >10% Vβ17‐positive T cells. Activated (Tac‐positive) T cells were enriched among Vβ17‐positive synovial T cells.Conclusion. The selective increase of Vβ17‐positive T cells suggests a role for those T cells in the pathogenesis of RA.
