Abstract

We have used PCR to study the expression of T-cell antigen receptor beta RNA containing particular variable region (V) elements from transcripts directly in the cells isolated from joints and lymph nodes of B10.Q mice (H-2q) immunized with chicken type II collagen. Our data show that the T cells present in arthritic joints expressed only a few V beta transcripts--V beta 2, -6, -7, -8.2, -9, -10, and -15. V beta 6 and -8.2 were expressed predominantly (six out of seven animals) while others were expressed at a relatively low level in different animals. In lymph node cells, transcripts for V beta 6, -8.2, and -9 were detected in four out of seven animals. The data indicate that in collagen-induced arthritis there is a restrictive usage of TCR V beta elements and that V beta 6 and -8.2 are probably used preferentially.

摘要

我们运用聚合酶链反应(PCR)技术,直接在从用鸡II型胶原免疫的B10.Q小鼠(H-2q)的关节和淋巴结分离出的细胞转录本中,研究含有特定可变区(V)元件的T细胞抗原受体βRNA的表达情况。我们的数据显示,存在于关节炎关节中的T细胞仅表达少数几种Vβ转录本——Vβ2、-6、-7、-8.2、-9、-10和-15。Vβ6和-8.2表达最为显著(7只动物中有6只),而其他转录本在不同动物中表达水平相对较低。在淋巴结细胞中,7只动物中有四只检测到Vβ6、-8.2和-9的转录本。这些数据表明,在胶原诱导的关节炎中,TCR Vβ元件的使用具有限制性,并且Vβ6和-8.2可能被优先使用。
