目的 探讨强直性脊柱炎(AS)患者外周血T细胞受体β链可变区互补决定区3(TCRBV CDR3)谱系多态性,为AS免疫发病机制研究提供实验依据.方法 采用反转录-聚合酶链反应(RT-PCR)扩增AS患者外周血单个核细胞(PBMC)中T细胞TCR BV的26个亚家族CDR3,经免疫扫描谱型技术分析TCR BV CDR,3的谱系多态性情况.结果 20例活动期AS患者TCR BV CDR3扫描谱型均出现非正态的异常峰型,包括单峰、寡峰/寡峰趋势、偏峰和不规则异常峰型.其中有18例患者部分亚家族出现寡克隆/寡克隆趋势增生,有1例患者BV16和BV18的2个亚家族出现单克隆增生.5名健康对照PBMC TCR BV CDR3谱型绝大多数呈高斯分布.结论 AS患者外周血TCR BV CDR3谱系具有显著多态性和谱系漂移特点,进一步表明T细胞在AS免疫发病机制中扮演重要角色.单/寡克隆增生的T细胞有可能是AS发病中的自身反应性T细胞.
