从研究TCV在防治自身免疫性疾病中的作用机制表明，人为的TCV免疫，建立了拮抗T细胞的免疫应答，使免疫网络产生上调作用，抑制了原有的或即将出现的相关T细胞的功能，由此推测，是否能够把同种反应性T细胞作为TCV，来建立抗同种免疫反应的内环境，诱导抗原特异性的同种免疫耐受或免疫低反应性。

Objective: The first aim of this study was to investigate bcr-abl associated T cell receptorVαand Vβgene repertoire by analyzing the restricted usage and clonal expansion of TCRVαand Vβsubfamily T cells from the normal individual peripheral blood induced bybcr-abl peptideso The second aim was to construct the idiotype TCR Vα-PIRES-TCR Vβeukaryotic vector and investigate its expression in vitro.
