中文摘要
在本研究中,我们分析了CD 8 ^+TCRV β 14 T细胞在2,4,6-三硝基苯磺酸(TNBS)诱导的结肠炎中的功能作用如下:1. Cr<51>释放试验:CD 8 +TCR V β 14 T细胞克隆对TNBS缀合的自身脾细胞显示特异性细胞毒活性。ELISA:这些克隆在培养上清液中产生IFN-γ,但不产生IL-2和IL-4。过继转移:转移这些克隆的受体动物在暴露于低剂量TNBS时出现结肠炎。
英文摘要
In this study, We analyzed the functional role of CD8^+TCRV β 14T-cells in 2,4,6-Trinitrobenzene-sulfonic acid(TNBS) induced colitis as follows ;1. ^<51>Cr release assay : CD8^+TCR V β 14 T-cell clones showed specific cytotoxic activity against TNBS conjugated self spleen cells.2. ELISA : These clones produced IFN-γ in culture supernatant, but neither IL-2 nor IL-4.3. Adoptive transfer : Recipient animals transferred with these clones developed colitis when exposed to low doses of TNBS.
