Methods Co culture systems of RPE cells with antigen specific t lymphocyte lines and resting t lymphocytes were established in vitro.
方法建立RPE与抗原特异性T淋巴细胞系和静止淋巴细胞之间的共培养系统。
T cell can only recognize specific antigenic peptide-MHC complex on antigen-presenting cell. This is MHC restriction in antigen recognition of t cell.
细胞只能识别抗原提呈细胞表面特定的抗原肽MHC分子复合物，这就是T细胞抗原识别的MHC限制。
It has been proved that Dendritic cells (DCs) have strongly ability to present antigen. DCs can trigger t cell responses and enhance the t cell mediated anti tumor effect.
树状突细胞(DC)具有强大的抗原递呈能力，并能有效激发T细胞应答，是目前抗肿瘤免疫治疗研究的热点之一。
The first signal is the binding of antigen with TCR on T cells. The second signal is the binding of co-stimulate on the APC with their receptors presenting on T and B lymphocytes.
第一信号为抗原与T细胞受体TCR的结合，第二信号为抗原递呈细胞上的协同刺激分子与T、B淋巴细胞上的受体结合。
Objective To establish long-term cultured antigen-specific T cell line and clones and to analyze their T cell receptor usage.
目的体外建立可长期培养的抗原特异性T细胞系及克隆，并分析其T细胞受体的使用情况。
Unfortunately for the virus, t antigen also serves as a target for immune (t) cells, which can destroy infected cells and prevent the virus from spreading.
对于这种病毒来说不幸的是，T抗原同样也是免疫(t)细胞的攻击对象，也就是说，免疫细胞将摧毁受到感染的细胞来防止病毒进一步扩展。
It is assumed that the reason resulting in such change is either t cell maturation of the down regulation of t cell antigen receptors.
推测造成这种T细胞亚群变化的原因可能与T细胞的发育成熟及T细胞本身的调节有关。
Conveniently, the microRNA that targets t antigen is made late in the infectious cycle, just when t antigen is no longer essential for virus replication.
以t抗原为攻击目标的小分子rna在感染周期的最后环节才会产生，而这时t抗原已经不再是病毒繁殖的必须条件。
METHODS The T-antigen monoclonal antibody method and the galactose oxidase method were simultaneously used to detect T-antigen in large intestinal mucus of 207 cases.
方法同时采用T抗原单克隆抗体法和半乳糖氧化酶法检测207例直肠粘液中的T抗原。
Results Autologous t lymphocytes induced by DCs pulsed with myeloma lysates had stronger killing effect on myeloma cells than t lymphocytes induced by non myeloma antigen pulsed DC.
结果骨髓瘤冻融物致敏DC诱导的自身T细胞对患者骨髓瘤细胞的杀伤率远大于非致敏dc。
Results Autologous t lymphocytes induced by DCs pulsed with myeloma lysates had stronger killing effect on myeloma cells than t lymphocytes induced by non myeloma antigen pulsed DC.
结果骨髓瘤冻融物致敏DC诱导的自身T细胞对患者骨髓瘤细胞的杀伤率远大于非致敏dc。
