rc.~一群卡恩在西班牙塞戈维亚的一个鼓舞人心的地方聚集在一起,交流关于T细胞的信息和意见。在这份报告中,提出的新的、未发表的发现,以及在会议期间产生的想法,在最近的一系列讨论中进行了讨论。T细胞的个体发育和亚群通过对不同类型T细胞的分析,揭示了,~ 13和~ 14 T细胞之间的谱系关系。转基因小鼠如果TCR转基因小鼠中含有沉默子,则T细胞在TCR转基因小鼠中正常发育。2.因此,向伊拉细胞谱系的定型似乎不是由生产性α和β基因重排决定的,而是由可能与B链表达有关的核蛋白决定的。在小鼠中,在个体发育的不同时间,在胸腺内和外周产生不同的~/6 T细胞亚群(表1)。在胎儿胸腺tvvo同质亚群?在连续的重叠波中发生。由这些子集表达的TCR的可变结构域由Va 1和几个V中的一个(分别为V~ 5和V~ 6)编码。基因.这些基因在妊娠第13天表达(A. Hayday,Yale).在生产性重排的瓦尔,V.~ 5、V 6个基因中最引人注目的是3.4个。O.以来

The variable domains of the TCR that are expressed by these subsets are encoded by Va 1 and one (V~ 5 and V~ 6 respectively) of several V.~ genes. These genes are expressed by day 13 of gestation (A.
