We have determined the life span of naive CD4-8+ T cells in T cell receptor transgenic mice. We find that such cells do not divide in secondary lymphoid organs in both normal euthymic mice and T cell-deficient mice. By both continuous labeling and by chasing pulse-labeled cells, we find that the minimum life span of the naive T cells is in the order of 8 wk.
我们已经确定了T细胞受体转基因小鼠中初始CD4-8+T细胞的寿命。我们发现,在正常胸腺正常的小鼠和T细胞缺陷小鼠的次级淋巴器官中,此类细胞均不分裂。通过连续标记和追踪脉冲标记的细胞,我们发现初始T细胞的最短寿命约为8周。
