Abstract

(SJL X BALB)F1 suppressed mice have, in their lymphoid tissues, a population of suppressor T cells directed specifically against a paternal gamma G2a allotype (Ig-1b). Spleen or lymph node cells from these mice were injected into syngeneic nude mice and the effect on thymus-independent synthesis of Ig-1b in the athymic recipients was determined. After the injection of suppressor cells, Ig-1b disappeared from the serum of the recipients in a time course similar to that seen in normal mice. These results indicate that suppression occurs in the absence of thymus-derived helper cells, and they suggest that Ig-1b-producing B cells are the target of allotype-suppressor cells.

摘要

(SJL×BALB)F1抑制性小鼠在其淋巴组织中有一群特异性针对父本γG2a同种异型(Ig-1b)的抑制性T细胞。将这些小鼠的脾细胞或淋巴结细胞注射到同基因裸鼠体内,并测定对无胸腺受体中不依赖胸腺的Ig-1b合成的影响。注射抑制性细胞后,Ig-1b在受体血清中消失的时间进程与正常小鼠相似。这些结果表明,在没有胸腺来源的辅助性细胞的情况下也会发生抑制作用,并且提示产生Ig-1b的B细胞是同种异型抑制性细胞的靶标。
