Abstract

Purified Ly1 cells induce other T-cell sets to exert potent feedback inhibitory activity and this T-T interaction has been shown to play an important role in regulating in vivo immune responses. Approximately 2/3 of Ly1 cells also express the Qa1 surface phenotype (Ly1:Qa1+ cells). The experiments reported here indicate that Ly1:Qal+ cells are responsible for induction of feedback inhibition and that signals from both Ly1:Qal+ cells and Ly1:Qal- cells are required for optimal formation of antibody by B cells.

摘要

纯化的Ly1细胞可诱导其他T细胞亚群发挥强大的反馈抑制活性,并且这种T细胞与T细胞间的相互作用已被证明在调节体内免疫反应中发挥重要作用。大约2/3的Ly1细胞也表达Qa1表面表型(Ly1:Qa1+细胞)。本文报道的实验表明,Ly1:Qa1+细胞负责诱导反馈抑制,并且来自Ly1:Qa1+细胞和Ly1:Qa1-细胞的信号都是B细胞最佳抗体形成所必需的。
