缺乏CD4会削弱T细胞受体(TCR)信号传导对主要组织相容性复合体(MHC)II类呈递肽的响应效率。在这里,我们使用携带条件性Cd4等位基因的小鼠来研究胸腺细胞发育完成后TCR信号转导受损的后果。我们发现,CD4的损失减少了稳态的T细胞增殖监测在体内标记溴脱氧尿苷。此外,缺乏CD4的T细胞在转移到淋巴细胞减少的受体后的增殖扩增期间与表达CD4的T细胞竞争很差。这些数据表明,T细胞在稳态增殖过程中相互竞争,并表明这种竞争的基础是TCR信号传导。
Absence of CD4 impairs the efficiency of T cell receptor (TCR) signaling in response to major histocompatibility complex (MHC) class II–presented peptides. Here we use mice carrying a conditional Cd4 allele to study the consequences of impaired TCR signaling after the completion of thymocyte development. We show that loss of CD4 decreases the steady-state proliferation of T cells as monitored by in vivo labeling with bromo-deoxyuridine. Moreover, T cells lacking CD4 compete poorly with CD4-expressing T cells during proliferative expansion after transfer into lymphopenic recipients. The data suggest that T cells compete with one another during homeostatic proliferation, and indicate that the basis of this competition is TCR signaling.
