The development of T cells in the thymus involves several differentiation and proliferation events, during which hematopoietic precursors give rise to T cells ready to respond to antigen stimulation and undergo effector differentiation. This review addresses signaling and transcriptional checkpoints that control the intrathymic journey of T cell precursors. We focus on the divergence of alphabeta and gammadelta lineage cells and the elaboration of the alphabeta T cell repertoire, with special emphasis on the emergence of transcriptional programs that direct lineage decisions.
胸腺中 T 细胞的发育涉及几个分化和增殖事件,在此期间,造血前体产生准备对抗原刺激做出反应并进行效应分化的 T 细胞。本综述讨论了控制 T 细胞前体胸腺内途径的信号转导和转录检查点。我们专注于 alphabeta 和 gammadelta 谱系细胞的分歧以及 alphabeta T 细胞库的阐述,特别强调指导谱系决定的转录程序的出现。
