T细胞前体在进入胸腺后的多代细胞中保持发育可塑性,保留了巨噬细胞,树突细胞甚至肥大细胞命运的发育替代品。这种可塑性的潜在调控基础是早期T细胞分化依赖于转录因子,这些转录因子也可以促进替代性发育程序。因素间的竞争,加上环境信号,使这些转移受到控制。在这里的途径导致几个谱系的替代早期pro-T细胞进行审查,密切关注的三个重要因素,加塔-3,PU.1和Notch-Delta信号的作用机制,其平衡似乎是必不可少的T细胞的规范。
T-cell precursors remain developmentally plastic for multiple cell generations after entering the thymus, preserving access to developmental alternatives of macrophage, dendritic cell, and even mast-cell fates. The underlying regulatory basis of this plasticity is that early T-cell differentiation depends on transcription factors which can also promote alternative developmental programs. Interfactor competition, together with environmental signals, keep these diversions under control. Here the pathways leading to several lineage alternatives for early pro-T cells are reviewed, with close focus on the mechanisms of action of three vital factors, GATA-3, PU.1, and Notch-Delta signals, whose counterbalance appears to be essential for T-cell specification.
