TCF-1和LEF-1对早期T细胞发育至关重要,但它们在CD4+CD8+双阳性(DP)阶段之后的作用尚不清楚。通过特异性消融DP胸腺细胞,我们证明TCF-1和LEF-1的缺乏减少了CD4+ T细胞的输出,并将CD4+ T细胞重定向到CD8+ T细胞的命运。TCF-1和lev -1在CD4-CD8谱系选择中的作用部分是由Th-POK的直接正调控介导的。此外,TCF-1和LEF-1的缺失意外地导致CD8+谱系性T细胞中CD4降低,而不影响Runx因子的表达。相反,TCF-1物理上与Runx3相互作用,共同沉默Cd4基因。因此,TCF-1和LEF-1通过不同的遗传线路来编程CD4+命运决定,并建立CD8+ T细胞身份。
TCF-1 and LEF-1 are essential for early T cell development, but their roles beyond the CD4+CD8+ double positive (DP) stage are unknown. By specific ablation in DP thymocytes, we demonstrated that deficiency in TCF-1 and LEF-1 diminished CD4+ T cell output and redirected CD4+ T cells to a CD8+ T cell fate. The role of TCF-1 and LEF-1 in CD4-CD8 lineage choice was partly mediated by direct positive regulation of Th-POK. Furthermore, loss of TCF-1 and LEF-1 unexpectedly caused CD4 derepression in CD8+ lineage-committed T cells without affecting the expression of Runx factors. Instead, TCF-1 physically interacted with Runx3 to cooperatively silence the Cd4 gene. Thus, TCF-1 and LEF-1 adopt distinct genetic wiring to program CD4+ fate decision and establish CD8+ T cell identity.
