Abstract

Natural killer T (NKT) cells develop from common CD4(+) CD8(+) thymocyte precursors. Transcriptional programs that regulate the development of NKT cells in the thymus development remain to be fully delineated. Here, we demonstrate a cell-intrinsic requirement for transcription factors TCF1 and LEF1 for the development of all subsets of NKT cells. Conditional deletion of TCF1 alone results in a substantial reduction in NKT cells. The remaining NKT cells are eliminated when TCF1 and LEF1 are both deleted. These data reveal an essential role for TCF1 and LEF1 in development of NKT cells.

摘要

自然杀伤T(NKT)细胞由常见的CD4(+) CD8(+)胸腺细胞前体发育而来。调节胸腺发育中NKT细胞发育的转录程序仍有待全面阐明。在此,我们证明转录因子TCF1和LEF1对所有NKT细胞亚群的发育具有细胞内在需求。单独条件性缺失TCF1会导致NKT细胞大量减少。当TCF1和LEF1都被缺失时,剩余的NKT细胞会被消除。这些数据揭示了TCF1和LEF1在NKT细胞发育中的重要作用。
