Thymocytes after T-lineage commitment develop in the T-cell pathway. However, in a recent study, Li et al. (2010) demonstrated that inducing to delete Bcl11b gene in these thymocytes, even in mature T cells turns these cells into natural killer (NK) cells during the culture. They called this conversion 'reprogramming', and the reprogrammed killer cells 'ITNK cells'. The ITNK cells possessed tumor-killer ability and did not indiscriminately kill normal cells. This exciting finding represents a major breakthrough towards curing cancer and identifies an important, novel transcription factor in the thymus development.
胸腺细胞在 T 细胞谱系确定后在 T 细胞途径中发育。然而,在最近的一项研究中,Li 等人(2010 年)表明,在培养过程中,即使在成熟 T 细胞中诱导删除 Bcl11b 基因,也会将这些细胞转化为自然杀伤(NK)细胞。他们将这种转化称为“重编程”,并将重编程的杀伤细胞称为“ITNK 细胞”。这些 ITNK 细胞具有肿瘤杀伤能力,不会不加区分地杀死正常细胞。这一令人兴奋的发现代表了癌症治疗的重大突破,并确定了胸腺发育中的一个重要的新型转录因子。
