Committing to a differentiation pathway means leaving alternative pathways behind. Adoue et al. (2019) report that the H3K9-methyltrasferase Setdb1 plays a role in inhibiting the Th1 program in committed Th2 cells, and mechanistically, its role might relate to the selective targeting of endogenous retroviruses adjacent to Th1 enhancers.
承诺走一条分化途径意味着要放弃其他途径。Adoue 等人(2019 年)报告称,H3K9-甲基转移酶 Setdb1 在抑制已分化的 Th2 细胞中的 Th1 程序中发挥作用,从机制上讲,其作用可能与选择性靶向 Th1 增强子附近的内源性逆转录病毒有关。
