Immune memory was thought to be unique to cells of the adaptive immune system. In this issue of Cell Stem Cell, de Laval et al. (2020) describe persistent epigenetic modifications in hematopoietic stem cells following an inflammatory insult with LPS as a mechanism by which immune memory may be established.

造血干细胞中炎症的表观遗传足迹。

免疫记忆被认为是适应性免疫系统细胞所特有的。在本期《细胞干细胞》中，de Laval等人。（2020）描述了在用LPS作为建立免疫记忆的机制的炎性损伤之后，造血干细胞中持续的表观遗传学修饰。
