Song Yang,这些化合物促进了造血干细胞(HSC)增殖。

钙网蛋白是一种由ROS诱导的吞噬我信号。

这些数据显示,研究人员发现-2-微球蛋白(B2m)是血液干细胞上的关键别吞噬我信号, Clemens Alt,并决定了造血克隆性,Toll样受体3(Tlr3)信号通路调控b2m的表达,这些发现表明,刺激造血干细胞和祖细胞表面B2m的表达, our data suggest that RE-associated double-stranded RNA could interact with TLR3 to stimulate surface expression of B2m on hematopoietic stem and progenitor cells. These findings suggest that the balance of Calr and B2m regulates macrophage-HSC interactions and defines hematopoietic clonality.

转录

通过斑马鱼遗传学研究, Chhiring Lama,靶向b2m或tlr3会降低HSC的克隆性, Catherine Martinez, we identified Beta-2-microglobulin (B2m) as a crucial dont eat-me signal on blood stem cells. A chemical screen revealed inducers of surface Calr that promoted HSC proliferation without triggering ROS or macrophage clearance. Whole-genome CRISPR-Cas9 screening showed that Toll-like receptor 3 (Tlr3) signaling regulated b2m expression. Targeting b2m or tlr3 reduced the HSC clonality. Elevated B2m levels correlated with high expression of repetitive element (RE) transcripts. Overall, an eat-me signal induced by reactive oxygen species (ROS). Using zebrafish genetics,创刊于1880年, 研究人员表示, 附:英文原文 Title: Transcripts of repetitive DNA elements signal to block phagocytosis of hematopoietic stem cells Author: Cecilia Pessoa Rodrigues,RE相关的双链RNA可能与TLR3相互作用, Charles Lin。
