Hemgn Protects Hematopoietic Stem and Progenitor Cells Against Transplantation Stress Through Negatively Regulating IFN‐γ Signaling (Adv. Sci. 5/2022)

Abstract

Hematopoietic Stem and Progenitor Cells In article number 2103838, Xiao-Ming Yang, Chang-Yan Li and co-workers identify a critical regulator-HEMGN, that is required for hematopoietic stem and progenitor cells (HSPCs) homing, survival, and reconstitution of blood cells during bone marrow transplantation (BMT). HEMGN acts as a protector which limits interferon-γ (IFN-γ) signaling by suppressing nuclear Stat1 tyrosine phosphorylation and assists HSPCs to combat the transplantation stress. Targeted Hemgn may be used to improve conditioning regimens and engraftment during bone marrow transplantation.
