AI Article Synopsis

  • Lifelong maintenance of blood cell production relies on the proper functioning of hematopoietic stem cells, which are regulated by thrombopoietin, a key cytokine.
  • Thrombopoietin not only helps maintain these stem cells but also plays a crucial role in the development of megakaryocytes, the cells responsible for producing platelets.
  • Research using thrombopoietin gene-deficient mice has revealed how thrombopoietin receptor agonists aid in sustaining stem cell populations and their differentiation, highlighting their importance in treating bone marrow failure disorders like aplastic anemia.

Article Abstract

Sustaining lifelong hematopoiesis requires maintenance, proliferation, and differentiation of hematopoietic stem cells. Thrombopoietin is a cytokine essential for regulation of hematopoietic stem cells as well as differentiation and maturation of megakaryocytes required for platelet production. Due to these properties, thrombopoietin agonists have been used to treat bone marrow failure syndromes such as aplastic anemia. Through analysis of thrombopoietin gene-deficient mice, my colleagues and I have demonstrated the mechanism of action of thrombopoietin receptor agonists in hematopoietic stem cell maintenance and differentiation. This review focuses on governance of homeostasis in the hematopoietic system by thrombopoietin signaling.

EZH2 inhibition induces pyroptosis via RHA-mediated S100A9 overexpression in myelodysplastic syndromes.

Myelodysplastic Syndromes (MDS) represent a group of heterogeneous myeloid clonal diseases derived from aberrant hematopoietic stem/progenitor cells. Enhancer of zeste homolog 2 (EZH2) is an important regulator in gene expression through methyltransferase-dependent or methyltransferase-independent mechanisms. Herein, we found EZH2 inhibition led to MDS cell pyroptosis through RNA Helicase A (RHA) down-regulation induced overexpression of S100A9, a key regulator of inflammasome activation and pyroptosis.

Somatic stem cell pools comprise diverse, highly specialized subsets whose individual contribution is critical for the overall regenerative function. In the bone marrow, myeloid-biased hematopoietic stem cells (myHSCs) are indispensable for replenishment of myeloid cells and platelets during inflammatory response but, at the same time, become irreversibly damaged during inflammation and aging. Here we identify an extrinsic factor, semaphorin 4A (Sema4A), which non-cell-autonomously confers myHSC resilience to inflammatory stress.

Transplantation-associated thrombotic microangiopathy (TMA) is a severe complication of allogeneic hematopoietic stem cell transplantation (allo-HSCT) with high mortality. As calcineurin inhibitors (CNIs) reportedly contribute to TMA via drug-induced endothelial injury, treatment of TMA often involves CNI discontinuation or dose reduction. However, renal-limited TMA, defined as biopsy-proven renal TMA without the classical triad (hemolytic anemia, thrombocytopenia, and organ damage), has rarely been reported after allo-HSCT, and its optimal management remains unknown.

Introduction: Graft-versus-host disease (GvHD) remains a major complication of allogeneic stem cell transplantation (allo-SCT), affecting 30-70% of patients (representing 800 new patients per year in the UK). The risk is higher in patients undergoing unrelated allo-SCT. About 1 in 10 patients die as a result of GvHD or through complications of its treatment.

G-CSF modulates innate and adaptive immunity via the ligand-receptor pathway of binding GCSFR in Flounder (Paralichthys olivaceus).

Electronic address:

Granulocyte colony stimulating factor (G-CSF) has been shown in mammalia to activate a series of signal transduction systems and exert various biological effects, such as controlling the differentiation, proliferation, and survival of granulocytes, promoting the movement of hematopoietic stem cells from the bone marrow to the bloodstream, and triggering the development of T cells, dendritic cells, and immune tolerance in transplants. In this study, the mRNA of flounder G-CSF (PoG-CSF) and its receptor (PoGCSFR) were detected and widely expressed in all examined tissues with the highest expression in peritoneal cells. G-CSF and GCSFR cells were observed to be abundantly distributed in the leukocytes from the peritoneal cavity, followed by head kidney.
