Human Erythroid Progenitors Are Directly Infected by SARS-CoV-2: Implications for Emerging Erythropoiesis in Severe COVID-19 Patients

open access: yesStem Cell Reports, 2021
Summary We document here that intensive care COVID-19 patients suffer a profound decline in hemoglobin levels but show an increase of circulating nucleated red cells, suggesting that SARS-CoV-2 infection either directly or indirectly induces stress ...

Dapagliflozin Suppresses Hepcidin And Increases Erythropoiesis.

open access: yesJournal of Clinical Endocrinology and Metabolism, 2020
CONTEXT Dapagliflozin and other SGLT2 inhibitors are known to increase hematocrit possibly due to it diuretic effects and hemoconcentration. OBJECTIVE Since type 2 diabetes is a pro-inflammatory state and since hepcidin, a known suppressor of ...

Development of luspatercept to treat ineffective erythropoiesis.

open access: yesBlood Advances, 2021
Luspatercept (Reblozyl) was recently approved for treating patients with transfusion-dependent lower-risk myelodysplastic syndrome (MDS) with ring sideroblasts (RS) and/or SF3B1 mutation who were not eligible for erythropoiesis-stimulating agents (ESAs ...

Embryonal erythropoiesis and aging exploit ferroptosis

open access: yesRedox Biology, 2021
Ferroptosis is a form of regulated cell necrosis, as a consequence of Fe(II)-dependent lipid peroxidation. Although ferroptosis has been linked to cancer cell death, neurodegeneration and reperfusion injury, physiological roles of ferroptosis have not ...

Erythroblastic Island Macrophages Shape Normal Erythropoiesis and Drive Associated Disorders in Erythroid Hematopoietic Diseases

open access: yesFrontiers in Cell and Developmental Biology, 2021
Erythroblastic islands (EBIs), discovered more than 60 years ago, are specialized microenvironments for erythropoiesis. This island consists of a central macrophage with surrounding developing erythroid cells.

Erythropoiesis in health and disease: Distinguishing defective and ineffective erythropoiesis. [PDF]

open access: yesHemasphere
Erythropoiesis is a finely regulated process ensuring continuous red blood cell production to maintain oxygen delivery. Disruptions in this process give rise to defective erythropoiesis, characterized by impaired lineage commitment and progenitor ...

Comprehensive phenotyping of erythropoiesis in human bone marrow: Evaluation of normal and ineffective erythropoiesis

open access: yesAmerican journal of hematology/oncology, 2021
Identification of stage‐specific erythroid cells is critical for studies of normal and disordered human erythropoiesis. While immunophenotypic strategies have previously been developed to identify cells at each stage of terminal erythroid differentiation,

Stage-specific dual function: EZH2 regulates human erythropoiesis by eliciting histone and non-histone methylation

open access: yesHaematologica, 2023
Enhancer of zeste homolog 2 (EZH2) is the lysine methyltransferase of polycomb repressive complex 2 (PRC2) that catalyzes H3K27 tri-methylation. Aberrant expression and loss-of-function mutations of EZH2 have been demonstrated to be tightly associated ...

Increased Reactive Oxygen Species and Cell Cycle Defects Contribute to Anemia in the RASA3 Mutant Mouse Model scat

open access: yesFrontiers in Physiology, 2018
RASA3 is a Ras GTPase activating protein that plays a critical role in blood formation. The autosomal recessive mouse model scat (severe combined anemia and thrombocytopenia) carries a missense mutation in Rasa3.

Research advances in erythrocyte regeneration sources and methods in vitro

open access: yesCell Regeneration, 2018
Erythrocytes (red blood cells, RBCs) facilitate gas exchange in the lungs and transport oxygen to the tissues. The human body must maintain erythrocyte regeneration to support metabolically active cells and tissues.
