Special Issue Information

Dear Colleagues,

NGS (Next Generation Sequencing) technologies have provided important insights into the molecular mechanisms of normal erythropoiesis and homeostasis, as well as related human diseases. Indeed, the widespread availability of new technologies has transformed the way red blood cell disorders are diagnosed, studied, and treated.

From a diagnostic standpoint, genetic testing has become the advanced system for the differential diagnosis of patients with red blood cell disorders such as inherited anemia. From a research perspective, the use of genomic applications has allowed the identification of many new causative genes associated with red blood cell disorders. From a therapeutic perspective, the use of gene therapy and genome editing technologies represents the present and future of red blood cell disease treatment. Gene therapy options have been developed and introduced into clinical practice for diseases such as beta-thalassemia and hemoglobinopathies, while others are in the preclinical stages, such as Diamond Blackfan anemia and erythrocyte enzyme disorders.

This Special Issue in IJMS on “Molecular Genetics and Genomics of Red Blood Cells” will provide an overview of the novel molecular methods and the forefront techniques in the field of genetics and genomics of red blood cells.

Mouse erythropoiesis is a multifaceted process involving the intricate interplay of proliferation, differentiation, and maturation of erythroid cells, leading to significant changes in their transcriptomic and proteomic profiles. While the immunoregulatory role of murine erythroid cells has been recognized historically, modern investigative techniques have been sparingly applied to decipher their functions. To address this gap, our study sought to comprehensively characterize mouse erythroid cells through contemporary transcriptomic and proteomic approaches. By evaluating CD71 and Ter-119 as sorting markers for murine erythroid cells and employing bulk NanoString transcriptomics, we discerned distinctive gene expression profiles between bone marrow and fetal liver-derived erythroid cells. Additionally, leveraging flow cytometry, we assessed the surface expression of CD44, CD45, CD71, and Ter-119 on normal and phenylhydrazine-induced hemolytic anemia mouse bone marrow and splenic erythroid cells. Key findings emerged: firstly, the utilization of CD71 for cell sorting yielded comparatively impure erythroid cell populations compared to Ter-119; secondly, discernible differences in immunoregulatory molecule expression were evident between erythroid cells from mouse bone marrow and fetal liver; thirdly, two discrete branches of mouse erythropoiesis were identified based on CD45 expression: CD45-negative and CD45-positive, which had been altered differently in response to phenylhydrazine. Our deductions underscore (1) Ter-119’s superiority over CD71 as a murine erythroid cell sorting marker, (2) the potential of erythroid cells in murine antimicrobial immunity, and (3) the importance of investigating CD45-positive and CD45-negative murine erythroid cells separately and in further detail in future studies.
