Background/objectives: CD71 erythroid cells (CECs) are immature red blood cells (proerythroblasts, erythroblasts, and reticulocytes). CECs play an important role in the development of sepsis and cancer by causing immunosuppression. We examined the CEC levels in the peripheral blood of beta thalassemia (βThal) patients and investigated the relationship between CECs and the clinical status of the patients, especially splenectomy.
Methods: Sixty-eight patients with βThal (46 splenectomized and 22 nonsplenectomized) and 15 healthy controls were included in this study. The hemogram parameters, ferritin, and CECs (flow cytometry method) were measured.
Results: It was observed that the CEC level in the patient group was significantly higher than the control group (p < 0.05). CEC levels were found to be significantly higher in patients with splenectomy than in patients with nonsplenectomy (p < 0.05). CEC levels were higher in patients with nontransfusion-dependent βT (NTD-βThal) than in patients with transfusion-dependent βT (TD-βThal) (p < 0.05). CEC levels were found to be significantly higher in patients with splenectomy than in patients with nonsplenectomy in both TD-βThal and NTD-βThal groups (p < 0.05). There was a moderate-negative correlation was detected between CECs and Hb levels (r = -0.467; p < 0.05).
Conclusions: High CEC levels in βThal patients develop as a result of ineffective erythropoiesis. We think that keeping CEC levels under control is important for prognosis, especially in patients with splenectomy.

Alpha-Synuclein Inhibition Promotes Erythropoiesis by Affecting Methylation Modifications of Fructose and Mannose Metabolism.

Article Synopsis
- α-synuclein (α-syn) is primarily found in red blood cells (erythrocytes), but its specific role in the production of these cells (erythropoiesis) is not well understood.
- Researchers cultured erythroid cells from human umbilical cord progenitors and found that inhibiting α-syn increased erythropoiesis, as shown by changes in important surface markers and enzyme methylation.
- The study also identified shifts in cellular metabolism, indicating that α-syn functions as a regulator of methylation that influences enzymes in fructose and mannose metabolism, thereby playing a crucial role in the formation of red blood cells.

Differentiation therapy is an alternative strategy used in treating chronic myelogenous leukemia to induce the differentiation of immature or cancerous cells toward mature cells and inhibit tumor cell proliferation. We aimed to explore N-glycans' roles in erythroid differentiation using the sodium butyrate (NaBu)-induced model of K562 cells (WT/NaBu cells). Here, using lectin blot, flow cytometry, real-time PCR, and mass spectrometry analyses, we demonstrated that the mRNA levels of N-acetylglucosaminyltransferase Ⅲ ((encoded by the MGAT3 gene) and its product (bisected N-glycans) were significantly increased during erythroid differentiation.

Article Synopsis
- Ineffective erythropoiesis (IE) leads to anemia in beta-thalassemia, characterized by increased erythroblast proliferation without proper differentiation, resulting in immature red blood cells (RBCs).
- The study investigates the role of microRNA-155 (miR-155) in beta-thalassemia, focusing on its expression in erythroid cells from thalassemic bone marrow and its effects on cell differentiation and proliferation.
- Results show that miR-155 is upregulated during erythropoiesis in thalassemic mice, and manipulating its expression alters erythroid cell proliferation and differentiation, suggesting its potential significance in managing thalassemia-related anemia.
The development of committed erythroid progenitors and their continued maturation into mature erythrocytes requires the cytokine erythropoietin (Epo). Here, we describe the immunophenotypic identification of a unique Epo-dependent colony-forming unit-erythroid (CFU-E) cell subtype that forms during early erythropoiesis (EE). This previously undescribed CFU-E subtype, termed late-CFU-E (lateC), lacks surface expression of the characteristic erythroid marker CD235a (glycophorin A) but has high levels of CD71 and CD105.

Article Synopsis
- - Autoimmune hemolytic anemia (AIHA) is a disease caused by the body's immune system attacking red blood cells, leading to rapid hemolysis and anemia, with varying onset based on triggers.
- - Desidustat, a medication primarily used for anemia related to chronic kidney disease, was tested in a study on mice with AIHA and showed positive results, improving levels of hemoglobin and red blood cells while reducing white blood cells and oxidative stress.
- - The treatment with desidustat enhanced erythropoiesis (the production of red blood cells) and prevented antibody-mediated damage to red blood cells, suggesting that desidustat could be an effective option for treating AIHA.
