Int J Mol Sci 2024; 25:5814. [PMID: 38892001 PMCID: PMC11172562 DOI: 10.3390/ijms25115814] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2024] [Revised: 05/21/2024] [Accepted: 05/22/2024] [Indexed: 06/21/2024] Open
Abstract
The deformability of red blood cells (RBCs), expressing their ability to change their shape as a function of flow-induced shear stress, allows them to optimize oxygen delivery to the tissues and minimize their resistance to flow, especially in microcirculation. During physiological aging and blood storage, or under external stimulations, RBCs undergo metabolic and structural alterations, one of which is hemoglobin (Hb) redistribution between the cytosol and the membrane. Consequently, part of the Hb may attach to the cell membrane, and although this process is reversible, the increase in membrane-bound Hb (MBHb) can affect the cell's mechanical properties and deformability in particular. In the present study, we examined the correlation between the MBHb levels, determined by mass spectroscopy, and the cell deformability, determined by image analysis. Six hemoglobin subunits were found attached to the RBC membranes. The cell deformability was negatively correlated with the level of four subunits, with a highly significant inter-correlation between them. These data suggest that the decrease in RBC deformability results from Hb redistribution between the cytosol and the cell membrane and the respective Hb interaction with the cell membrane.

Abstract
Researchers have attempted to generate transfusable oxygen carriers to mitigate RBC supply shortages. In vitro generation of RBCs using stem cells such as hematopoietic stem and progenitor cells (HSPCs), embryonic stem cells (ESCs), and induced pluripotent stem cells (iPSCs) has shown promise. Specifically, the limited supplies of HSPCs and ethical issues with ESCs make iPSCs the most promising candidate for in vitro RBC generation. However, researchers have encountered some major challenges when using iPSCs to produce transfusable RBC products, such as enucleation and RBC maturation. In addition, it has proven difficult to manufacture these products on a large scale. In this review, we provide a brief overview of erythropoiesis and examine endeavors to recapitulate erythropoiesis in vitro using various cell sources. Furthermore, we explore the current obstacles and potential solutions aimed at enabling the large-scale production of transfusable RBCs in vitro.

Abstract
The membrane-bound hemoglobin (Hb) fraction impacts red blood cell (RBC) rheology and metabolism. Therefore, Hb-RBC membrane interactions are precisely controlled. For instance, the signaling function of membrane-bound deoxy-Hb and the structure of the docking sites in the cytosolic domain of the anion exchanger 1 (AE-1) protein are well documented; however, much less is known about the interaction of Hb variants with the erythrocyte's membrane. Here, we identified factors other than O2 availability that control Hb abundance in the membrane-bound fraction and the possible variant-specific binding selectivity of Hb to the membrane. We show that depletion of extracellular Ca2+ by chelators, or its omission from the extracellular medium, leads to membrane-bound Hb release into the cytosol. The removal of extracellular Ca2+ further triggers the redistribution of HbA0 and HbA2 variants between the membrane and the cytosol in favor of membrane-bound HbA2. Both effects are reversible and are no longer observed upon reintroduction of Ca2+ into the extracellular medium. Fluctuations of cytosolic Ca2+ also impact the pre-membrane Hb pool, resulting in the massive transfer of Hb to the cellular cytosol. We hypothesize that AE-1 is the specific membrane target and discuss the physiological outcomes and possible clinical implications of the Ca2+ regulation of the intracellular Hb distribution.

Abstract
Six hemoglobin isoforms were identified in the peripheral blood of male Wistar rats by PAAG electrophoresis. Erythrocytes can be separated into 6 fractions by fractional centrifugation; the fractions differ by the content of reticulocytes and cells with fetal hemoglobin. Cells in each fraction contain one light and one heavy hemoglobin isoforms, and their combination is specific to each fraction. Changes in the hemoglobin isoforms in the whole blood in case of blood loss can be associated with changes in physical and chemical properties of circulating erythrocytes, as well as with the formation of various cell populations resulting from activated erythropoiesis.

Abstract
In this paper, cadmium (Cd) stress tests were performed on Eisenia fetida in sterile artificial soil, and its regulatory mechanism between microbial communities in vivo and in vitro after Cd stress was explored. In the test, 0, 50, 100, 125, 250 and 500 mg kg-1 Cd stress concentrations were implemented. After long-term and short-term stress, the microbes in the earthworms and the soil were cultured with ECO plates. The data statistics of carbon source utilization intensity were carried out using the method developed by our team. CCA was scientifically integrated into TOPSIS to establish a new data analysis model to find the regulatory nodes after stress (Ning et al., 2020). Macro gene sequencing technology revealed that the species with the highest absolute abundance in the microbial communities in vivo and in vitro were all unnamed new species. It was confirmed that the HBA gene, NEUROD1 gene and ABCA3 gene were the regulatory genes of the microbial community in the earthworms under Cd stress, while the TC.FEV.OM gene and cheBR gene were the main regulatory genes of the microbial community in the soil. These results provide a scientific and theoretical reference and model basis for the bioremediation of Cd-contaminated soil and the detoxification mechanism of earthworms.

Abstract
Aggregation of hemoglobin is implicated in the presentation of diseases like sickle cell disease and thalassemia. Hallmark of the disease being imbalance in the production of globin chains leading to aggregation of excess globin chains and aberrant hemoglobins associated with the disease, broadly categorized as hemoglobinopathy. We have studied thermal aggregation of hemoglobin at 70 °C and pH 6.5 using light scattering, flow cytometry and optical microscopy and tried to investigate effects of few abundant soluble metal ions on such aggregation. Our study indicate that only iron, both in Fe2+ and Fe3+ forms, could inhibit hemoglobin aggregation and the extent of inhibition was 60% in presence of 100 mgL-1 FeCl3. Similar effect was not seen in lysozyme aggregation. Metal ions such as, Cu2+, Zn2+ and Ni2+ also did not have any significant effects on hemoglobin aggregation. Results show this important chaperone like behavior of free iron affecting the kinetics and yield of the aggregation process which could have important consequence in the extent of severity of such hematological diseases.

Abstract
Under pathological conditions, such as sickle cell disease and malaria, heme concentration increases considerably, and it induces membrane damage. As sickled and normal erythrocytes contain high cholesterol: phospholipid ratio, we investigated the role of lipid composition, chain length, and unsaturation on the partitioning and leakage of hemin in phospholipid vesicles. To establish structure-activity relationship in membrane damage, experiments with two other analogues, protoporphyrin-IX and hematoporphyrin (HP) were also carried out. Hemin and its analogues localize differently in membranes and exhibit distinct roles in partitioning, leakage and fusion. Hemin and HP trigger more leakage in the presence of aminophospholipids, whereas cholesterol buffers the destabilizing effect remarkably. Inhibition of fusion by hemin further suggests its unexplored and important role in membrane trafficking, particularly under diseased conditions.

Abstract
Extracellular vesicles (EVs) are currently in scientific focus, as they have great potential to revolutionize the diagnosis and therapy of various diseases. However, numerous aspects of these species are still poorly understood, and thus, additional insight into their molecular-level properties, membrane-protein interactions, and membrane rigidity is still needed. We here demonstrate the use of red-blood-cell-derived EVs (REVs) that polarized light spectroscopy techniques, linear and circular dichroism, can provide molecular-level structural information on these systems. Flow-linear dichroism (flow-LD) measurements show that EVs can be oriented by shear force and indicate that hemoglobin molecules are associated to the lipid bilayer in freshly released REVs. During storage, this interaction ceases; this is coupled to major protein conformational changes relative to the initial state. Further on, the degree of orientation gives insight into vesicle rigidity, which decreases in time parallel to changes in protein conformation. Overall, we propose that both linear dichroism and circular dichroism spectroscopy can provide simple, rapid, yet efficient ways to track changes in the membrane-protein interactions of EV components at the molecular level, which may also give insight into processes occurring during vesiculation.

Abstract
Hemoglobin (Hb) E (β26 Glu→Lys) is the most common abnormal hemoglobin (Hb) variant in the world. Homozygotes for HbE are mildly thalassemic as a result of the alternate splice mutation and present with a benign clinical picture (microcytic and mildly anemic) with rare clinical symptoms. Given that the human red blood cell (RBC) contains both HbE and excess α-chains along with minor hemoglobins, the consequence of HbE alone on RBC pathophysiology has not been elucidated. This becomes critical for the highly morbid β(E)-thalassemia disease. We have generated transgenic mice exclusively expressing human HbE (HbEKO) that exhibit the known aberrant splicing of β(E) globin mRNA, but are essentially non-thalassemic as demonstrated by RBC α/β (human) globin chain synthesis. These mice exhibit hematological characteristics similar to presentations in human EE individuals: microcytic RBC with low MCV and MCH but normal MCHC; target RBC; mild anemia with low Hb, HCT and mildly elevated reticulocyte levels and decreased osmotic fragility, indicating altered RBC surface area to volume ratio. These alterations are correlated with a mild RBC oxidative stress indicated by enhanced membrane lipid peroxidation, elevated zinc protoporphyrin levels, and by small but significant changes in cardiac function. The C57 (background) mouse and full KO mouse models expressing HbE with the presence of HbS or HbA are used as controls. In select cases, the HbA full KO mouse model is compared but found to be limited due to its RBC thalassemic characteristics. Since the HbEKO mouse RBC lacks an abundance of excess α-chains that would approximate a mouse thalassemia (or a human thalassemia), the results indicate that the observed in vivo RBC mild oxidative stress arises, at least in part, from the molecular consequences of the HbE mutation.

Abstract
In this paper, we aimed to introduce a newly established red blood cells (RBCs) electrophoresis method hemoglobin release test (HRT) and tried to determine its significance. Human blood samples from beta-thalassemia patients and healthy controls were analyzed with HRT, which was carried out on starch-agarose mixed gel. First, the whole blood samples were electrophoresed for 2 h, then paused for 15 min and ran for 15 min by turns. This "pause-run-pause" experiment was performed for several turns and the total electrophoresis time lasted for about 6 h. The results showed that some other hemoglobin (Hb) components were released from the origin of each sample during the HRT, and the samples from beta-thalassemia patients released more Hb than the healthy controls. This finding demonstrates that Hb may exist differently associated in RBCs, and it may have an important theoretical and clinical significance in Hb and RBC research.
