Magnesium (Mg) is an essential mineral for the functioning and maintenance of the body. Disturbances in Mg intracellular homeostasis result in cell-membrane modification, an increase in oxidative stress, alteration in the proliferation mechanism, differentiation, and apoptosis. Mg deficiency often results in inflammation, with activation of inflammatory pathways and increased production of proinflammatory cytokines by immune cells. Immune cells and others that make up the blood system are from hematopoietic tissue in the bone marrow. The hematopoietic tissue is a tissue with high indices of renovation, and Mg has a pivotal role in the cell replication process, as well as DNA and RNA synthesis. However, the impact of the intra- and extracellular disturbance of Mg homeostasis on the hematopoietic tissue is little explored. This review deals specifically with the physiological requirements of Mg on hematopoiesis, showing various studies related to the physiological requirements and the effects of deficiency or excess of this mineral on the hematopoiesis regulation, as well as on the specific process of erythropoiesis, granulopoiesis, lymphopoiesis, and thrombopoiesis. The literature selected includes studies in vitro, in animal models, and in humans, giving details about the impact that alterations of Mg homeostasis can have on hematopoietic cells and hematopoietic tissue.
镁(Mg)是维持身体正常功能和健康所必需的矿物质。镁细胞内稳态的紊乱会导致细胞膜的改变、氧化应激的增加、增殖机制、分化和凋亡的改变。镁缺乏常导致炎症,激活炎症途径和免疫细胞产生更多的促炎细胞因子。构成血液系统的免疫细胞和其他细胞都来自骨髓中的造血组织。造血组织是一个具有高更新指数的组织,镁在细胞复制过程中以及 DNA 和 RNA 合成中起着关键作用。然而,细胞内外镁稳态紊乱对造血组织的影响还没有得到充分的研究。本综述专门讨论了镁对造血的生理需求,展示了各种与生理需求相关的研究,以及缺乏或过量这种矿物质对造血调节、红细胞生成、粒细胞生成、淋巴生成和血小板生成等具体过程的影响。所选择的文献包括体外研究、动物模型研究和人体研究,详细介绍了镁稳态改变对造血细胞和造血组织的影响。
