铁是几乎所有生物体的必需物,它不仅用于合成某些酶类及细胞色素,参与机体代谢,而且也有助于调节机体的免疫功能。有证据表明,淋巴细胞的代谢与分化、嗜中性白细胞的杀菌作用,都需要有足量的铁,本文基于已有的资料,将铁对机体免疫系统的影响作一综述。一、铁缺乏对免疫系统的影响铁缺乏可引起大量患者免疫功能障碍,动物实验表明缺铁可导致对感染的敏感性增高, Iron is required for almost all organisms. It is not only used for the synthesis of certain enzymes and cytochromes but also for the metabolism of the body. It also helps to regulate the body’s immune function. There is evidence that the metabolism and differentiation of lymphocytes, the neutrophil bactericidal effect, all need a sufficient amount of iron, based on the available information, this article will review the impact of iron on the immune system. First, iron deficiency on the immune system Iron deficiency can cause a large number of patients with immune dysfunction, animal experiments show that iron deficiency can lead to increased susceptibility to infection,
