铁是人体和病原微生物的必需营养素。由于它能够以两种氧化态之一存在,铁是多种细胞过程(包括呼吸和DNA复制)的理想氧化还原催化剂。然而,铁的氧化还原电位也有助于其毒性,因此必须仔细控制铁的浓度和分布。考虑到几乎所有人类病原体对铁的绝对需求,先天免疫系统的一个重要方面是在称为营养免疫的过程中限制铁对入侵微生物的可用性。因此,成功的人类病原体必须具有绕过营养免疫的机制,以引起疾病。在这篇综述中,我们讨论了在感染环境中铁代谢的调节,并描述了人类病原体克服铁抑制防御的策略。
Iron is an essential nutrient for both humans and pathogenic microbes. Because of its ability to exist in one of two oxidation states, iron is an ideal redox catalyst for diverse cellular processes including respiration and DNA replication. However, the redox potential of iron also contributes to its toxicity, thus iron concentration and distribution must be carefully controlled. Given the absolute requirement for iron by virtually all human pathogens, an important facet of the innate immune system is to limit iron availability to invading microbes in a process termed nutritional immunity. Successful human pathogens must therefore possess mechanisms to circumvent nutritional immunity in order to cause disease. In this review, we discuss regulation of iron metabolism in the setting of infection and delineate strategies used by human pathogens to overcome iron-withholding defenses.
