一段时间以来,我的实验室一直对铁的影响感兴趣,铁是微生物病原体及其哺乳动物宿主所必需的营养素,对传染病的过程至关重要。我们的研究表明,螯合或运输铁的宿主分子表达的改变可以对病原体生长产生直接影响,也可以对正常免疫反应的能力产生影响。我们已经阐明了其中一些观察结果的机制基础,并开始将我们的发现应用于控制炎症和铁代谢异常的策略中。我将在这里回顾一下我们所了解的铁和免疫力之间的相互作用,并讨论我们所获得的信息的含义。
My laboratory has been interested for some time in the influence of iron, a nutrient that is essential for both microbial pathogens and their mammalian hosts, on the course of infectious disease. Our studies indicate that alterations in the expression of host molecules that sequester or transport iron can have direct effects on pathogen growth and can also have an impact on the ability to mount normal immune responses. We have elucidated the mechanistic basis for some of these observations, and have started to apply our findings in strategies to control abnormalities of inflammation and iron metabolism. I will review here what we have learned about the interactions between iron and immunity and discuss the implications of the information that we have acquired.
