铁、锌、铜和锰等过渡金属对从细菌到哺乳动物的生物体的生长和发育至关重要。许多研究都集中在细菌和真菌感染期间铁的可用性的影响,越来越多的证据表明,铜也参与微生物的发病机制。铜不仅是特定微生物酶的重要辅助因子,而且最近的几项研究也强烈表明铜用于限制体内病原体的生长。在这里,我们回顾了动物使用铜作为抗微生物武器的证据,反过来,微生物已经开发出抵消铜毒性作用的机制。
Transition metals such as iron, zinc, copper and manganese are essential for the growth and development of organisms ranging from bacteria to mammals. Numerous studies have focused on the impact of iron availability during bacterial and fungal infections, and increasing evidence suggests that copper is also involved in microbial pathogenesis. Not only is copper an essential co-factor for specific microbial enzymes, but several recent studies also strongly suggest that copper is used to restrict pathogen growth in vivo. Here, we review evidence that animals use copper as an anti-microbial weapon and, in turn, microbes have developed mechanisms to counteract the toxic effects of copper.
