Phagocytes are considered the most important effector cells in the immune response against fungal infections. To exert their role, they must recognize the invading fungi, internalise, and kill them within the phagosome. Major advances in the field have elucidated the roles of pattern-recognition receptors in the innate immunity sensing and the importance of reactive oxygen and nitrogen species in intracellular killing of fungi. Surprising exit mechanisms for intracellular pathogens and extracellular traps have also been discovered. These and several other recent breakthroughs in our understanding of the mechanisms used by phagocytes to kill fungal pathogens are reviewed in this work.
吞噬细胞被认为是抗真菌感染免疫反应中最重要的效应细胞。为发挥其作用,它们必须识别入侵的真菌,将其内化,并在吞噬体内将其杀死。该领域的重大进展阐明了模式识别受体在固有免疫感知中的作用,以及活性氧和氮物质在细胞内杀灭真菌中的重要性。还发现了细胞内病原体和细胞外陷阱的惊人排出机制。本文综述了这些以及我们对吞噬细胞杀灭真菌病原体所使用机制理解方面的其他一些最新突破。
