新型隐球菌是一种机会性真菌病原体,是免疫功能低下个体的主要死亡原因。这种酵母与宿主吞噬细胞的相互作用对疾病的结果至关重要,并且C。新生儿具有一系列调节这些过程的因子。隐球菌感染开始于感染性颗粒沉积到肺中,其中真菌细胞部署各种抗吞噬因子以抵抗宿主细胞的内化。如果隐球菌仍然被吞噬,它们可以通过调节它们所处的吞噬溶酶体环境在宿主细胞内存活和增殖。最后,隐球菌细胞可能通过宿主细胞裂解、非裂解性胞吐作用或侧向细胞间转移而逃离吞噬细胞。C.新生菌和宿主吞噬细胞也影响这种病原体向脑的传播,在脑中它可能穿过血脑屏障并引起通常致命的脑膜脑炎。在这篇综述中,我们强调了关键的隐球菌因子参与不同阶段的隐球菌-宿主相互作用和发病机制。
Cryptococcus neoformans is an opportunistic fungal pathogen and a leading cause of death in immunocompromised individuals. The interactions of this yeast with host phagocytes are critical to disease outcome, and C. neoformans is equipped with an array of factors to modulate these processes. Cryptococcal infection begins with the deposition of infectious particles into the lungs, where the fungal cells deploy various antiphagocytic factors to resist internalization by host cells. If the cryptococci are still engulfed, they can survive and proliferate within host cells by modulating the phagolysosome environment in which they reside. Lastly, cryptococcal cells may escape from phagocytes by host cell lysis, nonlytic exocytosis, or lateral cell-to-cell transfer. The interactions between C. neoformans and host phagocytes also influence the dissemination of this pathogen to the brain, where it may cross the blood-brain barrier and cause an often-fatal meningoencephalitis. In this review, we highlight key cryptococcal factors involved in various stages of cryptococcal-host interaction and pathogenesis.
