自噬是一种保存在真核生物中的溶酶体循环过程,它通过降解和循环蛋白质、脂类和碳水化合物来维持细胞在应激和饥饿条件下的动态平衡,最终增加营养的可获得性。自噬的另一个功能是检测、捕获和摧毁入侵的微生物,如病毒、细菌和原生动物,提供自噬在先天免疫中的作用。然而,许多细胞内的病原体已经发展出避免异种吞噬的机制,并已经进化出策略来利用选定的自噬过程来经历它们的细胞内生命周期。本文就胞内致病菌Francisella spp.的分子机制作一综述。和布鲁氏菌属。操纵自噬途径的组成部分,促进弗朗西斯氏菌的胞浆生长,并促进布鲁氏菌的细胞出口和细胞间传播。这些例子突显了成功的、高度传染性的细菌病原体如何避免或颠覆宿主自噬机制,通常用于维持真核细胞的动态平衡。
Autophagy is a lysosomal recycling process conserved in eukaryotes, which maintains cellular homeostasis during stress and starvation conditions by degrading and recycling proteins, lipids and carbohydrates, ultimately increasing nutrient availability. An additional function of autophagy, termed xenophagy, is to detect, capture and destroy invading microorganisms, such as viruses, bacteria and protozoa, providing autophagy with a role in innate immunity. Many intracellular pathogens have however developed mechanisms to avoid xenophagy, and have evolved strategies to take advantage of select autophagic processes to undergo their intracellular lifecycle. This review article will discuss the molecular mechanisms used by the intracellular bacterial pathogens Francisella spp. and Brucella spp. to manipulate components of the autophagic pathway, promoting cytosolic growth in the case of Francisella spp., and facilitating cellular egress and cell-to-cell spread in the case of Brucella spp. These examples highlight how successful, highly infectious bacterial pathogens avoid or subvert host autophagy mechanisms normally employed to maintain eukaryotic homeostasis.
