Q fever is a zoonotic disease caused by , an obligatory intracellular bacterial pathogen. Like other intracellular pathogens, is able to survive and reproduce within host cells by manipulating host cellular processes. In particular, the relationship between infection and host autophagy, a cellular process involved in degradation and recycling, is of great interest due to its intricate nature. Studies have shown that autophagy can recognize and target intracellular pathogens such as and for degradation, limiting their replication and promoting bacterial clearance. However, can actively manipulate the autophagic pathway to create an intracellular niche, known as the -containing vacuole (CCV), where it can multiply and evade host immune responses. promotes the fusion of CCVs with lysosomes through mechanisms involving virulence factors such as Cig57 and CvpF. This review summarizes the latest findings on the dynamic interaction between host autophagy and infection, highlighting the complex strategies employed by both the bacterium and the host. A better understanding of these mechanisms could provide important insights into the development of novel therapeutic interventions and vaccine strategies against infections.
Q热是一种由 obligatory intracellular bacterial pathogen(一种专性胞内细菌病原体)引起的人畜共患病。与其他胞内病原体一样,obligatory intracellular bacterial pathogen能够通过操纵宿主细胞过程在宿主细胞内存活和繁殖。特别是,由于其复杂的性质,obligatory intracellular bacterial pathogen感染与宿主自噬(一种参与降解和再循环的细胞过程)之间的关系备受关注。研究表明,自噬可以识别并靶向诸如obligatory intracellular bacterial pathogen等胞内病原体进行降解,限制它们的复制并促进细菌清除。然而,obligatory intracellular bacterial pathogen可以积极操纵自噬途径以创建一个胞内生态位,即所谓的含obligatory intracellular bacterial pathogen液泡(CCV),在其中它可以繁殖并逃避宿主免疫反应。obligatory intracellular bacterial pathogen通过涉及诸如Cig57和CvpF等毒力因子的机制促进CCV与溶酶体的融合。本综述总结了关于宿主自噬与obligatory intracellular bacterial pathogen感染之间动态相互作用的最新发现,突出了细菌和宿主所采用的复杂策略。更好地理解这些机制可为开发针对obligatory intracellular bacterial pathogen感染的新型治疗干预措施和疫苗策略提供重要见解。
