沙门氏菌会导致人类和动物的疾病,从轻微的自限性胃肠炎到可能危及生命的伤寒。沙门氏菌病仍然是全球发病率和死亡率的一个重要原因,因此在世界范围内造成了巨大的社会经济负担。所有致病沙门氏菌菌株的一个关键特性是能够入侵非吞噬宿主细胞。这种侵袭性的主要决定因素是3型分泌系统(T3SS),这是一种将毒力效应蛋白直接注入目标宿主细胞的分子注射器。这些效应器协同操纵多个宿主细胞信号通路,以驱动病原体内化。沙门氏菌不仅依赖于这些注射的效应器,还使用其他几种不依赖T3SS的机制来进入宿主细胞。本文综述了目前对沙门氏菌侵袭细胞的方法的认识,重点介绍了沙门氏菌必须协同利用宿主信号网络才能实现其目标。
Salmonella causes disease in humans and animals ranging from mild self-limiting gastroenteritis to potentially life-threatening typhoid fever. Salmonellosis remains a considerable cause of morbidity and mortality globally, and hence imposes a huge socio-economic burden worldwide. A key property of all pathogenic Salmonella strains is the ability to invade non-phagocytic host cells. The major determinant of this invasiveness is a Type 3 Secretion System (T3SS), a molecular syringe that injects virulence effector proteins directly into target host cells. These effectors cooperatively manipulate multiple host cell signaling pathways to drive pathogen internalization. Salmonella does not only rely on these injected effectors, but also uses several other T3SS-independent mechanisms to gain entry into host cells. This review summarizes our current understanding of the methods used by Salmonella for cell invasion, with a focus on the host signaling networks that must be coordinately exploited for the pathogen to achieve its goal.
