单核细胞增生李斯特菌已成为一个非常容易对付的病原体,解剖细胞生物学的基本方面,细胞内发病机制,先天性和获得性免疫。为了维持其细胞内的生活方式,L。单核细胞增生已经进化出许多机制来利用宿主过程在细胞间生长和扩散而不损伤宿主细胞。孔形成蛋白质Escherichiolysin O介导从宿主液泡中逃逸,并利用多种故障安全机制来避免对感染细胞造成毒性。一旦进入细胞质,L。单核细胞增多症ActA蛋白募集宿主细胞Arp 2/3复合物并使能/血管舒张剂刺激的磷蛋白家族成员介导有效的基于肌动蛋白的运动,从而将细菌推进到邻近细胞中。这些过程中的任何一个的改变都会显著降低细菌在体内建立生产性感染的能力。
Listeria monocytogenes has emerged as a remarkably tractable pathogen to dissect basic aspects of cell biology, intracellular pathogenesis, and innate and acquired immunity. In order to maintain its intracellular lifestyle, L. monocytogenes has evolved a number of mechanisms to exploit host processes to grow and spread cell to cell without damaging the host cell. The pore-forming protein listeriolysin O mediates escape from host vacuoles and utilizes multiple fail-safe mechanisms to avoid causing toxicity to infected cells. Once in the cytosol, the L. monocytogenes ActA protein recruits host cell Arp2/3 complexes and enabled/vasodilator-stimulated phosphoprotein family members to mediate efficient actin-based motility, thereby propelling the bacteria into neighboring cells. Alteration in any of these processes dramatically reduces the ability of the bacteria to establish a productive infection in vivo.
