空肠弯曲杆菌是一种螺旋形革兰氏阴性病原体,是全球人类胃肠道食源性疾病的常见原因。C.空肠感染的范围从轻度到严重的空肠炎,以及一些其他并发症,包括反应性关节炎和格林-巴利综合征。这篇综述文章重点介绍了各种C。jejuni致病因子,宿主细胞决定簇,以及参与人类宿主细胞侵袭的信号传导机制及其在C.空肠介导的疾病。提出了一个模型,概述了各种重要的相互作用的C。空肠与肠上皮细胞,我们讨论了赞成和反对的“拉链”的“触发”机制的入侵。未来的工作应该澄清一些先前确定的因素的矛盾作用,并应该确定和表征新的毒力决定因素,这对于为该病原体致病策略的多样性提供新的见解至关重要。
Campylobacter jejuni, a spiral-shaped Gram-negative pathogen, is a highly frequent cause of gastrointestinal foodborne illness in humans worldwide. Clinical outcome of C. jejuni infections ranges from mild to severe diarrheal disease, and some other complications including reactive arthritis and Guillain–Barré syndrome. This review article highlights various C. jejuni pathogenicity factors, host cell determinants, and proposed signaling mechanisms involved in human host cell invasion and their potential role in the development of C. jejuni-mediated disease. A model is presented which outlines the various important interactions of C. jejuni with the intestinal epithelium, and we discuss the pro’s and con’s for the “zipper” over the “trigger” mechanism of invasion. Future work should clarify the contradictory role of some previously identified factors, and should identify and characterize novel virulence determinants, which are crucial to provide fresh insights into the diversity of strategies employed by this pathogen to cause disease.
