细菌粘附到宿主上皮细胞表面是细菌引起机体感染的重要始动因素。细菌表面的特异识别分子——配体(ligand)和宿主上皮细胞表面对应的识别分子——受体(receptor)是细菌实现粘附的物质基础,二者互相紧密粘附结合,有利于细菌定居、繁殖和致病。本文仅就涉及细菌粘附的某些细胞分子生物学研究的一些进展作简要综述。 Bacterial adhesion to the surface of host epithelial cells is an important initiating factor for bacterial infection in the body. Specific recognition molecules on the bacterial surface - the ligand and the corresponding recognition molecule on the surface of the host epithelial cells - the receptor is the material basis for the bacteria to adhere, which are closely adhered to each other and conducive to bacterial colonization , Breeding and disease. This article briefly reviews some of the advances in molecular cell biology that involve bacterial adhesion.
