细菌鞭毛在生理活动中的作用

The functions of bacterial flagella in physiological activity

鞭毛是细菌主要的运动器官,细菌通过鞭毛运动实现趋化性。随着研究的不断深入,研究人员发现鞭毛具有很多其他功能。现综述细菌鞭毛在生理活动中的作用,包括鞭毛介导的运动和趋化性,鞭毛的致病性、抗原性与免疫原性,以及鞭毛与冷适应机制的关系,并结合实验室研究方向,对细菌鞭毛相关的冷适应机制做出了展望。

Flagella are the major motility organs of bacteria, and bacteria can achieve chemotaxis through flagella- mediated movement. However, as research continuous, many other functions of flagella have been discovered. This review summarizes the functions of bacterial flagella in physiological activity, including flagella-mediated motility and chemotaxis, flagella pathogenicity, antigenicity and immunogenicity, and the relationship between flagella and cold-adaptation mechanisms. Combined with our own research, prospects about the cold-adaptation mechanisms associated with bacterial flagella are proposed in this paper.
