树突状细胞(Dendritic cells,DCs)是目前发现的最有效的抗原提呈细胞,在启动和放大先天性及适应性免疫应答中发挥重要的作用.在其整个生命过程中,它的细胞形态、迁移与黏附、抗原捕获及抗原提呈等多方面与细胞骨架的动态重构存在密切的关系.细胞骨架的动态重构是一个由多种细胞骨架蛋白共同参与调节的复杂的结构体系,随着研究的不断深入,人们对这种结构体系的认知越来越清晰.基于这些研究,本文综述了纤维状肌动蛋白(Filamentous actin,F-actin)重构对树突状细胞形态和功能的影响.%Dendritic cells (DCs)are the most potent antigen presenting cells,which play crucial roles in initiating and amplifying both the innate and adaptive immune responses.In DCs' whole life,the dynamics of cytoskeleton is involved in the regulation of their deformation,migration,adhesion,endocytosis and antigen presentation.The cytoskeleton is a complex system and regulated by lots of cytoskeletal proteins.With the research going,our understanding on cytoskeleton system is getting clear.Based on these,we summarized the effects of filamentous actin (F-actin)cytoskeleton remodeling on the morphology and immune functions of DCs.
