Abstract: The adhesion and invasion into eukaryotic cells are major steps in bacterial pathogenesis. In order to further study the entire process and molecular mechanisms of bacteria invading non-phagocytic cells,we reviewed the bacterial adhesion and invasion of non-phagocytic cells and the regulatory mechanisms of focal adhesion kinase(FAK)in this process. During the adhesion process,the interaction of surface adhesive molecules and special structures of bacteria with receptors of host cells activates the FAK to regulate the cytoskeletal rearrangement through FAK/Src-Cortactin-Arp2/3 and FAK/PI3K-Rac pathways,which promotes the bacterial invasion of non-phagocytic cells.

Key words: bacteria, adhesion, invasion, focal adhesion kinase, signaling pathway
