Vascular smooth muscle cell (VSMC) migration plays an important role in cardiovascular diseases, including atherosclerotic plaque formation and restenosis after vascular intervention. The mechanisms involved in VSMC migration are complex and have not been fully elucidated. Recently, we discovered a novel interaction, direct binding of active Fyn-paxillin at focal adhesions, which plays an important role in actin stress fiber formation and migration in VSMCs. In this review, we highlight paxillin as an intermediate signaling molecule that mediates actin stress fiber formation and VSMC migration through the Fyn/paxillin/Rho-kinase signaling pathway by directly binding to active Fyn. We also discuss the inhibition of VSMC migration by blocking the active Fyn-paxillin interaction and the potential of this interaction as a therapeutic target for cardiovascular diseases.
