Background: Integrin β1, as a member of the adhesion molecule family, is widely distributed in many kinds of cells and participates in multiple biological functions of the nervous system, including cytoskeleton reorganization, axon growth, and inflammatory injury. Summary: After nervous system injury, integrin β1 expressed by microglia is mainly involved in promoting inflammatory damage; integrin β1 expressed by astrocytes plays an important role in axon regeneration; integrin β1 expressed by endothelial cells mainly participates in vascular remodeling. We concluded that the function of integrin β1 depends on the location of the receptor cells. The mechanism of integrin β1, which is involved in the inflammatory response of immune regulatory cells and affects the axonal regeneration of neuronal cells, is the key to explore the repair after nervous system injury. The development of drugs targeting integrin β1 is expected to bring a breakthrough in the treatment of nervous system injury. Key Messages: This paper expounds the important role of integrin β1 in neurons of the nervous system and emphasizes the central role of integrin β1 in regulating non-neuronal cells after nervous system damage.
