Abstract

S100A4 participates in inflammation and immune reactions in the central nervous system and is involved in the pathogenesis of multiple neurological disorders. It can affect the functions of astrocytes, microglia, infiltrating cells and neurons and further modulates neuronal plasticity and survival in the central nervous system. However, its impact on astrocyte phenotypes and neuropathic pain and the intrinsic mechanisms involved remain poorly understood. Here, we showed that...
