Central post-stroke pain (CPSP) is a chronic neuropathic pain syndrome that commonly occurs after cerebral stroke, and it severely impairs the daily activities of stroke patients. A number of fundamental and clinical studies support the theory that CPSP is mainly caused by ischemic and hemorrhagic injury of the spinal-thalamic-cortical neural pathway. However, the underlying reasons of CPSP genesis and development are far from clear. In recent years, the majority of research focused on microglia, the main resident immune cells of the central nervous system, which highlighted its critical role in the regulation of CPSP. The present article concentrated on exciting discoveries of microglia in mediating CPSP from the perspectives of their bioactive factors, cellular receptors, and signaling pathways, in order to offer a convenient and easy-to-digest overview. In addition, the potential and challenges of several agents in clinical translation of CPSP treatment was discussed based on recent preclinical studies.
