Neuropathic pain (NP) is a pathological state caused by damage or disease to the somatosensory nervous system. Programmed cell death (PCD) is an orderly process of cell death regulated by both intrinsic signals and external stimuli. In recent years, an increasing number of studies have shown that PCD plays a key regulatory role in the pathogenesis of NP. This article reviews the molecular mechanisms of various types of PCD and their specific roles in NP, in order to provide new research directions for the prevention, diagnosis, and treatment of NP.
