Nerve injury and nerve pain are common diseases caused by neuroinflammation. Numerous studies have shown that the activation of NLRP3 (nod-like receptor family, pyrin domain-containing 3) inflammasome is involved in a various inflammatory response, such as Alzheimer's disease, diabetes, nerve damage and other diseases. The NLRP3 inflammasome is a complex containing NLRP3 protein, ASC (apoptosis-associated speckle-like protein), and pro-caspase-1, which is highly expressed and activated to promote the secretion of IL-1β and IL-18 in response to the stimulation of danger-associated molecular patterns (DAMPs) and pathogen-associated molecular patterns (PAMPs) in immune cells such as macrophages and dendritic cells. The activation of NLRP3 inflammasome can cause cell death through caspase-1-mediated cell pyroptosis and plays an important role in the development of nervous system injury and inflammation-related diseases. This discussion aims to summarize the mechanisms of nerve damage and pain caused by excessive activation of the NLRP3 inflammasome.
