Nucleotide-binding oligomerization domain-like receptor family pyrin domain containing 3 inflammasome (NLRP3 inflammasome)

The NLRP3 inflammasome is a multiprotein complex within cells that acts as an innate immune sensor for diverse stress signals—including pathogens or metabolic danger—and triggers inflammatory responses. Upon activation, NLRP3 recruits partner proteins ASC and caspase-1, leading to the maturation and release of the pro-inflammatory cytokines IL-1β and IL-18, as well as inducing pyroptosis, an inflammatory type of programmed cell death[2][3][5]. These pro-inflammatory cytokines subsequently amplify immune responses and drive inflammation, which, if uncontrolled, can contribute to a range of diseases, including autoinflammatory, neurodegenerative, cardiovascular, metabolic, and infectious diseases[1][3][5][6]. Therapeutic targeting of the NLRP3 inflammasome and its downstream cytokines is a major focus in drug discovery for inflammatory pathologies.
