Traditional Chinese medicine (TCM), with its multi-target, multi-component, and multi-pathway pharmacological properties, has emerged as a promising therapeutic drug against inflammation-driven pathologies, including AP. This review systematically discussed the assembly, activation, and pathogenic contributions of the NOD-like receptor family pyrin domain-containing 3 (NLRP3) inflammasome in AP pathogenesis. Mechanistically, NLRP3 activation exacerbated pancreatic injury through caspase-1-dependent maturation of interleukin-1β (IL-1β) and gasdermin D (GSDMD)-mediated pyroptosis, perpetuating systemic inflammation.
