Regulation and therapeutic potential of NLRP3 inflammasome in intestinal diseases

Abstract The NOD-like receptor family, particularly the protein 3 that contains the pyrin domain (NLRP3), is an intracellular sensing protein complex responsible for detecting patterns associated with pathogens and injuries. NLRP3 plays a crucial role in the innate immune response. Currently, a wide range of research has indicated the crucial importance of NLRP3 in various inflammatory conditions. Similarly, the NLRP3 inflammasome plays a significant role in preserving intestinal balance and impacting the advancement of diseases. In addition, several randomized trials have demonstrated the safety and efficacy of targeting NLRP3 in the treatment of colitis, colorectal cancer, and related diseases. This review explores the mechanisms of NLRP3 assembly and activation in the gut. We describe its pathological significance in intestinal diseases. Finally, we summarize current and future therapeutic approaches targeting NLRP3 for intestinal diseases.
