Autophagy, a metabolic pathway that plays an important role in maintaining the dynamic balance of cells, has two types, i.e. non-selective autophagy and selective autophagy. The role of non-selective autophagy is primarily to allow cells to circulate nutrients in an energy-limited environment, while selective autophagy primarily cleans up the organelles inside the cells to maintain the cell structure. The NLRP3 inflammasome is an innate immune response produced by the organism that can promote the secretion of interleukin-1β and interleukin-18 through caspase-1 activation and resist the damage of some pathogens. However, when the NLRP3 inflammasome is overactivated, it can cause various inflammatory diseases, such as inflammatory liver disease and inflammatory bowel disease. Many previous studies have shown that autophagy can inhibit the NLRP3 inflammasome, while in recent years, new studies have found that autophagy can also promote the NLRP3 inflammasome in some cases, and the NLRP3 inflammasome can, in turn, affect autophagy. In this review, the interaction between autophagy and the NLRP3 inflammasome is explored, and then the application of this interaction in disease treatment is discussed.
Keywords: NOD-like receptor family pyrin domain-containing 3 (NLRP3); autophagy; inflammasome; inflammation-related disease.
