Functional interplay between non-canonical inflammasomes and autophagy in inflammatory responses and diseases

The inflammasome is a cytosolic multiprotein platform that plays a key role in the inflammatory response, an essential innate immune response that protects the body from pathogens and cellular danger signals. Autophagy is a fundamental cellular mechanism that maintains homeostasis through the elimination and recycling of dysfunctional molecules and subcellular elements. Many previous studies have demonstrated a functional interplay between canonical inflammasomes that were earlier discovered and autophagy in inflammatory responses and diseases. Given the increasing evidence that non-canonical inflammasomes are unique and key factors in inflammatory responses, the functional interplay between non-canonical inflammasomes and autophagy is noteworthy. Recent studies have demonstrated that non-canonical inflammasomes and autophagy are functionally correlated with inflammatory responses and diseases. This review comprehensively discusses recent studies that have investigated the functional interplay of non-canonical inflammasomes, such as mouse caspase-11 and human caspase-4, with autophagy and autophagy-related proteins in inflammatory responses and diseases and provides insight into the development of novel anti-inflammatory therapeutics by modulating the functional interplay between non-canonical inflammasomes and autophagy.
