The NLRP3 inflammasome is activated by diverse stimuli, and multiple molecular and cellular events, including ionic flux, mitochondrial dysfunction, and the production of reactive oxygen species, and lysosomal damage have been shown to trigger its activation. In this review, we summarize our current understanding of the mechanisms of NLRP3 inflammasome activation by multiple signaling events, and its regulation by post-translational modifications and interacting partners of NLRP3. The innate immune system is the first line of host defense and the engagement of germline-encoded pattern-recognition receptors PRRs activate it in response to harmful stimuli, such as invading pathogens, dead cells, or environmental irritants [ 1 ]. PRRs recognize the presence of unique microbial components, called pathogen-associated molecular patterns PAMPs or damage-associated molecular patterns DAMPs , which are generated by endogenous stress, and trigger downstream inflammatory pathways to eliminate microbial infection and repair damaged tissues.

Cryopyrin is found mainly in white blood cells and in cartilage-forming cells chondrocytes. NLR proteins are involved in the immune system, helping to start and regulate the immune system's response to injury, toxins, or foreign invaders. NLR proteins recognize specific molecules and respond by helping to turn on activate certain parts of the immune system. Cryopyrin recognizes bacteria; chemicals such as asbestos, silica, and uric acid crystals; and compounds released by injured cells. Cryopyrin molecules assemble themselves, along with other proteins, into structures called inflammasomes, which help trigger the process of inflammation. Inflammation occurs when the immune system sends signaling molecules as well as white blood cells to a site of injury or disease to fight foreign invaders and help repair damaged tissues. Once the threat is over, the body stops inhibits the inflammatory response, to prevent damage to its own cells and tissues. CAPS are a group of conditions that have overlapping signs and symptoms.

It has been found that a variety of stimuli including danger-associated molecular patterns DAMPs, such as silica and uric acid crystals and pathogen-associated molecular patterns PAMPs can activate NLRP3 inflammasome, but the specific regulatory mechanisms of NLRP3 inflammasome activation remain unclear.

NLRP3 NOD-, LRR- and pyrin domain-containing protein 3 is an intracellular sensor that detects a broad range of microbial motifs, endogenous danger signals and environmental irritants, resulting in the formation and activation of the NLRP3 inflammasome. Recent studies have revealed new regulators of the NLRP3 inflammasome, including new interacting or regulatory proteins, metabolic pathways and a regulatory mitochondrial hub. In this Review, we present the molecular, cell biological and biochemical bases of NLRP3 activation and regulation and describe how this mechanistic understanding is leading to potential therapeutics that target the NLRP3 inflammasome.

The NLRP3 inflammasome is a multiprotein complex that plays a pivotal role in regulating the innate immune system and inflammatory signaling. NLRP3 is the most extensively studied inflammasome to date due to its array of activators and aberrant activation in several inflammatory diseases. Studies using small molecules and biologics targeting the NLRP3 inflammasome pathway have shown positive outcomes in treating various disease pathologies by blocking chronic inflammation. In this review, we discuss the recent advances in understanding the NLRP3 mechanism, its role in disease pathology, and provide a broad review of therapeutics discovered to target the NLRP3 pathway and their challenges.
