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.

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. In this review, we summarize current understanding of the regulatory mechanisms of NLRP3 inflammasome activation as well as inhibitors that specifically and directly target NLRP3. The NLRP3 inflammasome can trigger inflammation by sensing a wide range of stimuli, but the specific mechanisms are still unclear. The innate immunity is the first line of defense that recognizes infection and initiates the process of pathogen clearance and tissue repair. One of the most important complexes which participates in these processes is the inflammasome, first described by Martinon in 1. Upon activation, the inflammasome also promotes an inflammatory form of cell death named pyroptosis, which is regulated by the N-terminal domain of gasdermin D GSDMD by forming pores in the plasma membrane 2 , 3 , 4. Among these inflammasomes, the NLRP3 inflammasome is the most extensively studied. Activation of NLRP3 inflammasome in macrophages requires two steps: priming and activation. Moreover, the post-translational modifications PTMs of NLRP3 during the priming step, such as phosphorylation and ubiquitination which we will discuss later, have been suggested to play critical roles in NLRP3 inflammasome activation.

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 ].

Metrics details. This review first explains the activation and regulatory mechanism of the NLRP3 inflammasome. Secondly, we focus on the role of the NLRP3 inflammasome in various inflammation-related diseases. Finally, we look forward to new methods for targeting the NLRP3 inflammasome to treat inflammation-related diseases, and provide new ideas for clinical treatment. The innate immune system acts as the first line of host defense to trigger the adaptive immune response. This system initiates downstream inflammatory cascades in response to noxious stimuli through germline-encoded pattern recognition receptors PRRs.

The authors concluded that their data demonstrated the role of DDX3X in driving NLRP3 inflammasome and stress granule assembly, and suggested a rheostat-like mechanistic paradigm for regulating live-or-die cell fate decisions under stress conditions. Considering its safety and specific effect on NLRP3 inflammasome, this study provides a potentially practical pharmacological avenue for treating NLRP3 inflammasome-related diseases.
