ABSTRACT
Chronic excess alcohol intake triggers the formation of enterogenic endotoxemia. TLR4 ligand localization activates nuclear transcription factor NF-κB by inducing the up-regulation of NLRP3 inflammasome and the biologically inactive IL-1ß and IL-18 precursors to form initiation of pro-inflammatory signals. Under the influence of ethanol, the damaged hepatocyte release uric acid, and adenosine triphosphate and induces NLRP3 inflammasome assembly and functional activation in Kupffer cells to promote the release of inflammatory mediators, such as interleukin-1ß and interleukin-18, that cascade mediates inflammation and drive alcoholic liver disease from steatosis to inflammation and fibrosis. The NLRP3 inflammasome acts as a ligand-sensing element and plays an important role in mediating the immune and inflammatory response in the course of alcoholic liver disease. Thus, exploring the activation mechanism of NLRP3 inflammasome and its pathogenic role may provide a new idea in the clinical treatment of alcoholic liver disease.
