The critical intracellular pattern recognition receptor NLRP3 senses pathogenic organisms and endogenous danger signals via forming inflammasomes to orchestrate innate immune responses. Dysfunction of NLRP3 inflammasomes is implicated in several inflammatory disorders. Hence, it is important to uncover the mechanisms preventing sustained NLRP3 inflammasome activation. Recently, we revealed that ZDHHC12-mediated palmitoylation enhances NLRP3 degradation through the chaperone-mediated autophagy pathway, and identified gain-of-function variants of NLRP3 in autoinflammatory diseases, which induce excessive NLRP3 inflammasome activation through decreased NLRP3 palmitoylation level and impaired chaperone-mediated autophagic degradation of NLRP3.

Cigarette smoke (CS), an indoor environmental pollution, is an environmental risk factor for diverse neurological disorders. However, the neurotoxicological effects and mechanisms of CS on Alzheimer's disease (AD) progression remain unclear. We found that CS accelerated the progression of AD, including increasing β-amyloid (Aβ) plaque deposition and exacerbating cognitive decline.

Mushroom poisoning, predominantly caused by α-amanitin, is a critical food safety concern in worldwide, with severe cases leading to hepatotoxicity and fatalities. This study delves into the hepatotoxic effects of α-amanitin, focusing on the NLRP3 inflammasome and PPAR-γ's regulatory role in inflammation. In vitro studies with L-02 cells showed that α-amanitin reduces cell viability and triggers NLRP3 inflammasome activation, increasing NF-κB phosphorylation and pro-inflammatory cytokines IL-18 and IL-1β.
