Quercetin is a natural polyphenolic flavonoid widely found in plants, fruits, and vegetables, has been reported to play pharmacological roles numerous pathogenic conditions. The anti-inflammatory effects of quercetin various inflammatory conditions diseases have well-documented. However, its regulatory role noncanonical inflammasome activation not yet demonstrated. This study investigated the caspase-11 inflammasome-activated responses macrophages mouse model acute lethal sepsis. protected J774A.1 from lipopolysaccharide (LPS)-induced cell death inflammasome-induced pyroptosis. It significantly decreased production mRNA expression pro-inflammatory cytokines, such as interleukin (IL)-1β, IL-18, IL-6, but tumor necrosis factor (TNF)-α, molecules, nitric oxide (NO) inducible NO synthase cells. Mechanistically, strongly suppressed autoproteolysis secretion proteolysis gasdermin D did inhibit direct binding LPS. In vivo, revealed that increased survival rate mice with sepsis serum levels cytokines without causing significant toxicity. conclusion, this highlights quercetin-mediated action through novel mechanism targets macrophages, suggesting promising agent medicine.

Benzo[a]pyrene (B[a]P), a highly carcinogenic polycyclic aromatic hydrocarbon primarily formed during incomplete organic matter combustion, undergoes series of hepatic metabolic reactions once absorbed into the body. B[a]P contributes to liver damage, ranging from molecular DNA damage onset and progression various diseases, including cancer. Specifically, induces oxidative stress via reactive oxygen species generation within cells. Consequently, more research has focused on exploring underlying mechanisms B[a]P-induced potential strategies counter its toxicity. Flavonoids, natural compounds abundant in plants renowned for their antioxidant properties, possess ability neutralize adverse effects free radicals effectively. Although extensive investigated flavonoids, limited delved regulating metabolism alleviate stress. This review aims consolidate current knowledge examines role flavonoids mitigating

Inflammasomes are intracellular multiprotein complexes that activate inflammatory signaling pathways. comprise two major classes: canonical inflammasomes, which were discovered first and activated in response to a variety of pathogen-associated molecular patterns (PAMPs) danger-associated (DAMPs), non-canonical recently only lipopolysaccharide (LPS). Although larger number studies have successfully demonstrated particularly the NLRP3 inflammasome, play roles various rheumatic diseases, including rheumatoid arthritis (RA), infectious (IR), gouty (GA), osteoarthritis (OA), systemic lupus erythematosus (SLE), psoriatic (PA), ankylosing spondylitis (AS), Sjögren’s syndrome (SjS), regulatory such as mouse caspase-11 human caspase-4 these diseases still largely unknown. Interestingly, an increasing reported possible for inflammasomes pathogenesis models disease. This review comprehensively summarizes discusses recent emerging demonstrating focusing on progression types provides new insights into strategies developing potential therapeutics prevent treat well associated by targeting inflammasomes.

Published: June 9, 2023

Inflammasomes are multiprotein complexes that activate inflammatory responses by inducing pyroptosis and secretion of pro-inflammatory cytokines. Along with many previous studies on diseases induced canonical inflammasomes, an increasing number have demonstrated non-canonical such as mouse caspase-11 human caspase-4 emerging key players in various diseases. Flavonoids natural bioactive compounds found plants, fruits, vegetables, teas pharmacological properties a wide range Many successfully flavonoids play anti-inflammatory role ameliorate inhibiting inflammasomes. Others the roles diseases, new mechanism which inhibit This review discusses recent investigated inflammasomes further provides insight into developing flavonoid-based therapeutics potential nutraceuticals against
