Abstract:

Gouty arthritis is a type of monosodium urate (MSU) crystals-induced inflammation in the articular tissue and shows the increased levels of neutrophil infiltration and interleukin-1β (IL-1β) secretion. MSU is capable of activating IL-1β through a nucleotide-binding oligomerization domain-like receptor containing pyrin domain 3 (NLRP3) inflammasome. Epigallocatechin gallate (EGCG), a bioactive polyphenol in green tea with potent antioxidant activity, is effective to preventrheumatoid arthritis and osteoarthritis. However, it remains unclear whether EGCG improves gouty inflammation. This study aimed to investigate the effect of EGCG on MSU-induced inflammation and NLRP3 inflammasome activation. C57BL/6 mice were received subcutaneous injection or oral gavage of EGCG before the intraperitoneal injection of MSU. The results demonstrated that EGCG inhibited MSU-induced neutrophil infiltration and IL-1β secretion. Furthermore, EGCG decreased MSU-triggered neutrophil cytosolic factor 1 (NCF-1) and NLRP3 protein expression, limiting pro-inflammatory mediator secretionsuch as IL-1β, IL-6, monocyte chemoattractant protein-1 (MCP-1) and serum amyloid A (SAA). In addition, EGCG treatment suppressed NLRP3 inflammasome activation in MSU-challenged THP-1 monocytes. These findings indicate that EGCG treatment ameliorates MSU-induced inflammation, suggesting that EGCGexerts anti-inflammatory effect against MSU-induced acute gout attack.
