BACKGROUND The aim of this study was to investigate the clinical significance of NLRP3 and HMGB1 in patients with active ulcerative colitis. MATERIAL AND METHODS This was a prospective observational study which included a total of 62 cases with active ulcerative colitis during January 2017 to December 2018. The patients were divided into a mild/moderate group or a severe group according to Sutherland Disease Activity Index (DAI) score. Clinical activity index and endoscopic index were used to determine the severity of UC. Serum levels of NLRP3, HMGB1, endothelin-1, IL-1ß, and TNF-alpha were determined by enzyme-linked immunosorbent assay (ELISA). RESULTS Sutherland DAI score, clinical activity index, and endoscopic index were all significantly higher in severe patients than in the mild/moderate group. NLRP3, HMGB1, endothelin-1, IL-1ß, and TNF-alpha were significantly higher in severe UC patients. NLRP3 level was positively correlated with HMGB1, ET-1, IL-1ß, and TNF-alpha levels. Both NLRP3 and HMGB1 were positively correlated with Sutherland DAI score, clinical activity index, and endoscopic index. CONCLUSIONS Both serum NLRP3 and HMGB1 were elevated in UC patients, and the serum levels of NLRP3 were positively correlated with serum levels of HMGB1, ET-1, IL-1ß, and TNF-alpha, as well as severity of UC patients.

Steroids, which are often used to treat the inflammation associated with various skin diseases, have several negative side effects. As extract has anti-inflammatory effects in various diseases, we evaluated the efficacy of -derived extracellular vesicles (EVEs) in decreasing 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced inflammation. We determined the effect of the EVEs on the TLR4/NF-κB/NLRP3 inflammasome in human keratinocytes and mouse ear skin.

The pathophysiologic processes of asthma are characterized not only by significant changes in miRNA expression but also by the modulation of HMGB1 and its downstream effectors. However, the specific roles of miR-15b-5p and HMGB1 in asthma remain poorly understood. This study explores the regulatory role of miR-15b-5p in asthma by targeting HMGB1.

T-2 toxin, a potent environmental pollutant, has been proved to stimulate neuroinflammation, while the connection between T-2 toxin and pyroptosis remain elusive. Dimethyl fumarate (DMF), recently identified as a neuroprotectant and pyroptosis inhibitor, has potential therapeutic applications that are underexplored. Based on present study in vitro and vivo, we demonstrated that T-2 toxin induced the activation of NLRP3-Caspase-1 inflammasome in hippocampal neurons.

This investigation explored the hepatoprotective capabilities of Bruceine A (BA) and its underlying mechanisms in mitigating hepatic fibrosis. Hepatic stellate cells (HSCs) and mouse primary hepatocytes were treated with TGF-β and subsequently exposed to BA. To assess the effects of BA on the NR2F2-HMGB1 signaling cascade, these cells underwent transfection with a siRNA vector targeting NR2F2.
