Uncoupling protein-2 regulates M1 macrophage infiltration of gingiva with periodontitis

Uncoupling Protein 2 Negatively Regulates

Uncoupling protein-2 regulates lifespan in mice.

The long-term effects of uncoupled mitochondrial respiration by uncoupling protein-2 (UCP2) in mammalian physiology remain controversial. Here we show that increased mitochondrial uncoupling activity of different tissues predicts longer lifespan of rats compared with mice. UCP2 reduces reactive oxygen species (ROS) production and oxidative stress throughout the aging process in different tissue...

Uncoupling Protein 2 Regulates Palmitic Acid-Induced Hepatoma Cell Autophagy

Mitochondrial uncoupling protein 2 (UCP2) is suggested to have a role in the development of nonalcoholic steatohepatitis (NASH). However, the mechanism remains unclear. Autophagy is an important mediator of many pathological responses. This study aims to investigate the relationship between UCP2 and hepatoma cells autophagy in palmitic acid- (PA-) induced lipotoxicity. H4IIE cells were treated ...

Simvastatin regulates CXC chemokine formation in streptococcal M1 protein-induced neutrophil infiltration in the lung.

Streptococcus pyogenes of the M1 serotype can cause streptococcal toxic shock syndrome and acute lung injury. Statins exert beneficial effects in septic patients although the mechanisms remain elusive. This study examined effects of simvastatin on M1 protein-provoked pulmonary inflammation and tissue injury. Male C57BL/6 mice were pretreated with simvastatin or a CXCR2 antagonist before M1 prot...

Anti-inflammatory Effects of PMX205 in Mouse Macrophage Periodontitis Model

Background: C5areceptor antagonistPMX205 is a synthetic hexapeptidecapable of blocking C5a-C5a receptor (C5aR) axis by simulating C5a active C-terminal amino acid residues. This hexapeptide presents good anti-inflammatory effects in a myriad inflammation models. The anti-inflammatory effect of PMX205 on periodontitis is yet to be fully fathomed. Objective: To examine the anti-inflammatory effec...
