OBJECTIVE: Chronic inflammation has been recognized as having a prominent role pathogenesis of benign prostatic hyperplasia (BPH) and cancer. It is believed that chronic inflammation induces prostatic fibromuscular growth. This correlation has been clearly illustrated by both in vivo and in vitro studies; however, current experimental models of BPH require complex surgery or hormonal treatment. Therefore, the aim of the present study was to propose a new murine model of BPH/prostatitis induced by intraurethral injection of LPS...

Epidemiological studies have shown that inflammation plays a critical role in the development and progression of various chronic diseases, including cancers, neurological diseases, hepatic fibrosis, diabetic retinopathy, and vascular diseases. Decursin and decursinol angelate (DA) are pyranocoumarin compounds obtained from the roots of Angelica gigas. Several studies have described the anti-inflammatory effects of decursin and DA. Decursin and DA have shown potential anti-inflammatory activity by modulating growth factors such as vascular endothelial growth factor, transcription factors such as signal transducer and activator of transcription 3 and nuclear factor kappa-light-chain-enhancer of activated B cells, cellular enzymes including matrix metalloproteinases cyclooxygenase, and protein kinases such as extracellular receptor kinase, phosphatidylinositol-3-kinase, and protein kinase C...

INTRODUCTION: Graves' orbitopathy (GO) is an autoimmune inflammatory disorder affecting the orbit around the eye. Astragaloside IV (AS-VI) is the main active ingredient of the Chinese herbal medicine Huangqi (Radix Astragali Mongolici). AS-IV exhibits antioxidant and anti-inflammatory properties, and shows therapeutic potential in a number of ischemic and inflammatory diseases; however, its pharmaceutical activities in GO remain undefined. MATERIALS AND METHODS: In this study, we investigated the effects of AS-IV on interleukin (IL)-1β-induced orbital fibroblast inflammation in vitro and GO orbital inflammation and ocular histopathological changes in vivo, as well as the underlying mechanisms responsible for these effects...

The inflammatory response expressed after wound healing would be the recapitulation of systemic extra-embryonic functions, which would focus on the interstitium of the injured tissue. In the injured tissue, mast cells, provided for a great functional heterogeneity, could play the leading role in the re-expression of extra-embryonic functions, i.e., coelomic-amniotic and trophoblastic-vitelline. Moreover, mast cells would favor the production of a gastrulation-like process, which in certain tissues and organs would induce the regeneration of the injured tissue...

The aim of this study was to understand whether insulin-like growth factor-binding protein-6 (IGFBP-6) has functional effects on neutrophils, in particular when they cross epithelium during inflammation. We found that IGFBP-6 increased ROS production (cytofluorimetry), degranulation of primary and tertiary granules (ELISA) and transmigration through the epithelial monolayer. No priming by IGFBP-6 on neutrophils stimulated by either PMA or fMLP was observed. IGFBP-6 is an agonist of neutrophils' functions, most likely when these cells have been already activated by other stimuli...

OBJECTIVE: Glucagon-like peptide-1 (GLP-1)-based therapy via G protein-coupled receptor (GPCR) GLP-1R, to attenuate hyperglycemia in critical care has attracted great attention. However, the exaggerated inflammation by GLP-1R agonist, Exendin-4, in a mouse model of burn injury was quite unexpected. Recent studies found that GPCR might elicit proinflammatory effects by switching from Gαs to Gαi signaling in the immune system. Thus, we aimed to investigate the possible Gαs to Gαi switch in GLP-1R signaling in monocyte following burn injury...

Protein Kinase C (PKC) regulates the release of pro-inflammatory compounds from IgE/antigen-activated mast cells by unknown mechanisms. In this study, we show for the first time that PKC inhibitor Ro-03-0432, which inhibits RBL-2H3 exocytosis/degranulation in a concentration-dependent fashion, prevents the phosphorylation of membrane fusion factor Munc18a at Ser 313. Our study provides fresh evidence that PKC-dependent protein phosphorylation may contribute to the intricate regulation of mast cell degranulation by directly targeting the fusion factors...
