Nitric oxide inhibits lipopolysaccharide-induced inducible nitric oxide synthase expression and its own production through the cGMP signaling pathway in murine microglia BV-2 cells.
The present study examined the effect of the nitric oxide (NO) donor NOC18 on lipopolysaccharide (LPS)-induced NO production to investigate a regulation mechanism of NO production by microglial cells. LPS increased the levels of NO and inducible NO synthase (iNOS) protein in BV-2 murine microglial cells in a concentration-dependent manner. Pretreatment with NOC18 for 24 h concentration-dependen...
متن کاملConstituents of Limonia acidissima inhibit LPS-induced nitric oxide production in BV-2 microglia.
The ethyl acetate (EtOAc) soluble fraction of the 85% ethanol (EtOH) extract of the dried bark of Limonia acidissima potently inhibited nitric oxide (NO) production in lipopolysaccharide (LPS) activated BV-2 cells, a microglial cell line. Bioassay-guided column chromatography separation afforded a new stereoisomer of neolignan, (7'E)-(7R,8S)-4-hydroxy-3,5'-dimethoxy-4',7-epoxy-8,3'-neolig-7'-en...
متن کاملInhibitory constituents of lipopolysaccharide-induced nitric oxide production in BV2 microglia isolated from Amomum tsao-ko.
A methanolic extract of the fruits of AMOMUM TSAO-KO (Zingiberaceae) significantly attenuated nitric oxide production in lipopolysaccharide-simulated BV2 microglia. Two new bicyclic nonanes characterized as 6,7-dihydroxy-indan-4-carbaldehyde ( 1) and 6-hydroxy-indan-4-carbaldehyde ( 2) were isolated with the eleven known compounds 6,7-dihydroxy-3,7-dimethyloct-2-enoic acid ( 3), tsaokoin ( 4), ...
متن کاملRecognition of Betaine as an Inhibitor of Lipopolysaccharide-Induced Nitric Oxide Production in Activated Microglial Cells
Background: Neuroinflammation, as a major outcome of microglia activation, is an important factor for progression of neurodegenerative disorders including Alzheimer's disease and Parkinson's disease. Microglial cells, as the first-line defense in the central nervous system, act as a source of neurotoxic factors such as nitric oxide (NO), a free radical which is involved in neuronal cell death. ...
متن کاملInhibition of Lipopolysaccharide-Induced Neuroinflammatory Events in Bv-2 Microglia by Chestnut Peel Extract
Purpose: To evaluate the protective effects of chestnut (Castenea cranata Siebold & Zucc., Fagaceae) peel extract on stimulated BV-2 microglial cells as well as its anti-oxidant properties. Methods: The ethyl acetate fraction of C.cranata peel (CCP) extract was used in the study to evaluate the anti-neuroinflammatory effects in BV-2 microglial cells. Cell viability was performed by 3-(4, 5dimet...
