We have recently described a molecular gatekeeper of the hypothalamic-pituitary-gonadal axis with observation that G protein-coupled receptor 54 (GPR54) is required in mice and men for pubertal onset pulsatile luteinizing hormone (LH) follicle-stimulating (FSH) secretion to occur. In present study, we investigate possible central mode action GPR54 kisspeptin ligand. First, show transcripts are colocalized gonadotropin-releasing (GnRH) neurons mouse hypothalamus, suggesting kisspeptin,...

Remyelination following central nervous system demyelination is essential to prevent axon degeneration. However, remyelination ultimately fails in demyelinating diseases such as multiple sclerosis. This failure of likely mediated by many factors, including changes the extracellular signalling environment. Here, we examined expression matrix molecule fibronectin on injury and how this affects oligodendrocytes progenitors. In toxin-induced lesions undergoing efficient remyelination, was...

In response to the microenvironment, microglia may polarize into either an M1 pro-inflammatory phenotype, exacerbating neurotoxicity, or M2 anti-inflammatory conferring neuroprotection. Betulinic acid (BA) is a naturally pentacyclic triterpenoid with considerable properties. Here, we aim investigate potential effects of BA on microglial phenotype polarization and reveal underlying mechanisms action. First, confirmed that promoted inhibited in lipopolysaccharide (LPS)-stimulated BV-2 cells....
