In monoaminergic cells, the neurotransmitter is accumulated into secretory or synaptic vesicles by a tetrabenazine- and reserpine-sensitive transporter, catalyzing an H+/monoamine antiport. The major vesicular monoamine transporter from bovine chromaffin cells was cloned, using sequences common to adrenal medulla and brain rat vesicular monoamine(More)
BACKGROUND Nanomaterials are widely used in industry for their specific properties. Silver nanoparticles (Ag NPs) are largely used in several consumer products notably for their antibacterial properties and will likely be found in wastewater, then in the receiving environment. The development of a product capable to sequestrate those released contaminants(More)
Guidance molecules regulate the navigation of retinal ganglion cell (RGC) projections toward targets in the visual thalamus. In this study, we demonstrate that the G-protein-coupled receptor 55 (GPR55) is expressed in the retina during development, and regulates growth cone (GC) morphology and axon growth. In vitro, neurons obtained from gpr55 knockout(More)
BACKGROUND Engineered nanoparticles have unique properties compared to bulk materials and their commercial uses growing rapidly. They represent a potential risk for environment and health and could be eventually released in water. Silver nanoparticles (Ag NP) are applied in various products and are well-known for their antibacterial properties. Nowadays,(More)
The process of muscular atrophy following denervation has been tentatively ascribed to the influence of glucocorticoids (G) because of the rapid increase of cytosolic G receptors (RG) after sciatic nerve section. It appears however that the level of muscular atrophy is similar: in slow or fast-twitch muscles in spite of huge variations in RG; in intact or(More)
