Glutamate is the main excitatory neurotransmitter in the mammalian central nervous system which at high extracellular levels leads to neuronal over-stimulation and subsequent excitotoxic neuronal cell death. Both the termination of glutamatergic neurotransmission and the prevention of neurotoxic extracellular glutamate

The receptor-coupled signal transduction systems present in isolated human choroidal melanocytes (HCOMs) were investigated. [(3)H]-inositol phosphates ([(3)H]-IPs) generated in the cells were measured by ion-exchange chromatography. cAMP generated in the cells was quantified using an enzyme immunoassay. Initially, HCOM cells

The physiological properties of endothelin-1 in ocular choroidal melanocytes are not well-known, although endothelin-1 increases the intracellular calcium concentration through endothelin-B receptors in skin melanocytes. We studied the effect of endothelin-1 on choroidal melanocytes in rabbit ocular suprachoroidal tissue. Fura-2
