...-specific vesicular transporter energized by vacuolar H + -ATPase. We found that mammalian pinealocytes, endocrine cells that synthesize and secrete melatonin, accumulate L-glutamate in their microvesicles and secrete it through exocytosis. Pinealocytes use L-glutamate as either a paracrine- or autocrine...

...F. Dubas ABSTRACT In vertebrates, L-glutamate (glutamate) is a major excitatory neurotransmitter in the brain, acting on at least three separate receptors ( Fagg, 1985 ). In insects, there is strong evidence that glutamate is the excitatory neurotransmitter at the neuromuscular synapse ( Usherwood...

... recordings from an adult locust extensor tibiae muscle fibre showing channels gated by 10 −4 moll −1 sodium L-glutamate in the absence (A) and in the presence (B) of ( + )-tubocurarine (TC). A and B are parts of continuous recordings, from separate recording sites on a muscle fibre obtained using mega-ohm...
