HA, besides its function in immune processes, is probably a neurotransmitter in mammalian brain. It is synthesized by a specific decarboxylase localized in the cytoplasm of nerve endings. It is stored in synaptic vesicles. Its release might depend on nerve-impulse flow; specific receptors to this amine have been evidenced both electrophysiologically and by(More)
Acetylcholinesterase activity was detected in the carotid labyrinth of amphibians by both biochemical and histochemical methods. The histochemical tests showed enzyme activity in surfaces of afferent and efferent nerve terminals in contact with type I cells, but none within the type I cells. Acetylcholinesterase activity occurred on some, though not all,(More)
