摘要: Nitric oxide (NO) is a recently discovered and highly unorthodox messenger molecule. Current evidence indicates that, in the CNS, NO produced enzymatically postsynaptic structures response to activation of excitatory amino acid receptors. It then diffuses out act on neighbouring cellular elements, probably presynaptic nerve endings astrocyte processes. In several peripheral nerves, quite possibly parts CNS as well, might be formed presynaptically thus neurotransmitter. both cases, major action activate soluble guanylate cyclase so raise cGMP levels target cells.
