Abstract:
NO performs a wide array of cell signaling functions. Neuronal NO synthase (nNOS) immunoreactivity and nicotinamide adenine dinucleotide phosphate diaphorase (NDP) activity, a marker of nNOS, were concentrated at adult rat neuromuscular junctions and persisted in denervated muscle indicating the localization of the enzyme to the postsynaptic surface. The concentration of nNOS at the muscle endplate suggests NO could serve as a messenger pre- and postsynapticly.
