[NADPH-diaphorase localization in the radial nerve cords of the starfish Patiria pectinifera].
The presence and localization of NADPH-diaphorase (NADPH-d) in the radial nerve cords of Patiria pectonifera was shown by electron histochemistry. NADPH-d-positive structures were found in ectoneural and hyponeural regions of the radial nerve cord. Ultrastructural localization of NADPH-d was detected in neurons, sensory cells, supporting cells, and in the nerve plexus. The highest enzymatic activity in ectoneural region of the radial nerve cord is due, presumably, to the involvement of NADPH in sensory signal processing.
