Extra-lysosomal, fluoride-resistant acid phosphatase-active neuronal system subserving nociception in the rat cornea.

: Perikarya as well as central and peripheral terminals of nociceptive neurons innervating the rat cornea are genuinely labelled by an extra-lysosomal, fluoride resistant iso-enzyme of acid phosphatase. This enzyme seems to be related to the metabolism of transmitter oligopeptides characterizing such neurons.
