Morphology of corpuscular receptors in hairy and nonhairy human skin as visualized by an antiserum to protein gene product 9.5 compared to anti-neuron-specific enolase and anti-S-100 protein.

The present study elucidates the morphology of encapsulated receptors in human skin by means of immunohistochemistry for the recently characterized neurospecific marker protein gene product 9.5, in comparison with neuronal specific enolase and S-100 protein. Only two types of corpuscles are identified, Meissner's corpuscles and simple coiled corpuscles. Moreover, this investigation reveals that though regional specialization may exist with regard to the encapsulated receptor density, the comparison of hairy and nonhairy skin does not reveal important differences.
