Immunocytochemical study on the localization of neuron-specific enolase and S-100 protein in the carotid body of rats.
Light- and electron-immunocytochemical investigation with the peroxidase-antiperoxidase (PAP) procedure revealed neuron-specific enolase and S-100 protein-like immunoreactivities specifically localized in the chief cells and the sustentacular cells of the rat carotid body, respectively. This finding suggests a neuron-like nature of the chief cells and a glia-like nature of the sustentacular cells on both embryological and functional bases.
