title: Serotonin-like immunoreactivity in rat carotid body.
abstract: Serotonin-like immunofluorescence was demonstrated in the glomus cells of the rat carotid body. Similar immunoreactivity was noted in mast cells in the organ, while no immunoreactive nerve fibers were seen. It is suggested that glomus cell serotonin could participate in the modulation of chemoreceptor activity.
