title: Presence of catecholaminergic axon-terminals containing beta-adrenergic receptor in the periventricular zone of the rat hypothalamus.
abstract: The present study, using a light microscopic double-immunofluorescence method, has revealed the presence of fibers containing both tyrosine hydroxylase- and beta-adrenergic receptor-like immunoreactivities in the rat hypothalamic periventricular zone. Subsequent immunoelectron microscopic analysis demonstrated that these belong to axon terminals. These findings suggest that presynaptic beta-adrenergic receptor is present in catecholaminergic terminals.
