  • Title: Catecholaminergic innervation of neurons containing corticotropin-releasing factor in the paraventricular nucleus of the rat hypothalamus.
    Author: Kitazawa S, Shioda S, Nakai Y.
    Journal: Acta Anat (Basel); 1987; 129(4):337-43. PubMed ID: 3498284.
    Abstract:
    Catecholaminergic synaptic input to neurons containing corticotropin-releasing factor (CRF) in the parvocellular portion of the paraventricular nucleus (PVN) in the rat hypothalamus was observed. The experimental techniques used combine autoradiography after 3H-noradrenaline (3H-NA) injection or uptake of 5-hydroxydopamine (5-OHDA) with immunocytochemistry using CRF antiserum. CRF-like immunoreactive cell bodies and fibers in the PVN received synaptic inputs from the axon terminals in which a selective accumulation of 3H-NA or 5-OHDA was found. This finding suggests that the secretion of CRF neurons may be regulated via synapses by catecholaminergic neurons.
