    Catecholaminergic innervation of GRF-containing neurons in the rat hypothalamus revealed by electron-microscopic cytochemistry (1989)
    Springer
    Cell & tissue research 258 (1989), S. 31-34 
    Details
    ISSN: 1432-0878

    Notes: Summary The Catecholaminergic innervation of neurons containing growth hormone-releasing factor (GRF) was examined by use of a method which combined either 5-hydroxydopamine (5-OHDA) uptake or autoradiography after intraventricular injection of 3H-noradrenaline with immunocytochemistry for GRF in the same tissue sections at the electron-microscopic level. In the ventrolateral part of the arcuate nucleus of the rat hypothalamus a large number of immunonegative axon terminals were found to make synaptic contact with GRF-like immunoreactive (GRF-LI) cell bodies and processes. 3H-noradrenaline autoradiography or 5-OHDA-labeling combined with GRF immunocytochemistry revealed that axon terminals labeled with 3H-noradrenaline or 5-OHDA make synaptic contact with the GRF-LI nerve cell bodies and processes. These findings indicate that catecholamine-containing neurons innervate GRF neurons to regulate GRF secretion via synapses in the rat arcuate nucleus.

    Distribution of immunoreactive thyrotropin-releasing hormone in the forebrain and hypophysis of the bullfrog, Rana catesbeiana (1983)
    Springer
    Cell & tissue research 233 (1983), S. 507-516 
    Details
    ISSN: 1432-0878
    Keywords: Thyrotropin releasing hormone ; Rana catesbeiana ; Hypothalamus ; Immunohistochemistry

    Topics: Biology , Medicine
    Notes: Summary The distribution of immunoreactive thyrotropin-releasing hormone (TRH) in the forebrain and hypophysis of Rana catesbeiana was studied by means of specific radioimmunoassay and immunohistochemistry based on peroxidase-antiperoxidase (PAP) techniques. A relatively high concentration of immunoassayable TRH is present in the hypothalamus. Immunoreactive TRH cell bodies are found in the anterior part of the preoptic nucleus, the dorsal infundibular nucleus, the nucleus of diagonal band of Broca, and the medial part of the amygdala. Immunoreactive nerve terminals are observed in the neurohypophysis and the external layer of the median eminence, where the terminals are in close contact with the capillary loops of the hypophyseal portal vessels. The possible role of TRH in the frog brain is discussed.

    Electron-microscopic cytochemistry of the catecholaminergic innervation of TRH neurons in the rat hypothalamus (1986)

    Notes: Summary The catecholaminergic innervation of thyrotropin-releasing hormone (TRH) neurons was examined by use of a combined method of 5-hydroxydopamine (5-OHDA) uptake or autoradiography after intraventricular injection of 3H-noradrenaline (3H-NA) and immunocytochemistry for TRH in the same tissue sections at the electron-microscopic level. TRH-like immunoreactive nerve cell bodies were distributed abundantly in the parvocellular part of the paraventricular nucleus (PVN), in the suprachiasmatic preoptic nucleus and in the dorsomedial nucleus of the rat hypothalamus. In the PVN, a large number of immunonegative axon terminals were found to make synaptic contact with TRH-like immunoreactive cell bodies and fibers. In the combined autoradiography or 5-OHDA labeling with immunocytochemistry, axon terminals labeled with 3H-NA or 5-OHDA were found to form synaptic contacts with the TRH immunoreactive nerve cell bodies and fibers. These findings suggest that catecholamine-containing neurons, probably noradrenergic, may innervate TRH neurons to regulate TRH secretion via synapses with other unknown neurons in the rat PVN.
