Suprachiasmatic nucleus vasopressin

Revermann M, Maronde E, Ruth P, Korf HW (2002) Protein kinase G I immunoreaction is colocalized with arginine-vasopressin immunoreaction in the rat suprachiasmatic nucleus. Neurosci Lett 334 119-22... [Pg.558]

In the single electron microscopic immunocytochemical study thus far carried out with these antibodies (242), 5-HT7 receptors were described as located in neuronal somata and dendrites, fine unmyelinated axons, and axon terminals of the mouse suprachiasmatic nucleus (SCN). After double immunoperoxidase (5-HT7) and immunogold labeling, some of these SCN soma-dendrites and axon terminals could be shown to be GABA, vasoactive intestical polypeptide (VIP), or vasopressin (VP) immunoreactive. Astrocytes in the SCN, characterized by their numerous filaments, were also reported as immunopositive for 5-HT7 receptors. [Pg.299]

The mammalian suprachiasmatic nuclei contain an endogenous pacemaker that generates daily rhythms in behaviour and secretion of hormones. They stimulate evening ACTH secretion in the rat (Cascio etal. 1987). Kalsbeek etal. (1996) used microdialysis-mediated intracerebral administration of the vasopressin V,-receptor antagonist to study the mechanisms underlying the circadian control of basic corticosterone release in the rat. By timed administration of the vasopressin antagonist divided equally over the day/night cycle, they were able to uncover the existence of an additional stimulatory input from the suprachiasmatic nucleus to the hypothalamo-pituitary-adrenal axis. [Pg.525]
