Western blotting confirmed that these signals were primarily produced by soluble Nrg1 derived from a 45-kDa Nrg1 precursor mainly identified in the hypothalamus...

Chowdrey We have examined the effects of adrenalectomy (ADX) on neuropeptide Y (NPY) content in the posterior pituitary of the rat. In rats given 2% saline to drink for 12 days, plasma osmolality increased to 343...

Intracerebroventricular infusion of HA (34-540 nmol) increased the plasma levels of ACTH and β-END immunoreactivity (β-ENDir) in a dose-dependent manner. Pretreatment with antiserum to CRH or AVP prevented the ACTH response to 270 nmol HA...

...Paul A. Garris; Nira Ben-Jonathan Dopamine (DA) from both the posterior pituitary (PP) and stalk-median eminence (SME) inhibits prolactin (PRL) secretion from the anterior pituitary. Estradiol participates in the regulation of PRL release, in part by modulating DA release from the SME. However...

...Paul A. Garris; Nira Ben-Jonathan Opioid peptides are present in both the posterior pituitary (PP) and stalk-median eminence (SME). Their effects on the dopaminergic neurons in the SME are well documented, but little is known concerning their role in the regulation of dopamine (DA) release from...

...Kiyoshi Tanaka; Masami Murakami; Monte A. Greer We have found thyroxine 5’-deiodinase in rat posterior pituitary. The isozyme pattern was different in intermediate and neural lobes. The former contained only type I enzyme. In the neural lobe, in euthyroidism only type I was found while...

Cell bodies containing galanin-like immunoreactivity were localized in the supraoptic, magnocellular paraventricular and accessory magnocellular neurons with axons traversing the internal layer and terminating in the posterior pituitary.

...Moshe Laudon; James F. Hyde; Nira Ben-Jonathan Plasma PRL levels in male rats are highest during the peripubertal period. We previously reported that the posterior pituitary (PP) contains a potent PRL-releasing factor (PRF), a trypsin-insensitive small peptide which is distinct from known PRL...

...Michael R. Dashwood; Iain C.A.F. Robinson Specific binding sites for vasopressin (AVP) were compared in the kidney and posterior pituitary gland from normal and homozygous Brattleboro rats using autoradiography with [ 3 H]-AVP. The specificity of ligand binding was assessed by displacement with AVP...

...James F. Hyde; Ichiro Murai; Nira Ben-Jonathan We have recently shown that the posterior pituitary (neurointermediate lobe) contains a potent prolactin (PRL)-releasing factor (PRF) which is distinct from known PRL secretagogues. Posterior pituitary PRF appears to be a small peptide of an unknown...
