Enkephalins and Pituitary Hormone Release Modification of Responsiveness to LHRH

Hormone Research, 2008
An intraperitoneal injection of leucine-enkephalin into rats stimulates gonadotropin and prolactin release. To elucidate the mechanism of this releasing property of leucine-enkephalin, rat hemipituitaries were incubated with either enkephalin alone or enkephalin in combination with LHRH.

The role of immunopeptides in the regulation of anterior pituitary hormone release

Trends in Endocrinology & Metabolism, 1990
The anterior pituitary lobe secretes hormones that regulate the functioning of the immune system which, in turn, produces thymic hormones and interleukin proteins capable of altering neuroendocrine responsiveness. Interleukin-1 is released during inflammation and activates the hypothalamic-pituitary-adrenal axis, which subsequently diminishes the ...

Effects of Thymosin Alpha-1 on Pituitary Hormone Release

Neuroendocrinology, 2008
The thymosins are a family of hormone-like products of epithelial cells of the thymus which are important in maintenance and function of the immune system. Thymosin fraction 5, a partially purified extract of calf thymus, can influence pituitary hormone release.

Potentiation of Luteinizing Hormone Release by Estradiol at the Level of the Pituitary

Neuroendocrinology, 2008
The objective of this study was to determine the influence of estradiol-17β and/or progesterone on gonadotropin secretion at the level of the pituitary. Female rats in which the hypothalamo-hypophyseal connections had been permanently interrupted after castration served as the experimental model in which the effect of estradiol and/or progesterone on ...

Hypothalamic action of cachectin to alter pituitary hormone release

Brain Research Bulletin, 1989
Cachectin (tumor necrosis factor, TNF) is a macrophage hormone which is released during infection and after injection of bacterial lipopolysaccharides. We have already demonstrated that the peptide has direct action on the pituitary to alter pituitary hormone release in vitro. To evaluate its action in vivo, we injected it into the third ventricle (3V)

A Receptor in Pituitary and Hypothalamus That Functions in Growth Hormone Release

Science, 1996
Small synthetic molecules termed growth hormone secretagogues (GHSs) act on the pituitary gland and the hypothalamus to stimulate and amplify pulsatile growth hormone (GH) release. A heterotrimeric GTP-binding protein (G protein)-coupled receptor (GPC-R) of the pituitary and arcuate ventro-medial and infundibular hypothalamus of swine and humans was ...

Effect of exogenous glucagon on pituitary polypeptide hormone release

Metabolism, 1970
Abstract Anterior pituitary hormone secretion following administration of crystalline glucagon was studied in three phases, i.e., after subcutaneous injection, after intravenous injection, and after intravenous injection during constant glucose infusion.

Galanin modulates pituitary hormones release.

Neuro endocrinology letters, 2006
Galanin and its receptors are widely distributed within the central and peripheral nervous system, especially in hypothalamus including preoptic area, paraventricular nucleus (PVN), supraoptic nucleus (SON) and median eminence. Galanin plays an important role in the control of food intake, energy expenditure, reproduction, water balance and various ...

Role of Monokines in Control of Anterior Pituitary Hormone Release

1990
It has long been known that endogenous pyrogen, released as a result of injection of typhoid vaccine or in response to infection, produces fever and increases ACTH secretion. Recent studies have indicated that endogenous pyrogen is, at least in part, IL-1. This monokine has now been shown to activate the release of ACTH by a hypothalamic mechanism with

Stimulation of luteinising hormone release by luteinising hormone-releasing hormone in the porcine anterior pituitary: The role of cyclic AMP

Molecular and Cellular Endocrinology, 1978
Abstract Cells dissociated from porcine pituitary glands have been used to examine the relationship between cyclic AMP levels and the stimulation of luteinising hormone (LH) secretion by luteinising hormone-releasing hormone (LHRH). It has been shown that while dibutyryl cyclic AMP and theophylline have a modest and, under some conditions, an ...
