Prolactin at moderately increased levels confers a neuroprotective effect in non-secreting pituitary macroadenomas.

PLoS ONE, 2022
ContextProlactin, a hormone synthesized by the anterior pituitary gland demonstrates promise as a neuroprotective agent, however, its role in humans and in vivo during injury is not fully understood.ObjectiveTo investigate whether elevated levels of ...

Utility of Cannulated Prolactin to Exclude Stress Hyperprolactinemia in Patients with Persistent Mild Hyperprolactinemia

Clinical Medicine Insights: Endocrinology and Diabetes, 2021
Background: Stress-induced hyperprolactinemia can be difficult to differentiate from true hyperprolactinema and may result in patients having unnecessary investigations and imaging.

Gender-specific reference intervals for serum prolactin concentrations before and after precipitation by polyethylene glycol

Proceedings of Singapore Healthcare, 2022
Prolactin, a hormone secreted by the anterior pituitary, exists in three major forms in circulation. The macroprolactin form is biologically inactive but contributes to elevated serum prolactin concentrations.

Abnormal prolactin secretion is associated with changes in metabolic health biomarkers in acyclic female African elephants (Loxodonta africana)

Theriogenology Wild, 2023
Circulating prolactin aberrations (chronically high or low concentrations) have been shown to have strong associations with ovarian dysfunction in African female elephants.

Metode pembuatan antiprolaktin pada hewan coba kambing lokal sebagai penghambat proses rontok bulu pada ayam arab petelur

Journal of Biological Researches, 2012
Anti-prolactin has a specific activity against prolactin. It neutralizes prolactin action in circulation. The effect of such neutralization is the inhibition of feather fall off process, so that hens may be able to produce eggs again. Anti-prolactin can

Prolactin and vitiligo: proposed autocrine/paracrine actions

Journal of the Egyptian Women’s Dermatologic Society, 2021
Background The exact cause of vitiligo remains unclear. Several theories have been proposed, including autoimmune and neuroendocrine theories. Prolactin has been studied as an immunomodulatory factor in several autoimmune diseases.

Elevated Prolactin during Pregnancy Drives a Phenotypic Switch in Mouse Hypothalamic Dopaminergic Neurons

Cell Reports, 2019
Summary: Altered physiological states require neuronal adaptation. In late pregnancy and lactation, a sub-population of the mouse hypothalamic tuberoinfundibular dopaminergic (TIDA) neurons alters their behavior to synthesize and release met-enkephalin ...

Factors associated with the level of prolactin in patients under remission from Alcohol Use Disorder: A gender perspective

Neuropsychopharmacology Reports, 2021
Background Prolactin mirrors the dopaminergic activity in the brain which is key to understanding alcohol use disorders (AUD). Still, patients with AUD are a heterogenous group and there seem to be gender differences in the relationship between alcohol ...
