Webb1 sep. 2007 · Bromocriptine is a dopamine D2 receptor agonist, known to inhibit endogenous prolactin secretion from the pituitary gland. It was used to ensure that multiple handlings for injections did not result in stress-induced increases in endogenous prolactin levels and hence potentially affect phosphorylated CREB (pCREB) … Webb1 dec. 2024 · The secretion of prolactin is primarily regulated by dopamine, which is produced in the hypothalamus and inhibits prolactin secretion.

WebbProlactin is a polypeptide hormone secreted by the anterior pituitary gland under the control of dopamine neurons in the tuberoinfundibular pathway. Dopamine acting via DR2 has a direct inhibitory effect on lactotroph cells by suppressing prolactin gene expression and prolactin exocytosis. Webb16 mars 2024 · Dopamine inhibits prolactin secretion by binding to D2 receptors. Thyrotropin releasing hormone from the hypothalamus stimulates the release of prolactin. Chest wall irritation (e.g. HZV infection or surgery) can lead to hyperprolactinemia. Webb2 jan. 2024 · Drugs that enhance serotonin levels, such as selective serotonin reuptake inhibitors (SSRIs), can also increase prolactin levels. Conversely, drugs that stimulate GABA, such as benzodiazepine and sodium valproate, can reduce serum prolactin levels. oligosaccharides in human milk
