Melatonin modulates lactation by regulating prolactin secretion via tuberoinfundibular dopaminergic neurons in Hypothalamus-Pituitary system.

Melatonin modulates lactation by regulating prolactin secretion via tuberoinfundibular dopaminergic neurons in Hypothalamus-Pituitary system. Curr Protein Pept Sci. 2020 May 10;: Authors: Li H, Wei J, Ma F, Shan Q, Gao D, Jin Y, Sun P Abstract In-depth studies have identified many hormones important for controlling mammary growth and maintaining lactation. One of these is melatonin, which is synthesized and secreted by the pineal gland to regulate circadian rhythms, improve antioxidant capacity, and enhance immunity. Prolactin is secreted by the pituitary gland and is associated with growth and development of mammary glands as well as initiation and maintenance of lactation. The hypothalamus-pituitary system, the most important endocrine system in the body, regulates prolactin secretion mainly through dopamine released from tuberoinfundibular dopaminergic neurons. This review provides a reference for further study and describes regulation of lactation and prolactin secretion by melatonin, primarily via the protection and stimulation of tuberoinfundibular dopaminergic neurons.
