Sleep Deprivation Alters T Cell Dynamics: Melatonin as a Restorative Agent

Journal of Sleep Research, EarlyView.
ABSTRACT Sleep is an essential physiological function regulated by circadian rhythm and homeostatic regulation for emotional and physical health. Conversely, sleep deprivation (SD) is associated with weakened immune system function and overall health, which potentially leads to chronic diseases such as heart disease and diabetes.

The potential anti-cancer effects of melatonin on breast cancer

Exploration of Medicine, 2022
Melatonin is the primary hormone of the pineal gland that is secreted at night. It regulates many physiological functions, including the sleep-wake cycle, gonadal activity, free radical scavenging, immunomodulation, neuro-protection, and cancer ...

New quinoxaline derivatives as potential MT₁ and MT₂ receptor ligands. [PDF]

, 2012
Ever since the idea arose that melatonin might promote sleep and resynchronize circadian rhythms, many research groups have centered their efforts on obtaining new melatonin receptor ligands whose pharmacophores include an aliphatic chain of variable ...

Recent advances on the mechanisms regulating cholangiocyte proliferation and the significance of the neuroendocrine regulation of cholangiocyte pathophysiology [PDF]

, 2013
Cholangiocytes are epithelial cells lining the biliary epithelium. Cholangiocytes play several key roles in the modification of ductal bile and are also the target cells in chronic cholestatic liver diseases (i.e., cholangiopathies) such as PSC, PBC ...

Human Gastroenteropancreatic Expression of Melatonin and Its Receptors MT1 and MT2

PLOS ONE, 2015
The largest source of melatonin, according to animal studies, is the gastrointestinal (GI) tract but this is not yet thoroughly characterized in humans. This study aims to map the expression of melatonin and its two receptors in human GI tract and pancreas using microarray analysis and immunohistochemistry.Gene expression data from normal intestine and

Effects of Agomelatine on Sleep Across Populations: A Systematic Review and Meta‐Analysis

Journal of Sleep Research, EarlyView.
ABSTRACT Agomelatine, a melatoninergic antidepressant, is often prescribed to improve sleep disturbance, though meta‐analytic evidence is currently lacking. This systematic review and meta‐analysis assessed its efficacy and tolerability in sleep outcomes compared to placebo.

Melatonin inhibits muscular-mucosal stretch-sensitive bladder afferents via the MT2 receptors

Scientific Reports, 2022
Melatonin is a circadian rhythm regulator capable of controlling a variety of physiological processes in the body. It predominantly acts via the melatonin 1 (MT1) and MT2 receptors expressed in the CNS neurons and peripheral organs and tissues. Melatonin

Myopes have significantly higher serum melatonin concentrations than non-myopes [PDF]

, 2017
Purpose Experimental animal models of myopia demonstrate that higher melatonin (Mel) and lower dopamine (DA) concentrations actively promote axial elongation.

MT1 and MT2 melatonin receptors play opposite roles in brain cancer progression

Journal of Molecular Medicine, 2021
Primary brain tumors remain among the deadliest of all cancers. Glioma grade IV (glioblastoma), the most common and malignant type of brain cancer, is associated with a 5-year survival rate of

The role of agomelatine in appetite regulation and body weight in rats

Experimental Physiology, EarlyView.
Abstract The hypothalamic nuclei play a central role in the synthesis of anorexigenic and orexigenic neuropeptides, which are regulated by peripheral hormones, like leptin and ghrelin. Melatonergic receptors (MT1/MT2) are prominently expressed in the arcuate nucleus of the hypothalamus – an essential hub for appetite control – and in peripheral ...
