Pre-autonomic neurons in the hypothalamic paraventricular nucleus (PVN) project to sympathetic and parasympathetic motor nuclei in the brain stem, from where the liver and white adipose tissue (WAT) are innervated by both branches of the autonomic nervous system (ANS). Studies by our group and by others have shown that these neural pathways modulate glucose and lipid metabolism in liver and WAT. Given the abundant thyroid hormone receptor (TR) expression in the PVN we hypothes...

Introduction: Adolescents spend much time using blue-light emitting screen devices such as smartphones, tablets and computers. Blue light affects the central circadian clock in the suprachiasmatic nucleus (SCN) as well as melatonin secretion by the pineal gland. Screen use in adolescents strongly associates with reduced sleep quality and sleep duration. However, there is a lack of intervention studies that reduce blue light exposure due to screen use in adolescents.<p clas...
