Fig. 8: Schematic illustration of a potential role for eNAMPT in hypothalamic circadian regulation of locomotor activity.
From: Circulating blood eNAMPT drives the circadian rhythms in locomotor activity and energy expenditure

Light and food availability control eNAMPT secretion from the liver or leukocytes to systemic circulation in a circadian manner. Blood eNAMPT acts upon the hypothalamus to drive circadian rhythms in locomotor activity via hypothalamic NAD+–SIRT–FOXO1–melanocortin pathways.
