WebThe neurotransmitter serotonin (5-HT) plays an important role in mood disorders. It has been demonstrated that 5-HT signaling through 5-HT1A receptors (5-HT1A-R) is crucial for early postnatal hippocampal development and later-life behavior. Although this suggests that 5-HT1A-R signaling regulates early brain development, the mechanistic underpinnings of … WebWith aging, the number of stem cells declines significantly in some cases. 90,91 For example, depletion of melanocyte stem cells in the hair follicles and the appearance of mature pigmented melanocytes in the stem cell niche have been reported in both aged mice and humans, 92,93 leading to one of the most visible phenotypic changes during …
