Hypothalamic Menin Decline Linked to Aging; D-Serine Supplementation Boosts Mouse Memory
Researchers led by Lige Leng at Xiamen University found that declining levels of the protein Menin in the hypothalamus drive systemic aging and cognitive loss in mice. Restoring Menin reversed age-related physical and mental decline within 30 days. Additionally, supplementing with the amino acid D-serine improved memory in three weeks, though it did not restore bone or skin health. While promising, human trials remain limited and D-serine effects vary by biological context.
