(Beitrag vom Nutzer eingereicht) -------- Hypothalamic Stem Cells Regulate Aging Speed Stem cells in the brain’s hypothalamus govern how fast aging occurs in the body, scientists at Albert Einstein College of Medicine have found. The finding, made in mice, could lead to new strategies for warding off age-related diseases and extending lifespan. The hypothalamus was known to regulate important processes including growth, development, reproduction and metabolism. In a 2013 study, Einstein researchers made the surprising finding that the hypothalamus also regulates aging throughout the body. Now, the scientists have pinpointed the cells in the hypothalamus that control aging: a tiny population of adult neural stem cells, which were known to be responsible for forming new brain neurons. “Our research shows that the number of hypothalamic neural stem cells naturally declines over the life of the animal, and this decline accelerates aging. But we also found that the effects of this loss are not irreversible. By replenishing these stem cells or the molecules they produce, it’s possible to slow and even reverse various aspects of aging throughout the body,” says senior author Dongsheng Cai, M.D., Ph.D., professor of molecular pharmacology at Einstein. *** http://reliawire.com/hypothalamic-stem-cells-aging/?
