increase in lifespan

With age, the researchers found that the protein Ppp1r17 tends to leave the nucleus of the neurons, and when that happens, the neurons in the hypothalamus send weaker signals. With less use, the nervous system wiring throughout the white adipose tissue gradually retracts, and what was once a dense network of interconnecting nerves (left) becomes sparse (right).
