, Sept. 18 -- Scientists have found that restoring a protein in the brain can partially reverse several signs of aging in mice, while a separate treatment with the amino acid D-serine improved cognitive performance.

The findings suggest that changes in a protein called Menin, which is found in a small region of the brain, may play a role in age-related changes affecting memory, skin and bone health.

The study, led by Lige Leng of Xiamen University in China, was published in the open-access journal PLOS Biology in March 2023. It identified a possible link between brain inflammation, metabolism and aging throughout the body.

How Menin may affect aging

The researchers focused on the hypothalamus, a small region of the brain that helps re...
