"Menin protein holds key to reversing aging, new study suggests"
A new study in mice has identified a previously unknown trigger of aging in the brain's hypothalamus, involving the age-related reduction of a protein called menin. The study suggests that a reduction in menin in the hypothalamus results in neuroinflammation that may cause characteristics of aging. The authors of the study also determined that a loss of menin causes a reduction in levels of an enzyme required for the production of the neurotransmitter, the amino acid D-serine. The study proposes that supplements of menin and D-serine may be able to reverse aspects of aging in humans.
