Researchers have identified Menin, a brain protein in the hypothalamus, as a key regulator of aging. When Menin levels decline, it triggers inflammation, memory problems, bone loss, and other age-related changes—at least in mice. The groundbreaking finding showed that restoring Menin reversed several of these effects, while D-serine, a simple amino acid supplement, improved cognitive function. This discovery offers a promising new therapeutic avenue for combating age-related decline and age-related diseases like Alzheimer's.
