Tiny brain part may hold anti-ageing key
The hypothalamus, a small bundle of neurons at the base of the brain, governs how quickly the body ages.
Tests on laboratory mice pinpointed ageing control to a tiny population of adult stem cells within the brain region.
Lead investigator Professor Dongsheng Cai, of Albert Einstein College of Medicine in New York City, said: “Our research shows that the number of hypothalamic neural stem cells naturally declines over the life of the animal and this decline accelerates ageing.
“But we also found that the effects of this loss are not irreversib…
