Scientists find the brain region that controls ageing. Is it True?
"Is this the key to eternal youth?"
For generations, we have tried, and failed, to find the key to eternal youth.
But scientists think they may now be one step closer to unlocking the secret.
New research has found that a single region of the brain may control the ageing process.
Researchers believe that the hypothalamus – the area of the brain which controls hunger, thirst, body temperature and fatigue - may be the ‘fountain of ageing’, controlling how the body declines over time.
They say they have discovered a specific age-related signalling pathway which opens up new strategies for combating diseases of old age and extending lifespan.
Senior author Professor Dongsheng Cai, at Albert Einstein College of Medicine in the United States, said: ‘Scientists have long wondered whether ageing occurs independently in the body's various tissues or if it could be actively regulated by an organ in the body.
‘It's clear from our study that many aspects of ageing are controlled by the hypothalamus.
‘What's exciting is that it's possible - at least in mice - to alter signalling within the hypothalamus to slow down the ageing process and increase longevity.’
The hypothalamus, located deep within the brain, is known to play fundamental roles in growth, development, reproduction and metabolism.
