‘Vampire’ Mice May Hold Key to Eternal Youth?


‘Vampire’ Mice May Hold Key to Eternal Youth?

New studies published in Science and Nature Medicine find that older mice who are given blood from younger rodents quickly become rejuvenated, raising hopes for treating age-related degenerative conditions in humans like dementia and Alzheimer's Aging mice gain energy, while also exhibiting greater strength and memory, when injected with the blood of younger specimens, according to a new study.

Scientists at Harvard and the University of California, San Francisco, carried out experiments on rodents with ages equivalent to humans in their 20s and 60s. A protein called GDF11 — also found in human blood — is behind the rejuvenating properties, they suggest in research published in the journals Science and Nature Medicine. Concentration of the substance appears to decline in advanced years.

The findings could be used to treat age-related diseases such as dementia and Alzheimer’s. However, some have cautioned that stimulating the rapid regrowth of cells could possibly lead to increased risks of cancer.

{Interesting study. I was reading lately about the bodies "age clock" that seemingly decides when to start the aging process which eventually leads to death. Some scientist believe there is no biological reason to suggest this is an permanent condition. There may not be a classic "fountain of youth" anywhere but there may be answers in our own bodies to slow down the aging process or stop it all together. This new study seems to suggest the answer may be in our blood.... and the blood of others.

I'm not sure what we would gain from a longer life span?We would need more money before we retired and would have to put up with annoying relatives for longer. I guess we would have the choice to slow the clock down or not but I imagine it would only be a matter of time before someone decided we shouldn't have the right at all or only select groups should be allowed to prolong their lives.

Perhaps only the rich would have the right or only the Anglo-Saxon majority and minorities would be left out in the cold? The decision of whether you will live for 70 or 80 years or 110 or 130 years may have been decided before you are even born. We may end up with two very different classes of [sign in to see URL] who were born to die young and those who will watch them do it. It could be opening a very unpleasant Pandora's box. What do you think?}
