How does transfusion of young blood affect older people?
Is it possible that transmission of blood from young people to old people can revitalize poor health? Researchers have already managed to do this, but for the time being only in mice. Are the results transferable to people?
Can we improve our health in the future by transferring blood from young people to older people? The scientists at University College London dealt with this topic and published the results of their analysis in the English-language journal "Nature".
Results have to be transferred to humans
Such blood transmission could become a tool for improving health in old age in the future, explains study author Professor Linda Partridge from the UCL Institute of Healthy Aging. Her work is part of research on optimized treatment of the elderly and how to better address the global challenge of aging. As people get older, the likelihood of many health problems and illnesses increases. Doctors have long been trying to understand whether and how aging can be influenced. The results obtained on mice are promising, but have yet to be checked in humans. Research done in this area has already shown that transferring blood from a young mouse to a sick older mouse can help maintain vitality.
Blood infusions can affect cognitive and neurological impairments
In 2014, researchers from Stanford University, led by neuroscientist Tony Wyss-Coray, found that blood infusions in young mice affect cognitive and neurological impairments in older mice. The first clinical applications are already running. The US study called Ambrosia offers older subjects transfusion of young blood. 2.5 liters of blood cost about $ 8,000. Another $ 5.5 million was invested in another program called Elvian.
Blood protein GDFII could be the key
The analysis looks at how people can also benefit from blood transfusions. In particular, research is now focusing on the question of whether a blood protein called GDFII could be the key to improving health through blood transmission.
Can young gut bacteria improve the microbiome of older people?
While it is too early to say whether the blood exchange offerings could benefit the patient, Professor Partridge says that other forms of intervention are needed to treat typical diseases of aging that are currently at high cost for healthcare providers to lead. Not only the blood of older people can be used to maintain health. The professor points out that the bacteria that are removed from the intestines of a young person could also improve poorly functioning microbiomes in older people. (as)
