Blood transfusions of young people will stop sickness in old age

Scientists from UCL have shown data showing that mice which were given young blood they did not develop age related diseases at the end of their lives. Geneticist at London college is sure that these experiments are real and as leading phycisians confirm they promise ventures in modern medicine.

As Dame Linda Partridge a geneticist published an analysis in journal Nature and confirmed that young blood transfusion could give a longer life to humans as well as to live free of diseases. Diseases like cancer, dementia, and heart disease untill the end of their lives.

Older mice given young blood did not develop age-related diseases and maintained sharp cognitive function, while younger ones given older blood saw the opposite effect. Professor Partridge and her co-authors Joris Deelen and P. Eline Slagboom add: ‘[B]lood is the most practically accessible and therefore the most com-monly investigated tissue, but it is much less commonly used in animal studies.

‘It will be important to develop blood-based biomarkers of risk, ageing hallmarks and responses to candidate interventions in animals.’  Researchers noted improvements in biomarkers of various major diseases, also known of indicators for certain conditions.

This included a 10 percent reduction in blood cholesterol, of which high levels are known to lead to heart disease. Other effects noted by the scientists were a 20 percent reduction in proteins called carcinoembryonic antigens.

These can be seen in high quantities in people who have various forms of cancer, the website reports, but it remains to be seen whether. The younger blood also helped to slash amyloid protein levels, which forms toxic clumps in the brains of dementia patients, by a fifth.

In particular, one 55-year-old patient with early onset Alzheimer’s began to show improvements in his condition after just one transfusion. Another, slightly older woman with more severe Alzheimer’s pathology is showing similar improvements, the start-up reported.
