Scientists say that young blood transfusions can end the disease in the elderly

It seems that Dracula was on something when he drank the blood of young girls.

Many start-ups have tinkered with blood transfusions of young adults to treat age-related diseases.

But a major geneticist from University College London insists that these experiments are not a joke and are seriously regarded by doctors as one of the most promising companies in modern medicine, reports the Daily Mail.

Publishing a data analysis in the journal Nature, Lady Linda Partridge, a geneticist, says research shows that young bloods could allow humans to live without diseases such as cancer, dementia, and heart disease until they are free. death.

His work is part of a wave of studies and trials, including a series of human trials supported by Peter Thiel in a San Francisco start-up called Ambrosia, which injects young blood to older adults. the public.

Professor Partridge's study showed that older mice receiving young blood did not develop age-related diseases and maintained a clear cognitive function, while younger ones receiving older blood saw Reverse effect.

This is the proof, she says, that blood must be studied more closely in animals to identify molecules that maintain physical health.

"The identification of these is a priority for research," says the study.

"The convenient accessibility of the human microbiome and blood system makes therapeutic manipulation particularly interesting, but animal research is needed to establish the long-term consequences and possible side effects."

Professor Partridge and co-authors Joris Deelen and P. Eline Slagboom add: "[Blood] is the most accessible tissue and therefore the most studied, but it is much less used in animal studies.

"It will be important to develop blood-based blood risk biomarkers, aging characteristics, and responses to animal interventions."

This is hardly the first study to show such an effect.

The Ambrosia trials involved 70 participants. All those involved were at least 35 years old and had paid $ 8,000 (£ 6,200) to participate in the experiment from their pocket.

They received plasma – the main component of blood – from volunteers aged 16 to 25 years.

The researchers noted improvements in biomarkers of various major diseases, also known indicators for certain conditions.

This included a 10% reduction in blood cholesterol, which high levels are known to cause heart disease.

Scientists have also found a 20% reduction in proteins called carcinoembryonic antigens.

These can be seen in large numbers in people with various forms of cancer, says the website, but it remains to be seen if.

The younger blood has also helped halve amyloid protein levels, which form toxic clumps in the brains of patients with dementia.

In particular, a 55-year-old patient with early-onset Alzheimer's disease began to show an improvement in his condition after a single transfusion.

Another woman, slightly older, with a more severe Alzheimer's pathology shows similar improvements, reported the start-up.

Scientists in Ambrosia envision a world in which older people receive two injections a year.

However, he suggested that some of his effects could have been imagined by those who were desperate to get results after paying so much.

Scientists have long studied the effects of young blood on animals, but have encountered several results.

Previous research in the United States has suggested that blood from human umbilical cords could be the key ingredient of a drug called "fountain of youth".

The team at Stanford University has discovered that a protein found in plasma can reverse the effects of age-related mental decline.

However, the experts at The Ottawa Hospital made very different findings last July. They noted that blood donation among young women may be related to lower survival rates among recipients.
