Cells of the transposed IPS in the patient's brain in Japan


It's a world of hope for people with Parkinson's disease. Researchers from the University of Kyoto, Japan, said on Friday, November 9, that successfully copied 2.4 million iPS cells in the brain of a patient with Parkinson's disease. "Induced pluripotentiary stem cells" or French induced pluripotent cells).

The operation last month lasted for three hours, says the medical team. The patient, his fifty-year-old man, was well tolerated. Now he is being monitored for two years. If there is no problem for six months, doctors also add 2.4 million additional strains, which is at the right of the patient's brain.

Pluripotent stem cells

The second most common neurodegenerative disease in the nervous system after Alzheimer's disease Parkinson's disease affects approximately 200,000 people in France and more than a million in Europe: 8,000 new cases are reported every year in France. According to the US Parkinson's Disease Foundation, there are 10 million Parkinson's patients in the world.

A description of the progressive loss of neuron in the gray nuclei of the brain Parkinson's disease leads to gradual loss of control of the motion and other motor signs such as tremor and stiffness in the hands. At present, accessible treatment "does not slow down the development of the disease, it improves symptoms," says Parkinson's Disease Foundation.

The new WTO treatment, consisting of healthy donors, provides new expectations for patients. Indeed, they are distinguished as pluripotent: neurotransmitters, dopamine-producing neurons that are involved in engine management by brain transplantation.

Clinical studies on seven patients were published

This successful essay could be the latest in Japanese scientists. Last July, Kyoto University announced the launch of clinical trials with seven people aged 50 to 69 years. "I congratulate patients for their courageous and clear participation," said Jan Takahashi, NHK public on Friday.

This clinical trial is based on an experiment carried out in apes with human-born cells and was published in Nature magazine in August 2017. According to researchers, this transplantation has improved the power of primates with Parkinson's movement. The cells that injected injections into the brain of the preparations did not develop cancer for two years.
