The Chinese are the first in the world to experience gene editing on an adult

               

Chinese scientists were the first in the world to introduce genetically modified cells into an adult’s body using CRISPR / Cas9 technology. The edited cells were introduced to a patient with aggressive lung cancer on October 28 of this year by a team of scientists from Sichuan University in Chengdu, reports Science Alert .

Experts removed the patient’s immune cells from blood samples, and then used CRISP technology to disable one of the genes. He was responsible for the PD-1 protein, which slows down the immune response of cells and allows cancer to actively progress. Genetically modified cells were cultured in the laboratory, and then reintroduced to the patient.

In theory, they should multiply in the body of the patient and attack cancer. In the near future, the procedure is planned to be repeated. A total of 10 people will take part in the experiment. They will receive from two to four injections of the edited cells.

According to Western media, this experiment can cause a genetic race between China and the United States. In America, similar studies were approved this summer, but they will not begin until 2017. While China planned for March 2017 new trials of gene modification of human cells to combat cancer of the kidneys, bladder, prostate. True, these tests have not yet received official approval.
