Scientists were able to cure cancer in patients bad!
revolutionary method of immunotherapy has been developed
American researchers, which allowed the cure of patients deemed hopeless cancer. Site publishes an article explaining podrobnosti.S preliminary results of testing experts familiarized the audience during a meeting of the American Association for the Advancement of Science, which was held on February 14, 2016-th. According to the creators of the immunotherapy, it helped to cure patients who were considered completely hopeless.
The problem with cancer is becoming more urgent every year. Annually in the world recorded 6 million new cases of malignant tumors. Now oncological problems rank third in the world among all causes of death. Cancer is particularly relevant for people whose age is "stepped" the mark of 50 years. So in view of the aging population in developed countries the difficulties of this kind will only exacerbate.
< save millions of lives, as the new discovery will involve experts,. The issue of human protection against their own malignant transformation of cells lies on shoulders T-lymphocytes. But in some cases, the immune system does not allow opposition to remove the tumor. Researchers have reported a method which leads to an increase of antitumor activity of immune cells.
Participated in the experiment people with blood lymphocyte tumors that were resistant to chemotherapy. Patients took blood samples and are identified T-lymphocytes. Then neutralized using lentivirus gene chimeric antigen receptor (CAR) was inserted into their DNA. "Improved" cells were administered to patients, and after a few weeks in 27 of 29 patients failed to detect cancer cells. < A number of patients had the luck to get rid of one kilogram of tumors.
The rapid destruction of tumor cells has led to some complications, such as fever. Subsequently, however, the dose has been adjusted, and such problems could be avoided. In the future, scientists from the United States want to learn how to use this technique for the treatment of other cancers, such as lung or breast cancer. They themselves say that the new method, which combines synthetic biology, gene therapy and cell biology, has a chance to recover the most seriously ill patients. At the same time, they recognize that this immunotherapy is still not universal and in some cases may require a different approach.
In any case, research in this direction will be continued. Moreover, the new method has attracted attention from around the world.
