The USA has created effective vaccine потив cancer


Researchers have held testing about 100 thousand chemical compounds which could increase efficiency of chemotherapy in fight against a melanoma – skin cancer. Scientists of Skrippsa Research institute in the USA have proved efficiency of new vaccine against a melanoma in experiments on mice. Added to the medicine intended for fight against tumors diprovotsy, being adjuvant, that is the substance stimulating immunity. Results of test are published in the Proceedings of the National Academy of Sciences magazine, Lenta.ru on Tuesday, September 11 reports. It is noted that researchers have held testing about 100 thousand chemical compounds which could increase efficiency of chemotherapy in fight against a melanoma – skin cancer. It has allowed to find the substance called diprovotsimy which contacts toll-like receptors – the proteins activating the cellular immune answer. In an experiment scientists used mouse model of an aggressive melanoma. Cancer tumors have been genetically modified for synthesis of egg white of an ovalbumin which plays a role of the antigen causing the immune answer. Animals have been divided into three groups according to various types of therapy. One received injections of an ovalbumin and anti-PD-L1 – medicine which prevents resistance of cancer cells to the protective systems of an organism. In the second group to rodents the injection of an ovalbumin, anti-PD-L1 and a diprovotsim was carried out. In the third group has been replaced by diprovotsy with other type of adjuvants – alum. Each mouse received two doses of medicine, at the same time between injections there passed week. Within 54 days of a mouse from the second group showed absolute survival, rodents from the third group – 25 percent, and in the first have died everything. Moreover, scientists didn't manage to initiate repeatedly growth of a melanoma at the animals receiving diprovotsy. Successful tests on mice don't mean that vaccine with new adjuvant will be so effective in case of application by people. Future tests will have to prove it. Earlier scientists have found the gene - "zombie" protecting from cancer in elephants. Earlier the gene of LIF6 was considered as nonfunctional. But it has turned out that he is capable "to come to life" and be responsible for coding of the protein destroying mitochondrions. News from the Correspondent.netv of Telegram.
