Scientists from Canada have invented a special vaginal implant, which reduces the risk of sexual transmission of HIV. Thanks to this technology, the number of cells that can attack the virus, is reduced several times.
Human immunodeficiency virus remains one of the main problems in the world of science and specifically medicine. According to the world health organization, in 2016 there were approximately 36.7 million people with HIV infection.
The new development is based on the results of the study of the spread of HIV in Kenya in the 90-ies. Then the scientists found that certain local sex workers can maintain resistance to infection, even though not used barrier methods of contraception. Researchers have suggested that this leads some peculiarities of T-lymphocytes in the body women. Known as T-helper cells, the cells usually become the main target for the virus.
Due to the connection with the protein CD4 on the surface of the above cells, HIV can get inside and destroy them by themselves or by other cells of the body. HIV, as you know, replicates mainly in activated cells. That’s why scientists came to the conclusion that many T cells of the vaginal mucosa of these women when interacting with the virus remain “dormant” and are not activated.
