Newspaper in Toronto June 20 (Xinhua Du Huabin) of Canada and the United States, researchers found a new method of treatment of AIDS. New methods will be targeted chemotherapy with the more commonly used in the current highly active antiretroviral combination therapy for treatment of AIDS has provided a new possibility.

According to the scientists involved in research presentations, this new treatment can kill wandering around in the body of the virus, also hidden in immune cells to kill the virus. The value of the results of the study lies in its study of AIDS treatment around the world the scientists pointed out the way forward, in order to find a new innovative treatment of AIDS foundation.

To date, the efficacy of anti-AIDS treatment has been less than ideal because the virus hidden in the immune system cells, while the currently used highly active antiretroviral therapy on immune cells hiding in the virus can not do anything. Canada and the United States, the researchers successfully identified a virus that hide the cells, found the virus to evade the existing treatment of the "stealth" mechanism.

To participate in the research work of McGill University professor of blood基恩罗迪scientists believe that the first results of the study prove that the so-called latent pool of HIV is not due to lack of effectiveness of anti-retroviral drugs, but because the virus hidden in two different types of long-lived memory CD4 immune cells. Latent pool of HIV There are several types, each type of latent pools require different treatment methods to eliminate them. Once the virus hidden in the potential pool of these cells, they will rely on their produce. If the cells survive, the virus can survive, but if the cell death, the virus can not survive. Therefore, the elimination of these immune cells can kill one of these hidden viruses. Existing highly active anti-retroviral therapy can kill the virus circulating in the body, but were unable to deal with hidden cells in the latent pool of virus.

The auspices of the University of Montreal research, Professor塞卡里said the study results and for the treatment of leukemia is similar to the strategy adopted, which is also targeted chemotherapy, and at the same time with a combination of targeted immunotherapy. This method can kill the virus cells, as well as the immune system time to stay healthy cell regeneration.

The researchers believe that the results obtained for the development of a new anti-HIV treatment provided an important option, but to enter the practical application of a number of years also needs further research.
