Find out radical cures HIV / AIDS
Scientists discovered the HIV virus continues to multiply inside the body even if they are not found in the blood after the patients were antiretroviral treatment.
Article this may explain why HIV virus quickly flare up again after the patients stop taking the drug and also causes the doctors can figure out how to treat the root of the disease.
the strong antiviral medications seem to have can eliminate HIV virus from the blood of most patients after treatment so, their blood tests will not detect the virus.
However, the reality of HIV continues to grow in a viral reservoir inside in the lymphoid tissue in the human body at that time. And it will "quickly grow back" in the blood after patients stop taking the drugs.
The scientists came to the conclusion that the potential risk of cells infected or potentially continued HIV replication at low reservoir will survive the virus during treatment with antiviral drugs. Scientists have long said that these places contain the cells were infected for a long time instead of new cells infected.
It is because of these cell without being detected viral genetic mutations that arise when HIV complete their growth cycle.
Moreover, most of the patients are not drug-resistant mutants appear - something likely to happen in the case of HIV growth when drugs.
the study is published in the journal Nature analyzing the viral sequences in a variety of cell samples and lymph nodes of the 3 blood tests for HIV-infected patients - patients who are no longer detected the HIV virus blood.
the scientist Dong Pyou Han, 58, recently sentenced to 4.5 years in prison when using rabbit blood to replace blood who attempt to "pretend" that they have found a cure for HIV. He also was ordered to repay $ 7.2 million government research grants.
The scientists found that the virus reservoir is constantly replenished by the low level viral replication in the lymphoid tissue.
The cells infection then moves from "the protected haven where" and enter the bloodstream. Therefore, infected cells inside the lymph tissue can still produce new viruses. They can also infect new cells and added to the viral container. That is why these drugs can not completely purify the body contains cells potentially infected and simultaneously destroy all the virus.
Experts have used a computer model number of measurements to track the virus and the infected cells to proliferate in the middle shelters, and even if they move within the body.
this model shows that HIV developed in places where the concentration of drugs lower virus in the blood. So the researchers concluded that it is important to take antiviral drugs can be high concentrations to all places where HIV can develop in the body.
Thus drugs penetrate the "shelter newly discovered "will be able to eliminate the virus reservoir, thereby helping the medical community closer to finding a cure for the disease of the century.
" now we have cures Apartments this disease. The problem is to bring the drug clinically effective concentration to the location of the virus continues to replicate inside the patient's body "- Dr. Steven Wolinsky, an infectious disease research at the Feinberg School of pharmacy university Medicine at Northwestern and the study's authors said.
co-author of the study - Dr. Angela McLean, professor of mathematics student at Oxford university, said: "the interesting thing of this study is that it really changing the way we all think about what is happening to the patient receiving treatment. It helps explain why the method to eliminate the disease drives fail ".
