Resistance to the AIDS virus and vaccine against specification

An international study published in nature magazine (nacher) in its latest edition that HIV evolves quickly to avoid the impact of the human immune system. The study showed how difficult it is to develop a vaccine able to adapt quickly to the changing nature of HIV. researchers showed, led by Philippe goldr of the British Oxford University how the virus can adapt quickly to fight human genes that control the immune system molecules capable of targeting the virus to destroy it.

And HIV caused the death of about 25 million people so far, it is estimated that infected some 33 million people.

However, the virus does not eliminate infected at the same rate.

The average time a person carrying the virus until the symptoms of HIV/AIDS in emerging it is 10 years.

Some symptoms of the disease after only 12 months of carrying the virus, while others remain healthy for 20 years before symptoms of the disease.

This rate is controlled by genes that control key immune system molecules called generators to produce white blood cells "HP the ASX".

The researchers studied the genetic sequences as well as generators for the production of white blood cells "HP of any" virus in more than 288 people in several countries including United Kingdom, Australia and South Africa and Canada and Japan.

Scientists found that the transitions from one generator effect equation to produce white blood cells that grow in abundance in the growing population have the gene.

For example, the testator "51" is particularly effective in controlling HIV, unless there is in its property to "shift cycle".

The study found that in Japan, where is the proliferation of the testator "51" two thirds of people living with HIV without the testator extremists armed with a "shift to escape".

While living with the disease in the United Kingdom where the testator less prevalent, the proportion of those who acquire the virus that they feature the "shift to drop much lower, ranging from 15% to 25%.

Goldr says that it shows the ability of the virus to adapt to the activity of the immune system in people who are most able to contain the virus, and this happened in just two decades.

Relieves goldr of pessimism about the results, feeling that the virus will win his battle against attempts to eliminate it.

Goldr says "the situation is not necessarily the case, as it may be that while the virus transformation appear different immunological activities and may be more effective."

"The conclusion that emerge from the study is that when we get an effective vaccine must be" converted "regularly to adjust to the" transformation "of the virus, just as we do now in flu vaccines.
