Scientists from the United States were able to transplant the cells of the human immune system a group of mice.As a result of the experiment the mice's immune system began to work on the principle of human immune background.

This can be called a breakthrough in the development of a vaccine against the human immunodeficiency virus.Currently, scientists were able not only to create a vaccine and test it.

human immunodeficiency virus has clinical similarities to the simian immunodeficiency virus (SIV).But at the same time, there are a plurality of functional differences, however the vaccine tested in monkeys optionally be affected in the same way on the person.

When creating vaccines scientists have to solve many prob
lems, the most important of them - is to understand how the virus is struggling with the immune system and why the immune system always loses this fight.

Before the study, the researchers deprived mice, the immune system, they transplanted human bone marrow and a number of tissues, what exactly is not specified.The researchers argue that the mice began to produce antibodies that can fight various diseases.

In this way, the mouse can be subjected to HIV infection and to begin full-scale study of the disease and find effective ways to prevent HIV.

problem of HIV vaccine development was the fact that the scientists for a long time could not understand how the progression of the virus in the body and the mechanisms of immune suppression.Animal studies it was impossible to carry out, since they are not exposed to HIV.In human studies have not performed for obvious reasons.That is why the vaccine has not yet been established.

professor at the University of Massausets Todd Allen noted that at present scientists around the world will be able to conduct a more extensive work to develop a vaccine against HIV.
