Sensation! Scientists have learned how to protect against AIDS!

The researchers found that the characteristics of the structure of the blood can increase a person's chances to avoid contracting HIV. This conclusion was Swedish and Canadian scientists.

Doctors examined the blood cells, and found that on the surface are special molecules, designated Pk. The concentration of these molecules can be divided people into different categories, such as blood type or Rh factor. A large number of molecules Pk reduces the sensitivity to the AIDS virus, and a small number or absence greatly increases vulnerability to HIV infection, according to RIA Novosti.

We found that the expression of molecules Pk a strong influence on susceptibility to HIV-1. Thus, Pk is a novel endogenous factor that can give protection against HIV - the authors of the study. However, Dr. Don Branch of Canadian Blood Service warned that even belonging to a stable blood group did not give an absolute guarantee, but in certain cases it may block the development of the virus.

At the same time, Professor Martin Olsson from Lund University in Sweden believe that the high level of molecules Pk is a completely new type of cell protection from HIV infection. In this regard, the scientist in favor of continuing studies of blood that have proven useful.

Note that shortly before that American physicians from Northwestern University in Chicago have opened new properties AIDS. The experimenters found that immunodeficiency virus can enter the body much more easily than previously thought. As written Dni.Ru, HIV can quickly overcome the protective mucosal barrier and hit the immune system cells.
