Recent discoveries in biochemistry and genetics have enabled scientists to learn more about the behavior of some dangerous viruses. As it turned out, more than half of adults over 40 years old are infected with cytomegalovirus, the existence of which many do not even suspect.
The veil of secrecy was lifted by Russian scientists from the Institute of Bioorganic Chemistry, together with Canadian geneticists and their colleagues from several Russian scientific centers. With relative safety for humans (in some cases, it is still dangerous), the virus has a unique ability to penetrate cells, remaining invisible to the immune system - as if bypassing it.
This "trick" became possible due to the fact that the virus "turns off" some genes responsible for the protection of cells. The security of the virus is still deceiving. With a significant weakening of the immune system, it works like a time bomb, provoking serious diseases with a fatal outcome, for example, brain cancer.
Now scientists are faced with the task at all costs to suppress the "invisibility" of the insidious virus and learn how to remove it from the body. It is not excluded that other, more insidious congeners also have the “invisible hat”. Knowing this mechanism, scientists will be able to create an effective system of protection against dangerous infections.
