Academician of the Russian Academy of Sciences, Director of the Pasteur Research Institute of Epidemiology and Microbiology Areg Totolyan named the reasons for the immunity of some people to coronavirus. About it report “News”.
According to him, people with high levels of interferon alpha, with a high content of lymphocytes in the blood and carriers of some genetic markers have increased protection. There are other factors, but research on them is just beginning.
Totolyan noted that the first protective factor is the level of local protection. Coronavirus infection enters the body through the upper respiratory tract, and if the body has a high level of interferon alpha, the risk of infection is reduced. Interferon alpha is a molecule that is synthesized and produced by cells of the immune system and has a direct antiviral effect.
The second factor is genetic markers that encode the immune response in humans. “We identified two protective alleles (different forms of the same gene – approx. “Lenta.ru”) and one predisposing to the disease. These are the very first results of the study, it continues, and in the active phase, ”Totolyan said.
In addition, a high lymphocyte count indicates that a person is less likely to become infected, and if he does get sick, there is less risk that the disease will be severe.
Earlier, Deputy Director for Research of the Central Research Institute of Epidemiology of Rospotrebnadzor, Corresponding Member of the Russian Academy of Sciences Alexander Gorelov said that the tense situation with the coronavirus in Russia could persist for another three years, since herd immunity has not yet formed among its residents. According to the expert, the country should definitely expect new outbreaks of infection, since the immunization rate in the country has not even reached 60 percent.
