Scientists have identified another gene that determines the course of COVID-19 German scientists have identified a gene that is associated with the human immune system. and it has a direct impact on the severity of the course of the coronavirus.

This is a gene that encodes a major histocompatibility complex protein HLA.

The function of these proteins is that they bind to other proteins and present them to the immune system..

In their study, scientists tested the HLA genes in 435 people who underwent covid infections in Germany, Spain and Switzerland.. Holders of the gene variant HLA-C * 04: 01, as it turned out, are on mechanical ventilation twice as often compared to other population groups.

At the same time, a gene variant that contributes to the development of severe lesions occurs quite often.. Scientists have identified it in 13-19% of Germans, 15% of Spaniards and 16% of Swiss.

It is assumed that the body does not have time to respond to infection in time due to poor binding to immune cells.. This allows the virus to have time to multiply to critical concentrations, which leads to severe damage to the body..

The presence of another gene variant, HLA-B * 46: 01, also has a severe course of covid, but it is practically absent in Europeans, while it occurs in 17% of the population in Asia.

Scientists in the Netherlands conducted a study that showed that coronavirus vaccines are effective for people with autoimmune diseases. After being vaccinated against coronavirus, the body in autoimmune patients developed about the same amount of antibodies as in healthy people who received the vaccine..

Scientists have already sent a report on the work done to the Ministry of Health of the Netherlands.
