Scientists of the British Center for Viral Research MRC University of Glasgow conducted a study and explained why part of the world’s population may be immune to COVID-19. In their opinion, the answer lies in the peculiarities of their genetics: the mutation in the OAS1 gene corresponds to this. The results of the study are published in the SCIENCE journal.
Previously, intracellular antiviral protection can not only be displayed as natural “immunity” to SARS-COV-2, but also suppress the replication of viruses, that is, reduce the severity of the disease. Researchers who used mainly sequencing method managed to find out that the option of the OAS1 gene from part of people can “recognize” some typical signs of viruses inherent in the number of COVID-19.
This is a renulated gene – that is, one molecule of fat is attached to whose protein. If OAS1 is not rented, it means that it actually “does not know how to” respond to the causative agent of coronavirus and cannot send “anxious signals” of the immune system.
Previously, an infectious physician, Candidate of Medical Sciences Ilya Akinfiyev, said that at the beginning of a pandemic, the main fear that spread in society was that the re-infection of COVID-19 could sharply increase the chances of the patient for a fatal outcome. However, according to the specialist, such an effect has a dengue fever, and not coronavirus.
