Scientists from the National Research University Higher School of Economics have compiled an atlas of 11 strains of the coronavirus.
The goal of the researchers was to see how HLA molecules (with their help, molecules that propagate antibodies, obtain information about the virus) cope with mutant covid proteins. They analyzed 11 strains of the coronavirus, from the British alpha to the Peruvian lambda. As a result, scientists obtained data on the interaction of hundreds of HLA variations with tens of thousands of different viral proteins.
The CoViD-19 T cell atlas describes in detail about each strain: how many mutations, which mutations they are, and how they are perceived by HLA molecules. The general conclusion of scientists: the picture of cellular immunity is quite favorable.
“Our study did not find a single variant of the HLA genotype that would be significantly negatively affected by viral mutations, in a significant way. This means that even under conditions of reduced antibody efficiency, T-cell immunity continues to work effectively, ”LIFE quotes Alexander Tonevitsky, Dean of the Faculty of Biology and Biotechnology at the Higher School of Economics.
Earlier, Russian scientists have created a robot for contactless testing for coronavirus.
