Employees of the RIKEN Research Institute (Japan) suggested that the relatively low mortality rate from COVID-19 may be associated with the genetic characteristics of the population of the Land of the Rising Sun. This was reported by The Japan Times newspaper, which gained access to the research results.
Scientists have found that 60% of the inhabitants of Japan and only 10-20% of the population of Europe and the United States have the HLA-A24 molecule, which helps T cells inside the leukocyte to identify a harmful virus and destroy it. They then analyzed the coronavirus spike protein, identifying an antigenic component, or epitope peptide called QYI, which binds to the HLA-A24 molecule, activates T cells and encourages them to multiply.
Similar features, the researchers point out, are inherent in seasonal coronaviruses. This confirms the existence at the molecular level of cross-immunity against common coronaviruses and against the virus caused by COVID-19.
Previously, the sharp decline in the incidence of COVID-19 in Japan has prompted speculation about the “self-destruction” of the coronavirus, as well as that success in the fight against the pandemic may be associated with the legendary discipline of the Japanese.
