Corona Calls for 07.24.2023 – Genetics and COVID

Discussed in this episode:

  • New research published in Nature examined if people who got infected without showing symptoms had something in common genetically. They did: a mutation on the  HLA-B (that’s short for Human Leukocyte Antigen) gene. In the laboratory, T-cell samples collected from those people *before* infection reacted strongly to SARS-COV2, suggesting the mutation helps the immune system respond to other, less-serious coronaviruses in a way that is also effective against COVID-19.
