CD8A and COVID-19: The authors also identified B cell epitopesfor SARS-CoV-2 antibodies in the serum of ten COVID-19 patients.259 Two HLA-A*02:01-restricted CD8+ Tcell epitopes specific for SARS-CoV-2 have been identified: A2/S269–277 (YLQPRTFLL) and A2/Orf1ab3183–3191 (FLLNKEMYL).95 T cells correspondingto the former epitope are detected at comparable frequencies in acuteand recovering patients (and at levels above those for uninfecteddonors) though with a weaker response than for influenza or Epstein-Barrvirus A2 sequences.
