Antigen-specific CD8 T cells against SARS-CoV-2
In this project, we characterized the antigen-specific CD8 T cells of people from five groups. We used HLA:A2 tetramers loaded with the GILGFVFTL (Influenza) or YLQPRTFLL (Sars-CoV-2) peptides to label cells. Cells were sorted based on CD3+CD8+TTM+. We distinguished between four groups: 1. SARS2-TTM+ cells 6 months after infection, 2. SARS2-TTM+ cells 1 motnhs after 2nd vaccination with the Pfizer vaccine, 3. SARS2-TTM+ cells of people that were both infected and vaccinated and 4. FLU-TTM+ cells. Cells were sorted and analyzed by bulk RNA sequencing. Overall design: We characterized the antigen-specific CD8 T cells of people from five groups.
