ICS and flow cytometry analysis of restimulated T cells from SARS subject 1 at 11 years post-infection. Percentages of CD8⁺IFNγ⁺ responses (left panels) and CD8⁺CD107a⁺ responses (right panels) of (A) unstimulated, (B) M29_147–155-stimulated, (C) N53_266–275-stimulated T cells are as indicated in the upper right quadrant of each dot plot. Percentage CD8⁺ IFNγ⁺ cells shown represent the percentage of IFNγ-producing cells in the total T cell population (after gating the CD3⁺ cells) which were in vitro expanded in the presence of M29_147–155 and N53_266–275 peptides.
