CoV2+ individuals exhibit an aberrant T cell phenotype 5 months after the first detection of infection: Heparinized blood obtained from CoV2- and CoV2+ individuals was stained with anti-CD3, -CD4, -CD8, -CD45RA, -CD62L, CD27, -CD28, -CD57, -PD-1 and -CX3CR1 antibodies. (A–C) Cells were analyzed for various T memory cell subsets as indicated. (A) Gating strategy for T cells is shown (B, C) Percentages of T memory cells are shown. (D–F) Percentages of PD-1⁺, CD57⁺ and CX3CR1⁺ cells in CD3⁺CD4⁺CD45RA^-CD62L^-CD27⁺CD28⁺ T memory cell subset (G–I) Percentages of PD-1⁺, CD57⁺ and CX3CR1⁺ cells in CD3⁺CD8⁺CD45RA^-CD62L^-CD27⁺CD28⁺ T memory cell subset is shown. For all, each dot in the plots depicts data of each individual donor, the plots include observations from 25^th to 75^th percentile. The horizontal line represents the median value. *p < 0.05; **p < 0.005 NS, Non-significant.
