Fig 1: Percentage of NKG2A+ and NKG2D+ cells in the CD3+CD56- T population. (A-D) Gating strategy for the selection of the CD3+CD56- T population: (A) Gating of lymphocytes by forward and side scatter. (B) Selection of single events. (C) Selection of CD3+ events. (D) Selection of the CD3+CD56- events in the CD3+ lymphocyte gate. (E, F) Selection of the NKG2A+ CD3+CD56- T cells by dot plot (E) and histogram plot (F). (G) Differences in the percentage of NKG2A+CD3+CD56- T cells in controls, CMC and CSC participants. (H, I) Selection of the NKG2D+ CD3+CD56- T cells by dot plot (H) and histogram plot (I). (J) Differences in the percentage of NKG2D+CD3+CD56- T cells in controls, CMC and CSC participants. CMC/CSC: convalescent of mild/severe COVID-19 individuals. Boxes represent the 25 and 75% quartiles, lines represent the median of the distribution, and whiskers are the maximum and minimum values of the distribution.
