Fig 1 — A: The lymphocyte population was gated from peripheral blood mononuclear cells by drawing (R1) based on the forward/side scatter characteristics. B, C: CD3 expression was analysed on the gated lymphocytes, and the CD3⁺ cells were selected by (R2) for further analysis based on CD4 and CD8 expression. (R3) and (R4) represent the regions used to choose the CD4⁺ andCD8⁺T cells, respectively. D-H: Dot plots representing CD39 and PD1 expression by CD4⁺ andCD8⁺ T cells.
