Flow cytometric plots for Treg evaluation.

<p>Gating on CD3+/CD4+ cells (left panel) was followed by subsequent gating according to the CD25 and CD127 expression (right panel). Tregs were defined as the CD4⁺CD25^highCD127^low/- -cells (P3). (A) A patient with high Tregs/long T cell telomere length. % Tregs of total PBL: 1.7; % Tregs of CD4+ cells: 7.7; T cell telomere length: 0.65. (B) A patient with low Tregs/short T cell telomere length. % Tregs of total PBL: 0.2; % Tregs of CD4+ cells: 4.8; T cell telomere length: 0.33.
