Distribution profile of T cells in healthy donors. (A) Frequency and (B) absolute number of peripheral blood CD4⁺ and CD8⁺ T cells from healthy individuals as assessed by flow cytometry. Frequency of memory (C) CD4⁺ and (D) CD8⁺ T cell subpopulations according to the CD45 and CD62L expression [central memory T cells (T_CM – CD45RA⁻ CD62L⁺), effector memory T cells (T_EM – CD45RA⁻ CD62L⁻) and terminal effector memory T cells (T_EMRA – CD45RA⁺ CD62L⁻)]. The values were statistically significant with p-value < 0.001 (***) and p-value = 0.003 (**).
