Expression of CCR7 and CD62L in Flu-MP* peptide-specific CD8 ⁺ T cells. (A) Phenotypic characterization by flow cytometry in one representative chagasic patient. (B) Significant differences were observed between central memory (double positive cells) T cells (T_CM) and effector memory (double negative cells) T cells (T_EM) (P < 0.008) from chagasic patients (white bars) or healthy donors (grey bars). No differences were found when the frequencies of T_CM and T_EM CD8⁺ T cells were compared between chagasic patients and healthy donors.
