Frequencies of lymphocyte immunophenotypes in PBMC.

TN: naïve T cells (CD45RO-/CD62L+); TEF: effector T cells (CD45RO-/CD62L-); TCM: central memory T cells (CD45RO+/CD62L+high); TEM: effector memory T cells (CD45RO+/CD62L-); UNS: unstimulated cultures; ML: M. leprae-stimulated cultures; REL: relapsed patients group; MB: untreated multibacillary patients group; CUR: cured patients group; PB: untreated paucibacillary patients group; HC: healthy control group; M: median; IQR: interquartile range (25-75% percentile); PBMC: peripheral blood mononuclear cells. The Kruskal-Wallis test was used for comparison of stimulated cells with unstimulated cells and the Mann–Whitney test was used to group comparisons. p= significance level; ap bp (DOCX)
