Immunophenotype of PA T cells from PBMC cultured for 96 h in the presence of anti-CD3 (PA). Then T cells were cultured for another 48 h in medium alone following primary stimulation (PA + medium). Furthermore, PA T cells were restimulated by anti-CD3 (PA + CD3) or IL-2 (PA + IL-2). CD3 bars show the percentages of T cells among all lymphocytes, whereas percentages of CD95, CD25, HLA-DR, CD28 and CD69 refer to all T cells (*P < 0·05 compared to PA). , PA;
