Frequency (%) of CD4⁺ (T_H) cells positive for the signature cytokines (a–e) and homing molecules (f–i) of the different T_H subsets (T_H1, T_H2, T_H17, and T_H22) in peripheral blood mononuclear cell samples from control subjects (N = 11) and patients with abdominal aortic aneurysm (N = 12). The analyzed samples were cultured for 48 h in the absence of stimulus (white) or in the presence of anti-CD3, anti-CD28, and anti-CD2 antibody-coated beads (grey), with the addition of PMA plus calcium ionophore in the last 6 h of incubation. P < 0.05; ^∗comparison between stimulated and unstimulated cells (Wilcoxon matched pairs test); ^#comparison between control cells and AAA peripheral cells (Mann-Whitney test).
