Characterization of CD4⁺ T Cell Subsets in Patients with Abdominal Aortic Aneurysms

Figure 1

Frequency (%) of CD4⁺ lymphocytes (T_H cells) positive for the signature cytokines and homing molecules of the different T_H subsets (T_H1, T_H2, T_H17, and T_H22) in mononuclear cell suspensions of abdominal aortic aneurysm lesions (). The mononuclear cell suspensions were expanded in vitro for 15 days and left without stimulation (white) or were stimulated by PMA plus calcium ionophore for the last 6 h of incubation (grey). ; Wilcoxon matched pairs test.
