Circulating Th22 and Th9 frequencies in each group. (a) CD4+ T cells were gated by flow cytometry. (b) Representation of intracellular cytokine staining of Th22 and Th9 from each group. (c) The frequencies of Th22 were markedly higher in patients with acute myocardial infarction (AMI), unstable angina pectoris (UAP), and stable angina pectoris (SAP) than those in the control group (Cont). (d) The frequencies of Th9 showed no differences among these groups. *P < 0.05 versus control, **P < 0.01 versus control, ^# P < 0.05 versus SAP group, and ^## P < 0.01 versus SAP group.
