Characterization of CD4+ T Cell Subsets in Patients with Abdominal Aortic Aneurysms
Figure 2
Paraffin-embedded tissue sections of AAA lesions () were immunohistochemically labeled (brown) for CD3+ cells (a), CD8+ cells (b), IL-4+ cells (c), IL-17+ cells (d), IL-23+ cells (e), and IL-22+ cells (f) in follicle-like structures located in the adventitia and media of abdominal aortic aneurysm lesions. (g) and (h) show negative controls (without the primary antibody) at different magnifications.
