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.
