Figure 2

Frequencies of Ki67⁺ PD-1⁺ and Ki67⁺IL-17⁺ cells are elevated in the circulating T-cells in patients with vasculitis. (a–c) Representative flow contour plots and frequencies of (a) Ki67⁺ cells, (b) Ki67⁺PD-1⁺ cells, and (c) Ki67⁺IL-17⁺ cells within the CD4⁺ T-cell population in patients with systemic vasculitis, cutaneous vasculitis, and healthy donors (HDs). (d–f) Representative flow contour plots and frequencies of (d) Ki67⁺ cells, (e) Ki67⁺PD-1⁺ cells, and (f) Ki67⁺IL-17⁺ cells within the CD8⁺ T-cell population in patients with systemic vasculitis, cutaneous vasculitis, and HDs. Data indicate mean ± SEM. *p < 0.05.
