Phenotypic Characterization of Circulating CD4⁺ T Cells in ANCA-Associated Vasculitis

Figure 3

Percentage of Th17 cells (CD183⁻CD196⁺) of the total number of CD4⁺ T cells in patients with ANCA-associated vasculitis. In (a), the patients are divided according to their tendency to flare. The patients with tendency to flare also have a tendency to have higher percentage of Th17 cells compared to the patients with one or no flares. In (b), the AAV patients are divided by their prednisolone dose at the time of sampling. Patients with 5–10 mg dose per day have significantly higher levels of Th17 cells compared to patients with 0–5 mg prednisolone per day.
