Identification of IL-25 receptor–expressing cells in aortitis in Il1rn^−/− mice. IL-17RB was expressed in CD11c⁺, Mac2⁺, B220⁺ and GL3⁺ cells—but not CD3⁺, CD86⁺, CD206⁺ or Gr1⁺cells—in a local lesion of aortitis in Il1rn^−/− mice (12 weeks old). Scale bars = 20 μm. Arrowheads = Cell surface marker-positive IL-17RB⁺ cells
