Expression of interleukin (IL)-17A and IL-17E receptors on intestinal myofibroblasts. (A) IL-17RC and (B) IL-17RB were detected by immunoblotting on lysates of myofibroblasts isolated from uninflamed areas of strictured (Strict uninfl) and non-strictured (Non-strict uninfl) gut of six patients with fibrostenosing Crohn’s disease (CD) and from normal gut of seven healthy control (HC) subjects. Each example shown in the left panels is representative of experiments performed in all patients with CD and all HC subjects. Blots were stripped and analyzed for β-actin as an internal loading control. In the right panels, densitometry of IL-17RC and IL-17RB expression normalized for β-actin is shown. Results are mean ± SEM. au, Arbitrary units.
