We analyzed levels of pro-inflammatory IL-17 members (IL-17A, IL-17B and IL-17F) as well as their soluble common receptors (IL-17RA and IL-17RB) in clinically staged AE patients, that is, cured, stable, and progressive AE, and in infection-free controls. The gene discussed is IL17RB; the disease is acrodermatitis enteropathica.
