Altered Expression of IFN-λ2 in Allergic Airway Disorders and Identification of Its Cell Origins

<div>Immunohistochemical staining of IFN-λ2 in human tonsil, lung, and nasal polyps tissues. Biotinylated anti-human IFN-λ2 antibody was employed to identify IFN-λ2+ cells in the sections from tonsil (b), lung (d), and nasal polyps (f), respectively. Mouse IgG-peroxidase labeled anti-mouse IgG was used as negative control for tonsil (a), lung (c), and nasal polyps (e). Arrows indicate positively stained cells. All sections were counterstained with Mayer’s haematoxylin. Magnification was ×400.</div>
