Airway M cells are pathologically induced in the tracheal epithelia associated with lymphoid infiltration in murine models of autoimmune disease. (A) Hematoxylin–eosin staining of the lung of non-obese diabetic (NOD) mice. Bars: 200 μm (left panel) and 50 μm (right panel). (B) Immunofluorescence images of CD3ε (magenta) and B220 (green) of lymphoid follicles associated with the bronchiole of NOD mice. Bars: 100 μm. (C,D) Immunofluorescence images of GP2 (magenta) and Tnfaip2 (green) (C) as well as GP2 (magenta) and RANK (green) (D) in the trachea of NOD mice. Images are representative of three independent experiments.
