Lymphoid follicles in the lungs upon air or cigarette smoke exposure. Photomicrographs of lymphoid follicles in lungs of air- and cigarette smoke (CS)-exposed wild type mice and scid mice at 6 months (magnification × 100). (A)-(E) B220 staining (brown = B220 positive cells): (A) air-exposed wild type mice, (B) CS-exposed wild type mice, (C) air-exposed scid mice, (D) CS-exposed scid mice and (E) CS-exposed wild type mice (magnification × 200). (F) CD3/B220 staining (brown = CD3 positive cells; blue = B220 positive cells): CS-exposed wild type mice.
