Histology of lung infiltrates: C57BL/6J mice (A, B), LTβ-KO (C) and plt/plt mice (D) were i.p. immunized and i.n. challenged with OVA (B, C, D) or PBS (A). Lungs show peribronchial and perivascular accumulation of eosinophils in mice challenged with OVA but not in those challenged with PBS. Sections were stained with DAB in the presence of cyanide to reveal eosinophil peroxidase activity. Slides were counterstained with H&E. All pictures are at the same magnification (originally photographed at 200x).
