FcγRIIA tg × γ-KO mice show abnormal lung pathology when compared with wild-type controls.
Lung sections (H&E, 100 ×) of FcγRIIA tg × γ-KO mice show intravascular fibrin precipitation and thrombus formation on the arterial side of the pulmonary circulation (A, arrows), whereas wild-type mouse lung sections show no thrombus formation (B).
