Polyarteritis like lesions and arteriopathies in Nppb−/− females.
(A–C) Autopsy of moribund Nppb−/− females revealed mesenteric arterial nodes (black arrows) with partial intestinal necrosis (green bracket) and mesenteric arteries with multiple aneurysms (blue arrows). (D) Aneurysms found in splenic arteries and (E) epicardial hemorrhage in Nppb−/−. (F) HE staining demonstrated marked arterial wall thickening, inflammation of the affected arterial wall and artery occlusion by possible fibrin plug or thrombi (black arrows).
