From: Fipronil induces lung inflammation in vivo and cell death in vitro
von Willebrand Factor expression in mice lungs. Lungs from control groups (a-b) show normal vWF staining (arrows) in endothelium of blood vessels (BV) but not in bronchiolar (B) epithelium. The oral treatment with fipronil (c-d) caused inflammation but the expression of vWF (arrows) in blood vessels (BV) remained unchanged. The intranasal fipronil (e-g) showed increased expression (arrows) in alveolar septum (e), endothelium of blood vessels (f-g) as well as the vascular cells. Note vascular cells (lightening arrow) attaching to the endothelium (f). Bar: 100 μm
