Histologic assessment of tissue inflammation after intranasal Ad inoculation. After intranasal delivery of AdLuc, mice were sacrificed at days 1, 3, 7 and 12 and the organs were fixed, processed, and stained with H&E. Open arrow: inflammatory infiltrates in the liver (day 7) and lung (days 1, 3, 7 and 12). These microhistographs are representative of two mice per time point. Magnification: ×20.
