Ag NWs produce TNF-α-positive cells at Day 1. Tissue sections recovered at 1 day post instillation of sham control (A-C), S-Ag NWs (D-F) or L-Ag NWs (G-I), and stained with TNF-α immunohistochemical stain. Panels are Brightfield microscopy images of responses in tissues from rats instilled with a single dose of 1.0 mg/kg Ag NWs. Brown cells (indicated by arrows) in the alveoli (left), terminal bronchioles [TB (middle)], and pleural region (right) are TNF-α-positive. Scale bar is 25 μm.
