Figure 5: Levels of Interferon-α (IFN-α) in porcine corneal tissues.

The cultured corneas were infected with 10⁷ PFU of HSV-1 (17-GFP) or mock infected. Representative IHC sections show the presence of HSV-1 (in green) and IFN-α (in red) in corneal epithelial cells (stained with DAPI in blue). Scale bar for all images: 50 μm.
