Figure 2

Eosinophil infiltration of conjunctiva. Confocal images of tissue sections from each treatment group stained for eosinophil-specific major basic protein (green) and counterstained with propidium iodide (red). A) No sensitization, no challenge (NS/NC; naïve animals); B) Sensitized, challenged (S/C); C) S/C + drug vehicle; D) S/C + 0.1% topical olopatadine; E) S/C + 0.025% topical alcaftadine. Major basic protein staining is most pronounced in sensitized, challenged animals without drug treatment (B and C).
