Secretory Leukoprotease Inhibitor: A Native Antimicrobial Protein in the Innate Immune Response in a Rat Model of S. aureus Keratitis

Figure 1

Immunolocalization of SLPI at 48 hours in corneas with S. aureus keratitis, epithelial defect, and control.

(a) cornea infected with S. aureus displays increased SLPI immunoreactivity and neutrophilic infiltration in the epithelium (arrowheads) and stroma (asterisks) (800× magnification)

(b) cornea with epithelial defect displays some positively staining cells in the epithelium (arrowheads) and stroma (asterisks) (400× magnification)

(c) control cornea does not display immunostaining (400× magnification)
