(A) Concentration of antibody by isotype in corneas from
immunologically naive CD-1 mice reflecting healthy, scratch control (24 hours),
and HSV-1 infected corneas (n = 6–7 cornea
pairs/group; 2–3 independent experiments). Statistical differences were
determined by one-way ANOVA with Student-Newman-Keuls multiple comparisons
tests. (B) Representative photos from SD-OCT imaging of the
anterior segment of healthy and HSV-1-infected eyes showing corneal edema and
prominent hyperintensities (leukocytic infiltrates) at 24 hours PI. The central
vertical line artifact is a Purkinje-reflection indicative of alignment with the
corneal apex, which was used to control for consistency between eyes during
image acquisition. (C) Avidin labeled mast cells (green) reside
along the cornea-sclera junction in close association with the
CD31+ limbal blood vessels (red), image was captured at
20× magnification, scale bar = 100 μm. (D)
Confocal images of peri-corneal mast cells at 20× magnification in
healthy, scratch control, and HSV-1 infected corneas at 48 hours PI. White
arrows point to degranulated mast cells to highlight the widespread
degranulation observed following HSV-1 infection; scale bar = 100
μm.
