Impaired Fas-Fas Ligand Interactions Result in Greater Recurrent Herpetic Stromal Keratitis in Mice

Figure 3

Similar patterns of disease were seen in C57BL/6 (B6) mice carrying the gld and lpr mutations following UV-B reactivation. Eyes of B6 wild-type (), B6-lpr (), and B6-gld () mice were infected with 106 pfu of HSV-1, McKrae strain. Six weeks following infection mice were irradiated with UV-B to reactivate the latent infection. Corneal opacity was measured and compared between these strains of mice. Significant virus-induced corneal opacity was observed for B6-gld (–0.001) at days 14–42 when compared to B6 controls. B6-lpr mice displayed significantly more opacity than did B6 controls at days 21 and 28 (–0.01).
