title: The demyelinating effect of corneal HSV infections in normal and nude (athymic) mice.
abstract: Nude (athymic) mice and their immune competent Balb/c litter mates were infected with herpes simplex virus (HSV) type I on the scarified cornea. Seven to eight days after infection the trigeminal root entry zone was examined by light and electron microscopy. The immune competent Balb/c litter mates demonstrated marked central nervous system (CNS) demyelination when compared to the T cell-deficient animals who showed mild edematous change and minimal CNS demyelination ultrastructurally 7 days after infection. Viral titers were similar in both groups at this time. These studies further substantiate a role for the cell-mediated immune system in the CNS demyelination 1 week after corneal infection with HSV.
