CD4+V beta 8+ T cells mediate herpes stromal keratitis.
T lymphocytes are critical in mediating herpes simplex stromal keratitis (HSK). Using immunohistologic methods, we studied the T cell subsets and the T cell receptor variable region (TCR V beta) repertoire of T cells in the eye after corneal infection with HSV (KOS strain). We investigated the possibility that there might be differential V beta preferential usage in HSK resistant and susceptible BALB/c congenic mice that differ only in a small region associated with the Igh-1 gene locus. The inflamed corneas of HSK susceptible C.AL-20 mice were mainly infiltrated by CD4+ cells and by V beta 8 expressing cells. Such T cells were not seen in the corneas of resistant C.B-17 mice. Our results indicate that CD4+V beta 8+ cells are involved in mediating HSV-1 stromal keratitis.
