title: Antibody-dependent cellular cytotoxicity against cells infected with herpes simplex virus type 1 in Igh-1 disparate congenic mice.
abstract: The mouse Igh-1 locus on chromosome 12 influences herpetic stromal keratitis (HSK) patterns following corneal challenge with herpes simplex virus type 1 (HSV-1). Both cellular and humoral immune mechanisms appear to be important in modulating responses to HSV-1 infections, but the role of antibody-dependent cellular cytotoxicity (ADCC) is unclear. We studied the effector-cell function and antibody in an ADCC assay in Igh-1-disparate mice. Splenocytes from both HSK-susceptible C.AL-20 (Igh-1d) and HSK-resistant C.B-17 (Igh-1b) mice mediated equal amounts of ADCC to HSV-infected cell targets using monoclonal antibodies against HSV-1 glycoprotein D. Natural killer cell activity was significantly greater in C.AL-20 than in C.B-17 splenocytes. IgG2a was less efficient than both IgG1 and IgG2b in mediating ADCC to HSV-1-infected cell targets. The Igh-1 phenotype of the antibody source had no influence on ADCC activity. Our results suggest that the susceptibility of HSK observed in these Igh-1-disparate congenics cannot be explained by qualitative differences in the ADCC activity of effector cells and antibody produced in response to HSV-1 infection.
