A murine model was developed which allowed study of autologous humoral and cellular immune responses (CCMI) to a Herpes Simplex Virus, type 1 (HSV-1) infection. Lethal irradiation was used to render BAlb/c mice non-responsive to T-dependent and T-independent antigens. The immune system of the irradiated animals was reconstituted with either HSV-1 primed or non-immune syngeneic spleen cells and the mice were infected with HSV-1 in the rear footpad. Whereas unirradiated mice showed no symptoms of infection, X-irradiated animals followed a clinical course of lesions, monoplegia, paraplegia and death by day 9. Irradiated animals reconstituted with HSV-1 primed spleen cells recovered from the HSV-1 infection following a transient appearance of lesions. HSV-1 infected, immunodeficient animals reconstituted with unprimed spleen cells survived for 12 days post infection. Removal of T cells from the reconstituting cell population prevented both the recovery mediated by the primed cells and the partial protection mediated by the unprimed cells, however, removal of B cells had no effect on the course of infection. The role of autologous anti-HSV-1 antibody in protection from an HSV-1 infection was assessed HSV-1 primed mice treated with cyclophosphamide to abolish their cell mediated immunity.
