title: Conditioned immunosuppression of lipopolysaccharide-induced antibody response of orally immunized mice.
abstract: BALB/C mice previously conditioned in a paired regimen in which cycophosphamide was given in association with a novel taste in the drinking water (saccharin, SAC) subsequently received LPS (1mg/mouse) by oral gavage. Subgroups of mice were reexposed to SAC or water respectively, and anti-LPS antibody production measured 6 days later using an ELISA/ELISPOT assay. Our data show that the immune response to this T-independent antigen, administered orally, is amenable to conditioned immunosuppression in this model system.
