- AB An acute graft versus host disease (GvHD) murine model was developed to
- study the pathogenic and protective mechanisms against viruses that
- replicate in cells of the human immune system. The model allowed
- efficient replication of lymphotropic, macrophage and amphitropic
- strains of human immunodeficiency virus type 1 (HIV-1) and measles virus
- (MV). Cytopathic lymphotropic strains of HIV-1 and a wild-type MV strain
- replicated in a 'burst'-like manner, whereas a non-cytopathic
- lymphotropic HIV-1 strain and all macrophage-tropic HIV-1 strains caused
- persistent infection of the graft. The replication kinetics of infection
- with these viruses were highly reproducible and were very similar to
- those observed in natural infection of humans. Infection with these
- viruses, with the exception of HIV-1SF2, led to a significant delay and
- abrogation of the GvHD, indicating a direct immunosuppressive effect.
- Interestingly, infection with the lymphotropic HIV-1SF2 strain was
- rapidly and spontaneously abrogated. The model was also shown to be
- suitable for the evaluation of passive immunization strategies.
- Administration of a combination of antibodies against the HIV-1 V3 loop
- and the HIV-1 CD4 binding sites prevented subsequent infection with
- HIV-1IIIB. In contrast, administration of CD4 binding site specific
- human monoclonal antibody at a concentration that would neutralize the
- virus in vitro enhanced in vivo infection with HIV-1IIIB. The model also
- allowed evaluation of in vivo immunization studies. Immunization with a
- live attenuated measles vaccine resulted in protection from a wild-type
- MV challenge, whereas immunization with a subunit candidate vaccine
- appeared to give partial protection.
