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.
