Potential Benefits and Hazards of Humoral Immune Reactions against HTLV-III.
Abstract
Monoclonal murine IgG antibodies against Gp120 from HIV-1 were found to induce significant enhancement of HIV-1 replication in vitro when used at low antibody concentrations. This enhancement was dependent on the presence of FcR:s for IgG and was completely blocked by anti-CD4 monoclonal antibodies. HIV-1 seropositive individuals at a low frequency do produce antibodies reactive with Gp12O and 'mimicking' CD4 molecules as evidenced by their reactivity with certain CD4 monoclonal antibodies. It was, however, not possible to show that such 'mimicking' antibodies were especially efficient in neutralizing, nor was presence of such antibodies linked to a particular clinical progression behaviour. Presence of antibodies to peptides covering the respective cysteins in the V3 loop of a particular HIV-1 isolate were found using two Italian cohorts to be positively linked to a reduced rate of transmission of virus from mother to child.
