- AB Levels of natural antibodies (NAb) with high anti-trinitrophenyl (TNP)
- activity are increased during human immunodeficiency virus (HIV)
- infection. The aim of the present study was to examine the anti-HIV
- effect of natural anti-TNP antibodies, as well as that of their internal
- image, TNP antigen, on HIV infection in vitro. The results obtained with
- anti-TNP antibodies, as assessed by syncytia formation, were variable,
- although they demonstrated an inhibitory effect. In contrast, using RT
- activity assay plus evaluation of syncytia formation and the viral
- cytopathic effect, we found that bovine serum albumin (BSA) bearing
- different TNP groups was able to inhibit HIV infection of peripheral
- mononuclear cells and T4 cell lines without affecting cell metabolism or
- proliferation. BSA alone was devoid of activity; the antiviral effect
- depended on TNP substitution of the BSA molecule, and passage through an
- anti-TNP immunoadsorbent abolished this effect. The mechanism by which
- TNP exerts this antiviral effect is unclear. Antigenic epitopes may be
- shared by HIV and TNP, since monoclonal antibodies directed against
- various HIV proteins reacted with TNP in an enzyme immunoassay. TNP-BSA,
- however, did not bind to the CD4 receptor.
