Abstract

Antibody to the human immunodeficiency virus (HIV)-l principal neutralizing determinant (V3 loop) was measured by peptide enzyme-linked immunosorbent assay (ELISA) in cerebrospinal fluid (CSF) and paired serum samples of 21 HIV-seropositive patients. These patients had normal neurologic examinations and were without neurologic symptoms. Peptide ELISA demonstrated intrathecal antibody synthesis against the V3 loop of HIVMN, the V3 loop of HIVNY5, the V3 loop of HIVLAI, and the entire recombinant HIV-1MN gpl20 in 21 of 21, 10 of 21, one of 21, and 12 of 21 patients, respectively. Biospecific interaction analysis (BIAcore), which requires only small amounts of CSF, was also used to detect anti-V3 CSF antibody. Fine mapping of linear epitopes within the V3 region was successful in three of five patients by Geysen PIN (PEPSCAN) ELISA and discordance between epitope specificity of CSF and serum antibody was found. While detection of CSF antibody against the V3 loop of HIVMN by peptide ELISA has been recently reported, we add to this finding using the peptide ELISA, PEPSCAN and BIAcore methodologies as well as measuring intrathecal antibody synthesis against V3 loops from HIV strains. Application of these techniques to future studies of anti-V3 antibody in CSF from persons receiving anti-HIV-1 immunizations may provide insight into the immunoregulation of the virus in the nervous system.
