AB Approximately 70% of human immunodeficiency virus (HIV)-1-infected
pregnant women do not transmit HIV to their offsprings. The
identification of factors involved in maternal-child transmission of HIV
is important for the design and implementation of therapeutic and
prevention strategies. Recently we have developed a modified peripheral
mononuclear cell (PBMC) culture system for in vitro antibody production
(IVAP) by which we can distinguish serum-derived cytophilic anti-HIV-1
antibody from de novo synthesized antibody. In this study, we analyzed
the presence of antibodies directed to HIV-1 gp160, gp120, gp41, and V3
loop synthetic peptides (C51, C53, and C57 from MN and IIIB strains)
utilizing the grid-blot method in PBMC cultures of 52 mother-child
pairs. Among the mothers (39 nontransmitters and 13 transmitters),
presence of serum-derived cytophilic antibodies or de novo synthesized
HIV V3 loop peptide-specific antibodies did not correlate with vertical
transmission. However, PBMC-associated, cytophilic antibodies of
maternal origin reactive with C51, C53, and C57 from MN and IIIB strains
were identified in cultures of uninfected infants, but not in infected
infants. These observations suggest that cytophilic antibodies of
maternal origin directed to HIV-1 V3 loop peptides which are bound to
infant cells might play a role in preventing vertical transmission.
