TI Inter- and intraclade neutralization of human immunodeficiency virus
type 1: genetic clades do not correspond to neutralization serotypes but

AB We have studied genetic variation among clades A through E of human
immunodeficiency virus type 1 (HIV-1) at the levels of antibody binding
to gp120 molecules and virus neutralization. We are unable to identify
neutralization serotypes that correspond to the genetic clades. Instead,
we observe that inter- and intraclade neutralization of primary isolates
by HIV-1-positive sera is generally weak and sporadic; some sera show a
reasonable degree of neutralization breadth and potency whereas others
are relatively sensitive to neutralization, but no consistent pattern
was found. However, a few sera were able to neutralize across clades
with significant potency, an observation which may have implications for
the feasibility of a broadly effective HIV-1 vaccine involving humoral
immunity. Serological assays measuring anti-gp120 antibody binding also
failed to identify serotypes that correspond precisely to the genetic
clades, but some indications of clade-specific binding were observed,
notably with sera from clades B and E. A representative protein for each
clade (A through E) was selected on the basis of its specificity,
defined as high seroreactivity with sera from individuals infected with
virus of that clade and lower reactivity with sera from individuals
infected with viruses from other clades. The seroreactivity patterns
against these five proteins could be used to predict the genotype of the
infecting virus with moderate success.
