AB Human immunodeficiency virus type 1 (HIV-1) has a complex life cycle,
which has made it a difficult target for conventional therapeutic
modalities. A single-chain antibody moiety, directed against the HIV-1
regulatory protein Rev, which rescues unspliced viral RNA from the
nucleus of infected cells, has now been developed. This anti-Rev
single-chain construct (SFv) consists of both light and heavy chain
variable regions of anti-Rev monoclonal antibody, which, when expressed
intracellularly within human cells, potently inhibits HIV-1 replication.
This intracellular SFv molecule is demonstrated to specifically
antagonize Rev function. Thus, intracellular SFv expression, against a
retroviral regulatory protein, may be useful as a gene therapeutic
approach to combat HIV-1 infections.
