AB We have tested a novel strategy of intracellular immunization to block
human immunodeficiency virus (HIV) infection. The expression of a
specific antibody within a cell was achieved by transduction of genes
that encode for immunoglobulin chains with specificity to viral reverse
transcriptase. We demonstrated that inhibition of this enzyme makes
cells resistant to HIV infection by blocking an early stage of viral
replication. If high efficiency transduction with a stable vector into
lymphohaematopoietic stem cells or mature lymphocytes can be achieved,
gene transfer-mediated intracellular immunization might be a feasible
treatment strategy in AIDS.
