The molecular structure of human antibodies specific for the human immunodeficiency virus.

The molecular structure of human antibodies that are specific for human immunodeficiency virus-1 (HIV-1) are of increasing interest as AIDS research progresses toward passive immunotherapeutics in the maintenance and prevention of infection. In recent years a number of human, HIV-specific hybridomas and EBV-transformed B cell lines, as well as a combinatorial library, have been developed and characterized at the molecular level. These sources have provided valuable information on the immunoglobulin heavy- and light-chain variable-region gene usage and the extent and appearance of somatic mutation in a disease where the immune system is under constant stimulation over a long period of time. In this article we review the current data available on the molecular structure of these antibodies.
