Almost all childhood HIV-1 is now acquired through vertical transmission. Identifying factors that affect the rate of transmission may lead to the initiation of specific preventive strategies. In this study, antibody levels against different neutralizing epitopes on the envelope glycoprotein of HIV-1 (gp120) were measured in HIV-1-infected pregnant women(More)
Host antibody response to toxin molecules is a major obstacle to the use of immunotoxins as efficacious agents in the treatment of human cancer and other diseases. In this study, a genetic form of immunotoxin has been designed which should eliminate toxin immunogenicity by replacing the toxin protein moiety with weakly immunogenic or nonimmunogenic plasmid(More)
In this study, a human CD4+ T lymphocyte line was transduced to secrete Fab fragments of a broadly neutralizing human monoclonal antibody F105 that reacts with the CD4-binding site of human immunodeficiency virus type 1 (HIV-1) envelope protein. In the transduced cells infected with HIV-1, the nascent Fab fragments bind intracellularly to the HIV-1 envelope(More)
