Abstract
The Fab' fragment of a monoclonal antibody (mAb) to CD3 and the F(ab')2 fragment of a mAb to human immunodeficiency virus 1 (HIV-1) gp41 were combined to generate a bifunctional antibody (BFA). The mAb to gp41 (IV1-4G6) has previously been shown to react with a number of HIV-1 strains and T-lymphoblastoid cells (TLBC) armed with the BFA (BFA-TLBC) effectively inhibited HIV-1 in primarily cultured lymphoblasts infected with the clinically isolated virus which was reactive to the mAb. Although BFA-TLBC could not cause cytolysis of 51Cr-labeled latently infected cells (OM-10.1) in 6 hr incubation, cocultivation of OM-10.1 cells with BFA-TLBC for 3 days or more eliminated the latently infected cells making the cells susceptible to BFA-TLBC. Therefore, BFA-TLBC may be beneficial for HIV-infected patients in eradicating latently infected cells which can not be eliminated even with highly active antiretroviral therapy (HAART).
