Popis: Human monocytes/macrophages, which express Fc receptors for IgG are involved in human immunodeficiency virus type 1 (HIV-1) infection and pathogenesis. These receptors are known to mediate numerous immunological functions including cell-mediated killing and possibly targeting of HIV to the lysophagosome monocyte-derived macrophage (MDM) entry route for virus neutralization. To study both activities in HIV-1 infection, MDM Fc gamma RI was specifically selected using bispecific antibody (Bs-Ab) containing whole human monoclonal antibody against gp41 and the Fab' fragment of murine anti-Fc gamma RI 22.2 antibody. Bs-Ab was found to mediate potent antibody-dependent cellular cytotoxicity and virus neutralization.
