title: Functional consequences of macrophage infection by human immunodeficiency virus: bispecific antibody targeting of HIV-1-infected cells to Fc gamma RI expressing effector cells.
abstract: Human monocytes/macrophages play a major role in pathogenesis of human immunodeficiency virus (HIV) infection. These cells have been suspected of acting as a reservoir for the virus and are important in viral dissemination and persistence in infected individual. Furthermore, several biologic and clinical features indicate that monocytes/macrophages from HIV-1-seropositive patients have characteristics of an activation status, including the ability to secrete high levels of cytokines. Dysregulation of the cytokine network may influence the level and the consequences of viral replication in infected monocytes/macrophages. Therefore, the development of virus-specific agents that may interfere with viral replication could help to slow down the fatal course of HIV infection. In this article, we try to further quantify the early and late kinetic patterns of the cytokine network during HIV-1 macrophage infection and report the biologic effects of virus-specific bispecific antibody (MDX-240) in HIV-1 macrophage infection.
