Passive neutralizing antibody controls SHIV viremia and enhances B cell responses in infant macaques

Maternal HIV-1-specific antibodies are efficiently transferred to newborns; their role in disease control is unknown. We administered non-sterilizing levels of neutralizing IgG, including the human neutralizing monoclonal IgG1b12, to six newborn macaques before oral challenge with SHIV(SF612P3). All...

Sumario:Maternal HIV-1-specific antibodies are efficiently transferred to newborns; their role in disease control is unknown. We administered non-sterilizing levels of neutralizing IgG, including the human neutralizing monoclonal IgG1b12, to six newborn macaques before oral challenge with SHIV(SF612P3). All rapidly developed neutralizing antibodies and had significantly reduced plasma viremia for 6 months. These studies support the use of neutralizing antibodies in enhancing B cell responses and viral control in perinatal settings.
