    The neonatal Fc receptor (FcRn) enhances human immunodeficiency virus type 1 (HIV-1) transcytosis across epithelial cells

    Gupta, Sandeep ; Gach, Johannes S. ; Becerra, Juan C. ; Phan, Tran B. ; Pudney, Jeffrey ; Moldoveanu, Zina ; Joseph, Sarah B. ; Landucci, Gary ; Supnet, Medalyn Jude ; Ping, Li-Hua ; Corti, Davide ; Moldt, Brian ; Hel, Zdenek ; Lanzavecchia, Antonio ; Ruprecht, Ruth M. ; Burton, Dennis R. ; Mestecky, Jiri ; Anderson, Deborah J. ; Forthal, Donald N.

    The mechanisms by which human immunodeficiency virus type 1 (HIV-1) crosses mucosal surfaces to establish infection are unknown. Acidic genital secretions of HIV-1-infected women contain HIV-1 likely coated by antibody. We found that the combination of acidic pH and Env- specific IgG, including that from cervicovaginal and seminal fluids of HIV-1-infected individuals, augmented transcytosis...

    An anti-HIV-1 V3 loop antibody fully protects cross-clade and elicits T-cell immunity in macaques mucosally challenged with an R5 clade C SHIV

    Neutralizing antibodies have been shown to protect macaques against SHIV challenge. However, genetically diverse HIV-1 clades have evolved, and a key question left unanswered is whether neutralizing antibodies can confer cross-clade protection in vivo. The novel human monoclonal antibody HGN194 was isolated from an individual infected with an HIV-1 clade AG recombinant circulating recombinant...
