Abstract: A mutation in VRC01, a broadly neutralizing, HIV-1-specific antibody, confers enhanced binding to the neonatal Fc receptor, increasing the antibody half-life in the serum and localization in mucosal tissues, where it provides superior protection against rectal simian HIV-1 infection in macaques.
