Anti-phospholipid human monoclonal antibodies inhibit CCR5-tropic HIV-1 and induce beta-chemokines.
(J Exp Med, 2010-04-12)Traditional antibody-mediated neutralization of HIV-1 infection is thought to result from the binding of antibodies to virions, thus preventing virus entry. However, antibodies that broadly neutralize HIV-1 are rare and ... -
Association of HIV-1 Envelope-Specific Breast Milk IgA Responses with Reduced Risk of Postnatal Mother-to-Child Transmission of HIV-1.
(J Virol, 2015-10)UNLABELLED: Infants born to HIV-1-infected mothers in resource-limited areas where replacement feeding is unsafe and impractical are repeatedly exposed to HIV-1 throughout breastfeeding. Despite this, the majority of infants ... -
HIV-specific functional antibody responses in breast milk mirror those in plasma and are primarily mediated by IgG antibodies.
(J Virol, 2011-09)Despite months of mucosal virus exposure, the majority of breastfed infants born to HIV-infected mothers do not become infected, raising the possibility that immune factors in milk inhibit mucosal transmission of HIV. HIV ... -
Identification of autoantigens recognized by the 2F5 and 4E10 broadly neutralizing HIV-1 antibodies.
(J Exp Med, 2013-02-11)Many human monoclonal antibodies that neutralize multiple clades of HIV-1 are polyreactive and bind avidly to mammalian autoantigens. Indeed, the generation of neutralizing antibodies to the 2F5 and 4E10 epitopes of HIV-1 ... -
Immunological and virological mechanisms of vaccine-mediated protection against SIV and HIV.
(Nature, 2014-01-23)A major challenge for the development of a highly effective AIDS vaccine is the identification of mechanisms of protective immunity. To address this question, we used a nonhuman primate challenge model with simian ... -
Origin and evolution of HIV-1 in breast milk determined by single-genome amplification and sequencing.
(J Virol, 2011-03)HIV transmission via breastfeeding accounts for a considerable proportion of infant HIV acquisition. However, the origin and evolution of the virus population in breast milk, the likely reservoir of transmitted virus variants, ... -
Postnatally-transmitted HIV-1 Envelope variants have similar neutralization-sensitivity and function to that of nontransmitted breast milk variants.
(Retrovirology, 2013-01-10)BACKGROUND: Breastfeeding is a leading cause of infant HIV-1 infection in the developing world, yet only a minority of infants exposed to HIV-1 via breastfeeding become infected. As a genetic bottleneck severely restricts ... -
Similar T-cell immune responses induced by group M consensus env immunogens with wild-type or minimum consensus variable regions.
(AIDS Res Hum Retroviruses, 2010-05)Consensus HIV-1 genes can decrease the genetic distances between candidate immunogens and field virus strains. To ensure the functionality and optimal presentation of immunologic epitopes, we generated two group-M consensus ...
