for use for several hours that day while the upgrade is in progress. Deposits to DukeSpace
will be disabled on Monday December 11, so no new items are to be added to the repository
while the upgrade is in progress. Everything should be back to normal by the end of
day, December 12.

Co-evolution of a broadly neutralizing HIV-1 antibody and founder virus.
(Nature, 2013-04-25)Current human immunodeficiency virus-1 (HIV-1) vaccines elicit strain-specific neutralizing antibodies. However, cross-reactive neutralizing antibodies arise in approximately 20% of HIV-1-infected individuals, and details ... -
Correction: Neutralization-guided design of HIV-1 envelope trimers with high affinity for the unmutated common ancestor of CH235 lineage CD4bs broadly neutralizing antibodies.
(PLoS pathogens, 2019-12-02)[This corrects the article DOI: 10.1371/journal.ppat.1008026.]. -
Immune checkpoint modulation enhances HIV-1 antibody induction.
(Nature communications, 2020-02-19)Eliciting protective titers of HIV-1 broadly neutralizing antibodies (bnAbs) is a goal of HIV-1 vaccine development, but current vaccine strategies have yet to induce bnAbs in humans. Many bnAbs isolated from HIV-1-infected ... -
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 ... -
Initiation of HIV neutralizing B cell lineages with sequential envelope immunizations.
(Nature communications, 2017-11-23)A strategy for HIV-1 vaccine development is to define envelope (Env) evolution of broadly neutralizing antibodies (bnAbs) in infection and to recreate those events by vaccination. Here, we report host tolerance mechanisms ... -
Neutralization properties of simian immunodeficiency viruses infecting chimpanzees and gorillas.
(MBio, 2015-04-21)UNLABELLED: Broadly cross-reactive neutralizing antibodies (bNabs) represent powerful tools to combat human immunodeficiency virus type 1 (HIV-1) infection. Here, we examined whether HIV-1-specific bNabs are capable ... -
Recapitulation of HIV-1 Env-antibody coevolution in macaques leading to neutralization breadth.
(Science (New York, N.Y.), 2020-11-19)Neutralizing antibodies elicited by HIV-1 coevolve with viral envelope proteins (Env) in distinctive patterns, in some cases acquiring substantial breadth. We report that primary HIV-1 envelope proteins-when expressed by ... -
The functions of SARS-CoV-2 neutralizing and infection-enhancing antibodies in vitro and in mice and nonhuman primates.
(bioRxiv, 2021-02-18)SARS-CoV-2 neutralizing antibodies (NAbs) protect against COVID-19. A concern regarding SARS-CoV-2 antibodies is whether they mediate disease enhancement. Here, we isolated NAbs against the receptor-binding domain (RBD) ... -
Two distinct broadly neutralizing antibody specificities of different clonal lineages in a single HIV-1-infected donor: implications for vaccine design.
(J Virol, 2012-04)Plasma from a small subset of subjects chronically infected with HIV-1 shows remarkable magnitude and breadth of neutralizing activity. From one of these individuals (CH0219), we isolated two broadly neutralizing antibodies ...
