Cooperativity Enables Non-neutralizing Antibodies to Neutralize Ebolavirus [PDF]

Cell Reports, 2017
Summary: Drug combinations are synergistic when their combined efficacy exceeds the sum of the individual actions, but they rarely include ineffective drugs that become effective only in combination. We identified several “enabling pairs” of neutralizing

A gp41 MPER-specific llama VHH requires a hydrophobic CDR3 for neutralization but not for antigen recognition [PDF]

, 2013
The membrane proximal external region (MPER) of the HIV-1 glycoprotein gp41 is targeted by the broadly neutralizing antibodies 2F5 and 4E10. To date, no immunization regimen in animals or humans has produced HIV-1 neutralizing MPER-specific antibodies ...

Engineering SARS-CoV-2 neutralizing antibodies for increased potency and reduced viral escape pathways

iScience, 2022
Summary: The rapid spread of SARS-CoV-2 variants poses a constant threat of escape from monoclonal antibody and vaccine countermeasures. Mutations in the ACE2 receptor binding site on the surface S protein have been shown to disrupt antibody binding and ...

Molecular insights into antibody-mediated protection against the prototypic simian immunodeficiency virus

Nature Communications, 2022
SIVmac239 infection of macaques is a favored model of human HIV infection, but antibody-mediated protection for SIVmac239 is insufficiently understood.

The diversity of the glycan shield of sarbecoviruses related to SARS-CoV-2

Cell Reports, 2023
Summary: Animal reservoirs of sarbecoviruses represent a significant risk of emergent pandemics, as evidenced by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic.

Highly mutated antibodies capable of neutralizing N276 glycan-deficient HIV after a single immunization with an Env trimer

Cell Reports, 2022
Summary: Elicitation of HIV broadly neutralizing antibodies (bnAbs) is challenging because unmutated bnAb precursors are rare and seldom bind HIV envelope glycoprotein (Env) trimers.

Kinetics of the neutralizing antibody response to respiratory syncytial virus infections in a birth cohort [PDF]

, 2013
The kinetics of respiratory syncytial virus (RSV) neutralizing antibodies following birth, primary and secondary infections are poorly defined. The aims of the study were to measure and compare neutralizing antibody responses at different time points in ...

Cleavage-Independent HIV-1 Env Trimers Engineered as Soluble Native Spike Mimetics for Vaccine Design

Cell Reports, 2015
Viral glycoproteins mediate entry by pH-activated or receptor-engaged activation and exist in metastable pre-fusogenic states that may be stabilized by directed rational design. As recently reported, the conformationally fixed HIV-1 envelope glycoprotein

Holes in the Glycan Shield of the Native HIV Envelope Are a Target of Trimer-Elicited Neutralizing Antibodies

Cell Reports, 2016
A major advance in the search for an HIV vaccine has been the development of a near-native Envelope trimer (BG505 SOSIP.664) that can induce robust autologous Tier 2 neutralization.
