Molecular basis for antiviral activity of pediatric neutralizing antibodies targeting SARS-CoV-2 Spike receptor binding domain

This study identifies two potent neutralizing antibodies, EH3 and EH8, from a pediatric patient that cross-neutralize SARS-CoV-2 variants and provide in vivo protection against the Delta VOC.

HIV-1 Vpu restricts Fc-mediated effector functions in vivo

This study shows that HIV-1 Vpu reduces nnAb recognition and ADCC resistance, with nnAb Fc-effector functions dependent on Env's open conformation.

Engineered ACE2-Fc counters murine lethal SARS-CoV-2 infection through direct neutralization and Fc-effector activities

The paper develops ACE2-Fc molecules that neutralize SARS-CoV-2 and show Fc-effector activity, effectively treating lethal infection in mice.

Structural Basis and Mode of Action for Two Broadly Neutralizing Antibodies Against SARS-CoV-2 Emerging Variants of Concern

This study characterizes two SARS-CoV-2 antibodies effective against variants, showing their structural basis and mechanisms of neutralization.

Impact of temperature on the affinity of SARS-CoV-2 Spike for ACE2

This study investigates how temperature affects SARS-CoV-2 Spike protein affinity for ACE2, finding increased binding at low temperatures, which is mitigated by the N501Y mutation.

Live imaging of SARS-CoV-2 infection in mice reveals neutralizing antibodies require Fc function for optimal efficacy

This study uses live imaging to show that neutralizing antibodies against SARS-CoV-2 need both Fab and Fc functions to effectively prevent and resolve infection in mice.

A single BNT162b2 mRNA dose elicits antibodies with Fc-mediated effector functions and boost pre-existing humoral and T cell responses

This study shows a single dose of the BNT162b2 mRNA vaccine elicits strong antibody and T cell responses, including Fc-mediated effector functions, and boosts pre-existing immunity in previously infected individuals.

Longitudinal analysis of humoral immunity against SARS-CoV-2 Spike in convalescent individuals up to 8 months post-symptom onset

This study tracks humoral immune responses in convalescent individuals up to 8 months post-SARS-CoV-2 infection, showing that IgG+ memory B cells persist while plasma antibody levels decline.

High-throughput detection of antibodies targeting the SARS-CoV-2 Spike in longitudinal convalescent plasma samples

This study tracks the decline of antibodies against the full-length SARS-CoV-2 Spike in convalescent plasma over time, showing a gradual decrease correlated with RBD-specific antibodies and days post-infection.

Real-time conformational dynamics of SARS-CoV-2 spikes on virus particles

This study uses smFRET to observe real-time conformational dynamics of SARS-CoV-2 spikes on virus particles, revealing multiple states and mechanisms of neutralization by antibodies and convalescent plasma.

Interaction of human ACE2 to membrane-bound SARS-CoV-1 and SARS-CoV-2 S glycoproteins

This study compares the cooperativity of ACE2 binding to SARS-CoV-1 and SARS-CoV-2 Spike proteins, finding that SARS-CoV-2 exhibits positive cooperativity.

Cross-sectional evaluation of humoral responses against SARS-CoV-2 Spike

This study evaluates humoral responses against SARS-CoV-2 Spike in 106 infected individuals, finding persistent RBD-specific IgG and declining neutralizing activity over time.
