CD4 downregulation precedes Env expression and protects HIV-1-infected cells from ADCC mediated by non-neutralizing antibodies

The paper shows CD4 downregulation precedes Env expression in HIV-1-infected cells, making them resistant to non-neutralizing antibody-mediated ADCC.

Temperature-dependent Spike-ACE2 interaction of Omicron subvariants is associated with viral transmission

This study examines how temperature affects Spike-ACE2 interactions in Omicron subvariants and links these interactions to viral transmission efficiency.

A third SARS-CoV-2 mRNA vaccine dose in people receiving hemodialysis overcomes B cell defects but elicits a skewed CD4+ T cell profile

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.

Identification of a SARS-CoV-2 host metalloproteinase-dependent entry pathway differentially used by SARS-CoV-2 and variants of concern Alpha, Delta, and Omicron

This study identifies a MMP2/9-dependent entry pathway for SARS-CoV-2 and variants, showing differential usage and reduced activity in Omicron.

Temporal associations of B and T cell immunity with robust vaccine responsiveness in a 16-week interval BNT162b2 regimen

The paper examines B and T cell immunity responses to a 16-week interval BNT162b2 vaccine regimen, finding robust immune memory and functional associations between immune components.

An anti-SARS-CoV-2 non-neutralizing antibody with Fc-effector function defines a new NTD epitope and delays neuroinvasion and death in K18-hACE2 mice

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.

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.
