SARS-CoV-2 Omicron XBB lineage spike structures, conformations, antigenicity, and receptor recognition

The paper determines cryo-EM structures of SARS-CoV-2 XBB lineage spike proteins, revealing structural changes that enhance immune evasion and receptor binding.

Conformational flexibility of HIV-1 envelope glycoproteins modulates transmitted / founder sensitivity to broadly neutralizing antibodies

This paper shows that some HIV-1 transmitted/founder Envs are incompletely closed, making them sensitive to antibodies targeting open conformations, and highlights the importance of Env conformational flexibility for bnAb neutralization.

Vaccine induction of CD4-mimicking broadly neutralizing antibody precursors in macaques

This study shows that vaccinating macaques with a CD4bs-targeting immunogen elicits neutralizing bnAb precursors with structural features of CD4-mimicking antibodies.

Structure-based stabilization of SOSIP Env enhances recombinant ectodomain durability and yield

This paper introduces a proline-stabilization strategy (2P) to enhance the durability and yield of recombinant HIV-1 Env trimers without altering their antigenic or conformational properties.

Cryo-EM structures of SARS-CoV-2 Omicron BA.2 spike

This study determines cryo-EM structures of SARS-CoV-2 Omicron BA.2 spike and compares them to BA.1, revealing structural changes and immune evasion mechanisms.

Structural diversity of the SARS-CoV-2 Omicron spike

The paper compares cryo-EM structures of SARS-CoV-2 Omicron and Delta spikes to analyze conformational changes affecting immune evasion and transmissibility.

Sequence and functional characterization of a public HIV-specific antibody clonotype

The paper characterizes a public HIV-specific antibody clonotype from three individuals, showing that antigen specificity is modulated by VH germline genes and that non-native heavy-light chain pairings maintain consistent antigen recognition.

Effect of natural mutations of SARS-CoV-2 on spike structure, conformation and antigenicity

This study examines how mutations in SARS-CoV-2 spike protein affect its structure, conformation, and antigenicity across variants from different origins.

The functions of SARS-CoV-2 neutralizing and infection-enhancing antibodies in vitro and in mice and nonhuman primates

This study examines SARS-CoV-2 neutralizing and infection-enhancing antibodies, showing in vitro enhancement does not always lead to in vivo disease enhancement, but can cause increased lung inflammation in monkeys.

Cross-reactive coronavirus antibodies with diverse epitope specificities and extra-neutralization functions

The paper identifies cross-reactive antibodies against multiple coronaviruses, showing they target diverse epitopes and mediate effector functions.

D614G mutation alters SARS-CoV-2 spike conformational dynamics and protease cleavage susceptibility at the S1/S2 junction

This study shows the D614G mutation in SARS-CoV-2 spike protein increases furin cleavage efficiency and alters RBD dynamics through allosteric effects.

Cold sensitivity of the SARS-CoV-2 spike ectodomain

The paper shows that the SARS-CoV-2 spike ectodomain construct 2P is cold-sensitive, and this sensitivity is resolved in a down-state stabilized spike.

A glycan cluster on the SARS-CoV-2 spike ectodomain is recognized by Fab-dimerized glycan-reactive antibodies

The paper shows that HIV-1 broadly neutralizing antibodies recognize a glycan cluster on the SARS-CoV-2 spike protein, revealing a potential target for vaccine design.

Fab-dimerized glycan-reactive antibodies neutralize HIV and are prevalent in humans and rhesus macaques

The paper identifies Fab-dimerized glycan-reactive antibodies in HIV-infected macaques and HIV-naïve humans that neutralize HIV-1 and can be elicited by vaccination.

Glycans on the SARS-CoV-2 Spike Control the Receptor Binding Domain Conformation

The paper shows glycans on SARS-CoV-2 Spike influence RBD conformational states, affecting antibody neutralization and vaccine design.

Controlling the SARS-CoV-2 Spike Glycoprotein Conformation
