The paper shows that early clonal dominance in B-cell precursors after vaccination predicts the breadth of HIV-neutralizing antibodies in rhesus macaques.

Epitope-focused S2 stem-helix nanoparticle immunogens elicit protective broadly neutralizing antibodies against diverse betacoronaviruses in non-human primates, establishing a framework for pan-betacoronavirus vaccines.

This study shows that a germline-targeting HIV immunogen induces cross-neutralizing antibodies in outbred macaques by priming V2-apex bnAb B cell precursors.

The paper designs native-like HIV Env single-chain trimers (SCTs) that are stable, immunogenic, and compatible with vaccine delivery methods.

This study shows that a single immunization with a germline-targeting trimer can induce broad HIV-1 neutralizing antibodies in a rhesus macaque bnAb mouse model.

The paper identifies B cell priming as the main obstacle to developing HIV-1 V2 apex broadly neutralizing antibodies in SHIV-infected macaques.

This paper introduces a method to map HIV-1 neutralizing epitopes using Cys labeling, neutralization assays, and deep sequencing, validated against known structural epitopes.
