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

This study uses non-invasive fecal samples and chromosome 21 target capture sequencing to analyze bonobo population structure, identifying three subpopulations and river barriers influencing genetic differentiation.

This study shows that vaccination of macaques with an Env-ferritin nanoparticle rapidly elicits V2-apex broadly neutralizing antibodies with immunogenetic features that may be applicable to humans.

The paper identifies frequent and genetically diverse CDRH3 topologies in the human antibody repertoire that can be targeted by vaccination to elicit broadly neutralizing antibodies.

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 identifies shared maturation pathways of V3-glycan broadly neutralizing antibody lineages in humans and rhesus macaques, revealing convergent mutations and evolution patterns.

This paper describes a user-managed 100 keV electron microscope setup for structural virology, enabling high-quality cryo-EM data collection and analysis within a laboratory setting.

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

This study shows a novel two-step mechanism for inducing broadly neutralizing HIV antibodies in macaques using a modified SHIV, informing vaccine design.

This study shows that the HIV-1 envelope cytoplasmic tail downregulates CD4, protecting infected cells from ADCC by preventing Env conformational changes that expose epitopes recognized by CD4i antibodies and plasma from PLWH.

This paper introduces WIN332, an engineered immunogen that elicits N332-glycan-independent V3-glycan antibodies in nonhuman primates after a single immunization.

This study isolates and characterizes V2 apex-directed neutralizing antibodies from SHIV-infected macaques, revealing structural and genetic features that enable broad neutralization.

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.

This study shows that transient glycan deletions in SHIVs can induce CD4-binding site broadly neutralizing antibodies in macaques, offering a model for HIV vaccine design.

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

This study shows that sequential immunization of macaques with engineered and native-like HIV-1 Env trimers elicits antibodies that neutralize by targeting non-closed Env conformations.

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

This paper combines three CD4-induced antibodies with a CD4-mimetic to achieve potent ADCC activity against HIV-1-infected cells.

This study evaluates DNA quality from urine and other sources in wild chimpanzees, finding urine provides higher DNA quantity and quality for genomic analysis.
