This research aims to uncover the primary bottlenecks in the development of broadly neutralizing antibodies (bNAbs) targeting the V2 apex during HIV infection.
Longitudinal study of 122 rhesus macaques infected with 16 different simian-human immunodeficiency viruses (SHIVs)
Analysis of Env-antibody coevolution focusing on B cell priming and bNAb development
Phylogenetic examination of antibodies and evolving Env structures
Identified V2 apex as the main target for bNAbs in SHIV-infected macaques
Found that low mutation rates in V2 apex regions inhibit effective B cell priming
Showed that efficiency of B cell priming, rather than complexity in antibody maturation, poses a significant challenge to bNAb elicitation.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Longitudinal study shows low efficiency of B cell priming in HIV-infected macaques, implying challenges for bNAb production.
