Challenge studies following passive immunization with neutralizing Abs suggest that an HIV vaccine could be efficacious were it able to elicit broadly neutralizing Abs (bNAbs). To better understand the requirements for activation of B cells producing bNAbs, we generated cell lines expressing bNAbs or their germline-reverted versions (gl-bNAbs) as BCRs. We(More)
A major goal of HIV research is to develop vaccines reproducibly eliciting broadly neutralizing Abs (bNAbs); however, this has proved to be challenging. One suggested explanation for this difficulty is that epitopes seen by bNAbs mimic self, leading to immune tolerance. We generated knock-in mice expressing bNAb 4E10, which recognizes the membrane proximal(More)
