Projects:

1. Nussenzweig. Develop and simplify immunization protocols that elicit bNAbs to V3/N332 in iGL knock-in mice, (2) Adapt immunization protocols developed for V3/N332 bNAbs in knock-in mice to wild type and AlivaMab mice that carry un-rearranged human antibody loci, (3) Develop an immunization protocol to elicit IOMA-like antibodies, and (4) Determine the frequency of IOMA and V3/N332 bNAb precursors in the naïve B cell repertoire of un-infected human donors.

2. Bjorkman. Solve structures of iGL–immunogen complexes to aid in structure-based immunogen design, (2) Use structure-based design and library screening to identify Env trimers that bind V3/N332 iGLs with high affinity, (3) Use structural information to guide construction of a yeast display library to find rare variants that bind IOMA iGL, (4) Combine results to create Env trimer immunogens that bind iGLs of both bNAbs and work with Dr. Nussenzweig to evaluate double and single immunogens in mice.
