![عکس صفحه اول مقاله: Binding of inferred germline precursors of broadly neutralizing HIV-1 antibodies to native-like envelope trimers Binding of inferred germline precursors of broadly neutralizing HIV-1 antibodies to native-like envelope trimers](/preview/png/6139403.png)
- HIV-1 envelope glycoproteins (Env) usually do not interact with the inferred germline precursors of bNAbs.
- Some inferred germline precursors of bNAbs bind to soluble native-like SOSIP.664 Env trimers.
- SOSIP.664 trimers present a platform to target germline precursors of bNAbs.
HIV-1 envelope glycoproteins (Env) and Env-based immunogens usually do not interact efficiently with the inferred germline precursors of known broadly neutralizing antibodies (bNAbs). This deficiency may be one reason why Env and Env-based immunogens are not efficient at inducing bNAbs. We evaluated the binding of 15 inferred germline precursors of bNAbs directed to different epitope clusters to three soluble native-like SOSIP.664 Env trimers. We found that native-like SOSIP.664 trimers bind to some inferred germline precursors of bNAbs, particularly ones involving the V1/V2 loops at the apex of the trimer. The data imply that native-like SOSIP.664 trimers will be an appropriate platform for structure-guided design improvements intended to create immunogens able to target the germline precursors of bNAbs.
