Title: Nucleic acids encoding HIV-1 GP140 immunogens comprising modified NHR1 regions that stabilize pre-fusion conformations

Patent ·
OSTI ID:1892576

The present invention provides HIV-1 vaccine immunogens. Some of the immunogens contain a soluble gp140-derived protein that harbors a modified N-terminus of the HR1 region in gp41. Some of the immunogens contain an HIV-1 Env-derived trimer protein that is presented on a nanoparticle platform. The invention also provides methods of using the HIV-1 vaccine immunogens for eliciting an immune response or treating HIV infections.
