摘要: 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.

摘要: The present invention provides novel scaffolded HIV-1 vaccine immunogens. Some of the scaffolded immunogens contain a soluble gp140 trimer linked to the N-terminus of the nanoparticle subunit and a T-helper epitope that is fused via a short peptide spacer to the C-terminus of the nanoparticle subunit. Some other immunogens of the invention contain a soluble gp140 trimer protein that is linked to a stable nanoparticle via a short peptide spacer that is a T-helper epitope. Some of the scaffolded immunogens contain a gp140 trimer immunogen presented on a nanoparticle platform formed with I3-01 protein, E2p, or variants of protein 1VLW. Also provided in the invention are nucleic acids that encode the various vaccine immunogens described herein, and expression vectors and host cells harboring the nucleic acids. The invention further provides methods of using the scaffolded HIV-1 vaccine immunogens for preventing or treating HIV infections.

摘要: The present invention provides methods for producing scaffolded (e.g., nanoparticle presented) or non-scaffolded vaccines that are based on viral immunogenic proteins with a glycan shielded (e.g., HIV-1 Env). The vaccines thus generated demonstrate enhanced immunogenicity and responder frequency. The methods entail (1) enzymatic digestion of glycan chain on the surface of a viral trimer protein immunogen or a self-assembling nanoparticle vaccine displaying the viral immunogen (e.g., an HIV-1 UFO trimer), or (2) expression of a construct encoding the vaccine in an expression system lacking normal glycosylation function for human proteins. Also provided in the invention are vaccine compositions produced with the described methods. The invention further provides methods of using the vaccine compositions described herein (e.g., scaffolded or non-scaffolded HIV-1 vaccines) in various therapeutic applications, e.g., for preventing or treating viral infections.
