Abstract
Embodiments of immunogens based on the HIV-1 Env fusion peptide and methods of their use and production are disclosed. Nucleic acid molecules encoding the immunogens are also provided. In several embodiments, the immunogens can be used to generate an immune response to HIV-1 Env in a subject, for example, to treat or prevent an HIV-1 infection in the subject.
Claims20
An immunogen, comprising a human immunodeficiency virus type 1 (HIV-1) Env fusion peptide conjugated to a carrier protein by a heterologous linker, wherein:
- the HIV-1 Env fusion peptide consists of the amino acid sequence of AVGIGAV (residues 1-7 of SEQ ID NO:
- 1) or AVGIGAL (residues 1-7 of SEQ ID NO:
- 6);
- and
- the immunogen elicits a neutralizing immune response to HIV-1 in a subject.
