HIV-1 Env Fusion Peptide Immunogens and Their Use

    Description of Technology: Millions of people are infected with 
HIV-1 worldwide, and 2.5 to 3 million new infections have been 
estimated to occur yearly. Although effective antiretroviral therapies 
are available, millions succumb to AIDS every year, especially in Sub-
Saharan Africa, underscoring the need to develop measures to prevent 
the spread of this disease.
    HIV-1 is an enveloped virus, which hides from humoral recognition 
behind a wide array of protective mechanisms. During infection, the 
major envelope protein of HIV-1 is cleaved by host cell proteases into 
two smaller versions (gp120 and gp41). Together gp120 and gp41 make up 
the HIV-1 Env spike, which is a target for neutralizing antibodies. It 
is believed that immunization with an effective immunogen based on the 
HIV-1 Env glycoprotein can elicit a neutralizing response, which may be 
protective against HIV-1 infection.
    Researchers at the Vaccine Research Center (VRC) of the National 
Institute of Allergy and Infectious Diseases used knowledge from the 
crystal structure of an HIV-1 neutralizing antibody, VRC34.01, in 
complex with its epitope on the HIV-1 Env trimer, to develop novel 
immunogens. HIV-1 uses a fusion peptide, located at the N-terminus of 
the gp41 subunit, to fuse with a target cell to infect the cell. The 
crystal structure revealed the epitope recognized by VRC34.01 to be 
composed primarily of the exposed 8 residues of the fusion peptide at 
the N-terminus of the gp41 subunit. Researchers designed fusion peptide 
immunogens that were comprised of the exposed residues of the fusion 
peptide coupled to highly immunogenic carrier proteins to focus the 
immune response to this conserved site of vulnerability. The fusion 
peptide can be displayed on scaffold proteins and--when coupled to HIV-
1 Env trimer boosts--has the potential to elicit antibodies capable of 
neutralizing diverse HIV-1 strains in mice, guinea pigs and rhesus 
macaques, and might therefore serve as the basis for an effective HIV 
vaccine.
    This technology is available for licensing for commercial 
development in accordance with 35 U.S.C. 209 and 37 CFR part 404.
