Immunogenic Peptides Against Influenza Virus

Immunogenic Peptides Against Influenza Virus

The invention described herein are peptides and polypeptides derived from the HA, NA, PB2, PB1, PA, M1, M2, NP, NS1, and NS2 proteins of influenza virus that elicit immunogenic responses; particularly neutralizing antibodies, against human and avian influenza strains H1N1, H3N2, H5N1 and H7N7. Materials in the form of immunogenic compositions including these peptides and polypeptides can also be in-licensed along with the patent rights. Pharmaceutical compositions including these peptides and polypeptides with or without adjuvants are within the scope of the invention. The inventors are currently investigating the vaccine potential of specific peptides and polypeptides.

Potential Commercial Applications:

  • Vaccines against influenza virus infection;
  • Diagnostics for the detection of influenza virus infection; and
  • Generation of influenza virus specific antibodies.

Competitive Advantages:

  • Peptides can be expressed in a number of different expression systems; and
  • Peptides were identified based on the specificity of antibodies derived from human and avian influenza virus infected individuals.
