The Type A influenza M1 protein is enveloped by a lipid bilayer where the hemagglutinin (HA), neuraminidase (NA) and M2 proteins are embedded. While it has been believed that M1 is completely protected by the lipid membrane, we have discovered that a portion of it is in fact exposed and accessible to monoclonal antibody binding, and therefore represents a vaccine target. We have determined that it is critical to engineer the immunogen to allow the immune system to focus its response on the surface-exposed, highly conserved, M1 epitope. Once the immune system has done this, it will recall that response when re-challenged by any Type A influenza.
