Abstract: Provided are human antibodies that specifically bind to HBV Pre-S1 domain ligand and inhibit HBV or HDV infection, antibodies binding to a set of amino acid residues that are critical for viral receptor engagement, and uses of these antibodies to prevent, or treat or diagnose HBV or HDV infection.
Abstract: The present application generally relates to the development of live attenuated Pneumoviridae strains suitable for use as a vaccine. Particularly, human metapneumovirus (hMPV) ?M2-2 strains (rhMPV-E30M31 and rhMPV-E40L42D44) containing point mutations in a PDZ motif of M2-2, which results in a strain that is both attenuated and immunogenic and, notably, maintains the function of F and G proteins. These live attenuated hMPV strains should be suitable for use in a vaccine capable of providing protection against respiratory infection elicited by hMPV. Additionally, human respiratory syncytial virus (hRSV) strains containing point mutations in a PDZ motif of M2-2 should also be suitable for use as a vaccine capable of providing protection against respiratory infection elicited by hRSV. These Pneumoviridae strains should be useful in vaccines for use in humans and animals, e.g., companion animals and livestock, in treating or providing immunoprotection against respiratory infections.
