Abrégé
Provided herein are hantivirus antibodies. These hantivirus antibodies bind to the Gn and/or Gc subunits of a hantavirus glycoprotein and have broad neutralizing activity against an epitope of different hantavirus species. Such antibodies are used in methods of inducing an immune response and methods of inhibiting hantavirus infection. Additionally provided are methods of treating an infectious disease using such antibodies.
Provided are antibodies or antigen binding polypeptides characterized by the ability to neutralize respiratory syncytial virus (RSV). Specifically, the antibodies or antigen binding polypeptides are characterized by high affinity binding to RSV fusion glycoprotein (RSVF). Further provided are methods for their identification, isolation, generation, preparation, and use, as well as the heavy chain and light chain sequences of the antibodies provided.
Anti-CCHFV antibodies with neutralizing potency and protective efficacy against CCHFV are provided, as well as methods for their identification, isolation, generation, and methods for their preparation and use are provided.
Non-hormonal contraception compositions and methods for contraception are provided. One embodiment provides an antibody or an antigen binding fragment thereof that specifically binds to one or more sperm antigens and inhibits the ability of antibody-bound sperm to fertilize an egg. Typically, the antibody is a monoclonal antibody, for example a human or humanized monoclonal antibody. In one embodiment, the antibody or antigen binding fragment thereof specifically binds to CD52g expressed on vertebrate, for example human, sperm cells and inhibits, blocks, or reduces the ability of the antibody-bound sperm to fertilize an egg. In one embodiment the antibody contains a membrane anchor. The membrane anchor can contain transmembrane domains, glycosylphosphatidylinositol anchors, or myristoylation motifs.

Antibody variants originating from the monoclonal antibody 13C6, and wherein the N-glycosylation site within the constant region of the heavy chain contains a glycan that is either wild-type or largely devoid of fucose residues, will bind Ebola virus glycoprotein and provide surprising efficacy in treating animals or humans infected with Ebola virus when used in combination with one or more additional anti-Ebola mAbs. Such antibody cocktails are vastly superior to other known monoclonal antibodies or monoclonal antibody combinations in treating animals and humans infected with the Ebola virus.
This disclosure provides a method for preventing, treating, or managing a filovirus infection in a subject, where the method includes administering to a subject in need thereof an effective amount of at least two anti-filovirus glycoprotein antibodies or antigen-binding fragments thereof where at least one of the antibodies or fragments binds to its orthologous filovirus glycoprotein epitope on two or more filovirus species or strains.
