The present invention provides a composite comprising a novel antibody and at least one selected from the group consisting of a solid phase support and a labeled substance. The antibody consists of the amino acid sequence represented by SEQ ID NO: 08, and is capable of binding to an intranuclear protein of an influenza virus type A. The influenza virus type A is at least one selected from the group consisting of H1N1, H2N2, H3N2, and H7N9. The antibody is bound to the at least one selected from the group consisting of a solid phase support. The present invention also provides a detection device and a detection method using the composite.

The present invention relates in part to amino acid sequences that are directed against and/or that can specifically bind to an envelope protein of a virus, as well as to compounds or constructs, and in particular proteins and polypeptides, that comprise or essentially consist of one or more such amino acid sequences.

The present application describes an antibody-coding, non-modified or modified RNA and the use thereof for expression of this antibody, for the preparation of a pharmaceutical composition, in particular a passive vaccine, for treatment of tumours and cancer diseases, cardiovascular diseases, infectious diseases, autoimmune diseases, virus diseases and monogenetic diseases, e.g. also in gene therapy. The present invention furthermore describes an in vitro transcription method, in vitro methods for expression of this antibody using the RNA according to the invention and an in vivo method.

Immunogenic compositions comprising partially glycosylated viral glycoproteins for use as vaccines against viruses are provided. Vaccines formulated using mono-, di-, or tri-glycosylated viral surface glycoproteins and polypeptides provide potent and broad protection against viruses, even across strains. Pharmaceutical compositions comprising monoglycosylated hemagglutinin polypeptides and vaccines generated therefrom and methods of their use for prophylaxis or treatment of viral infections are disclosed. Methods and compositions are disclosed for influenza virus HA, NA and M2, RSV proteins F, G and SH, Dengue virus glycoproteins M or E, hepatitis C virus glycoprotein E1 or E2 and HIV glycoproteins gp120 and gp41.

The present disclosure provides nanoparticles comprising a polymer and a plurality of TLR agonist moieties conjugated to the polymer and present on the surface of the nanoparticles. Methods of producing the nanoparticles, hydrogels comprising the nanoparticles, and vaccines comprising the nanoparticles and/or hydrogels are also provided. Methods for inducing an antigen-specific humoral immune response or enhancing cancer immunotherapy in a subject are also provided.

Provided herein are antibodies that bind to neuraminidase (NA) of different strains of influenza B virus, host cells for producing such antibodies, and kits comprising such antibodies. Also provided herein are compositions comprising antibodies that bind to NA of different strains of influenza B virus and methods of using such antibodies to diagnose, prevent or treat influenza virus disease.

Methods for providing novel compositions useful as influenza immunogens are provided. The compositions enable a host response to immunogen sites normally not recognized by a host. The novel immunogens can be used as vaccines or to develop antibodies.

Provided is a method for producing trimeric and tetrameric IgA antibodies, the method including mixing dimeric IgA antibodies and monomeric IgA antibodies.

The present invention relates to methods exogenous nucleic acid molecules, such as RNA, that encode an antibody or antigen-binding fragment of an antibody, and optionally encode a cellular modulation factor and/or a potentiation factor. The cellular modulation factor is a factor that results in increased expression of the antibody and/or antigen-binding fragment. The potentiation factor is a factor that provides desired antibody effector or other properties. The exogenous nucleic acid molecules can be DNA or RNA, as mRNA (including self-replication RNA and non-self-replicating RNA). The invention also relates method for administering the exogenous nucleic acid molecules to a subject to achieve production of the encoded antibody or antigen-binding fragment in the subject to provide, for example, prophylactic or therapeutic passive immunity.
