Some embodiments of the invention include virus-like particle (VLP) binding agents, and related polynucleotides, cells, methods of making, and compositions. Other embodiments of the invention include methods of detecting VLPs, parvovirus, erythrovirus or parvovirus B19 using a VLP binding agent and diagnostic methods for parvovirus, erythrovirus or parvovirus B19. Further embodiments include methods for administering VLP binding agents to an animal. Other embodiments include treating parvovirus, erythrovirus or parvovirus B19 infections and other diseases. Additional embodiments of the invention are also discussed.

Methods and compositions for regulating activity of a poxvirus viral polymerase by modulating the assembly and/or interaction of one or more subunits of the viral polymerase are described.

Provided are antibodies that specifically bind Vaccinia Virus (VV) A56 or B5 antigen. Also provided are fusion proteins and conjugates that comprise the antibodies. Pharmaceutical compositions and kits that comprise the antibodies, fusion proteins and conjugates are also provided. Aspects of the present disclosure further include methods of using the antibodies, fusion proteins and conjugates, e.g., for therapeutic purposes. In certain embodiments, provided are methods that comprise administering an antibody, fusion protein or conjugate of the present disclosure to an individual having cancer, wherein the individual comprises cancer cells infected with VV, and wherein the antibody, fusion protein or conjugate is targeted to the infected cancer cells by VV antigens expressed on the surface of the infected cancer cells. Aspects of the present disclosure further include methods of targeting an antibody, fusion protein, or conjugate that specifically binds an oncolytic virus (OV) antigen to cancer cells in an individual.

The present invention relates to a tumor-targeting protein or a fragment thereof, an antibody binding thereto and a use thereof. More specifically, the present invention relates to a vector containing a nucleic acid coding for the protein A56 or a fragment thereof, and a use thereof. In addition, the present invention relates to an antibody binding to the protein A56 or a fragment thereof, and a use thereof. The vector containing the nucleic acid coding for the protein A56, a fragment thereof or a mutant thereof of the present invention uses an oncolytic virus as the vector, and thus, when administered in an individual, specifically kills only cancer cells, primarily. In addition, cancer cells which have survived even after being infected with the oncolytic virus express the protein A56 on the cell surfaces thereof, and thus may be targeted for secondary anticancer therapy. Thus, cancer may be effectively treated when the vector containing the nucleic acid coding for the protein A56 or a fragment thereof, and the antibody binding to A56, according to one embodiment of the present invention, are used.

Fc regions comprising modification to increase the affinity of association between the Fc region and TRIM21 are disclosed. Also disclosed are constituent polypeptides of such Fc regions, antigen-binding molecules and immunogens comprising such Fc regions, and nucleic acids encoding and methods using such Fc regions, antigen-binding molecules and immunogens.

Provided are novel human-derived antibodies specifically recognizing polyomavirus polypeptides, preferably capable of binding to polyomaviruses of the type of JC virus (JCV) and/or BK virus (BKV) as well as methods related thereto. Furthermore, assays and kits related to antibodies specific for polyomaviruses, polyomavirus VP1 and or polyomavirus VP1 Virus-Like Particles (VLPs), preferably of the type of JCV and/or BKV, are disclosed. The human-derived antibodies as well as binding fragments, derivatives and variants thereof can be used in pharmaceutical and diagnostic compositions for polyomavirus targeted immunotherapy and diagnostics.

The present disclosure relates to methods of producing monoclonal antibodies in animals. In particular, the disclosure provides a method of producing, in vivo, antibodies against viral capsids (VCs) derived from a non-enveloped virus (NEV). The method includes administering to a subject, by hydrodynamic-based transfection, a first set of genetic material encoding NEV structural proteins to induce the subject's intracellular translation and assembly of the proteins into viral capsids. The method also includes administering a second set of genetic material encoding NEV non-structural proteins to facilitate the intracellular assembly of the NEV structural proteins. Thus, this method may be used to produce subject-generated antibody-producing cells that secrete anti-VC antibodies that may be harvested and screened for monoclonal anti-VC antibodies.

This disclosure provides modified cytomegalovirus (CMV) gL proteins and complexes comprising gL proteins. The modified gL proteins remain intact and are able to form complexes with other CMV proteins.

The present disclosure provides a canine parvovirus (CPV) nanobody CPV-VHH-H1 and use thereof, belonging to the technical field of immunology. A heavy-chain variable region sequence of the nanobody CPV-VHH-H1 has the amino acid sequence set forth in SEQ ID NO: 1; and a gene encoding the nanobody CPV-VPP-H1 has the nucleotide sequence set forth in SEQ ID NO: 2. In the present disclosure, a nanobody immune library of the CPV is constructed by a phage display technology, a specific anti-CPV nanobody CPV-VHH-H1 is obtained by screening, and it is verified by experiments that the nanobody may specifically bind to the CPV. The present disclosure is expected to develop a new nanobody preparation for use in clinical diagnosis and treatment of the CPV, and provides a certain theoretical reserve for applying the nanobody to the field of veterinary biological products.
