The present disclosure is directed to anti-VP1 antibodies, antibody fragments, and their uses for the reducing the likelihood or treatment of polyoma virus infection.

The present invention relates to anti-VP1 antibodies, antibody fragments, and their uses for the prevention and treatment of polyoma virus infection and associated diseases.

For many diseases due to microbes or the like, proliferation of microbes themselves is a cause of a symptom. However, there were cases where a substance released by the microbes is a cause of a symptom. In such cases, when attempting to treat a disease with an antibody, it was necessary to obtain an antibody against an antigen that is a substance causing the disease. However, it was difficult to find the underlying substance causing the disease among substancesa released by the microbes. An antibody (polyclonal) binding to not only an antigen but also to a substance, which is secreted by the antigen and accelerates the deterioration of a symptom, is obtained by immunizing birds with a lysis solution produced from lysing microbial cells as an antigen. Further, an antibody obtained with a surface protein of a virus as an antigen is expected to inhibit an infection by a virus.

A target protein for viral vector-based anticancer therapy, and a binding molecule or a fragment thereof which specifically binds thereto are disclosed. A conformational epitope of protein A56, and a binding molecule or a fragment thereof which specifically binds thereto are disclosed. The A56-binding molecule or a fragment thereof, which binds to a conformational epitope of A56 forms a specific structural bond with A56 and shows high affinity thereto. Administering a vaccinia virus-based oncolytic virus, A56 is expressed on the cancer cell surface in various carcinomas. The A56-binding molecule or a fragment thereof effectively targets A56 that is specifically expressed on the cancer cell surface, which enables targeted therapy for cancer cells that have survived even infection with an oncolytic virus, thereby providing effective anticancer therapy.

The disclosure relates to the field of molecular virology and immunology, and discloses an anti-HPV6 L1 protein antibody and a detection method using the antibody. The antibody or its antigen-binding fragment comprises a light chain variable region or part thereof and/or a heavy chain variable region or part thereof, the light chain variable region or part thereof comprises one or more of the light chain CDR1-3 whose amino acid sequence is SEQ ID NOs: 5-7 respectively; the heavy chain variable region or part thereof comprises one or more of heavy chain CDR1-3 whose amino acid sequence is SEQ ID NOs: 8-10. The antibody has strong binding ability to HPV6L1 antigen, and has no cross-reaction with HPV11, 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58 and 59 types, and is suitable for performing immunogenicity evaluation of HPV vaccine as a detection antibody in ELISA quantification.

Provided are binding molecules, such as TCRs or antigen binding fragments thereof and antibodies and antigen-binding fragments thereof, such as those that recognize or bind human papilloma virus (HPV) 16, including HPV 16 E6 and HPV 16 E7. Also provided are engineered cells containing such binding molecules, compositions containing the binding molecules or engineered cells, and methods of treatment, such as administration of the binding molecules, engineered cells, or compositions.

The present invention relates to a specific antibody of a protein antigen capable of binding to nucleic acids, or a fragment or a derivative of such an antibody binding to the antigen, for use as a drug, in particular in the treatment or prevention of inflammation, due especially to an infection or an autoimmune disease, characterised in that the antibody, fragment or derivative has a reduced capacity to bind to the Fc?RIIA receptor and/or an increased capacity to bind to the Fc?RIIB receptor. The antibody, fragment or derivative is preferably without an Fc domain, or with a modified Fc domain with a reduced capacity to bind to Fc?RIIA and optionally Fc?RIIA (or even a reduced capacity to bind to all Fc?R), and/or with a modified Fc domain with an increased capacity to bind to Fc?RIIB.

The present disclosure is directed to methods and compositions for the diagnosis and/or treatment of tumors, such as ocular tumors, using virus-like particles conjugated to photosensitive molecules.

A ferritin protein is mutated to have a foreign peptide fused to the outer surface thereof so that a binding force to a human transferrin receptor is reduced. The peptide can exhibit activities of various foreign peptides. The foreign peptide is a pharmacologically active peptide, and the foreign peptide may include a ligand or a fragment thereof, a receptor or a fragment thereof, an antibody or a fragment thereof including an antigen binding region (CDR), which are capable of binding to an immune checkpoint molecule; or a disease antigen epitope.

Disclosed are novel HPV E6 and HPV E7 binding molecules and methods of their use in the treatment of HPV and cancers resulting from an HPV infection.
