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.

Embodiments herein relate to compositions and methods for stabilizing Flaviviruses. In certain embodiments, compositions and methods disclosed herein concern stabilizing live, attenuated or unattenuated (e.g. live whole) flaviviruses. Other embodiments relate to compositions and methods for reducing degradation of live, attenuated or unattenuated flaviviruses. Other embodiments relate to improved formulations for prolonging stabilization of live attenuated or unattenuated Flaviviruses during manufacturing, storage, accelerated storage and transport. Yet other embodiments relate to uses of compositions disclosed herein in kits for transportable applications and methods.

The present disclosure provides T-cell modulatory multimeric polypeptides that comprise an immunomodulatory polypeptide that exhibits reduced binding affinity to a cognate co-immunomodulatory polypeptide. A T-cell modulatory multimeric polypeptide is useful for modulating the activity of a T cell, and for modulating an immune response in an individual.

Provided are dosing regimens of polyomavirus neutralizing antibodies and related methods and pharmaceutical compositions for treating polyomavirus infections.

The present disclosure provides a method of making a site-specific antibody to a target of interest.

The present invention relates to immunogenic immune complexes, related compositions, and related methods.

This disclosure provides a multimeric hepatitis B virus (HBV) protein binding molecule, e.g., a dimeric IgA or a pentameric or hexameric IgM binding molecule, comprising at least two bivalent binding units, or variants or fragments thereof, each comprising at least two antibody heavy chain constant regions or fragments thereof, wherein each heavy chain constant region or fragment thereof is associated with an HBV antigen binding domain. The disclosure also provides compositions comprising the multimeric binding molecules, polynucleotides encoding the multimeric binding molecules, and methods to make and use the multimeric binding molecules.

A new monoclonal antibody targeting the VP-1 protein of the capsid of the BK polyomavirus, fragments thereof, and uses of same for detecting infection with the BK polyomavirus. The monoclonal antibody is capable of recognizing at least all serotypes Ia, Ib2, II, III and IV of the VP-1 protein of the BK polyomavirus.

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.

The present disclosure relates to pharmaceutical compositions that comprise an antibody that neutralizes infection of hepatitis B virus (HBV). In addition, the present disclosure relates to the use of the pharmaceutical compositions in the treatment of HBV infection.
