The present invention relates to compositions and methods for antibody-mediated therapy. In particular, provided herein are engineered immunoglobulins with altered half-life.

The present invention provides an anti-HPV E7 protein monoclonal antibody and the use thereof. The antibody can detect the HPV16 E7 protein with high specificity and recognize the HPV18 E7 protein, thereby it can distinguish between the cancerous cervical epithelial cells and the cervical abnormal or non-cancerous cervical epithelial cells.

Provided are human antibodies that specifically bind to HBV Pre-S1 domain ligand and inhibit HBV or HDV infection, antibodies binding to a set of amino acid residues that are critical for viral receptor engagement, and uses of these antibodies to prevent, or treat or diagnose HBV or HDV infection.

The present disclosure provides methods for treating HBV infection using combination therapies, and related kits and compositions for use. The components of the combination therapies include an inhibitor of HBV gene expression or an agent that reduces HBV antigenic load, and an anti-HBV antibody.

The present disclosure provides compositions comprising anti-LMP2 TCR-T cell populations for the treatment of EBV-associated cancers and methods of making and using same.

This invention provides a monoclonal antibody that (i) specifically binds to the extracellular portion of human angiotensin converting enzyme 2 (hACE2); (ii) specifically inhibits binding of SARS-CoV-2 to the extracellular portion of hACE2; and (iii) does not significantly inhibit the ability of hACE2 to cleave angiotensin II and/or a synthetic MCA-based peptide. This invention also provides related recombinant AAV vectors, recombinant AAV particles, compositions, prophylactic and therapeutic methods, and kits.

The disclosure relates to the use of a combination of antibodies or antigen binding fragments thereof to hCMV; and to dosages, ratios and minimum trough serum concentrations of the antibodies. The combination is useful for the neutralization of hCMV, for example, in pregnant, immunocompromised or immunosuppressed patients undergoing bone marrow and organ transplants with a low occurrence of viral resistance.
