The present application provides chimeric proteins comprising an antibody moiety that specifically binds to a component of an influenza virus or a variant thereof, and a positively charged mucoadhesive peptide fragment. Compositions comprising the chimeric proteins described herein are useful for preventing or treating an infection caused by an influenza virus or a variant thereof in an individual.

Chimeric protein comprising an anti-influenza virus antibody moiety and a mucoadhesive peptide fragment for preventing or treating influenza infections

The present application relates to compositions for preventing or treating infections. In some embodiments, the present application provides chimeric proteins comprising a target-binding moiety comprising an extracellular binding domain (EBD) of an angiotensin-converting enzyme 2 (ACE2) protein or a fragment thereof that specifically binds to an S protein, and a positively charged mucoadhesive peptide fragment. Compositions comprising the chimeric proteins described herein are useful for preventing or treating a viral infection in an individual, such as a coronavirus infection.

Compositions for preventing or treating coronavirus infections

The present application relates to compositions for preventing or treating viral and other microbial infections. In some embodiments, the present application provides chimeric proteins comprising a target-binding moiety that specifically binds to a pathogen that infects through a mucosa, and a positively charged mucoadhesive peptide fragment. Also provided are antibodies and constructs thereof that specifically binds to an S1 subunit of a spike protein of SARS-CoV-2. Compositions comprising the chimeric proteins, antibodies, or constructs described herein are useful for preventing or treating a microbial infection in an individual, such as a coronavirus infection.
