Abstract: The present disclosure relates to recombinant fusion proteins comprising an extracellular domain of the human angiotensin-converting enzyme 2 (ACE2), optionally having altered amino acid residues that result in increased binding affinity for the S1 spike protein of SARS-CoV-2, linked to a human immunoglobulin Fc region, that can extend the protein half-life (T1/2) and/or the duration of action as a decoy receptor, and compositions and methods of use of these fusion proteins.

Abstract: Methods and materials providing a route for the use of transgenic plants as bio-factories to produce therapeutic miRNAs are described. The plants can be ingestible and can be used to deliver to a subject in need thereof a therapeutic miRNA by ingestion of the bioengineered plant tissue that carries an exogenous genetic sequence for the therapeutic miRNA. The therapeutic miRNA can be useful in treating a disease state such as cancer. The therapeutic miRNA can be a mammalian tumor suppressor miRNA.

Abstract: The immunoadhesions of the present invention are useful in treating rhinovirus infections. The immunoadhesions contain a chimeric ICAM molecule and may optionally also contain J chain and secretory compounds. The chimeric ICAM molecule is a fusion protein that has a rhinovirus receptor protein linked to an immunoglobulin protein. This invention also includes the greatly increased and improved method of producing immunoadhesions in plants. Each of the components of an immunoadhesin is produced in a plant cell and thereby assembles within the plant cell. This method of producing the immunoadhesions of the present invention results in the efficient and economic production of these molecules. The present invention also contemplates the production of immunoadhesions in a variety of eukaryotic cells including plants and mammalian cells. The immunoadhesions of the present invention are useful as a therapeutic against the common cold in humans which is caused by rhinoviruses.

Abstract: Immunoadhesins active against infectious bacterial agents, e.g., the bacterium responsible for anthrax, are described and claimed. These chimeric molecules feature stabilizing immunoglobulin portions linked to bacterial proteins having affinity for host receptors. Methods of using these immunoadhesins are also desribed.
