Aspects of the disclosure relate to methods and compositions useful for in vivo and/or in vitro enzyme profiling. In some embodiments, the disclosure provides methods of in vivo enzymatic processing of exogenous molecules followed by detection of signature molecules as representative of the presence of active enzymes associated with diseases or conditions. In some embodiments, the disclosure provides compositions and in vitro methods for localization of enzymatic activity in a tissue sample.

The present invention provides a combination therapy for treating a tumor in a subject. The combination comprises two elements. The first is a polypeptide construct comprising an attenuated Type 1 interferon (IFN) linked to an antibody which binds to a cell surface-associated antigen expressed on the tumour cell and comprising a functional Fc region. The second is a CD47 antagonist which inhibits the interaction CD47 with the SIRPα receptor.

A method for suppression of progress of, suppression of recurrence of and/or treatment of cancer, by administering an Allergin-1 antagonist in a therapy of a cancer patient with insufficient therapeutic efficacy by a tumor immunotherapeutic agent, or a cancer therapy in combination with an anti-cancer drug.

Disclosed are proteins derived from the HGF/SF which are able to induce activation of the tyrosine kinase receptor MET and their uses, in particular to promote tissue regeneration. Further disclosed are nucleic acid molecules coding such protein, expression vectors containing such nucleic acid molecule, host cells containing such expression vectors, and related compositions.

Multispecific molecules that include i) a tumor-targeting moiety; and one, two or all of: (ii) an immune cell engager (e.g., chosen from an NK cell engager, a T cell engager, a B cell engager, a dendritic cell engager, or a macrophage cell engager); (iii) a cytokine molecule; and/or (iv) a stromal modifying moiety are disclosed. Additionally disclosed are nucleic acids encoding the same, methods of producing the aforesaid molecules, and methods of treating a cancer using the aforesaid molecules.

Provided herein are recombinant polypeptides comprising a SARS-CoV-2 S1 protein binding domain polypeptide and a GM-CSF polypeptide, polynucleotide sequences encoding the same, virus-like particles comprising the same, and methods for using these compositions for the treatment of a SARS-CoV-2 infection in a subject, and for detection of a SARS-CoV-2 antibodies in a subject.

The present disclosure provides FGF1 mutant proteins having one or more mutations in the heparin binding domain. Such mutants may also have an N-terminal deletion, point mutation(s), or combinations thereof. In some examples, the mutant FGF1 proteins have reduced mitogenic activity. Also provided are nucleic acid molecules that encode such proteins, and vectors and cells that include such nucleic acids. The disclosed FGF1 mutants can reduce blood glucose in a mammal, and in some examples are used to treat a metabolic disorder.

The instant invention provides soluble fusion protein complexes and IL-15 variants that have therapeutic and diagnostic use, and methods for making the proteins. The instant invention additionally provides methods of stimulating or suppressing immune responses in a mammal using the fusion protein complexes and IL-15 variants of the invention.

The invention features soluble fusion protein complexes comprising at least two soluble fusion proteins. For example, the first fusion protein is an anti-CD3 antibody covalently linked to an interleukin-15 (IL-15) polypeptide or functional fragment thereof. The second fusion protein comprises a binding domain that recognizes disease antigens, wherein this domain is covalently linked to a soluble interleukin-15 receptor alpha (IL-15Rα) polypeptide or a functional fragment thereof. One or both of the first and second fusion proteins further includes an immunoglobulin Fc domain or a functional fragment thereof, and the IL-15 domain of first fusion protein binds to the soluble IL-15Rα domain of the second fusion protein to form a soluble fusion protein complex. The invention further provides methods for making and using the complexes of the invention.

The present invention relates to new immunocytokines which are useful for the treatment of cancer. These fusion proteins comprise (i) an antibody or antigen-binding fragment thereof fused to (ii) a cleavable peptide linker, and (iii) cytokine, or functional fragments thereof. Methods of treatment using these immunocytokines are also disclosed.
