Provided herein, inter alia, are compositions and methods including recombinant oncolytic viruses expressing CD47 antibody for the treatment of diseases including cancer, immune disorders, and infectious disease.

The present describes monoclonal antibody to MUC1*.

Antibody drug conjugates (ADC's) that bind to 191P4D12 protein and variants thereof are described herein. 191P4D12 exhibits tissue specific expression in normal adult tissue, and is aberrantly expressed in the cancers listed in Table I. Consequently, the ADC's of the invention provide a therapeutic composition for the treatment of cancer.

Disclosed herein are methods for the direct readout of proteoforms and complexes thereof, such as immunoglobulins. The method may comprise ionizing a sample with an ionizer, wherein the sample comprises a mixture of different proteoforms or complexes thereof; detecting a multiplicity of ions generated by the ionization of the sample with a current detector; determining ion masses for each of the multiplicity of ions detected with the current detector with a mass analyzer; generating a mass-domain spectrum from the ion masses with the mass analyzer. The method may also comprise determining one or more metrics capturing the heterogeneity or relative abundance of proteoforms.

Methods for treating coronavirus disease 2019 (COVID-19), the disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections, is described. The methods can be used to reduce the severity of outcomes related to COVID-19, such as hospitalization and ventilation. For example, treatment of a subject with a therapeutic agent that neutralizes interleukin 13 (IL-13) can result in reduced risk for mechanical ventilation in the subject. Also described are methods of predicting risk of mechanical ventilation in subjects with COVID-19.

The present invention is directed to a monoclonal anti-human PD-L1 antibody, or a single-chain variable fragment (scFv), comprising V.sub.H having the amino acid of SEQ ID NO: 3 and V.sub.L having the amino acid of SEQ ID NO: 5. The present invention is also directed to a chimeric antigen receptor fusion protein comprising from N-terminus to C-terminus: (i) a single-chain variable fragment (scFv) of the present invention, (ii) a transmembrane domain, (iii) at least one co-stimulatory domains, and (iv) an activating domain. The inventors have shown that the PD-L1 CAR-T cells of the present invention are more effective than Avelumab PD-L1 CAR-T cells in killing several cancer cell lines. PD-L1 CAR-T can be used alone or in combination with other agent in an immunotherapy.

This disclosure provides compositions and methods for delivering a viral composition to cells, e.g., for cell surface receptor-mediated uptake, and enhanced viral transduction. Viral transduction can be achieved via a bifunctional bridging composition that includes a moiety that binds to a cell surface receptor ligand and a linked bridging moiety that binds to a viral composition. Also provided are modified viral compositions comprising a bridging composition specifically bound via its bridging moiety to the viral composition. Modified viral compositions and methods for reducing levels or titers of neutralizing antibodies in a subject in need of viral therapy, e.g., gene therapy, are provided. In some embodiments, the modified viral composition includes empty viral particles that bind and internalize neutralizing autoantibodies. Modified viral compositions including empty viral particles can be administered prior to viral therapy. Also provided are pharmaceutical compositions and kits including a bifunctional bridging composition and/or modified viral compositions.

The invention provides antibodies that specifically bind human α-synuclein with a high affinity and reduces α-synuclein spreading in vivo, recombinant polypeptides comprising said antibodies or antigen-binding fragment thereof and methods for generating such polypeptides, as well as compositions and methods for generating α-synuclein antibodies, and methods of using α-synuclein antibodies for the treatment of diseases of the central nervous system, in particular alpha-synucleinopathies.

Provided are anti-PD-1 antibodies or fragments thereof. In various example, the antibodies or fragments thereof includes a heavy chain variable region comprising heavy chain complementarity determining regions HCDR1, HCDR2, and HCDR3, and a light chain variable region comprising light chain complementarity determining regions LCDR1, LCDR2, and LCDR3. Methods of using the antibodies or fragments thereof for treating and diagnosing diseases such as cancer, infection or immune disorders are also provided.

The present disclosure relates to the pharmaceutical use of antagonists (e.g., an antibody or antigen-binding portion thereof) that specifically bind to FAM19A5 to promote a blood vessel normalization and treat a disease (e.g., cancer) in a subject in need thereof, e.g., by promoting a blood vessel normalization.
