Abstract: Engineered bacteriophage and methods of forming the bacteriophage are described. Multivalent bacteriophage are described that can include multiple different exogenous polypeptides at a surface of the capsid head. Vaccines and methods of forming and using vaccines are described. A vaccine can include an engineered bacteriophage that exhibits an immunogenic exogenous polypeptide at a surface of the bacteriophage. Multivalent bacteriophage and immunogenic bacteriophage are free of nucleic acids encoding the exogenous polypeptide(s).

Abstract: Cancer eradicating engineered bacteriophage are described that can display a high copy number of a targeting polypeptide that can bind a surface antigen of a cancer cell. The bacteriophage can also display a high copy number of a cancer therapy, one or more of a drug, a toxin, an inhibitor, a radionuclide, etc. The targeting polypeptides and the cancer therapies can be directly or indirectly fused to coat proteins of the phage. The engineered phage can exhibit high avidity for cancer cells and can deliver a large dose of a cancer therapy per particle to the cell.

Abstract: Sized-based detection techniques for detection of bio-nanoparticles are described. Detection nanoparticles and methods of forming the detection nanoparticles that can be utilized in the techniques are described. Detection nanoparticles can include modified bacteriophage that express a linking agent for a specific binding agent. Detection nanoparticles can bind a functional bio-nanoparticle with high specificity through specific binding of one or more entities unique to the functional bio-nanoparticle of interest. A detection nanoparticle can target an entity of a bio-nanoparticle that is relevant to its function, and as such, the methods can provide improvements in detection of complete and functional bio-nanoparticles. Size-based detection regimes can include particle displacement measurement techniques based upon Brownian motion.

Abstract: Engineered bacteriophage and methods of forming the bacteriophage are described. Multivalent bacteriophage are described that can include multiple different exogenous polypeptides that include specific binding agents for proteinaceous targets at a surface of the capsid head. Therapeutic compositions, e.g., antiviral compositions, and methods of forming are described. A therapeutic composition can include an engineered bacteriophage that includes a polypeptide binds a pathogen or binds a cellular receptor of a pathogen at a surface of the bacteriophage. The engineered bacteriophage are free of nucleic acids encoding the exogenous polypeptide(s).

Abstract: Provided herein are anti-ASPH chimeric antigen receptors (CARs), genetically modified immune effector cells, and use of these compositions to effectively treat ASPH expressing cancers.

Abstract: Extracellular domains of transmembrane heterodimeric proteins, particularly T cell receptor and major histocompatibility complex proteins, can be covalently linked to the heavy and light chains of immunoglobulin molecules to provide soluble multivalent molecular complexes with high affinity for their cognate ligands. The molecular complexes can be used, inter alia, to detect and regulate antigen-specific T cells and as therapeutic agents for treating disorders involving immune system regulation, such as allergies, autoimmune diseases, tumors, infections, and transplant rejection.

Abstract: Compositions comprising a cell in which a molecular complex with high affinity for its cognate ligand is bound to the surface of the cell are provided. To form the molecular complexes, extracellular domains of transmembrane heterodimeric proteins, particularly T cell receptor and major histocompatibility complex proteins, can be covalently linked to the heavy and light chains of immunoglobulin molecules. The molecular complexes can be used, inter alia, to detect and regulate antigen-specific T cells and as therapeutic agents for treating disorders involving immune system regulation, such as allergies, autoimmune diseases, tumors, infections, and transplant rejection. Optionally, identical antigenic peptides can be bound to each ligand binding site of a molecular complex.

Abstract: The present invention is directed to new ways to diagnosis lung cancer, especially at an early clinical stage. In addition, prognosis and the monitoring of therapeutic agents or other treatments, for lung cancer patients, can be accomplished with the disclosed methods. The methods also find use in allowing the assessment by pre-clinical animal efficacy studies to screen for the useful of therapeutic agents for treating lung cancer.

Abstract: The present invention relates to drug screening methods and methods of preventing neural tissue damage caused by ?-synuclein aggregation. These methods are especially useful in the design and development of inhibitors of Lewy body diseases and other synucleinopathies, and further useful in the treatment of such neurodegenerative diseases, particularly Parkinson's Disease.

Abstract: Disclosed are certain peptide linkers for conjugating drugs to ligands, and the resulting drug-linker-ligand molecules and compositions thereof. The conjugated molecules useful for the targeted delivery of drugs to the desired cells, and allow for the intracellular release of the drug in cases where the targeted antigen is internalized via the trans Golgi network and not the lysosomal pathway.

Abstract: The present invention provides methods of determining aggregation of &agr;-synuclein, which are a hallmark of Lewy body diseases such as Parkinson's disease. Also disclosed are inhibitors of the aggregation, including magnesium and &agr;-synuclein binding peptides. The inhibitors are useful in the treatment of Lewy body diseases.

The molecular complexes can be used, inter alia, to detect and regulate antigen-specific T cells and as therapeutic agents for treating disorders involving immune system regulation, such as allergies, autoimmune diseases, tumors, infections, and transplant rejection.
