Provided is a high-affinity T cell receptor (TCR) that recognizes SSX2, wherein the TCR has the property of binding to a KASEKIFYV (SEQ ID NO: 29)-HLA A0201 complex, and the binding affinity of the TCR to the KASEKIFYV (SEQ ID NO: 29)-HLA A0201 complex is at least twice the binding affinity of a wild-type TCR to the KASEKIFYV (SEQ ID NO: 29)-HLA A0201 complex. Also provided is a fusion molecule of such a TCR with a therapeutic agent. Such a TCR can be used alone or in combination with a therapeutic agent to target tumor cells presenting the KASEKIFYV (SEQ ID NO: 29)-HLA A0201 complex.

The disclosure provides novel antigen-binding proteins that bind STEAP1 and methods of use.

Compositions that include anti-cancer, anti-tumor, and anti-microbial infection peptides are provided. In some embodiments, the compositions include 1-10 or more synthetic peptides that are between 8 and 50 amino acids long and include an amino acid sequence as disclosed herein. Also provided are in vitro populations of dendritic cells that include the compositions, in vitro populations of T cells capable of being activated uponbeing brought into contact with the populations of dendritic cells, antibodies and antibody-like molecules that specifically bind to complexes of an MHC class I molecule and the peptides, methods for using the disclosed compositions for treating and/or preventing cancer and/or microbial infections, methods for making cancer vaccines and anti-microbial vaccine, methods for screening peptides for inclusion in immunotherapy compositions, methods for determining a prognosis of a patient with a cancer and/or a microbial infection, kits that include the disclosed peptides, and methods for treating and/or preventing diseases, disorders, and/or conditions associated with hyperphosphorylation of MHC I peptides and/or MHC II peptides, inadequate PP2A activity, and/or undesirable CIP2A activity.

The disclosure provides compositions and methods that make use of a target protein that is capable of binding to a small molecule in order to form a complex, and a binding member that specifically binds to the complex, wherein the target protein is derived from a non-human protein and the small molecule is an inhibitor of the non-human protein. The non-human protein may be derived from a viral, bacterial, fungal or protozoal protein. These compositions and methods permit the controlled interaction of polypeptides that are individually fused to the target protein and binding member, respectively, and can be used to control the activity of dimerization-inducible proteins such as split transcription factors and split chimeric antigen receptors through the addition of the small molecule. The disclosure provides expression vectors, binding members, dimerization-inducible proteins, nucleic acids, cells, viral particles, kits, systems and methods that involve these components.

Antigen binding proteins that specifically recognize a target Melanoma-Associated Antigen A4 (MAGE-A4) peptide-MHC (pMHC), and nucleic acids encoding the same, are provided. Methods of producing antigen binding proteins that specifically recognize a target MAGE-A4 pMHC, and nucleic acid libraries encoding the same, are also provided.

The presently disclosed subject matter provides antigen-binding proteins (e.g., chimeric antigen receptors) and antibodies or antigen-binding portions thereof that bind to a Foxp3 peptide/MHC molecule complex. Such antibodies, fusion proteins and conjugates thereof are useful for inhibiting regulatory T cells and treating cancers.

Disclosed are an immunochemical assay device and a method of using the immunochemical assay device for detecting one or more targets or markers such as Cardiac Troponin I, NT-pro-BNP, D-dimer and/or cross-linked fibrin in a fluid sample.

Provided herein are various embodiments relating to antibodies that bind LILRB2. Anti-LILRB2 antibodies can be used in methods to treat disease, for example, cancer.

Disclosed herein are novel inhibitors of TGFβ1 activation with durable inhibitory effects. Methods directed to the selection of a suitable TGFβ inhibitor for various disease conditions and patient populations are also provided.

The present invention provides isolated T cell receptors (TCRs) that specifically bind to an HLA-displayed cancer testis antigen preferentially expressed antigen in melanoma (FRAME) peptide, as well as therapeutic and diagnostic methods of using those isolated TCRs.
