Abstract: This document provides methods and materials involved in binding a binder (e.g., an antibody, antigen binding fragment, antibody domain, CAR, cell engager, and/or ADC) to a CD66e polypeptide. For example, binders (e.g., antibodies, antigen binding fragments, antibody domains, CARs, cell engagers, and/or ADCs) that bind to a CD66e polypeptide and methods and materials for using one or more such binding molecules to treat a mammal (e.g., a human) having cancer are provided.

Abstract: This document provides methods and materials involved in binding a binder (e.g., an antibody, antigen binding fragment, antibody domain, CAR, cell engager, and/or ADC) to a mesothelin polypeptide. For example, binders (e.g., antibodies, antigen binding fragments, antibody domains, CARs, cell engagers, and/or ADCs) that bind to a mesothelin polypeptide and methods and materials for using one or more such binding molecules to treat a mammal (e.g., a human) having cancer are provided.

Abstract: Some embodiments of the methods and compositions provided herein include methods and materials involved in binding a binder (e.g., an antibody, antigen binding fragment, antibody domain, CAR, cell engager, and/or ADC) to an FGFR4 polypeptide. For example, binders (e.g., antibodies, antigen binding fragments, antibody domains, CARs, cell engagers, and/or ADCs) acidic box that bind to an FGFR4 polypeptide and methods and materials for using one or more such binding molecules to treat a mammal (e.g., a human) having cancer are provided. Some embodiments of the methods and compositions provided herein include chimeric antigen receptors (CARs) which specifically bind to fibroblast growth factor receptor 4 (FGFR4). Some embodiments include nucleic acids encoding such CARs, and cells containing such CARs. Some embodiments include the use of such CARs in safe and effective therapies for a cancer, such as an FGFR4-expressing cancer, such as a rhabdomyosarcoma.

Abstract: Some embodiments provided herein also include methods and materials involved in binding a binder (e.g., an antibody, antigen binding fragment, antibody domain, CAR, cell engager, and/or ADC) to an IL1RAP polypeptide. For example, binders (e.g., antibodies, antigen binding fragments, antibody domains, CARs, cell engagers, and/or ADCs) that bind to an IL1RAP polypeptide and methods and materials for using one or more such binding molecules to treat a mammal (e.g., a human) having cancer are provided. Some embodiments of the methods and compositions provided herein include chimeric antigen receptors (CARs) which specifically bind to interleukin-1 receptor accessory protein (IL1RAP). Some embodiments include nucleic acids encoding such CARs, and cells containing such CARs. Some embodiments include the use of such CARs in safe and effective therapies for a cancer, such as an IL1RAP-expressing cancer, such as a Ewing's sarcoma and acute myeloid leukemia (AML).

Abstract: The present invention provides various ADAM17 binding molecules (including antibodies and fragments thereof), compositions comprising such ADAM17 binding molecules, and methods of using such ADAM17 binding molecules and compositions, for example in inhibiting binding of ADAM17 to ADAM17 substrates (such as ErbB ligands), in inhibiting the proliferation of cancer cells, and in treating cancer.

Abstract: This document provides methods and materials involved in binding a binder (e.g., an antibody, antigen binding fragment, and/or antibody domain) to a SARS-CoV-2 antigen. For example, binders (e.g., antibodies, antigen binding fragments, and antibody domains) that bind to a SARS-CoV-2 polypeptide and methods and materials for using one or more such binding molecules to treat a mammal (e.g., a human) having COVID-19 (or a viral infection caused by SARS-CoV-2) are provided.
