Methods of expanding T cells ex vivo comprising contacting the T cells with antibody molecules that bind to TCR Vβ regions are described. T cells comprise one or more nucleic acid molecule encoding an exogenous cellular receptor, for example, a chimeric antigen receptor (CAR) or an exogenous T cell receptor (TCR).

Provided herein are methods of treating cancer (e.g., NSCLC), which comprise administering to a human patient in need thereof: (a) a PD-1 antagonist; (b) an ILT4 antagonist; and (c) one or more chemotherapeutic agents. Also provided are pharmaceutical compositions and kits containing such agents for the treatment of cancer.

Provided are anti-FGFR2b antibodies or antigen-binding fragments thereof, isolated polynucleotides encoding the same, pharmaceutical compositions comprising the same, and the uses thereof.

The present disclosure includes antibodies that specifically bind integrin alpha 11 beta 1 (α11β1), as well as methods of making and using such antibodies.

The present invention is intended to provide: an anti-hCDCP1 antibody, which can be used as an active ingredient of anticancer agents having few side effects, etc.; and the aforementioned anti-hCDCP1 antibody that is formulated into ADC. Specifically, the present invention relates to an antibody that binds to human CDCP1 (CUB domain-containing protein 1), which has low binding property to human CD34-positive cells, or an antigen-binding fragment thereof. A representative example of the present antibody may be an antibody having heavy chain CDR1 comprising the amino acid sequence as set forth in SEQ ID NO: 25, heavy chain CDR2 comprising the amino acid sequence as set forth in SEQ ID NO: 26, heavy chain CDR3 comprising the amino acid sequence as set forth in SEQ ID NO: 27, light chain CDR1 comprising the amino acid sequence as set forth in SEQ ID NO: 29, light chain CDR2 comprising the amino acid sequence as set forth in SEQ ID NO: 30, and light chain CDR3 comprising the amino acid sequence as set forth in SEQ ID NO: 31.

Regulatory T cells (T.sub.reg cells), formerly known as suppressor T cells, are crucial for the maintenance of immunological tolerance. Their major role is to shut down T cell-mediated immunity toward the end of an immune reaction and to suppress auto-reactive T cells that escaped the process of negative selection in the thymus. Two major classes of CD4.sup.+ T.sub.reg cells have been described—naturally occurring T.sub.reg cells and adaptive T.sub.reg cells. Disclosed herein are methods for producing efficacious CAR T.sub.reg cells in a GMP-scalable system.

Provided are anti-FGFR2b antibodies or antigen-binding fragments thereof, isolated polynucleotides encoding the same, pharmaceutical compositions comprising the same, and the uses thereof.

This document provides methods and materials for assessing a mammal having or suspected of having cancer and/or for treating a mammal having cancer. For example, molecules including one or more antigen-binding domains (e.g., a single-chain variable fragment (scFv)) that can bind to a modified peptide (e.g., a tumor antigen), as well as method for using such molecules, are provided.

The present disclosure provides compositions and methods for cell transplantation therapy based on forced expression of an exogenous HLA-F protein in donor cells to be transplanted into a subject. In some embodiments, the donor cells express an exogenous chimeric HLA-F protein comprising an extracellular region comprising an HLA-F alpha 1 domain, an HLA alpha 2 domain, an HLA-F alpha 3 domain, a linker and a β2m protein.

The present disclosure provides anti-CCR8 antibodies, including compositions and methods of using such antibodies.
