Provided herein are recombinant T-cell receptors (TCRs) that can selectively recognize the MAGE-A4-derived peptide GVYDGEEHSV or KVEEHVVRV when presented by HLA-A*0201 sufficiently to activate the recombinant T cell. TCRs provided herein were thoroughly screened for lack of cross-reactivity with similar peptides that may be presented by normal cells or tissue and for alloreactivity.

The present disclosure provides improved compositions for adoptive T cell therapies for treating, preventing, or ameliorating at least one symptom of a cancer, infectious disease, autoimmune disease, inflammatory disease, and immunodeficiency, or condition associated therewith.

The present invention provides a modified T cell or population of modified T cells comprising a heterologous recombinant T cell receptor (TCR) and heterologous recombinant co-receptor, additionally provided are methods of producing the modified T cell or population of modified T cells and their use in the treatment of cancer.

The present disclosure provides engineered immune cells and methods for their creation and use. The immune cells comprise activating and blocking receptors, which form into micro-clusters upon contacting a target or non-target cell.

MAGE-A4, or Melanoma-Associated Antigen A4, is a cancer-testis antigen (CTA) on the X chromosome. The present disclosure provides MAGE-A4-specific chimeric antigen receptors and cells expressing such chimeric antigen receptors. In certain embodiments, engineered cells expressing the chimeric antigen receptors of the present disclosure are capable of inhibiting the growth of tumors expressing MAGE-A4. The engineered cells of the present disclosure are useful for the treatment of diseases and disorders in which an upregulated or induced MAGE-A4-targeted immune response is desired and/or therapeutically beneficial. For example, engineered cells expressing the MAGE-A4-specific chimeric antigen receptors of the present disclosure are useful for the treatment of various cancers.

This disclosure provides for engineered T cell Receptors (TCRs), cells comprising the TCRs, and methods of making and using the TCRs. The current disclosure relates to TCRs that specifically recognize epitope(s) from tumor antigen MAGE-A4. Accordingly, aspects of the disclosure relate to an engineered T-cell Receptors (TCRs), nucleic acids encoding the TCRs, and cells comprising the nucleic acids and TCRs. Also provided are compositions comprising the cells, nucleic acids, or engineered TCRs of the disclosure, methods of making the cells and methods of using the embodiments of the disclosure for therapeutic treatments.
