The technology described herein is directed to CAR polypeptides and systems comprising repressible proteases. In combination with a specific protease inhibitor, the activity of said CAR polypeptides and systems and cells comprising them can be modulated. Also described herein are methods of using said CAR polypeptides and systems, for example to treat various diseases and disorders.

Chimeric antigen receptor (CAR) modulation

Described herein are methods and compositions related to a modular engineered receptor polypeptide construct and their use in methods to modulate the activity of a cell. In particular, the disclosure relates to an engineered receptor polypeptide comprising, in brief, (i) an extracellular ligand binding domain having at least one ligand binding site, (ii) an optional flexible polypeptide linker, (iii) an intramolecular peptide that binds to the at least one ligand binding site in the extracellular ligand binding domain, (iv) a transmembrane domain comprising at least one γ-secretase cleavage site, and (v) an intracellular effector domain, where the intramolecular peptide that serves to regulate the activity of the engineered receptor polypeptide. Other aspects relate to cells comprising the engineered receptor polypeptide, and nucleic acid sequence encoding the engineered receptor polypeptide.

Engineered extracellular receptor constructs and uses thereof

The technology described herein is directed to polypeptide systems using drug-controlled peptide docking domains and cognate docking domain-binding peptides and their use to control cellular signaling, activity, and/or gene expression.
