    摘要: The present invention provides a chimeric antigen-receptor (CAR)-forming polypeptide comprising: (i) an antigen-binding domain; (ii) a coiled-coil spacer domain; (iii) a transmembrane domain; and (iv) an endodomain. The invention also provides a multimeric CAR formed by association of a plurality of CAR-forming polypeptides by virtue of association of their coiled-coil spacer domains.

    摘要: The present invention provides a chimeric antigen receptor (CAR) signalling system comprising; (i) a receptor component comprising an antigen binding domain, a transmembrane domain and a first binding domain; and (ii) an intracellular signalling component comprising a signalling domain and a second binding domain which specifically binds the first binding domain of the receptor component; wherein, binding of the first and second binding domains is disrupted by the presence of an agent, such that in the absence of the agent the receptor component and the signalling component heterodimerize and binding of the antigen binding domain to antigen results in signalling through the signalling domain, whereas in the presence of the agent the receptor component and the signalling component do not heterodimerize and binding of the antigen binding domain to antigen does not result in signalling through the signalling domain.

    摘要: The present invention provides a nucleic acid construct comprising the following structure: A-X-B in which X is a nucleic acid sequence which encodes a cleavage site; and A and B are nucleic acid sequences encoding a first and a second chimeric antigen receptor (CAR), each CAR comprising: (i) an antigen-binding domain; (ii) a spacer (iii) a trans-membrane domain; and (iv) an endodomain wherein the antigen binding domains of the first and second CARs bind to different antigens, wherein the spacer of the first CAR is different to the spacer of the second CAR and wherein one of the first or second CARs is an activating CAR comprising an activating endodomain and the other CAR is an inhibitory CAR comprising a ligation-off inhibitory endodomain; and wherein: (a) the first and/or second CAR comprises an intracellular retention signal; and/or (b) the signal peptide of the first or second CAR comprises one or more mutation(s) such that it has fewer hydrophobic amino acids.
