  • Publication number: 20170198029
    Abstract: The present invention relates to a single chain antigen recognizing construct (scARC), which is composed of stabilized variable domains by the introduction of novel disulfide bonds, in order to prevent residual mis-pairing with endogenous ARC chains. The invention further discloses a method for the design of a novel structurally stabilized scARC, the method being based on the visual inspection of the crystal structure of the underlying scARC and the selection of appropriate amino acid substitutions to generate a novel disulfide bond in the protein structure. Furthermore, the invention discloses a method for the production of a cell which expresses the scARC of the invention. Also described are nucleic acids encoding an inventive scARC, as well as DNA and RNA constructs that allow for the expression of the inventive scARC.

  • Patent number: 8889141
    Abstract: The present invention provides a T-cell receptor (TCR) which binds to a peptide from latent membrane protein 2 (LMP-2) from the Epstein Barr Virus (EBV) having the amino acid sequence CLGGLLTMV (SEQ ID No. 1) when presented by a major histocampatability complex (MHC) molecule. The present invention also provides a nucleotide sequence encoding such a TCR, a vector comprising such a nucleotide sequence and its use to produce a EBV-specific T-cell. The present invention also provides the use of EBV-specific T-cell for cellular immunotherapy.
