  • Publication number: 20160355875
    Abstract: The present invention relates to a method for the detection of a specific nucleic acid. Specifically, the invention provides a method and kits for detecting the presence of a specific nucleic acid using engineered DNA-binding domains such as Transcription Activator Like-Effector (TALE) domain or modular base-per-base binding domains (MBBBD). The method of the invention is particularly useful for in vitro diagnostic application.

  • Publication number: 20160333094
    Abstract: The present invention relates to a new generation of chimeric antigen receptors (CAR), under single-chain or multi-chain forms, the specificity of which, to a desired antigen, is conferred by a VNAR polypeptide derived from monomeric antibodies from cartilaginous fish. Such CARs, which aim to redirect immune cell specificity toward selected undesired malignant cells, are compact and thus particularly adapted to target hollow antigens such as ions channels of efflux pumps present at the surface of drug-resistant cells. The invention encompasses the polynucleotides, vectors encoding said multi-chain CAR and the isolated cells expressing them at their surface, in particularly for their use in immunotherapy.

  • Publication number: 20160297884
    Abstract: The invention provides CARs (CARs) that specifically bind to BCMA (B-Cell Maturation Antigen). The invention further relates to engineered immune cells comprising such CARs, CAR-encoding nucleic acids, and methods of making such CARs, engineered immune cells, and nucleic acids. The invention further relates to therapeutic methods for use of these CARs and engineered immune cells for the treatment of a condition associated with malignant cells expressing BCMA (e.g., cancer).

  • Publication number: 20160298098
    Abstract: The present invention relates to a method for the generation of compact Transcription Activator-Like Effector Nucleases (TALENS) that can efficiently target and process double-stranded DNA. More specifically, the present invention concerns a method for the creation of TALENs that consist of a single TALE DNA binding domain fused to at least one catalytic domain such that the active entity is composed of a singe polypeptide chain for simple and efficient vectorization and does not require dimerization to target a specific single double-stranded DNA tar et sequence of interest and process DNA nearby said DNA target sequence. The present invention also relates to compact TALENs, vectors, compositions and kits used to implement the method.

  • Publication number: 20150037809
    Abstract: The present invention relates to polypeptides and more particularly to Transcription Activator-Like Effector derived proteins that allow to efficiently target and/or process nucleic acids. Particularly, the present invention reports the characterization of TALE derived proteins that can efficiently target methylated DNA. The present invention more specifically relates to TALE derived proteins that allow activation of methylated promoters responsible for gene silencing.
