  • Publication number: 20230287454
    Abstract: The invention pertains to the field of adaptive cell immunotherapy. It aims at reducing the occurrence of translocations and cell deaths when several specific endonuclease reagents are used altogether to genetically modify primary immune cells at different genetic loci. The method of the invention allows to yield safer immune primary cells harboring several genetic modifications, such as triple or quadruple gene inactivated cells, from populations or sub-populations of cells originating from a single donor or patient, for their subsequent use in therapeutic treatments.

  • Publication number: 20220010292
    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 single polypeptide chain for simple and efficient vectorization and does not require dimerization to target a specific single double-stranded DNA target sequence of interest and process DNA nearby the DNA target sequence. The present invention also relates to compact TALENs, vectors, compositions and kits used to implement the method.
