Abstract:
The present invention is in the field of genetic editing tools and methods of genetic engineering. It relates to the engineering of rare-cutting endonucleases designed to contract highly repetitive motives in chromosomes, which are at the origin of certain genetic diseases, in particular the so-called “triplet repeat diseases”, such as the Huntington disease. The invention encompasses the method for contracting the repetitive motives, the rare-cutting endonucleases for use to contract repetitive motives in a gene subjected to repeat disorder, the polynucleotides and vectors encoding thereof as well as the resulting pharmaceutical compositions.
Abstract:
The present invention relates to the design of improved TALE protein fusions useful as sequence-specific genomic reagents, such as TALE-nucleases and TALE base editors, displaying higher on-target/off-target activity ratios. Its goal is to produce safer reagents to genetically modify the genomes of different types of cells, especially mammalian cells, in particular for their use in gene therapy.
Abstract:
The present disclosure provides methods to genetically modify cells by insertion of an artificial exon (ArtEx) for delivery of therapeutic proteins in specific cell types and more particularly engineered cells for expression of a transgene into the brain of a patient.
Abstract:
The present invention relates to Chimeric Antigen Receptors (CAR) that are recombinant chimeric proteins able to redirect immune cell specificity and reactivity toward CLL1 positive cells. The engineered immune cells endowed with such CARs are particularly suited for immunotherapy for treating cancer, in particular leukemia.
Abstract:
The present invention relates to a method to engineer immune cell for immunotherapy. In particular said immune cells are engineered with chimeric antigen receptors, which be activated by the combination of hypoxia and ligand extracellular binding as input signals. The invention also relates to new designed chimeric antigen receptors which are able to redirect immune cell specificity and reactivity toward a selected target exploiting the ligand-binding domain properties and the hypoxia condition. The present invention also relates to cells obtained by the present method, in particular T-cells, comprising said chimeric antigen receptors for use in cancer treatments.
Abstract:
The invention pertains to the field of adaptive cell immunotherapy. It provides with the genetic insertion of exogenous coding sequence(s) that help the immune cells to direct their immune response against infected or malignant cells. These exogenous coding sequences are more particularly inserted under the transcriptional control of endogenous gene promoters that are sensitive to immune cells activation. Such method allows the production of safer immune primary cells of higher therapeutic potential.
Abstract:
The invention relates to the fields of immunotherapy, molecular biology and recombinant nucleic acid technology. In particular, the invention relates to a TALEN-modified human primary cell comprising in its genome, a modified human T cell receptor alpha gene with an insertion comprising at least, from 5′ to 3′, a polynucleotide encoding a self-cleaving peptide, a chimeric antigen receptor, wherein the cell has undetectable cell-surface expression of the endogenous alpha beta T cell receptor as compared to a TCR positive control cell and expresses a receptor to target a pathological cell, use of said cell for treating a disease, including cancer. The invention further relates to methods for producing such a TALEN-modified cell, and to means for detecting such an engineered human primary cell or other genetically modified human primary cell obtained using alternative and/or additional rare cutting endonucleases.

Abstract:
The present invention relates to a TCR KO—or TCR KO and dCK KO—engineered immune cells expressing a Chimeric Antigen Receptors (CAR) specific for CD123 that is a recombinant chimeric protein able to redirect immune cell specificity and reactivity toward CD123-expressing cells, and more particularly in which extracellular ligand binding is a scFV derived from a CD123 monoclonal antibody, conferring specific immunity against CD123 positive cells. The engineered immune cells endowed with such CD123 CARs are particularly suited for treating relapse refractory AML and blastic plasmacytoid dendritic cell neoplasm and for use as a treatment before bone marrow transplantation.
Abstract:
The invention relates to an inhibitory chimeric antigen receptor (N-CAR) comprising an extracellular domain comprising an antigen binding domain, a transmembrane domain, and, an intracellular domain wherein the intracellular domain comprises an Immunoreceptor Tyrosine-based Switch Motif ITSM, wherein said ITSM is a sequence of amino acid TX1YX2X3X4, wherein X1 is an amino acid X2 is an amino acid X3 is an amino acid and X4 is V or
