Abstract: The present invention pertains to engineered T-cells, method for their preparation and their use as medicament, particularly for immunotherapy. The engineered T-cells of the invention are characterized in that the expression of beta 2-microglobulin (B2M) and/or class II major histocompatibility complex transactivator (CIITA) is inhibited, e.g., by using rare-cutting endonucleases able to selectively inactivating by DNA cleavage the gene encoding B2M and/or CIITA, or by using nucleic acid molecules which inhibit the expression of B2M and/or CIITA. In order to further render the T-cell non-alloreactive, at least one gene encoding a component of the T-cell receptor is inactivated, e.g., by using a rare-cutting endonucleases able to selectively inactivating by DNA cleavage the gene encoding said TCR component.

Abstract: The invention pertains to the field of adaptive cell immunotherapy. It provides with the genetic insertion of exogenous coding sequence(s) into genetically engineered immune cells to prevent cytokine release syndrome to arise during the course of cell therapy. These exogenous coding sequences are more particularly soluble human polypeptides placed 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 present invention provides composition kits and methods for treating cancer in a human by immunotherapy using successive doses of CAR-T cells with no or reduced anamnestic immune reaction in one individual (P).

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 I.

Abstract: Methods for developing engineered T-cells for immunotherapy that are both non-alloreactive and resistant to immunosuppresive drugs. The present invention relates to methods for modifying T-cells by inactivating both genes encoding target for an immunosuppressive agent and T-cell receptor, in particular genes encoding CD52 and TCR. This method involves the use of specific rare cutting endonucleases, in particular, TALE-nucleases (TAL effector endonuclease) and polynucleotides encoding such polypeptides, to precisely target a selection. of key genes in T-cells, which are available from donors or from culture of primary cells. The invention opens the way to standard and affordable adoptive immunotherapy strategies for treating cancer and viral infections.

Abstract: The present invention relates to methods of developing genetically engineered, preferably non-alloreactive T-cells for immunotherapy. This method involves the use of RNA-guided endonucleases, in particular Cas9/CRISPR system, to specifically target a selection of key genes in T-cells. The engineered T-cells are also intended to express chimeric antigen receptors (CAR) to redirect their immune activity towards malignant or infected cells. The invention opens the way to standard and affordable adoptive immunotherapy strategies using T-Cells for treating cancer and viral infections.

Abstract: Materials and methods for creating canola (e.g., Brassica napus) lines having oil with increased oleic acid content are provided herein. For example, a Brassica plant, plant part, or plant cell having an induced mutation in one or more FAD2 gene copies, oil produced from the plant, plant part, or plant cell has increased oleic acid content and decreased linolenic acid content as compared to oil produced from a corresponding wild type Brassica plant, plant part, or plant cell, wherein the mutation was induced by one or more rare cutting endonucleases targeted to the one or more FAD2 gene copies, and methods of making and using the Brassica plant, plant part or plant cell, are provided.
