摘要:
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.
摘要:
The present invention relates to methods for improving therapeutic activity of NK cell, such as their cytotoxic/cytolytic activity, to be used in immunotherapy, by gene editing. In particular, these methods comprise a step of reduction or inactivation of gene expression using specific endonuclease such as TAL-nuclease, CRISPR or Argonaute. An additional genetic modification can be performed by (over)expressing at least one gene involved in N K function. The present invention encompasses also engineered NK cell, pharmaceutical composition containing the same.
摘要:
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.
摘要:
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.
摘要:
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.
摘要:
The invention provides engineered diatoms and methods of producing oil using diatoms. The invention also provides methods of modifying the lipids quantity and/or quality produced by diatom organisms through genome engineering. Also provided are oils, fuels, oleochemicals, chemical precursors, and other compounds manufactured from such modified diatoms.
摘要:
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.
摘要:
The present invention concerns new engineered immune cells expressing two CARs directed against two different targets, polynucleotides for preparing said immune cells, pharmaceutical compositions comprising said immune cells, and the use of said immune cells in the treatment of cancers.
摘要:
The present invention relates to engineered immune cells expressing new mesothelin (MLSN) specific chimeric antigen receptors (anti-mesothelin CAR) and their use in the treatment of solid tumors, particularly suited for allogeneic cell immunotherapy.
摘要:
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.
