Abstract: The present invention relates to methods for developing engineered T-cells for immunotherapy and more specifically to methods for modifying T-cells by inactivating at immune checkpoint genes, preferably at least two selected from different pathways, to increase T-cell immune activity. 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 highly efficient adoptive immunotherapy strategies for treating cancer and viral infections.

Abstract: The present invention relates to methods for developing engineered T-cells for immunotherapy that are non-alloreactive. The present invention relates to methods for modifying T-cells by inactivating both genes encoding T-cell receptor and an immune checkpoint gene to unleash the potential of the immune response. 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 disclosure provides a method of generating a stable producer cell line. The generation of stable producer cell lines, such as those provided in accordance with the present invention, increases the reproducibility and ease of creating high titer lentiviral stocks while easing biosafety concerns and the variation in expressed envelope proteins defines the tropism of the generated virus. The present disclosure also provides for a novel lentiviral transfer vector plasmid.
Abstract: The invention relates to methods of producing eukaryotic cell libraries encoding a repertoire of binding molecules (“binders”), wherein the methods use a site-specific nuclease for targeted cleavage of cellular DNA to enhance site-specific integration of binder genes through endogenous cellular repair mechanisms. Populations of eukaryotic cells are produced in which a repertoire of genes encoding binders are integrated into a desired locus in cellular DNA (e.g., a genomic locus) allowing expression of the encoded binding molecule, thereby creating a population of cells expressing different binders.

Abstract: The invention provides a chimeric antigen receptor (CAR) which can specifically bind to a BCMA protein comprising a BCMA binding structural domain, a transmembrane domain, a costimulatory domain, and an intracellular signaling domain. The invention also provides uses of the CAR in treating diseases or conditions linked to the expression of BCMA.
Abstract: There are disclosed hybrid proteins comprising at least one signal sequence; at least one DNA binding domain; and at least one cell penetrating peptide (CPP) domain. In embodiments the CPP domain is a TAT domain, and the DNA binding domain is a HU domain. There is also disclosed the use of the hybrid proteins to introduce exogenous DNA into target cells, and methods for introducing exogenous DNA into target cells using the hybrid proteins.

Abstract: The invention refers to a composition for the fixation of histological preparations, comprising a solution of glyoxal, wherefrom acids, normally present in the commercially available glyoxal, have been removed. The composition of the invention provides an optimal fixative for the preservation of structure, antigenic components and nucleic acids in tissues. The acid-free glyoxal has limited toxicity, is not considered as a carcinogenic agent and represents a valid alternative to formalin for the fixation of tissues and cells.
Abstract: The present invention relates to the purification of poloxamers to be used as cell culture media additives. Activated carbon can be used to remove hydrophobic high molecular weight components which reduce the efficacy of poloxamers as cell culture additives.

Abstract: The present disclosure provides infectious recombinant adeno-associated virus (rAAV) virions that comprise a variant capsid protein and a heterologous nucleic acid. The present disclosure further provides the variant adeno-associated virus (AAV) capsid proteins (and/or a nucleic acid encoding the variant AAV capsid proteins), which confer to an infectious rAAV virion an increased resistance to human AAV neutralizing antibodies. The present disclosure further provides host cells comprising an infectious rAAV virion and/or a nucleic acid encoding a subject variant AAV capsid protein. The present disclosure further provides methods of delivering a heterologous nucleic acid to a target cell where the target cell is contacted with a subject infectious rAAV virion. The present disclosure further provides methods of delivering a gene product to an individual, the methods generally involving administering an effective amount of a subject rAAV virion to an individual in need thereof.
