Abstract: Provided is a method for inducing T cells for a cell-based immunotherapy, comprising the steps of: (1) providing Rag 1 and/or Rag 2 gene knockout human pluripotent stem cells bearing genes encoding a T cell receptor specific for a desired antigen, and (2) inducing T cells from the pluripotent stem cells of step (1). Further provided are a cell-based immunotherapy method that uses the T cells for the cell-based immunotherapy and an iPS cell bank for the cell-based immunotherapy.
Abstract: A chimeric antigen receptor is provided, including an extracellular segment, including a single-chain antibody region binding to an antigen human CD19 and a hinge region, a trans-membrane segment, including a trans-membrane domain of human CD8? linked to the hinge region of the extracellular segment and embedded in cell membrane of T lymphocyte, and an intracellular segment, including an intracellular domain of human CD8?, an intracellular domain of molecule 4-1BB and an intracellular domain of CD3 ? chain. The single-chain antibody region includes a heavy-chain variable region and a light-chain variable region of the single-chain antibody, the hinge region includes an extracellular domain of human CD8 alpha (CD8?) of 55 amino acid residues and three alanine residues (AAA) located at the N-terminal of the extracellular domain of human CD8?, and the intracellular domain of human CD8? includes seven amino acid residues and linked to the trans-membrane domain of human CD8?.
Abstract: It has been found that a cell cluster obtained by causing just isolated cells to adhere to each other secretes adiponectin after transplantation to the heart, and thereby has an excellent therapeutic effect on heart disease.

Abstract: Novel lentivirus packaging systems engineered with a synthetic gene network having a positive feedback loop to amplify the expression of virus genes are provided. When co-transfected into a host cell with a transfer plasmid and envelope vector, extremely high viral titers are achieved when compared to transfection of a host cell with conventional third generation packaging systems. Methods for enhancing production of lentivirus, compositions comprising high titer lentivirus, and therapeutic methods based on delivery of lentiviral nucleic acid to target cells are also provided.

Abstract: The present invention provides methods for inducing tolerance and/or suppressing an immune response to an antigen by passing a cell suspension containing an anucleate cell through a constriction, wherein the constriction deforms the cell thereby causing a perturbation of the cell such that an antigen and/or tolerogenic factor enters the cell. In some embodiments, the anucleate cell is delivered to an individual and the antigen is delivered to and processed in a tolerogenic environment to induce tolerance and/or suppress an immune response to the antigen.

Abstract: The present invention pertains to engineered immune cells, method for their preparation and their use as medicament, particularly for immunotherapy. The engineered immune cells of the present invention are characterized in that at least one gene selected from a gene encoding GCN2 and a gene encoding PRDM1 is inactivated or repressed. Such modified Immune cells are resistant to an arginine and/or tryptophan depleted microenvironment caused by, e.g., tumor cells, which makes the immune cells of the invention particularly suitable for immunotherapy. The invention opens the way to standard and affordable adoptive immunotherapy strategies using immune cells for treating different types of malignancies.
Abstract: The present invention relates to the field of biotechnology, molecular biology and medicine, in particular to nuclease enzyme and use thereof. More specifically, the present invention relates to PaCas9 nuclease enzyme. The invention also relates to a nucleic acid encoding the nuclease, a genetic construct, an expression vector, a delivery vector, which comprise the nucleic acid, a liposome comprising the nuclease or nucleic acid encoding the nuclease, a method for producing a nuclease, methods for delivery, and a host cell comprising a nucleic acid encoding the nuclease.
