Abstract:
Safe, rapid and efficient methods for producing virus-specific or other antigen- specific T-cells from cord blood and other samples containing naive immune cells.
Abstract:
A method of treating a disease, such as cancer, by administering to a subject in need of such treatment an effective amount of allogeneic T cells with a MHC unrestricted chimeric receptor short time after partial lymphodepletion. The method also comprises administering one or more agents that delay egression of the allogeneic T cells from lymph nodes of said subject during adoptive transfer of said allogeneic T cells to the subject by trapping the T cells in the lymph nodes.
Abstract:
Die Erfindung betrifft ein Verfahren und Mittel zur Aktivierung von Gedächtnis-B-Lymphozyten, insbesondere zum Einsatz in der immunologischen Forschung und in der Medizin. Im erfindungsgemäßen Verfahren werden die Zellen mit einem Aktivierungsreagenz enthaltend Kermesbeeren-Mitogen, CpG-Oligonukleotide, IL-2 und IL-10 behandelt. Es ist überraschend, dass IL-2, IL-10 und CpG-Oligonukleotide die aktivierende Wirkung von Kermesbeeren-Mitogen verstärken. Die Erfinder haben herausgefunden, dass der Zusatz von IL-6, LPS, CD40-Ligand oder anti-CD40-Antikörper keine weitere aktivierende Wirkung auf die Gedächtnis-B-Lymphozyten hat. Dies ist überraschend, da IL-6 ein Wachstumsfaktor für B-Lymphozyten ist. Erfindungsgemäß sind im Aktivierungsreagenz daher kein IL-6 kein Lipopolysaccharid von Escherichia coli (LPS), kein Interleukin 6 (IL-6), kein CD40-Ligand und kein anti-CD40-Antikörper enthalten.

Abstract:
The invention, in the fields of medicine and molecular and cellular biology, relates to a method for promoting the success rate of in vitro production of cystic embryoid bodies from mammalian embryonic stem cells. The method of the present invention comprises the step of increasing the quantity of MAMA and/or of its homologues. An aspect of the invention consists in the use of MAMA and/or its homologues as agent of differentiation in an in vitro culture medium of mammalian embryonic stem cells. Another aspect of the invention is an embryonic stem cell line transfected with a sequence of nucleic acid encoding MAMA or with its homologous sequence of nucleic acid, and the cystic embryoid bodies therefrom.
Abstract:
Cell compositions consisting essentially of mammalian hematopoietic CXCR4 stem and progenitor cells capable to migrate in response to stromal-derived factor 1 (SDF-1) and/or capable to adhere to stromal cells in response to an adhesion-inducing agent, are provided for clinical transplantation. Hematopoietic CXCR4 stem and progenitor cells can be converted into CXCR4 cells by stimulation with a suitable agent. The composition consists preferably of human CD38 CXCR4 cells.
Abstract:
This invention relates to methods for the recombinant expression of a protein of interest in a mammalian host cell, use of an sh RNA or an si RNA directed against the Galectin-1 gene for increasing the expression of a protein of interest in a mammalian host cell and kits comprising said shRNA or an si RNA and a CHO cell.
Abstract:
The present invention relates generally to immunotherapy. Disclosed herein are methods for obtaining cytolytic differentiated NKG2A - NKG2C + NK cells with a given KIR specificity and also compositions comprising these cells as well as the use of these cells for therapy. The NK cell expansion methods provided herein also have non-therapeutic uses.
Abstract:
The present invention relates to the production of human retinal pigment epithelial cells comprising a step of incubating human pluripotent stem cells with binder molecules binding to terminal N-acetyllactosamine (Galβ1-4Glc NAc) and/or blood group H determinant type 2 (Fucα1-2Galβ1-4Glc NAc). Particularly, the invention relates to a use of lectin ECA in a culture of human pluripotent stem cells in order to support the stem cells to differentiate into retinal pigment epithelial cells.
