Abstract:
A method of treating a renal, hepatic or enzyme-deficiency disorder in a subject in need thereof is disclosed. The method is effected by transplanting into the subject tissue derived from a human or porcine, kidney or liver, the kidney or liver being at a selected gestational stage.
Abstract:
The present invention provides a method of treating a disease in a subject in need thereof via non-syngeneic graft administration without or with reduced concomitant graft rejection. The method comprises administering to the subject a therapeutically effective graft being non-syngeneic with the subject, and a dose of tolerogenic cells being non-syngeneic with both the subject and the graft for preventing or reducing graft rejection in the subject, thereby treating the disease in the subject
Abstract:
A method of generating an isolated population of non graft versus host disease (GvHD) inducing cells comprising a central memory T-lymphocyte (Tcm) phenotype, the cells being tolerance inducing cells and/or endowed with anti-disease activity, and capable of homing to the lymph nodes following transplantation is disclosed. The method comprising: (a) providing a population of at least 70% memory T cells; (b) contacting the population of memory T cells with an antigen or antigens so as to allow enrichment of antigen reactive cells; and (c) culturing the cells resulting from step (b) in the presence of cytokines so as to allow proliferation of cells comprising the Tcm phenotype. Cells generated by the method, pharmaceutical compositions and methods of treatment are also disclosed.
Abstract:
A method of generating a population of genetically modified veto cells is disclosed. The method comprising: (a) providing a population of cells comprising T cells, the T cells comprising at least 40% memory CD8+ T cells; (b) culturing the population of cells comprising T cells with an antigen or antigens under conditions which allow enrichment of tolerance-inducing antigen-specific cells having a central memory T-lymphocyte (Tcm) phenotype, the cells being depleted of graft versus host (GVH) reactivity; and (c) transducing the cells with a polynucleotide encoding a heterologous cell surface receptor comprising a T cell receptor signaling module, thereby generating the population of genetically modified veto cells.
Abstract:
A method of treating or preventing a sickle cell disease in a subject in need thereof is disclosed. The method comprising: (a) transplanting immature hematopoietic cells into the subject; and (b) administering to the subject a therapeutically effective amount of an isolated population of non-GVHD inducing anti-third party cells comprising cells having a central memory T-lymphocyte (Tcm) phenotype, the cells being tolerance inducing cells and capable of homing to the lymph nodes following transplantation.
Abstract:
A method of conditioning a subject in need of transplantation of progenitor cells in suspension of a tissue of interest is disclosed. The method comprising: (a) administering to a subject a therapeutically effective amount of an agent capable of inducing damage to the tissue of interest, wherein the damage results in proliferation of resident stem cells in the tissue; and subsequently (b) subjecting the subject to an agent which ablates the resident stem cells in the tissue. A method of transplanting progenitor cells in suspension of a tissue of interest to a subject in need thereof is also disclosed.
Abstract:
An isolated cytotoxic T-lymphocyte (CTL), said CTL being a tolerance inducing cell and substantially depleted of alloreactivity, and wherein said CTL does not comprise a central memory T-lymphocyte (Tcm) phenotype, the CTL being transduced to express a cell surface receptor comprising a T cell receptor signaling module, is disclosed. Methods of generating same and using same are also disclosed.
Abstract:
A method of treating a disease in a subject in need thereof is disclosed. The method comprising: (a) transplanting a non-syngeneic cell or tissue graft to the subject; and (b) administering to the subject a therapeutically effective amount of an isolated population of cells comprising non-graft versus host (GVHD) inducing anti-third party cells having a central memory T-lymphocyte (Tcm) phenotype, the cells being tolerance-inducing cells and capable of homing to the lymph nodes following transplantation, and further wherein the cells are either: (i) non-syngeneic with both the subject and the graft; or (ii) non-syngeneic with the graft and syngeneic with the subject, thereby treating the subject.
Abstract:
A method of generating an isolated population of cells comprising anti-third party cells having a central memory T-lymphocyte (Tcm) phenotype, the cells being tolerance-inducing cells and/or endowed with anti-disease activity, and capable of homing to the lymph nodes following transplantation is disclosed. The method comprising: (a) contacting peripheral blood mononuclear cells (PBMC) with a third party antigen or antigens in the presence of IL-21 so as to allow enrichment of antigen reactive cells; and (b) culturing the cells resulting from step (a) in the presence of IL-21, IL-15 and IL-7 in an antigen free environment so as to allow proliferation of cells comprising the central memory T-lymphocyte (Tcm) phenotype.
Abstract:
A method of treating or preventing a T cell mediated autoimmune disease in a subject in need thereof is disclosed. The method comprising: (a) transplanting immature hematopoietic cells into the subject; and (b) administering to the subject a therapeutically effective amount of an isolated population of non-GVHD inducing anti-third party cells comprising cells having a central memory T-lymphocyte (Tcm) phenotype, the cells being tolerance inducing cells and capable of homing to the lymph nodes following transplantation.
