摘要:
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.

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.
摘要:
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.
摘要:
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.
摘要:
A method of treating a pulmonary disorder or injury in a subject in need thereof is disclosed. The method comprising administering to the subject non-syngeneic pulmonary tissue cells in suspension comprising an effective amount of hematopoietic precursor cells (HPCs) or supplemented with HPCs, wherein the effective amount is a sufficient amount to achieve tolerance to the pulmonary tissue cells in the absence of chronic immunosuppressive regimen. A method of inducing donor specific tolerance in a subject in need of a pulmonary cell or tissue transplantation is also disclosed.
摘要:
A method of treating a subject in need of a non-syngeneic cell or tissue graft is disclosed. The method comprising: (a) transplanting into a subject a dose of T cell depleted immature hematopoietic cells, wherein the T cell depleted immature hematopoietic cells comprise less than 5 x 105 CD3+ T cells per kilogram body weight of the subject, and wherein the dose comprises at least about 5 x 106 CD34+ cells per kilogram body weight of the subject; and subsequently (b) administering to the subject a therapeutically effective amount of cyclophosphamide, wherein the therapeutically effective amount comprises 25-200 mg per kilogram body weight, thereby treating the subject.

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.
摘要:
A method of treating a subject in need of a cell or tissue transplant is disclosed. The method comprising (a) transplanting a non-syngeneic cell or tissue transplant into the subject, wherein the transplant comprises bone marrow or lymphoid cells; and (b) administering to the subject a therapeutically effective amount of an immunosuppressive regimen comprising a Sphingosine 1-Phosphate Receptor Agonist, a B7 molecule inhibitor and a CD2/CD58 pathway inhibitor, thereby treating the subject.
