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 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.
