Abstract: 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.

Abstract: A method of transplantation is disclosed. The method comprising administering to a subject in need of transplantation of cells in suspension, a therapeutically effective amount of tolerance inducing anti-third party cytotoxic T-lymphocytes (CTLs), wherein the tolerance inducing anti-third party CTLs are generated by directing T-lymphocytes of a donor against a third party antigen or antigens, the tolerance inducing anti-third party CTLs being substantially depleted of T-lymphocytes capable of developing into alloreactive CTLs, and wherein the tolerance inducing anti-third party CTLs do not comprise cells having a central memory T-lymphocyte (Tcm) phenotype, wherein the cells in suspension comprise non-hematopoietic cells or hematopoietic cells which are not stem cells. Methods of treating and kits are also provided.

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: An isolated population of cells comprising non-GVHD inducing anti-third party cells having a central memory T-lymphocyte (Tcm) phenotype is provided. The cells being tolerance-inducing cells and capable of homing to the lymph nodes following transplantation. Methods of generating same, use of same and methods of treatment are also provided.

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 treating a subject in need of a non-syngeneic cell or tissue graft is disclosed. The methos comprising: (a) transplanting into a subject a dose of T cell depleted immature hematopoetic cells, wherein the T cell depleted immature hematopoetic cells comprise less than 5×105 CD3+ T cells per kilogram body weight of the subject, and wherein the dose comprises at least about 5×106 CD34+ cells per kilogram body weight of the subject, and wherein the T cell depleted immature hematopoetic cells are obtained by separating the T cells from the immature hematopoetic cells by magnetic cell sorting, and (b) administering to the subject a therapeutically effective amount of cyclophosphamide, wherein the therapeutically effective amount comprises 25-200 mg per body weight, thereby treating the subject.

Abstract: 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.
