Double Negative T Cells. We will summarize the most recent views on their origin at the thymic and peripheral levels as well as their tissue localization in immune and non-lymphoid organs. Injection of DNTs from healthy donors has been demonstrated to be effective against AML cells. Using a flow cytometry-based in vitro killing assay we demonstrated that the allogeneic DNTs expanded from healthy volunteers were cytotoxic against 2329. The earliest developing thymocytes lack the expression of the co-receptors CD4 and.

Using a flow cytometry-based in vitro killing assay we demonstrated that the allogeneic DNTs expanded from healthy volunteers were cytotoxic against 2329. This is an uncommon peripheral T-cell lymphoma that often presents with marked lymphocytosis hepatosplenomegaly and lymphoadenopathy. In preclinical transplantation models adoptive transfer of DN T-cells specifically inhibits alloreactive T-cells and prevents transplant rejection or graft-vs-host disease GvHD. Thats why were still double negative. The artificial expression of the transgenic αβTCR at the double negative stage of T cell development has been proposed to mimic signals normally conveyed by the γδTCR and thus lead to the generation of an artificial subpopulation of T cells with a unique profile of surface markers and cytokine production. For instance an increased number of DN T cells has been observed in many TCR transgenic models Hillhouse and Lesage 2012.

Double negative T cells have not only been observed in quad-deficient mice.

Absolute values of HLA-DR double negative DN T cells were significantly lower in the group of responders at one year and interaction between the timings were found in three T cell subsets T CD4 T CD8 and naïve T CD8 cells with the responders tending to present with lower absolute values and little inter-timing variation. For instance an increased number of DN T cells has been observed in many TCR transgenic models Hillhouse and Lesage 2012. Double negative T cells have not only been observed in quad-deficient mice. Previously we demonstrated that ex vivo expanded allo- genic DNTs represent a promising cellular therapy for the treatment of acute myeloid leukemia AML 1315. In preclinical transplantation models adoptive transfer of DN T-cells specifically inhibits alloreactive T-cells and prevents transplant rejection or graft-vs-host disease GvHD. Double negative T cells DNTs comprise 35 of the peripheral blood mature T lymphocyte pool as defined by expression of CD3 in the absence of CD4 and CD8.
