Human Tc1 and Tc2/Tc0 CD8 T-cell clones display distinct cell surface and functional phenotypes.
It has recently become clear that distinct subsets of CD8 T cells, analogous to their CD4 counterparts, exist in rodents and humans. To examine functional differences between human CD8 T-cell subsets, we generated Tc1, Tc2, and Tc0 T-cell clones from the peripheral blood of healthy individuals. The majority of CD8 T-cell clones generated displayed a classic Tc1 phenotype, but 10% to 20% secrete...
متن کاملNon-host-reactive donor CD8+ T cells of Tc2 phenotype potently inhibit marrow graft rejection.
Donor CD8+ T cells capable of host reactivity inhibit marrow graft rejection, but also generate graft-versus-host disease (GVHD). To evaluate whether the Tc1- and Tc2-type subsets of CD8 cells might inhibit rejection without host reactivity, we established an F1 into-parent murine bone marrow transplant model. Donor Tc1 and Tc2 cells were generated that preferentially secreted type I or type II...
متن کاملIL-17 and IL-4 Producing CD8+ T Cells in Tumor Draining Lymph Nodes of Breast Cancer Patients: Positive Association with Tumor Progression
Background: CD8+ cytotoxic T lymphocytes have been recently divided based on their cytokine expression profile. Objective: To evaluate the percentages of CD8+ lymphocytes and their effector subsets including Tc1, Tc2 and Tc17 in the tumor draining lymph nodes (TDLNs) of patients with breast cancer. Methods: Single cell suspensions were obtained from TDLNs of 42 patients with breast cancer. Stai...
متن کاملUnique phenotype of human tonsillar and in vitro-induced FOXP3+CD8+ T cells.
Forkhead box p3 (FOXP3) is known to program the acquisition of suppressive capacities in CD4(+) regulatory T cells (Treg), whereas its role in CD8(+) T cells is unknown. The current study investigates whether FOXP3 also acts as a Treg master switch in peripheral blood and tonsillar CD8(+) T cells. Single-cell analyses reveal the existence of a FOXP3(+)CD8(+) population in human tonsils, whereas...
