Rapamycin combined with TGF-β converts human invariant NKT cells into suppressive Foxp3+ regulatory cells.
Invariant NKT (iNKT) cells constitute a versatile T cell subset with important regulatory functions, which are thought to result essentially from their capacity to promptly produce cytokines that influence the Th1/Th2 balance. In this study, we report that these cells can also express Foxp3, an important transcriptional regulator associated with suppressive activity, once they have been exposed...

متن کاملNeutralization of IL-4 and IFN-γ Facilitates inducing TGF-β-induced CD4+Foxp3+ Regulatory Cells
It has been well recognized that TGF-β is able to induce CD4(+)CD25(+)Foxp3(+) suppressor/regulatory T (iTreg) cells and IL-2 facilitates iTreg induction and expansion, however, only half of TGF-β-induced CD4(+)CD25(+) cells express Foxp3 and remaining CD4(+)CD25(+)Foxp3- cells may represent effector cells. Whether other factor(s) can increase Foxp3 expression by CD4(+)CD25(+) cells induced wit...
متن کاملInduction of antigen-specific immune tolerance by TGF-beta-induced CD4+Foxp3+ regulatory T cells.
Like natural CD4(+)CD25(+) Treg cells, TGF-beta-induced Treg cells also prevent allograft rejection in MHC-mismatched organ transplantation models. In analyzing this effect with greater detail, we determined that injection of TGF-beta-induced, alloactivated CD4(+)CD25(+) cells induces antigen-specific immune tolerance in vivo. Increased CD4(+)CD25(+) cells in recipients contribute to this immun...
متن کاملNK, NKT and Invariant-NKT Cells in Tumor Draining Lymph Nodes of Patients with Breast Cancer
Background: NK (natural killer) and NKT (natural killer T) cells, as components of innate immune system, play a crucial role in tumor progression and dissemination. Objective: To investigate the percentages of NK cells, NKT cells, iNKT (invariant natural killer T) cells, total T lymphocytes as well as activated T lymphocytes, in tumor draining lymph nodes (TDLN...
