MARCH1-mediated MHCII ubiquitination promotes dendritic cell selection of natural regulatory T cells
patients and methods in this cross-sectional study, peripheral mononuclear cells (pbmcs) were isolated from peripheral blood of 29 patients with newly diagnosed pulmonary tb and 19 patients with positive tuberculin skin test. the pbmcs were activated with ppd for 72 hours. activated cells were harvested, rna was extracted and cdna was synthesized. a real-time taqman method was designed and opti...
Depletion of T Regulatory Cells Promotes Natural Killer Cell–Mediated Cardiac Allograft Vasculopathy
Antigen specific T regulatory cells (Treg) are often CD4(+)CD25(+)FoxP3(+) T cells, with a phenotype similar to natural Treg (nTreg). It is assumed that nTreg cannot develop into an antigen specific Treg as repeated culture with IL-2 and a specific antigen does not increase the capacity or potency of nTreg to promote immune tolerance or suppress in vitro. This has led to an assumption that anti...
Thymus-derived, naturally occurring CD4(+)CD25(+)Foxp3(+) regulatory T cells (nTregs) and Tregs induced in the periphery (iTregs) have both been implicated in regulating immune responses. However, the relationship between these populations in the same host, and their relative contribution to the overall Treg pool, has not been examined. Using a tumor-induced T cell tolerance model, we find that...
