PURPOSE T cells constitutively expressing both CD4 and CD25are essential for maintenance of self-tolerance and therefore have been referred to as regulatory T cells (Treg). Experimental tumor models in mice revealed that Tregs are potent inhibitors of an antitumor immune response. The current study was designed to determine whether cancer patients exhibit(More)
T cells seem to be responsible for liver damage in any type of acute hepatitis. Nevertheless, the importance of Kupffer cells (KCs) for T-cell-dependent liver failure is unclear. Here we focus on the role of KCs and tumor necrosis factor (TNF) production after T cell stimulation in mice. T-cell- and TNF-dependent liver injury were induced either by(More)
During HIV/SIV infection, there is widespread programmed cell death in infected and, perhaps more importantly, uninfected cells. Much of this apoptosis is mediated by Fas-Fas ligand (FasL) interactions. Previously we demonstrated in macaques that induction of FasL expression and apoptotic cell death of both CD4(+) and CD8(+) T cells by SIV is dependent on a(More)
There is increasing evidence that the adipose tissue and immunologic processes are closely linked. The most abundant protein within the adipocyte is adiponectin. Our current work reports that adiponectin has potent immuno-suppressive properties, as it induces the production of the anti-inflammatory mediators IL-10 and IL-1RA in primary human monocytes,(More)
Recent studies have demonstrated cyclooxygenase 2 (COX-2) overexpression in various human malignancies, especially in breast cancer, where COX-2 turned out to be a predictor of poor survival. To evaluate the relation of COX-2 and Ep-CAM overexpression and its prognostic significance, we performed a retrospective study on 212 breast cancer patients with a(More)
Both mast cells (MCs) and regulatory T cells (Tregs) have gained attention as immunosuppressive cell populations. To investigate a possible interaction, we used the Th1- and Th17-dependent model of nephrotoxic serum nephritis (NTS), in which both MCs and Tregs have been shown to play a protective role. Transfer of wild-type (wt) Tregs into wt recipients(More)
To define the role of quantitative graft composition and donor killer-cell immunoglobulin-like receptor (KIR) genotype in clinical outcome following unmanipulated peripheral blood stem cell transplantation (PBSCT) from human leucocyte antigen (HLA)-identical siblings, 43 consecutive transplants for haematological malignancies were analysed retrospectively.(More)
CD4+CD25+ regulatory T cells (Treg) are of critical importance for the maintenance of tolerance. The kidney is frequently involved in autoimmune diseases, such as lupus erythematosus or glomerulonephritis (GN). Therefore, the therapeutic efficacy of Treg in a T cell-dependent murine model of experimental anti-glomerular basement membrane (anti-GBM) GN was(More)
TNF-alpha has been clearly identified as central mediator of T cell activation-induced acute hepatic injury in mice, e.g., Con A hepatitis. In this model, liver injury depends on both TNFRs, i.e., the 55-kDa TNFR1 as well as the 75-kDa TNFR2. We show in this report that the hepatic TNFRs are not transcriptionally regulated, but are regulated by receptor(More)
RATIONALE The neuropeptide catestatin is an endogenous nicotinic cholinergic antagonist that acts as a pleiotropic hormone. OBJECTIVE Catestatin shares several functions with angiogenic factors. We therefore reasoned that catestatin induces growth of new blood vessels. METHODS AND RESULTS Catestatin induced migration, proliferation, and antiapoptosis in(More)
