Two methods to generate human dendritic cells from hematopoietic precursor cells in peripheral blood have recently been published. One approach utilizes the rare CD34+ precursors and GM-CSF plus TNF-alpha. The other method makes use of the more abundant CD34- precursor population and GM-CSF plus IL-4. Here we report a method that is based on the latter(More)
Skin dendritic cells (DC) express C-type lectin receptors for the recognition of pathogens. Langerhans cells (LC) express the receptor Langerin/CD207, whereas DEC-205/CD205 is mainly expressed by dermal DC, but can also be detected at low levels on LC. In this study, we tested an ex vivo approach for targeting DC in situ with monoclonal antibodies (mAb)(More)
Increased neopterin concentrations in body fluids are found in diseases associated with activated, cell-mediated immunity including infections, autoimmune diseases, and certain malignancies. Monocytes/macrophages are known to secrete large amounts of neopterin upon stimulation with interferon-gamma (IFN-gamma). Ontogenetically, the major part of dendritic(More)
Progress in dendritic cell research has been overwhelming in the past few years. This was made possible by the recent development of simple methods to generate large numbers of dendritic cells. These methods use as starting populations for culture either CD34+ progenitor cells from cord blood or bone marrow, or monocytes from peripheral blood. The latter(More)
Dendritic cells produce IL-12 both in response to microbial stimuli and to T cells, and can thus skew T cell reactivity toward a Th1 pattern. We investigated the capacity of dendritic cells to elaborate IL-12 with special regard to their state of maturation, different maturation stimuli, and its regulation by Th1/Th2-influencing cytokines. Monocyte-derived(More)
BACKGROUND IL-12 is a crucial factor in the development and course of allergic diseases. By virtue of their IL-12 production, dendritic cells (DCs) are potent inducers of T(H)1 responses. However, distinct subsets of DCs have also been shown to induce T(H)2 differentiation. OBJECTIVE We hypothesized that DCs from atopic and nonatopic individuals might(More)
OBJECTIVE To investigate the efficacy of the endothelin receptor antagonist, bosentan, in patients with RP secondary to SSc without pre-existing digital ulcers. METHODS Single-centre, randomized, prospective, double-blinded comparison of bosentan and placebo. Patients received either 62.5 mg bosentan twice daily for 4 weeks, followed by 125 mg twice daily(More)
Murine tumor models that closely reflect human diseases are important tools to investigate carcinogenesis and tumor immunity. The transgenic (tg) mouse strain tg(Grm1)EPv develops spontaneous melanoma due to ectopic overexpression of the metabotropic glutamate receptor 1 (Grm1) in melanocytes. In the present study, we characterized the immune status and(More)
