PURPOSE Malignant mesothelioma is a highly aggressive tumor and is often diagnosed too late for a curative treatment. We compared diagnostic and prognostic values of mesothelin and osteopontin in 172 patients suspected of malignant pleural mesothelioma (MPM) and in a control group of 112 asymptomatic asbestos-exposed subjects. EXPERIMENTAL DESIGN(More)
Heme oxygenase-1 (HO-1) is an intracellular enzyme that degrades heme and inhibits immune responses and inflammation in vivo. In most cell types, HO-1 is inducible by inflammatory stimuli and oxidative stress. Here we demonstrate that human monocyte-derived immature dendritic cells (iDCs) and several but not all freshly isolated rat splenic DC subsets and(More)
MUC1 glycoprotein is often found overexpressed and hypoglycosylated in tumor cells from numerous cancer types. Since its discovery MUC1 has been an attractive target for antitumor immunotherapy. Indeed, in vitro and in vivo experiments have shown T-cell-specific responses against MUC1 in an HLA-restricted and HLA-unrestricted manner, although some animal(More)
PURPOSE Plasmacytoid dendritic cells (pDC) are antigen-presenting cells specialized in antiviral response. The measles virus vaccine is proposed as an antitumor agent to target and specifically kill tumor cells without infecting healthy cells. EXPERIMENTAL DESIGN Here, we investigated, in vitro, the effects of measles virus vaccine-infected tumor cells on(More)
Despite conventional medical and surgical treatments, malignant pleural mesothelioma (MPM) remains incurable. Oncovirotherapy (i.e., the use of replication-competent virus for cancer treatment) is currently explored in clinical trials. In this study, we investigated the antineoplastic potential of a new oncolytic viral agent, a live-attenuated measles virus(More)
UNLABELLED We assessed comparatively the diagnostic value of two potential malignant pleural mesothelioma (MPM) markers: hyaluronic acid (HA) and soluble mesothelin. MATERIALS AND METHOD We measured serum and pleural fluid values of mesothelin and hyaluronic acid in 76 patients with MPM, 33 patients with pleural metastases of carcinomas (Mets group) and(More)
Dendritic cell (DC) maturation is the process by which immature DC in the periphery differentiate into fully competent antigen-presenting cells that initiate the T cell response. However, DC respond to many distinct maturation stimuli, and different types of mature DC induce qualitatively different T cell responses. As DC maturation involves the coordinated(More)
Acute myeloid leukemias (AMLs) are monoclonal proliferations of undifferentiated myeloid progenitors in blood and bone marrow. Long-term remissions are achieved in <50% of patients. There is hope that activation of specific antileukemic immune responses could efficiently eliminate minimal residual disease at the end of chemotherapy and decrease the(More)
Confronted with the inadequacy of traditional charts, we tested the contribution of Treemaps to the representation of medical data. Treemap charts allow description of large hierarchical collections of quantitative data, on a synthetic way. Treemaps were implemented using PHP5, and were tested in the field of DRG-mining and other medical informations. From(More)
