Abstract: The present invention relates to the field of fibrosis and inflammation and more particularly to the use of ADAM12 (A Disintegrin and Metalloproteinase 12) inhibitors to prevent or treat inflammation-induced fibrosis. The present invention also relates to the use of ADAM12 as a marker for inflammation-induced fibrosis and to the ablation of ADAM12 expressing cells as therapeutic approach to interfere with the development of pro-fibrotic cells.
Abstract: The present invention provides kits and assay methods for the early detection of pathogens, precise identification of the etiologic agent, and improved disease surveillance. More specifically, the present invention discloses an immunoassay leading to the rapid and simultaneous detection of antibodies to a wide range of infectious pathogens in biological fluids of infected patients. This immunoassay involves the covalent and oriented coupling of fusion proteins comprising an AGT enzyme and a viral antigen on an identifiable solid support (e.g. fluorescent microspheres), said support being previously coated with an AGT substrate. This coupling is mediated by the irreversible reaction of the AGT enzyme on its substrate. The thus obtained antigen-coupled microspheres show enhanced capture of specific antibodies as compared to antigen-coupled microspheres produced by standard amine coupling procedures.

Abstract: The invention relates to an in vitro method for prognosis, diagnosis or determination of the evolution of a condition involving an altered production of Basic Proline-rich Lacrimal Protein (BPLP) or of any of its maturation products, by detecting, or quantifying in a biological sample of a test subject, a BPLP protein or a maturation product thereof, and comparing the production of BPLP protein or maturation product with the production of the same in a biological sample of a control subject.

Abstract: The invention relates to mutant CyaA/E570Q+K860 polypeptides suitable for use as proteinaceous vectors for delivering one or more molecules of interest into a cell, in particular into a cell expressing the CD11b receptor. The invention further relates to polypeptide derivatives suitable for eliciting an immune response in a host. The invention is more particularly directed to polypeptides derived from an adenylate cyclase protein (CyaA) either under the form of a toxin or of a toxoid, which are mutant polypeptides. The mutant polypeptides are capable of retaining the binding activity of native CyaA to a target cell and preferably of also retaining the translocating activity of native CyaA through its N-terminal domain into target cells and furthermore have a pore-forming activity which is reduced or suppressed as compared to that of the native CyaA toxin.

Abstract: A method for the treatment and/or the prevention of a disease or a symptom related to dysfunction of regulatory T cell immunomodulation includes administering to a subject in need thereof compositions that regulate regulatory T cell immunomodulatory function, in which the compositions may be prepared by contacting starting materials with phosphorylation pathway-related factors, the agonists or the antagonists thereof. The phosphorylation pathway-related factors are selected from: proto-oncogene protein PIM1 and the coding sequence thereof. The regulation is achieved by regulating the activity of regulators of regulatory T cells selected from the group: FOXP3, IL-2, GITR, CTLA4, and a combination thereof.

Abstract: A method of assembling a sequence representing pieces of at least one chromosome from a set of raw sub-sequences representing DNA fragments of a library including DNA fragments including chains of contiguous nucleotides and including DNA fragments including combinations of at least two chains of contiguous nucleotides. After having obtained first values representing contact frequencies between DNA regions, the first values being associated with second values representing distances between the corresponding DNA regions, the method includes: updating a genome structure based on the first and second values and based on a theoretical model associating a contact probability between DNA regions with a distance between the corresponding DNA regions, the updated genome structure being representative of the real genome structure of the chromosome; and updating parameters of the theoretical model as a function of the updated genome structure.
