The present invention relates to a method of detection of the presence of at least one domain of interest on a macromolecule to test, wherein said method comprises the following steps:a) determining beforehand at least two target regions on the domain of interest, designing and obtaining corresponding labeled probes of each target region, named set of probe of the domain of interest, the position of these probes one compared to the others being chosen and forming the specific signature of said domain of interest on the macromolecule to test;b) after spreading of the macromolecule to test on which the probes obtained in step a) are bound, detection of the position one compared to the others of the probes bound on the linearized macromolecule, the detection of the signature of a domain of interest indicating the presence of said domain of interest on the macromolecule to test, and conversely the absence of detection of signature or part of signature of a domain of interest indicating the absence of said domain or part of said domain of interest on the macromolecule to test.

The application relates to Listerin monocytogenes, more particularly to the determination of the clone to which a L. monocytogenes isolate belongs. The means of the application involve primers and/or probes, more particularly multiplex primers. The means of the application are notably useful to assess the invasivity that said L. monocytogenes isolate might show in a human being.

The invention relates to the quantitation of specific antibodies for at least one redox form of High mobility group box 1 (HMGB1) contained in a biological sample, in particular human serum and/or CerebroSpinal Fluid (CSF). The invention also relates to an in vitro method for assessing the state of progression of a disease or a disorder in which HMGB1 is involved, to an in vitro method for the identification of predisposition, prognostic or diagnostic biomarkers of a disease or a disorder in which HMGB1 is involved. The invention also relates to a kit to quantitate said specific antibodies for at least one redox form of HMGB1, in particular human HMGB1.

The invention relates to a new method for generating a luminescent signal, which is based on an enzyme-independent photon emission mechanism (EiPE), whereby luminescent light is generated when a bioluminescent substrate interact with a physical surface in the absence of any catalytic enzyme. In particular embodiments, the method is used to stimulate light emission by fluorescent molecules. The invention relates also to kits for implementing a method according to the present invention and to the use of a bioluminescent substrate, in the presence of a physical surface, to produce a luminescent signal in the absence of enzymatic catalyst.

The present invention relates to the use of variable domains of camelid heavy-chain antibodies (VHH domains) directed against an intracellular target and having an isoelectric point of at least 8.5, for targeting said intracellular target or for the preparation of a peptide vector. Particularly, it concerns VHH domains directed against a glial fibrillary acidic protein and uses thereof for preparing therapeutic or diagnostic agents.

The present invention pertains to the field of protein engineering, and provides means for obtaining stable molecules that specifically bind to a target selected amongst a large variety of ligands families. In particular, the present invention provides methods for obtaining a molecule specifically binding to a target of interest, through a combinatorial mutation/selection approach with an OB-fold protein as a starting molecule. In particular, the target of interest can be of a different chemical nature form that of the native target of the OB-fold protein used as the starting molecule.

Migration is a polarized cellular process that opposes a protrusive front edge to a retracting trailing edge. From the front to the rear, actin-mediated forces sequentially promote cell protrusion, adhesion, contraction, and retraction. Over the past decade, microtubules have revealed their pivotal role in cell migration. Through their roles in cell mechanics, intracellular trafficking, and signaling, microtubules participate in all essential events leading to cell migration. The front-rear polarization of microtubule functions relies on the asymmetric regulation of microtubule dynamics and stability; the asymmetric distribution of microtubule-associated protein complexes; and finally, the orientation of the microtubule network along the axis of migration. Microtubule network polarity controls the establishment and maintenance of the spatial and temporal coordination of migration events and is therefore the key to persistent directed migration. This review summarizes our current understanding of the functions of microtubules in persistent cell migration and of the migration-associated signals that promote microtubule network polarization. © 2013 by Annual Reviews.
