Sébastien Boutry, Dr Sc, En charge des manipulations d'IRM et d'imagerie optique / in vivo (Umons)
sebastien.boutry@umh.ac.be

Sébastien Boutry was born in 1978 and studied at the University of Mons (UMons) from which he graduated with a M.Sc. Degree (Biology) in 2001. He became a researcher in the nuclear magnetic resonance (NMR) and molecular imaging laboratory of Prof. Robert N. Muller (UMons). Using the magnetic resonance imaging (MRI) technique as a tool for biological studies, he first focused on MRI contrast agents (gadolinium-based as well as iron oxide-based) specific for molecular markers of inflammation, developed in the laboratory (six papers were published). He obtained his Ph.D. in Biology in 2007. During his thesis, he performed and published several studies on the magnetic labelling of cells with iron oxide-based nanoparticular MRI contrast agents. He also attempted to use specifically vectorized nanoparticles as tools for the tracing of brain neurons in the context of an Interuniversity Attraction Poles program. This specific cellular targeting aspect was also approached in a work he started as a “FNRS – Télévie” scientific collaborator in 2006, aiming at the development of a specifically targeted contrast agent which might allow for the MRI monitoring of the efficiency of pro-apoptotic drugs used for anti-cancer therapies. In 2008, he became a research collaborator in the Center for Microscopy and Molecular Imaging (CMMI). He is developing biological applications of NMR (MRI and MR spectroscopy), but also other techniques of molecular imaging such as optical imaging and nuclear medicine.

Mathieu Roch, Bach Elect. (Umons)
mathieu.roch@umons.ac.be

Mathieu Roch was born in 1983. He studied at the “Roi Baudoin” High School (Mons) from which he graduated with a B.Sc. Degree (Electronics) in 2004. For 4 years, he worked in the electronic development of traffic radars for the Belgian society SIRIEN. In 2009, he joined the Center for Microscopy and Molecular Imaging (CMMI) as a technical collaborator responsible for the maintenance of NMR equipments and for the running of MRI and optical imaging experiments.

Lionel LARBANOIX, Dr Sc
lionel.larbanoix@umons.ac.be

Lionel Larbanoix: born in August, 1982 in Uccle (Belgium), he obtained his Master degree in biology in 2005 from the University of Mons, Belgium. He obtained his Ph.D. in Biomedical Sciences in 2010 from the same university. His Ph.D. thesis was focused on the magnetic resonance imaging (MRI) of Alzheimer’s disease. He screened peptide libraries by using the phage display technology in order to find specific ligands of amyloid deposits. These ligands were then grafted on MR contrast agents to allow in vivo visualisation of amyloid plaques (results published in Neurobiology of Aging in 2008). He worked for two years in the DIAPATH unit within The Center for Microscopy and Molecular Imaging (CMMI). His activity was focused on the development of immunohistochemistry protocols and on the identification, characterization and validation of protein biomarkers. He is now a collaborator in the MRI and Optical Imaging units within the CMMI. His activity is focused on the development of biological applications of optical imaging and MRI.

Descriptif et applications

L’IRM est basée sur le principe de la résonance magnétique nucléaire, permise par l’alignement des moments magnétiques d’atomes placés dans un champ magnétique. Cette technique qui est aujourd’hui devenue un des meilleurs outils de la radiologie clinique est aussi largement utilisée en recherche en raison de ses extraordinaires possibilités. Les images sont obtenues in vivo avec une très haute résolution spatio-temporelle. Leur qualité et leur contenu peuvent être augmentés par l’administration d’agents de contraste spécifiques qui permettront, par exemple, une détection plus efficace des tumeurs ou de leurs métastases. L’IRM peut aussi être utilisée dans le contexte d’autres applications biomédicales comme l’angiographie (imagerie des vaisseaux sanguins), l’imagerie « fonctionnelle » (activation de zones du cerveau par exemple), l’imagerie et la spectroscopie cellulaires et moléculaires (imagerie et analyse biochimique simultanée d’un type cellulaire particulier ou d’une molécule spécifique).

Le développement de traceurs spécifiques est mené en collaboration avec le Service de Chimie Générale, Organique et Biomédicale de l’Université de Mons(http://portail.umons.ac.be/fr/universite/facultes/fmp/services/service1/pages/default.aspx)
