Stephen J. Royle (Full Professor, Centre for Mechanochemical Cell Biology, University of Warwick, UK)

Keywords: membrane trafficking, image analysis, cell division

Thematic

Steve is interested in cell biology at the molecular level. His lab is focussed on understanding membrane traffic and mitosis primarily using quantitative imaging approaches. To investigate these processes, Steve's lab has developed a number of genetic tools, including "hot-wired endocytosis" which enables endocytosis to be triggered on-demand.

Franck Carreiras (Full Professor CY Cergy Paris University)

Key words : Cell Biology, Cell-Matrix interactions, Tumoral microenvironment

Thematic

His recruitment at Cergy Pontoise allowed him to set up within the University a long-lasting theme concerning the influence of the matrix microenvironment on the tumoral dissemination. Since his nomination as leader of the MEC-uP group he continues this work on the tumoral microenvironment and the metastatic dissemination while diversifying his projects according to the knowledge of each members of his group (cellular ageing, tissue repair, surfaces functionalization). The characterization of the matrix microenvironment and its regulating impact on cellular activities stays at the center of his research.

Olivier Gallet (Full Professor CY Cergy Paris University)

Key words : Cell adhesion proteins, ECM dynamics, Glycosylations, lectins, plant wall, biofunctionalization, cell adhesion, matrix engineering, Biological traces and forensic sciences, Cellular behaviour and adaptation to environmental parameters.


Thematic

I-Universality of cell adhesion proteins

Purification and characterization of matrix proteins (Fibronectin and vitronectin) in animal tissues and identification of homologues in plant walls. Study of the impact of glycosylations on the conformation of cell adhesion proteins and their recognition by animal and plant cells. Biofunctionalization of hybrid materials and studies of protein conformations onto the surface of materials alone or in interaction with cells

II- Characterization of multifunctional heterologous protein polymers

Role in immunity and adaptation to environmental stress. Study of the involvement of glycosylation sequences in the formation of protein polymers in association with lectins: Case of fibronectin and vitronectin interactions of blood plasma with circulating lectins (Mannose Binding proteins and Collectins).

III- Cellular behaviour –Biological traces and footprint of life- adaptation of life to environmental parameters

Study of the biological trace and its persistence in time in different mimetic environments of criminal scenes. Cellular behaviour on different interfaces. Research and discrimination of human cell trace markers.

Behaviour of plants and human cells submitted to the variations of the physicochemical parameters of the environment as surface chemical composition, biomolecular surfaces or intefaces, surface topography and sound environment.
