Description du projet
Concevoir des vésicules dynamiques avec un cytosquelette artificiel
Les vésicules sont entourées par une bicouche de lipides et servent de modèles artificiels de membranes cellulaires. Les scientifiques du projet SHINEShift, financé par l’UE, entendent transformer les vésicules en structures dynamiques capables de répondre aux stimuli extérieurs et de résister à la pression mécanique. À cette fin, ils utiliseront la chimie synthétique pour développer un cytosquelette artificiel à l’intérieur des vésicules qui consiste en tubules à base de peptides. Ces tubules se formeront et se développeront en réponse à la lumière, étendant ainsi les applications potentielles des vésicules artificielles. En outre, les méthodologies générées peuvent être utilisées dans d’autres domaines, comme la biologie synthétique et la science des matériaux.
Objectif
The most commonly used artificial cell membrane models are vesicles. However, these static structures, consisting of a lipid bilayer surrounding a fluid, are poor in resisting mechanical stress. Enhancing their mechanical properties with a dynamic artificial cytoskeleton will both allow stabilizing their shape and transforming these passive objects into dynamic stimuli-responsive systems. In this MSCA project photo-responsive synthetic supramolecular tubules will be used as an artificial cytoskeleton inside vesicles. My aim is to develop stiff and at the same time responsive tubules based on cyclic peptide design that can grow and generate pushing forces during the fueling step, and disassemble when the fuel stops, both in a fully reversible manner. This cutting edge interdisciplinary project brings together several disciplines in chemistry, i.e. organic synthesis and supramolecular chemistry with colloidal chemistry (and/or microfluidics), and its scientific impact will spread through various fields – from supramolecular chemistry to material science (leap from static vesicles to dynamic ones), and synthetic biology (relevance for future applications in the field of artificial cells). My expertise as experienced researcher in the field of organic synthesis will be applied to the field of dynamic supramolecular systems based on photo-switchable compounds in which the host (Dr. Kudernac) has made notable recent progress. During this training-through-research project I will be able to learn the preparation processes for the vesicles and microscopy techniques that are fundamental for investigating (dynamic) supramolecular assemblies and which will further expand my horizontal skills. In addition, training activities during this fellowship will strongly enhance my leadership and transferable skills. Hence, the Fellowship will allow me to become a distinctive researcher in a highly competitive scientific environment.
