Vesicular trafic and receptors dynamics in epithelial and neuronal cells.

In brief:
We are working ont the trafic of membranous molecules and vesicular traffic. membrane fusion between a vesicle and a target compartment is achieved by SNARE proteins (Soluble N-ethylmaleimide sensitive fusion protein (NSF) Attachment protein Receptor).


SNAREs are classifed in 2 types : the v-SNAREs on the vesicles (v- for vesicles) and the t-SNAREs on the target compartment (t- for target). The v-SNAREs and t-SNAREs form complexes which bring closer the two membranes and favors the fusion. We are working on the role of SNARE proteins in the traffic of adhesion molecules and receptors both at the synapse in neuronal cells and in epithelial cells.

We have worked on membrane traffic in different physiological contexts:
