7- Neuronal Cell Adhesion and Migration

Research Themes

Neural development proceeds through proliferation and migration of neuronal precursors, their organization in layers and nuclei, then their morphological differentiation leading to the wiring of functional structures. Identifying molecular and cellular mechanisms supporting these developmental processes is important for a better understanding of both the normal brain development and the physiopathology of diseases associated to abnormal neuron positioning or wiring.

The general aim of our team is to understand how the coordinated regulation of cell adhesion, actin dynamics and microtubules arrangement contributes to the migration of neuronal cells. On one hand, the group of RM. MEGE is focusing on the role of signaling cascade activated by cadherin engagement on the control of neuronal cell migration and survival; on the other hand the group of C. METIN is studying the cellular and molecular mechanisms controlling the motility and polarization of cortical interneurons migration.

The RM MEGE group is asking how cadherin adhesion receptors can inform cells about their environment and transmit an adhesion signal allowing controlled cell responses in term of migration, differentiation and survival. Thanks to the development of original strategies based on the use of biomimetic adhesive surfaces activating cadherin and mimicking cell contacts in vitro, we have been able to describe the mechanisms and dynamics of cell-cell contact formation and the transduction of signals controlling cytoskeleton organization, cell cycle and gene expression. We have shown that the extension of neurites induced by cadherin results from the activation of classical biochemical signaling cascades as well as from the adhesion-triggered anchoring of these adhesion receptors to the actin tread-milling in growth cones allowing the transduction across the membrane of traction forces generated by the acto-myosin system.

We are focusing now on the molecular mechanisms responsible of these biochemical and mechanical signal transductions using various cell biology, cellular imaging and biochemical approaches; as well as the physiological consequences of the transduction of the adhesion signal on the migration and polarization of migrating neuronal precursors (in collaboration with C. METIN).

The C METIN group has characterized the migration cycle of future cortical interneurons born in medial ganglionic eminence (MGE). During migration, these neurons exhibit spectacular morphological transformations illustrated by scheme below. By combining live cell imaging and transmission electronic microscopy, we have shown that the migration cycle of these neurons comprises two alternating phases : a forward movement of the centrosome / Golgi apparatus complex at a distance from the nucleus followed by a translocation of the nucleus toward this complex. Nucleokinesis phases are correlated to specific changes in the branched neuritic arbor. In addition, we have shown that the nuclear translocation toward the centrosome requires acto-myosin (in green on scheme) contractility and that non muscle filaments accumulate behind the nucleus.

Our present studies are aimed at studying the organization of the microtubules array at ultrastructural level and at characterizing its changes during migration. We investigate the mechanisms controlling centrosome positioning in these neurons, and in collaboration with RM Mège, we are studying the role of cadherin mediated adhesion in the migratory behavior of MGE cells. Finally, we are studying how proteins mutated in mental retardation impair signalling pathways involved in MGE cell migration.
