Molecular Mechanisms of Neuron Migrations

The 100 billion neurons that form our central nervous system (CNS) are exquisitely localized and wired, allowing us to perform everyday tasks such as walking, reading or thinking. Neurons find their positions within the brain almost exclusively during embryonic development. A wide variety of guidance cues pilot neurons from the proliferation niches to their final destination, where they stop, mature, and integrate into the existing network. Neurons respond to these guidance cues by regulating signaling pathways that control a myriad of cellular processes (including neuronal speed, direction, and rest phases). The goal of our research is to understand how migrating neurons integrate guidance information by regulating signaling pathways to navigate and successfully reach their final destinations. We are currently investigating 1) molecular mechanisms that control neuronal positioning in the neocortex, 2) the role of the E3 ubiquitin ligase Cullin-5 during Purkinje cell migration, and 3) the evolution of neuronal progenitor competence during CNS development.
