Regulation of neuronal plasticity – integration of synaptic signaling pathways

Project

Regulation of neuronal plasticity – integration of synaptic signaling pathways

Project Details

Neuronal plasticity is fundamental to nervous system development and function. We have recently discovered that reactive oxygen species (ROS), known for their destructive capacity in the ageing or diseased brain, function as second messengers for implementing structural plasticity at synaptic terminals. Moreover, different sources of ROS (cytoplasmic vs mitochondrially generated) regulate genetically distinct aspects of synapse development (growth vs release site number). Do ROS sculpt synapse plasticity in response to the metabolic state of neurons? How does ROS signaling intersect with other signaling pathways regulating synaptic plasticity, such as BMP and Wnt? This project will combine biochemical and genetic approaches with electrophysiology and methods for live and super-resolution imaging to investigate the contribution of various signaling pathways to synapse plasticity. We expect this project to redefine our understanding of how multiple signaling pathways integrate at the synapse to regulate distinct elements of plasticity.
