Prof Peter Brophy
Molecular and Cell Biology of Axon-Glia Interactions in Health and Disease
Centre for Neuroregeneration University of Edinburgh

Research Area

The goal of the Brophy laboratory is to understand how interactions between neurons and glia underpin rapid nerve impulse conduction in the vertebrate nervous system. Myelination of axons is a key event that stimulates the clustering of voltage gated sodium channels at nodes of Ranvier. The concentration of these sodium channels with associated proteins at nodes promotes rapid propagation of the action potential. A second key axonal domain is the axon initial segment (AIS). It has been assumed that the AIS initiates the action potential.

We are addressing three main questions:
1. What determines the site of node of Ranvier assembly?
2. How are voltage-gated sodium channels clustered at the node?
3. What is the role of the axon initial segment?
