DORSAL ROOT GANGLION DEVELOPMENT - ANALYSIS OF SOX10 FUNCTIO N USING NOVEL TRANSGENIC AND MUTANT RESOURCES IN ZEBRAFISH

Project: Research council

Description

In normal development it is vital that cells make decisions about what type of cell to become. The peripheral nervous system consists of a series of clusters of cells (ganglia). These clusters contain cells of two types, neurons, and support cells (glia). To function correctly the ganglia must have appropriate numbers of both neurons and glia. Thus, cells must be allocated to each of these cell-types in the appropriate numbers. For one set of ganglia, the sensory ganglia, we know of several influences of cell fate. One is a protein that controls the activity of many genes - the set of genes that are activated determine whether that cell will be a neuron or a glial cell. The other is a set of proteins that mediate communication between adjacent cells, allowing co-ordination of their fate choices. Understanding how cells of developing ganglia co-ordinate these two influences is a key problem in understanding normal development. We have recently isolated a unique mutant in the former protein that appears to result in a defect in the function of the second system. Our proposal would allow us to test our ideas of how these influences are co-ordinated to generate ganglia.
