My colleagues and I are interested in understanding how cell fate is determined during neuronal development in Drosophila . In recent years we have focused on a group of genes, called "neurogenic genes", which have been shown to interact in a common pathway to determine the fate of virtually every cell type in many complex organisms. A second area of research is to understand the molecular basis of neurotransmitter release. Using genetic and molecular approaches we have identified and characterized the function of the NSF gene which plays a central role in this process. Finally, we are also developing Drosophila models of aging and neurodegenerative disease. This work involves the analysis of SOD and presenilins for which mutations have been implicated in Amyotrophic Lateral Sclerosis and Alzheimers Disease, respectively.
Future Research Interests
- Genetic screens to identify other members of the neurogenic pathway.
- Characterization of mammalian homologues of these genes.
- Analysis of the function of presenilins in normal development and disease.
- Characterization of novel regulators of neurotransmitter release/secretion.
- Canadian Institutes of Health Research
