Approaches used extensively in the Burton laboratory include: generation and characterization of novel transgenic and gene knockout zebrafish models to study the neurobiology of disease in vivo; development and deployment of automated high throughput neurobehavioral and imaging assays for unbiased phenotype-based chemical biology approaches; use of intravital imaging, novel chemoptogenetic systems and electrophysiological recordings to understand pathophysiological mechanisms in CNS neurons in vivo. Current areas of focus include:
Exploiting the optical transparency of zebrafish in order to allow live imaging in vivo of changes in neuronal mitochondrial function during the pathogenesis of synuclein and tau models.
Investigating the role of mitochondrial-telomeric ROS flux using novel transgenic zebrafish expressing chemoptogenetic sensitizers at different subcellular locations
Utilizing medium-throughput reverse genetics in zebrafish to determine the role of genes near risk-associated SNPs identified by GWAS studies in Parkinson’s disease and progressive supranuclear palsy
Unbiased phenotype-driven chemical modifier screens in zebrafish synuclein and tau models to discover novel molecular modulators and their targets
Using electrophysiological methods to understand how neuronal signaling is altered early in the pathophysiology of synuclein and tau models
