JANUARY 2013  Zebrafish are helping us confirm that pesticides are bad news for fish, farmers, and our group of PSW females. This freshwater fish is commonly used in research because it is easy to manipulate genetically, it develops rapidly and it is transparent, making the observation and measurement of biological processes much easier. By using a fluorescent dye and counting the neurons, researchers discovered a significant neuron loss only to the dopaminergic neurons in the fish that were exposed to pesticides. The other neurons were left unaffected. Thanks to the National Institute of Environmental Health Sciences who funded in part, this research at UCLA. Jeff Bronstein, Director of the UCLA Movement Disorders Program, is senior author of the study and a professor of neurology at UCLA. Read about his team including the link between pesticides and Parkinson’s Disease.
