Research Interest:

Synaptic Targets of Oxidative Stress in Neurodegenerative Disorders

The overall focus of the Watson lab is to understand how synaptic function is altered in the age-related disorders Parkinson's Disease (PD) and Huntington's Disease. Experimental paradigms consist of molecular/biochemical and electrophysiological studies of synaptic function in vitro in mouse brain slices. Synaptic plasticity approaches include high frequency-induced long-term depression (LTD) and long-term potentiation (LTP) as well chemically induced LTP (chemLTP). A major goal of the lab is to determine the role of human alpha-synuclein in presynaptic plasticity and related cell signaling pathways in the corticostriatal circuit in a variety of transgenic mouse models for PD. A second goal is to identify the relevant mitochondrial targets of oxidative stress induced by pesticides and herbicides as well as alpha-synuclein. A third goal is to apply new proteomic approaches to full-length amino acid sequencing of neurological disease-related proteins such as alpha-synuclein in micro-amounts of brain tissue.

Bio:

Dr. Watson received his Ph.D from the Department of Chemistry and Biochemistry at UCLA in 1985 in Jay Gralla's Laboratory in which he combined virology and protein biochemistry to identify early SV40 virus replication and transcription complexes associated with the nuclear matrix of eukaryotic cells. He then went on to do a postdoctoral fellowship in molecular biology of the nervous system in Dr. J. Gregor Sutcliffe's lab at The Scripps Research Institute in La Jolla, CA, where he began his initial studies of neurodegenerative diseases focusing on identifying novel genes relevant to Huntington's Disease (HD). He returned to UCLA in 1989 as a member of the Mental Retardation Research Center and the Department of Psychiatry & Biobehavioral Sciences, David Geffen School of Medicine at UCLA, studying synaptic targets of neurodegenerative diseases that include Parkinson's Disease (PD), HD, and Alzheimer's Disease. He has also served as the Vice Chair of the Neuroscience Undergraduate Interdepartmental Program for the UCLA campus and Outreach Program Director for the Brain Research Institute (BRI). He is also currently an Associate Dean in the Graduate Division.
