Molecular and Cellular Signals Controlling Neurodegeneration, Neuronal Survival and Cell Death
The Dawson lab studies molecular mechanisms of neurodegeneration of Parkinson’s disease, nitric oxide signaling and neuronal cell death and neuroprotective and neurorestorative strategies in neurodegenerative diseases, stroke and trauma.
Parkinson’s disease is a common neurodegenerative disorder and the Dawson lab is studying the genetic basis of PD by investigating the mechanisms by which mutations in familial-linked genes cause PD, with hopes of identifying potential therapeutic targets for developing PD treatments. Current projects include the study of alpha-synuclein, LRRK2, parkin and PINK1.
Nitric oxide is a major player in neuronal cell death and the Dawson team has discovered parthanatos, a caspase-independent programmed cell death pathway involving apoptosis inducing factor (AIF) downstream of NO and its major target poly (ADP-ribose) polymerase (PARP). The team now is further characterizing that pathway to identify targets of AIF and the roles of other cell death effectors with the hope of identifying new signaling pathways that might be amenable to therapeutic intervention. In addition they are investigating the role of poly (ADP-ribose) as signaling molecule.
