Over the past 20 years, I have developed two major programs in the field of neurodegenerative diseases focused on molecular mechanisms of Alzheimer’s disease (AD) and Amyotrophic Lateral Sclerosis (ALS) and on defining the molecular participants potentially amendable to therapeutic interventions using molecular biological approaches, including transgenic and gene knockout strategies. Over the past decade, we assessed BACE1 and gamma-secretase, enzymes required for the generation of beta-amyloid, as therapeutic targets for AD. We are currently developing next generation set of mouse models of AD for mechanistic studies as well as for testing therapies. My laboratory also has built mouse models of motor neuron disease for the study of ALS. More recently, my group has generated mouse models of TDP-43 in efforts to unravel the physiology and pathophysiology of this RNA binding protein implicated in ALS and Frontotemporal dementia (FTD). We recently discovered a novel function of TDP-43 in repression of splicing of non-conserved cryptic exons and disclosed that this role of TDP-43 is compromised in brains of ALS-FTD. We currently are embarking on identifying functional biomarkers and validating repression of cryptic exons as a therapeutic target for ALS-FTD.
