Professor Shelanski's laboratory is investigating the mechanism of memory disruption and synaptic dysfunction in Alzheimer's Disease. The lab uses a combination of cell culture and transgenic animal approaches in an attempt to understand why the over-expression of the amyloid precursor protein (APP) or direct application of its active peptide, A-beta, inhibits intracellular signaling in neuronal cells and leads to alterations of electrical activity, dendritic spine morphology and behavior. In the past two years, Shelanski's attention has been on the PKA-CREB signaling pathway and on the role of ubiquitin c-terminal hydrolase-L1 (Uch-L1) in regulating these events.
