Dr. Shelanski's laboratory is investigating the mechanism of memory disruption and synaptic dysfunction in Alzheimer's Disease. They use a combination of cell culture and transgenic animal approaches in an attempt to understand why the overexpression 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. These results are extended with analyses of neurons taken from post-mortem Alzheimer's Disease brains.

In the past two years their 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. They have used both drugs and protein transduction techniques to show that A-beta induced changes, both in culture and in the animal, can be reversed by restoring these pathways to their normal "balance". Other projects involve the induction of neurogenesis in neural stem cells by A-beta raising the possibility of an endogenous repair mechanism in AD, and the analysis of the action of the ginkgolides on neuronal function.

The laboratory approaches these questions with a wide range of tools including biochemistry, cell biology, physiology and microscopy.

We are using a combination of cell biological and molecular biological approaches, including anti-sense technology, to study the function of two proteins: the intermediate filament peripherin and the high molecular weight form of the microtubule associated protein tau. These proteins are characteristic of the cytoskeleton of the peripheral neuron. We are interested in why there are differences between the central and peripheral cytoskeleton and whether these differences are related to the greater regenerative potential of peripheral neurons. To aid in this effort we have set up a model "axon" using baculovirus expression and insect SF9 cells to assess interactions between specific cytoskeletal components. A related series of studies is investigating the mechanism by which astrocytes and neurons initiate the formation of long asymmetric processes. Our approach has shown that process formation in the astrocyte is inhibited by the cortical actin network and favored by the assembly of microtubules. This equilibrium is controlled by the myosin light chain kinase acting on the myosin light chain and on destrin, an actin-severing protein. These studies utilize a variety of cell biology approaches including biochemistry, EM, optical imaging and antisense oligonucleotides. Other research in the laboratory is on the role of cytokines, specifically IL-1, on the development of cytoskeletal changes in Alzheimer's disease.
