Summary
With type-2 diabetes representing a major risk factor for neurodegenerative diseases such as Alzheimer's disease, it is important to understand the underlying mechanisms. This project will provide significant insight into how T2D impacts the brain with a focus on how deficiencies in brain inuslin signaling drives neurodegeneration. We will also evaluate novel inuslin like molecules at improving brain insulin siganling and preventing or slowing down the neurodegenerative process.

Summary
The Presenilin and APP proteins are centrally important in inherited, early onset Alzheimer's disease. We have discovered that a shortened form of Presenilin protein, "PS2V", appears to increase specifically the rate at which the APP protein is cleaved to produce the "Amyloid beta" protein fragment that is found in Alzheimer's disease brains. This occurs when brain cells are under oxidative stress. Understanding this process will facilitate development of appropriate therapeutic strategies for t ....The Presenilin and APP proteins are centrally important in inherited, early onset Alzheimer's disease.

Subcellular recruitment of a RhoA ubiquitination complex by Rnd proteins. This study addresses a novel molecular mechanism through which members of the Rnd family of GTP-binding proteins regulate the morphology and migration of immature nerve cells of the developing nervous system. This study has broad implications for the understanding of cell migration during embryo development, as well as in health and disease.
