2006 Grant - Duff

p25/cdk5 in Alzheimer's Disease Pathogenesis

Karen Duff, Ph.D.

2006 Zenith Fellows Award

One of the hallmarks of Alzheimer's disease pathology is the assembly of the beta-amyloid protein fragment into structures that appear to have a toxic effect on neurons. Although much is known about the identity and function of proteins immediately involved in the production of beta-amyloid, there are most likely other molecular events that precede, regulate and influence beta-amyloid-related proteins and their activities.

Karen Duff, Ph.D., and colleagues are investigating the work of a protein called p25, which activates a specialized protein called cdk5. Their studies have shown elevations of the p25/cdk5 pair are associated with an increase in beta-amyloid production. In this current work, the investigators will use cell cultures to exam the mechanisms by which p25/cdk5 contributes to this phenomenon.

They will focus on how p25/cdk5 may influence BACE, one of the proteins directly involved in beta-amyloid production. They hope to characterize how p25/cdk5 exerts its influence, what physiological consequences result from its influence, and how it may exacerbate Alzheimer's disease pathology. A better understanding of these earlier players and events may shed light on factors contributing to Alzheimer pathology and suggest new targets for drug development.
