Research Interests

• My research focus is now targeted towards using recombinant Adeno-associated virus (rAAV) to study of neurological disorders. We have examined the use of rAAV to over express proteases including neprilysin (NEP), insulin degrading enzyme (IDE; also known as insulysin) and endothelin converting enzyme (ECE) to remove beta-amyloid which is deposited in Alzhiemer disease. To facilitate the diffusion of the protease enzymes to the amyloid plaques, we have engineered the proteins with a signal peptide triggering secretion. We have successfully observed a reduction in amyloid plaques with both NEP and ECE in APP+PS1 transgenic Alzheimer mice models. We are also using rAAV to study an inflammatory molecule known as Fractalkine. Fractalkine reduces the pro-inflammatory response that is observed in many neurological diseases. We are examining whether this reduction in inflammation would be beneficial in Alzheimer and Parkinson's diseases.
