Research Interests

The ATP-binding cassette transporter-2 and Alzheimer's disease.

A major focus of Dr. Davis' lab has been investigating the mechanisms regulating the proteolytic processing of the amyloid precursor protein (APP) into neurotoxic Abeta peptide fragments, which have been implicated in the etiology of Alzheimer's disease (AD). Current research has revealed that the ATP-binding cassette transporter-2 (ABCA2) is a key regulator of amyloid precursor protein metabolism. Recent epidemiological studies have identified a strong genetic link between ABCA2 and Alzheimer's disease. Future studies will investigate the role of ABCA2 in AD through in vivo ABCA2 knockout and transgenic mouse approaches.
