Research title
Regulation of amyloid-β molecular composition by altering spiking patterns in vivo.

Research project

Accumulated genetic evidence suggests that attenuation in the ratio between cerebral amyloid-β isoforms, Aβ40 and Aβ42, is central to familial Alzheimer’s disease pathogenesis. The composition of Aβ, namely Aβ40/42 ratio, has been shown to regulate the aggregation kinetics of the peptide in vitro and correlate with severity of the symptoms in AD patients. In order to understand the experience-dependent mechanism leading to AD I explore the relationship between spiking pattern and Aβ40/42 dynamics in vivo and molecular mechanisms underlying change in the Aβ composition by neuronal pattern of activity.
