Amyloid precursor protein processing and bioenergetics.

The processing of amyloid precursor protein (APP) to amyloid beta (Aβ) is of great interest to the Alzheimer's disease (AD) field. Decades of research define how APP is altered to form Aβ, and how Aβ generates oligomers, protofibrils, and fibrils. Numerous signaling pathways and changes in cell physiology are known to influence APP processing. Existing data additionally indicate a relationship exists between mitochondria, bioenergetics, and APP processing. Here, we review data that address whether mitochondrial function and bioenergetics modify APP processing and Aβ production.
