Presenilin mutations and calcium signaling defects in the nervous and immune systems.

Abstract excerpt

Presenilin-1 (PS1) is thought to regulate cell differentiation and survival by modulating the Notch signaling pathway. Mutations in PS1 have been shown to cause early-onset inherited forms of Alzheimer's disease (AD) by a gain-of-function mechanism that alters proteolytic processing of the amyloid precursor protein (APP) resulting in increased production of neurotoxic forms of amyloid beta-peptide. The present...
