Presenilin-1 mutations and Alzheimer's disease.
Mutations in the PSEN1 gene, encoding presenilin-1 (PS1), are themost common cause of familial Alzheimer’s disease (FAD). PS1 functions as the catalytic subunit of γ-secretase, an intramembranous protease that cleaves a variety of type 1 transmembrane proteins, notably including the amyloid precursor protein (APP) and Notch. Following prior cleavage by β-secretase, processing of APP by γ-secret...

متن کاملOverexpression in neurons of human presenilin-1 or a presenilin-1 familial Alzheimer disease mutant does not enhance apoptosis.
Programmed cell death, or apoptosis, has been implicated in Alzheimer's disease (AD). DNA damage was assessed in primary cortical neurons infected with herpes simplex virus (HSV) vectors expressing the familial Alzheimer's disease (FAD) gene presenilin-1 (PS-1) or an FAD mutant of this gene, A246E. After infection, immunoreactivity for PS-1 was shown to be enhanced in infected cells. The infect...
متن کاملCSF Presenilin-1 complexes are increased in Alzheimer’s disease
BACKGROUND Presenilin-1 (PS1) is the active component of the amyloid precursor protein cleaving γ-secretase complex. PS1 protein is a transmembrane protein containing multiple hydrophobic regions which presence in cerebrospinal fluid (CSF) has not been measured to date. This study assesses whether PS1 and other components of the γ-secretase complex are present in CSF. RESULTS Here, we show th...
