Calcium Signal Dependent Cell Death by Presenilin-2 Mutation in PC12 Cells and in Cortical Neuron from Presenilin-2 Mutation Transgenic Mice

Familial form of Alzheimer's disease (FAD) is caused by mutations in presenilin-1 (PS-1) and presenilin-2 (PS-2). PS1 and PS2 mutation are known to similar effects on the production of amyloid ${\beta}$ peptide (A${\beta}$) and cause of neuronal cell death in the brain of patient of AD. The importance of the alternation of cellular calcium homeostasis in the neuronal cell death by PS1 mutation in a variety of experimental systems has been demonstrated.(omitted)
