| Research Abstract |
1.We identified glypican-1 as an Aβ-binding protein. Glypican-1 was enriched in the raft fraction, and deposited in senile plaques. Glypican-1 enhanced Aβ-induced cell death.
2.By using the differential display between PS1 wild and mutant cell lines, we identified a novel protein, adoplin. Adoplin was a membrane protein, and made a complex with PS1. Over expression of adoplin enhanced Aβ production.
3.By using the yeast two-hybrid system, we identified a novel Aβ-binding protein, AB-DIP, which contained CARD and nuclear targeting sequence. Overe-xpression of AB-DIP itself induced cell death and enhanced Aβ- induced cell death.
4.Neprilysin-knock-out mice were crossed with mutant PS1-transgenic mice. The mice did not show an enhancing effect of the Alzheimer phenotype.
