    Abstract: Accumulated A beta is one of the hallmarks of Alzheimer's disease. Although accumulated results from in vivo and in vitro studies have shown that accumulated A beta causes learning and memory deficit, cell death, and lifespan reduction, the underlying mechanism remains elusive. In neurons, calcium dynamics is regulated by voltage-gated calcium channel (VGCC) and endoplasmic reticulum and is important for neuron survival and formation of learning and memory. The current study employs in vivo genetics to reveal the role of calcium regulation systems in A beta-induced behavioral damage. Our data shows that although increased VGCC improves learning and memory in A beta 42 flies, reduction of VGCC and Inositol trisphosphate receptors extends A beta 42 flies' lifespan and improves cell viability. The complex role of calcium regulation systems in A beta-induced damage suggests that the imbalance of calcium dynamic is one of the main factors to trigger learning and memory deficit and cell death in the disease.
