Calcium plays a pivotal role in mediating many important biological functions. The intracellular calcium concentration is tightly regulated by a variety of systems and mechanisms. Calcium is sequestered by various organelles such as mitochondria and/or endoplasmic reticulum and extruded across the plasma membrane by energy-dependent transport systems. Different Ca 2+ -binding proteins are...
The a β peptide is a neurotoxic peptide that accumulates in the brains of Alzheimer patients, but is also present in body fluids at subnanomolar levels. The potential effects of these low levels of a β are unclear. We now show that one such action is to increase tyrosine phosphorylation in PC12 cells and olfactory neuroblasts. Application of a β 25–35 or a β 1–40 induces a dose-dependent...
