Recent studies provide compelling evidence that altered Ca2+ homeostasis may underlie disease pathomechanism and be an inherent feature of all vulnerable neurons. The downstream effects of altered Ca2+ handling in the distinct subcellular organelles for proper cellular function are beginning to be elucidated. Here, we summarize the evidence that vulnerable neurons may be exposed to homeostatic Ca2+ stress which may determine their selective vulnerability, and suggest how abnormal Ca2+ handling in the distinct intracellular compartments may compromise neuronal health in the context of aging, environmental, and genetic stress. Gaining a better understanding of the varied effects of Ca2+ dyshomeostasis may allow novel combinatorial therapeutic strategies to slow PD progression. %K Parkinson¡¯s disease %K dopamine %K calcium %K mitochondria %K endoplasmic reticulum %K lysosomes %K Golgi %U http://www.frontiersin.org/Journal/10.3389/fnmol.2014.00053/abstract
