Alterations in store-operated calcium entry in neurodegenerative pathologies: history, facts, perspectives

Neurodegenerative disorders, along with cardiovascular and oncological pathologies, are one of the most actual issues facing modern medicine. Therefore, the study of the molecular mechanisms of their pathogenesis and the search for new drug targets is highly demanded. Neuronal calcium signalling has attracted close attention, as altered calcium homeostasis has been demonstrated in the pathogenesis of various neurodegenerative diseases. In this review, we focus on one of the most ubiquitous and important pathways for calcium uptake: store-operated calcium entry. Here we describe studies demonstrating disturbances in store-operated calcium entry in various neurodegenerative pathologies, including Alzheimer’s, Parkinson’s and Huntington’s diseases. Also, we analyse the molecular determinants underlying these disturbances and propose ways for pharmacological correction of altered calcium signaling. The information summarized in the review will allow us to consider store-operated calcium channels as promising targets for the drug development in order to treat neurodegenerative pathologies and outline further promising directions for the investigation.
