Fine Tuning of Intracellular Ca²⁺ Content by Pharmacological Agents – A Strategy to Prevent Synapse Loss in Alzheimer Disease Hippocampal Neurons

Alzheimer disease is the dominant form of elderly dementia. Today all clinical trials that target β-amyloid have failed to indicate that β-amyloid may not be a causative agent in AD pathogenesis. Thus there is a need to search for alternative ways to treat AD patients. Neuronal store-operated calcium entry is a fine-tuning mechanism that regulates intracellular Ca²⁺ content. Recent evidence suggests that store-operated calcium channels may be targeted with pharmacological agents in order to prevent synapse loss, recover long-term potentiation and change behavior. Current mini-review discusses basic chemical structures that modulate intracellular calcium dysbalance via targeting store-operated calcium channels and their applicability as anti-AD pharmacological agents.
