Calcium Signaling Dysregulation In Alzheimer'S Disease represents a key pathological mechanism in neurodegenerative diseases. This page explores the molecular and cellular processes involved, their contribution to disease progression, and therapeutic implications.
Neurons rely on tightly regulated calcium signaling to maintain:
In AD, multiple factors disrupt calcium homeostasis, including amyloid-beta (Aβ) oligomers, tau pathology, mitochondrial dysfunction, and dysregulated ion channels.
Aβ peptides can form calcium-permeable ion channels in neuronal membranes:
