Cover Story: Alzheimer's disease (AD) disrupts intracellular Ca2+ signaling, accelerating neurodegeneration. Inositol 1,4,5-trisphosphate receptors (IP3Rs) on the ER membrane mediate Ca2+ release; familial AD mutations in presenilin-1/2 exaggerate IP3R-driven Ca2+ release and impair ER uptake. Using a stochastic 3-state Markov IP3R model integrated into a whole-cell Ca2+ framework, we show that open probability, puff amplitude, duration, and oscillation frequency are significantly elevated in AD versus wild-type (WT) cells, consistent with experimental data. IP3R emerges as a key therapeutic target for AD. View this paper
