Hypothesis

ER-mitochondria contact-site dysfunction in neurodegeneration

Altered mitochondria-associated membranes may disrupt calcium transfer, lipid synthesis, ROS handling, and apoptotic thresholds in neurodegeneration.

🧪 Overview

Altered mitochondria-associated membranes may disrupt calcium transfer, lipid synthesis, ROS handling, and apoptotic thresholds in neurodegeneration. The hypothesis needs disease-, cell-type-, and stage-specific directionality because either excessive coupling, insufficient coupling, or altered contact composition could be pathogenic.

🧬 Mechanism

No curated mechanism pathway recorded for this hypothesis.

⚖️ Evidence

⚖️ Evidence Matrix3 supports2 contradicts
Supports
MFN2 mutations cause Charcot-Marie-Tooth disease type 2A, linking ER-mitochondria and mitochondrial dynamics machinery to neurodegeneration.
Supports
MAM dysfunction has been reported in AD models.
Supports
Presenilins regulate ER-mitochondria coupling, connecting familial AD biology to MAM function.
Contradicts
MAM dysfunction is directionally ambiguous; too much, too little, or altered composition may each occur depending on model and disease stage.
Contradicts
Proximity assays can show organelle closeness without proving functional calcium transfer, lipid flux, respiration, survival benefit, or therapeutic direction.
