Hypothesis
Mitochondrial ROS from complex I and cardiolipin instability forms a local organelle damage loop
Electron leak at complex I and destabilized inner-membrane architecture generate superoxide and lipid oxidation that damage ETC components, dissipate membrane potential, and further increase electron leak.

🧪 Overview
Electron leak at complex I and destabilized inner-membrane architecture generate superoxide and lipid oxidation that damage ETC components, dissipate membrane potential, and further increase electron leak. This creates a direct mitochondrial self-amplifying loop, but it competes with alternative ROS origins such as iron chemistry, dopamine oxidation, and inflammatory oxidases. It is mechanistically plausible yet less complete as a whole-tissue explanation.

⚖️ Evidence Matrix3 supports2 contradicts
Supports
CoQ10 is reduced in PD substantia nigra mitochondria, consistent with impaired mitochondrial redox buffering.
Supports
MitoQ protects against rotenone-induced complex I dysfunction and oxidative damage.
Contradicts
Large CoQ10-class clinical efforts did not clearly meet primary efficacy expectations in PD.
Contradicts
Lowering mitochondrial ROS alone may not stop downstream lipid peroxidation or death commitment if non-mitochondrial ROS sources dominate.

🔮 Falsifiable Predictions (2)
pendingconf 45%
IF human dopaminergic neurons carrying pathogenic NDUFV1 or NDUFV2 variants are treated with mitochondria-targeted coenzyme Q analogue (MitoQ) to scavenge complex I-derived superoxide, THEN mitochondrial membrane potential (ΔΨm) will increase by ≥15% and cellular ATP will increase by ≥20% relative t
Predicted outcome: Restored ΔΨm and increased ATP production in patient neurons with complex I variants
Falsification: No significant change in ΔΨm or ATP levels (<5%) following MitoQ treatment, indicating complex I-derived ROS is not the limiting factor in mitochondrial dysfunction for these variants
pendingconf 40%
IF cardiolipin peroxidation is specifically blocked in Ndufv2 knockdown mice via transgenic expression of cardiolipin-specific peroxidase (GPX4-cardiolipin fusion), THEN dopaminergic neuronal loss will be reduced by ≥40% and motor deficit progression will slow by ≥30% compared to Ndufv2 knockdown mi
Predicted outcome: Reduced neurodegeneration and slower functional decline when cardiolipin peroxidation is prevented despite complex I deficiency
Falsification: No significant difference in neuronal survival or motor behavior (<10% change) between GPX4-cardiolipin transgenic and control Ndufv2 knockdown mice, indicating the damage loop is non-essential or ope
