Hypothesis
Prohibitin-2 Mitochondrial Cross-Seeding Hub Disruption
Prohibitin-2 serves as a convergent mitochondrial platform where tau, α-synuclein, and TDP-43 interact and undergo conformational templating.

🧪 Overview
Prohibitin-2 serves as a convergent mitochondrial platform where tau, α-synuclein, and TDP-43 interact and undergo conformational templating. Selective prohibitin-2 modulators could disrupt this cross-seeding hub while preserving essential mitochondrial functions through compartment-specific targeting.

⚖️ Evidence Matrix3 supports3 contradicts
Supports
TDP-43 pathology involves mitochondrial dysfunction and prohibitin complex disruption
Contradicts
Prohibitin-2 is essential for mitochondrial function, making selective modulation challenging
Contradicts
TDP-43 mitochondrial localization may be secondary to other pathological processes
Contradicts
Prohibitin complex disruption often reflects rather than causes neurodegeneration
