高解像度呼吸法による坐骨神経のミトコンドリア機能の評価

Executive Industry Relevance

High-resolution respirometry in permeabilized sciatic nerve enables direct, quantitative assessment of mitochondrial function in small, disease-relevant peripheral nerve samples. This approach addresses a critical gap in early discovery and target validation for neuropathy-related drug development by providing simultaneous measurement of oxygen consumption and reactive oxygen species (ROS) production. The method supports predictive confidence in mitochondrial dysfunction as a mechanistic driver of neuropathies, informing portfolio triage and therapeutic hypothesis testing.
