アルツハイマー病(AD)の神経モデルにおけるミトコンドリア関連小胞体膜(MAM)安定化の定量的解析

Executive Industry Relevance

Quantitative analysis of MAM stabilization in live neural models addresses a critical gap in early Alzheimer's disease (AD) research by enabling direct measurement of subcellular interactions implicated in disease initiation. This capability enhances predictive confidence in target validation and supports mechanistic de-risking at the discovery stage. The method's quantitative outputs inform portfolio triage and prioritization for neurodegenerative disease programs.
