ミトコンドリアとリソソーム間の相互作用を可視化するための2色相関光顕微鏡と電子顕微鏡法

Executive Industry Relevance

Dual-color correlative light and electron microscopy (CLEM) enables high-resolution visualization of mitochondria-lysosome interactions, addressing a critical gap in understanding organelle dynamics relevant to disease mechanisms. This capability supports mechanistic de-risking and target validation in early discovery, particularly for programs focused on mitochondrial quality control and cellular stress responses. Integrating CLEM into discovery pipelines enhances predictive confidence for portfolio decisions involving organelle-targeted therapeutics.
