Executive Industry Relevance

Disrupted axonal transport is a convergent mechanism in neurodegenerative disease pathogenesis, impacting target validation and mechanistic de-risking in early discovery. Live-cell imaging of primary hippocampal neurons enables quantitative assessment of how pathological proteins, such as mutant tau, alter cargo dynamics, supporting predictive confidence in disease-relevant systems. This reproducible workflow informs portfolio triage and prioritization of neurodegeneration targets by clarifying mechanistic liabilities.
