Monitoring peripheral nerve degeneration in ALS by label-free stimulated Raman scattering imaging. | LitMetric

AI Article Synopsis

  • The study highlights the effectiveness of stimulated Raman scattering (SRS) microscopy in monitoring nerve degeneration in mouse models of amyotrophic lateral sclerosis (ALS) and autopsy samples.
  • It reveals that SRS imaging can detect significant nerve degeneration early, even before noticeable muscle and motor function decline occurs.
  • The research indicates that SRS imaging allows for long-term tracking of ALS progression and the effects of potential treatments, making it a valuable tool for studying the disease.

Article Abstract

The study of amyotrophic lateral sclerosis (ALS) and potential interventions would be facilitated if motor axon degeneration could be more readily visualized. Here we demonstrate that stimulated Raman scattering (SRS) microscopy could be used to sensitively monitor peripheral nerve degeneration in ALS mouse models and ALS autopsy materials. Three-dimensional imaging of pre-symptomatic SOD1 mouse models and data processing by a correlation-based algorithm revealed that significant degeneration of peripheral nerves could be detected coincidentally with the earliest detectable signs of muscle denervation and preceded physiologically measurable motor function decline. We also found that peripheral degeneration was an early event in FUS as well as C9ORF72 repeat expansion models of ALS, and that serial imaging allowed long-term observation of disease progression and drug effects in living animals. Our study demonstrates that SRS imaging is a sensitive and quantitative means of measuring disease progression, greatly facilitating future studies of disease mechanisms and candidate therapeutics.
