Overview
- A University of Notre Dame team compared two common mouse models of demyelination, cuprizone (CPZ) and lysophosphatidylcholine (LPC), in a Nature Communications paper.
- The models follow different patterns of damage, with CPZ causing gradual, widespread myelin loss and LPC creating a fast, focused lesion with a stronger immune response.
- Based on these patterns, the authors recommend CPZ to study myelin-making cells and repair, and LPC to study how immune cells react to myelin loss.
- The researchers built single-cell RNA sequencing maps of lesions from each model and matched them to human multiple sclerosis tissue to confirm relevance to patient disease.
- They found model-specific gene-expression changes whose effects on repair are not yet known, and say the work, funded by the National Multiple Sclerosis Society, could sharpen preclinical choices and speed efforts to restore lost myelin.
