Turning back the clock for Schwann cells

Myelin-making Schwann cells have an ability every aging Hollywood star would envy: they can become young again. According to a study appearing in the May 19 issue of the Journal of Cell Biology , David B. Parkinson (University College London, London, UK) and collogues have pinned down a protein t...
