- Extremely happy to share our manuscript jointly authored by me and the amazing Lyndsay Osso! An awesome collaboration between the @ethanhugheslab.bsky.social , Dan Denman and Autobahn Therapeutics. www.nature.com/articles/s41... 🧵
- We used longitudinal in vivo 2P imaging and Neuropixels recordings in the cuprizone model to gain insights into important aspects of remyelination: 1. Endogenous remyelination is insufficient when demyelination is too severe and occurs too quickly
- 2. The drive for remyelination is recent loss of oligodendrocytes, not a restoration of the original oligodendrocyte population. So, there may be un unknown factor released around the timing of oligodendrocyte loss to promote remyelination
