I started my own lab about 6 months ago at Ohio State where we’re continuing to look at ways to manipulate astrocyte biology to improve brain repair. We’re also generating new viral tools along the way, for use in research and hopefully in gene therapies for patients down the line.

Intriguing new insights on axonal TDP-43 in ALS from @labperlson.bsky.social and colleagues

www.nature.com/articles/s41...
Muscle-derived miR-126 regulates TDP-43 axonal local synthesis and NMJ integrity in ALS models - Nature Neuroscience
Ionescu, Ankol et al. show that, in ALS mouse and iPSC models, TDP-43 aggregation at NMJs stems from aberrant axonal translation, normally repressed by muscle EV-derived miR126. Loss of miR126 in ALS increases TDP-43 buildup, impairs local synthesis and triggers degeneration.
