@willaise is an awesome scientist (and person and father!). Profound findings and lots to follow up on! Congrats!
My fav finding: transplanting healthy immune cells reduces pathology in other diseased host cells. How does fixing ~10% of the brain help the other 90%?!

Biggest medical discoveries of the week (🧵)
1/10
Spinal cord injury triggers activation of T cells, inflammation, and death of neurons
Editing the T cell receptor, using mRNA, suppressed this, and helped recovery from the injury (in mice!)

interested in knowing what glia cells will be discussed at #CSHLGlia @cshlmeetings next week?
here is a breakdown \\
take homes:
1. astro, oligo, micro make up most of the community
2. we pushed hard to have extra peripheral glia in the oral presentations
3. 5 SLEEPS!
