@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%?!

Trainee Tuesday!! Join us every Tuesday to meet the rising stars in Neurotrauma research 💫
Introducing Mia Pacheco, an outstanding NNS trainee!
Mia won the Michael Goldberger Award at the 2024 National Neurotrauma Symposium for her impactful contributions to spinal cord injury research. Mia also serves on the NNS Planning Committee, and volunteers with the NNS Local Scholars Program.
Congratulations on your research and thank you for your service to the society! 🏆🧠 @mia_rayne @TAMUNeuro @TAMU_Biology

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!)

So excited to attend my first neuro and glia meeting! Can’t wait to learn all things glia and talk about my work with microglia epigenetics! #CSHLGlia
Welcome to all of our Glia in Health & Disease participants! Make sure to use #cshlglia for all your posts 🦠
A special thank you to the organizers @LiddelowSA @SchaferLabUMass
Looking forward to a great week!

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!
