| The exciting
news: CNS neurons can sprout or
grow. |
|||||||||||||
| Challenges: |
|||||||||||||
| *Repopulate
with neurons and “good” glia |
|||||||||||||
| *Overcome
the “bad” glial environment: |
|||||||||||||
| - combat glial scars, inhibitory
extracellular matrix |
|||||||||||||
| - add blockers of myelin |
|||||||||||||
| *Help
axons regrow: |
|||||||||||||
| add neurotrophins (increase cAMP
levels to prime neurons |
|||||||||||||
| to
ignore myelin-inhibitors). |
|||||||||||||
| re-express ”youth" proteins -
GAP-43 |
|||||||||||||
| *Induce
reformation of synapses (least understood step; |
|||||||||||||
| how do normal synapses form?). |
