C03 - Cellular and molecular checkpoints of circuit refinement following traumatic injuries of the CNS
Actions
Order Studies
There is to date no therapy that prevents the devastating consequences of traumatic brain and spinal cord injuries. Previous work has shown that neuronal connections can spontaneously remodel after CNS injuries, a process that contributes to functional recovery. Here, we propose that the balance between adaptive and maladaptive neuronal remodeling depends on circuit refinement and is guided by the interplay between neuronal activity and microglia-driven synapse removal. We aim to identify the checkpoints for circuit refinement and reveal whether such checkpoints are maintained between different injury types and locations.

https://rdp.sfb274.de/ (Research Data Platform) https://gepris.dfg.de/gepris/projekt/408885537 (DFG Gepris entry) The central nervous system (CNS) is a terminally differentiated tissue, where any insult carries a heightened risk - yet the tissue response to these insults is variable and can range from irreversible destruction to almost complete recovery. The rules that instruct these divergent outcomes are still unknown. The aim of this CRC is therefore to understand the biology of the multicellular ...

Concussions are a current health concern and account for the vast majority of head trauma. While symptoms after a single impact are usually transient, repetitive concussions, as often occur in sports, are responsible for persistent acute and chronic deficits. Here, we used a model of bilateral midline-centered concussions in mice to show that repetitive concussions selectively induce impairments in learning ability compared to single-impact injuries. Since microglial cells and their activation ...
