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 ...

Neuronal loss in acute or chronic brain disease could be treated by neuronal replacement strategies, such as transplantation of young neurons, if they integrate properly into the existing networks. Here we explore the cell-based and molecular mechanisms causing hyperinnervation and overshoot loss of input connectivity as well as the newly discovered hurdle in output connectivity, the lack of myelination. Candidate as well as unbiased approaches are pursued to identify the critical checkpoints and ...

Mitochondria account for essential cellular pathways, from ATP production to nucleotide metabolism, and their deficits lead to neurological disorders and contribute to the onset of age-related diseases. Direct neuronal reprogramming aims at replacing neurons lost in such conditions, but very little is known about the impact of mitochondrial dysfunction on the direct reprogramming of human cells. Here, we explore the effects of mitochondrial dysfunction on the neuronal reprogramming of induced ...
