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 ...

The cerebral cortex contains a special, perineuronally localized population of oligodendrocyte lineage cells with possible functions in connectivity and myelination. We hypothesize that this cell population serves as a reservoir of remyelinating cells after myelin damage. We will apply spatial transcriptome analysis with subcellular resolution in experimental models of demyelination and human tissue from patients with multiple sclerosis to define physiological and pathological states of perineuronal ...

As tissue-resident macrophages of the central nervous system parenchyma, microglia perform diverse essential functions during homeostasis and perturbations1. They primarily interact with neurons by means of synaptic engulfment and through the rapid elimination of apoptotic cells and non-functional synapses2. Here, by combining unbiased lipidomics and high-resolution spatial lipid imaging, deep single-cell transcriptome analysis and novel cell-type-specific mutants, we identified a previously ...
