Expression profiling: scRNA-seq (human)

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 ...

Compartmentalized inflammation is a key driver of multiple sclerosis (MS) progression, but the mechanisms sustaining its persistence remain unclear. A hallmark of this persistent and slowly evolving inflammatory process is chronic active MS lesions. We generated a high-resolution, single-cell molecular and spatial atlas of such lesions by combining single-nucleus RNA sequencing (snRNA-seq) with multiplexed error-robust fluorescence in situ hybridization (MERFISH). Within lesion rims, we identified ...

Frozen autopsy brain tissue from fourteen multiple-sclerosis donors and three neurologically healthy controls was sectioned at –20 °C into 80–100 µm slices, and an 8 mm punch (~25 mg) of white matter or matched control tissue was collected from each region of interest . Nuclei were liberated with the 10x Genomics Chromium Nuclei Isolation Kit, using an extended lysis–debris-removal protocol tailored to lipid-rich white matter; the final suspension was stained with propidium iodide and counted ...
