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 ...

In multiple sclerosis, an “energy crisis”, which entails axonal ATP depletion, contributes to neuronal dysfunction and ensuing neurodegeneration. We have identified dysregulation of the TCA cycle and specifically depletion of its pacemaker enzyme, IDH3, as a critical checkpoint of neuronal energy homeostasis. Targeting IDH3, however, leads only to partial reversal of axonal ATP deficits, pointing to further neuroenergetic checkpoints. We now plan to identify these checkpoints and study their ...

Multiple sclerosis (MS) is an inflammatory neurological disease of the central nervous system with a subclinical phase preceding frank neuroinflammation. CD8+ T cells are abundant within MS lesions, but their potential role in disease pathology remains unclear. Using high-throughput single-cell RNA sequencing and single-cell T cell receptor analysis, we compared CD8+ T cell clones from the blood and cerebrospinal fluid (CSF) of monozygotic twin pairs in which the cotwin had either no or subclinical ...

CD8+ T cells from PBMCs of the MS twin cohort (n = 12; 6 healthy twins, 6 twins with SCNI, and 12 twins with MS; 193,771 cells) and the validation cohort (n = 17; 5 individuals with IIH and 12 individuals with MS; 89,859 cells) were isolated via FACS and processed using the 10X manufacturer's protocol to generate single-cell transcriptome and TCR libraries. The corresponding TCR sequences are included within the metadata of the uploaded objects. (Author states that fastq raw data files from humans ...
