Expression profiling: Bulk RNA-seq (rat)

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) involves the infiltration of autoreactive T cells into the CNS, yet we lack a comprehensive understanding of the signaling pathways that regulate this process. Here, we conducted a genome-wide in vivo CRISPR screen in a rat MS model and identified 5 essential brakes and 18 essential facilitators of T cell migration to the CNS. While the transcription factor ETS1 limits entry to the CNS by controlling T cell responsiveness, three functional modules, centered around the ...

To study the effect of the Grk2 or Ets1 KOs in rat and human CD4+ T cells, in vivo or in vitro respectively, we generated KO CD4+ T cell lines by CRISPR-RNP nucleofection (with an gRNA targeting the gene locus) or control (with a non-targeting gRNA) 3' bulk RNAseq was conducted on CD4+ T-MBP rat cells isolated form spleen or spinal cord parenchyma three days after co-transfer of control and KO cells into the animal. Cells were FACS sorted based on their fluorescent protein reporters, BFP for ...
