Expression profiling: Spatial Transcriptomics (mouse)

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 ...

Traumatic brain injuries (TBIs) cause primary tissue damage and activate glial cells to build glial border, thereby delineating the injured brain parenchyma from the healthy surrounding tissue. However, this necessary primary reaction of glial cells often persists. This long-lasting glial activation results in prolonged and exacerbated neuroinflammation that prevents tissue restoration. We propose that a cross-regulatory network between innate immunity pathways and EV cargo defines an important ...

Traumatic brain injury leads to a highly orchestrated immune- and glial cell response partially responsible for long-lasting disability and the development of secondary neurodegenerative diseases. A holistic understanding of the mechanisms controlling the responses of specific cell types and their crosstalk is required to develop an efficient strategy for better regeneration. Here, we combine spatial and single-cell transcriptomics to chart the transcriptomic signature of the injured male murine ...
