Shiny-based web visualisation: Astrocyte heterogeneity reveals region-specific astrogenesis in the white matter Version 1
External LinkAstrocyte heterogeneity has been well explored, but our understanding of white matter (WM) astrocytes and their distinctions from grey matter (GM) astrocytes remains limited. Here, we compared astrocytes from cortical GM and WM/corpus callosum (WM/CC) using single cell RNA-sequencing (scRNA-seq) and spatial transcriptomics of the murine forebrain. The comparison revealed similarities, but also significant differences between WM and GM astrocytes, including cytoskeletal and metabolic hallmarks specific to WM astrocytes with molecular properties also shared with human WM astrocytes. When comparing murine astrocytes from two different WM regions, cortex and cerebellum, we found that they exhibit distinct, region-specific molecular properties, with the cerebellum lacking for example a specific cluster of WM astrocytes expressing progenitor and proliferation genes. Functional experiments confirmed astrocyte proliferation in WM/CC, but not cerebellar WM, suggesting that the WM/CC may be a source of continued astrogenesis.

Neurological diseases are on the rise – and as societies age, they affect an ever-increasing number of people, not only in Europe, but worldwide.
The Munich Cluster for Systems Neurology (SyNergy) investigates how complex neurological diseases such as Alzheimer's disease, stroke, and multiple sclerosis develop. Even though these diseases differ in their clinical manifestations, overlapping mechanisms are involved in their development. For example, the immune system gets activated in dementia, ...

This project serves as a centralized repository for omics datasets published by research groups within the SyNergy Cluster. It encompasses investigations such as proteomics and transcriptomics, which are further divided into individual studies led by SyNergy members. Each study is linked to relevant publications, assays and data files (with links to external repositories).
To explore investigations and their associated studies in more detail, please visit the 'Related items' tab on the Project ...
