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).

Direct neuronal reprogramming is a promising approach to regenerate neurons from local glial cells. However, mechanisms of epigenome remodeling and co-factors facilitating this process are unclear. In this study, we combined single-cell multiomics with genome-wide profiling of three-dimensional nuclear architecture and DNA methylation in mouse astrocyte-to-neuron reprogramming mediated by Neurogenin2 (Ngn2) and its phosphorylation-resistant form (PmutNgn2), respectively. We show that Ngn2 drives ...

Astrocyte heterogeneity has been well explored, but our understanding of white matter (WM) astrocytes and their distinctions from gray matter (GM) astrocytes remains limited. Here, we compared astrocytes from cortical GM and WM/corpus callosum (WM/CC) using single-cell RNA sequencing 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 play key roles in brain function, but how these are orchestrated by transcription factors (TFs) in the adult brain and aligned with astrocyte heterogeneity is largely unknown. Here we examined the localization and function of the novel astrocyte TF Trps1 (Transcriptional Repressor GATA Binding 1) and the well‐known astrocyte TF Sox9 by Cas9‐mediated deletion using Mokola‐pseudotyped lentiviral delivery into the adult cerebral cortex. Trps1 and Sox9 levels showed heterogeneity among ...

PTEN-induced kinase 1 (PINK1) is a short-lived protein required for the removal of damaged mitochondria through Parkin translocation and mitophagy. Because the short half-life of PINK1 limits its ability to be trafficked into neurites, local translation is required for this mitophagy pathway to be active far from the soma. The Pink1 transcript is associated and cotransported with neuronal mitochondria. In concert with translation, the mitochondrial outer membrane proteins synaptojanin 2 binding ...

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 ...

Single cell multiome (scRNA-seeq + scATAC-seq), bulk ATAC-seq, bulk RNA-seq, ChIP-seq, Cut&Run and Methyl-HiC was performed on primary mouse astrocytes (2 days post induction) transduced with doxycycline-inducible lentiviral constructs expressing either GFP, Ngn2 and PmutNgn2 respectively. Since the constructs also expressed GFP, the astrocytes were FACS sorted based on GFP expression. To profile the effect of Yy1 on direct neuronal reprogramming. scRNA-seq and bulk ATAC-seq was performed on ...

Astrocyte 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 ...

Astrocyte heterogeneity has been extensively studied, but our understanding of white matter (WM) astrocytes and their distinctions from grey matter (GM) astrocytes remains limited. We directly compared astrocytes from cortical GM, WM, and the subependymal zone using scRNA-seq and spatial transcriptomics of murine forebrain sections. The comparison revealed significant differences between WM and GM astrocytes, including cytoskeletal and metabolic hallmarks specific to WM astrocytes. Furthermore, ...

Astrocytes play key roles in brain function but it is still poorly understood how these are orchestrated by pan-astrocyte transcriptions factors (TFs). Here we examined the function of the well-known pan-astrocyte TF Sox9 and the novel astrocyte TF Trps1 (Transcriptional Repressor GATA Binding 1) by Cas9-mediated in vivo deletion using Mokola-pseudotyped lentiviral delivery into the adult cerebral cortex. The consequences of deleting either Sox9 or Trps1 alone or simultaneously were explored at ...
