About

The brain immune atlas provides a resource and visualization tool for assessing the single-cell RNA sequencing datasets generated by the Movahedi lab, which capture human and mouse brain immune cells in health and disease. You can visualize the expression of individual genes and/or download differentially expressed gene lists that define immune cell clusters. Gene-cell count and cell annotation matrices can be downloaded as well. Currently, our website hosts datasets originating from three publications: 1. Van Hove et al. Nature Neuroscience 2019; 2. Pombo-Antunes, Scheyltjens et al. Nature Neuroscience 2021; 3. Shemer et al. Immunity 2020.

 
 

1. A single-cell atlas of mouse brain macrophages

2. Human and mouse Glioblastoma immune atlas

Using the 10x genomics chromium platform, we analyzed more than 61.000 CD45+ immune cells that were obtained from whole brains or isolated border regions, including the dura mater, subdural meninges and choroid plexus. Datasets were obtained from WT homeostatic mice, conditional Irf8 knockout animals and aged APP/PS1 transgenics.

Here, we mapped the glioblastoma immune landscape in newly diagnosed and recurrent patients and in mouse tumors via scRNA-seq and CITE-seq analysis. This revealed a large and diverse myeloid compartment, with dendritic cell and macrophage populations that were conserved across species and were dynamic across disease stages.

 

3. Brain immune cells following peripheral endotoxin challenge

To assess for transcriptional changes in brain immune cells following acute peripheral endotoxin challenge, we sorted CD45+ immune cells from the brains of C57BL/6 mice 12 h post-PBS or LPS injection. To enrich for non-microglial immune cells that are mostly present in the brain’s border regions, we separately sorted microglia and CD45+ non-microglial cells, mixed them at a 1:9 ratio and performed 10x scRNA-seq analysis.
