Cell type- and brain region-resolved mouse brain proteome.

Brain transcriptome and connectome maps are being generated, but an equivalent effort on the proteome is currently lacking. We performed high-resolution mass spectrometry-based proteomics for in-depth analysis of the mouse brain and its major brain regions and cell types. Comparisons of the 12,934 identified proteins in oligodendrocytes, astrocytes, microglia and cortical neurons with deep sequencing data of the transcriptome indicated deep coverage of the proteome.

Autonomic denervation of lymphoid organs leads to epigenetic immune atrophy in a mouse model of Krabbe disease.

Lysosomal beta-galactosylceramidase deficiency results in demyelination and inflammation in the nervous system causing the neurological Krabbe disease. In the Twitcher mouse model of this disease, we found that neurological symptoms parallel progressive and severe lymphopenia. Although lymphopoiesis is normal before disease onset, primary and secondary lymphoid organs progressively degenerate afterward.
