Microglia are resident myeloid cells of the central nervous system integral for neuroprotective and neurodegenerative processes. Here the authors describe a unique TGF-β dependent molecular and functional microglia signature that distinguishes these cells from other immune and glial cells in the periphery and brain.
In this Resource, the authors generate a genome-wide methylation profile of DNA from the normal-appearing white matter of control and multiple sclerosis–affected brains and find subtle, but widely distributed, differences. In particular, they report that hypermethylated genes that regulate oligodendrocyte survival are also transcriptionally downregulated.
In this Resource study, the authors used Direct RNA Sequencing (DRS) to quantitatively examine the transcriptional profile of microglia, focusing specifically on the proteins important for binding endogenous ligands and potential pathogens—a collection they term the 'sensome'. They also compare this profile to that of peripheral macrophages.
Using whole-transcriptome RNA sequencing at single-nucleotide resolution, this Resource article describes the mRNAs, RNA editing, splice variants and exon-intron boundaries of expressed genes in the cerebral cortex of embryonic and adult mice.
In this Resource study, the authors used high-resolution mass spectrometry to elucidate the precise proteomic complement of the inner ear hair bundle. Many of the proteins that are enriched in the hair bundles are encoded by known deafness-associated genes.
