Description
We report XBP1 activation and regulation of pro-inflammatory signaling in astrocytes, microglia, and CNS-recruited pro-inflammatory monocytes during EAE. Overall design: Analysis of RNA expression in astrocytes, microglia, and monocytes sorted by flow cytometry. Mice transduced with astrocyte-targeting lentiviruses encoding non-targeting or Xbp1-targeting shRNAs.

Description
We report the application of single-molecule-based sequencing technology for high-throughput profiling of NSC transcriptome. Overall design: Wild type and Sox2-deleted NSC were sequenced; three independent samples from wild type, and three from Sox2-deleted brains (different individual mice).

Description
Microglia play a pivotal role in the maintenance of brain homeostasis, but lose their homeostatic function during the course of neurodegenerative disorders. We identified a specific APOE-dependent molecular signature in microglia isolated from mouse models of amyotrophic lateral sclerosis, multiple sclerosis and Alzheimer’s disease (SOD1, EAE and APP-PS1) and in microglia surrounding neuritic A?-plaques in human Alzheimer’s disease brain. This is mediated by a switch from a (M0)-homeostatic to (MGnD)-neurodegenerative phenotype following phagocytosis of apoptotic neurons via the TREM2-APOE pathway. TREM2 induces APOE signaling which is a negative regulator of the transcription program in M0-homeostatic microglia. Targeting the TREM2-APOE pathway restores the M0-homeostatic signature of microglia in APP-PS1 and SOD1 mice and prevents from neuronal loss in an acute model of neurodegeneration. In SOD1 mice, TREM2 regulates MGnD in a gender-dependent manner. APOE-mediated MGnD microglia lose their tolerogenic function. Taken together, our work identifies the TREM2-APOE pathway as a major regulator of microglial functional phenotype in neurodegenerative diseases and serves as a novel target to restore homeostatic microglia. Overall design: Illumina NextSeq500 was used to identify disease-associated vs. homeostatic molecular microglia signature in microglia in different disease models and transgenic models. Bulk microglia (1,000 cells/sample) FCRLS+ sorted microglia.
