(Submitter supplied) 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. more...

(Submitter supplied) Triggering receptor expressed on myeloid cells 2 (TREM2) sustains microglia response to brain injury stimuli including apoptotic cells, myelin damage, and amyloid β (Aβ). Alzheimer’s Disease (AD) risk is associated with the TREM2R47H variant, which impairs ligand binding and consequently microglia responses to Aβ pathology. Here we tested whether TREM2 engagement by an agonistic mAb, hT2AB, designated as a surrogate ligand facilitates microglia responses in 5XFAD transgenic mice that accumulate Aβ and express either the common TREM2 variant (TREM2CV) or TREM2R47H. more...

(Submitter supplied) CD33-/- and/or TREM2-/- mice were crossed with the 5xFAD mouse model of Alzheimer’s disease to generate single and double CD33/TREM2 knock-out mice on 5xFAD background. Transcriptome and gene expression analyses were performed to analyze the impact of CD33 and/or TREM2 knock-out on the transcriptome of microglia in the context of amyloid pathology. The results revealed that CD33 and/or TREM2 knock-out reprogrammed microglial gene expression signatures in 5xFAD mice in an age-dependent manner. more...

(Submitter supplied) Microglia are central players in Alzheimer’s Disease (AD) pathology, but analyzing microglia states in human brain samples is challenging due to genetic diversity, postmortem delay and admixture of pathologies. To circumvent these issues, here we generated 138,577 single cell expression profiles of human stem cell-derived microglia xenotransplanted in the brain of the AppNL-G-F model of amyloid pathology and wild type controls. more...

(Submitter supplied) While genetics highlight the role of microglia in Alzheimer’s disease (AD), one third of putative AD-risk genes lack adequate mouse orthologs. Here, we successfully engraft human microglia derived from embryonic stem cells in the mouse brain. The cells recapitulate transcriptionally human primary microglia ex vivo and show expression of human specific AD-risk genes. Oligomeric Amyloid-β induces a divergent response in human vs. more...

(Submitter supplied) Microglia are involved in Alzheimer’s disease (AD) by adopting activated phenotypes. How ageing in the absence or presence of β-amyloid (Aβ) deposition in different brain areas affects this response and whether sex and AD risk genes are involved, remains however largely unknown. Here we analyzed the gene expression profiles of more than 10,000 individual microglia cells isolated from cortex and hippocampus of male and female AppNL-G-F at 4 different stages of Aβ deposition and in age-matched control mice. more...

(Submitter supplied) Loss-of-function variants of triggering receptor expressed on myeloid cells 2 (TREM2) increase the risk of developing Alzheimer's disease (AD). The mechanism through which TREM2 contributes to the disease (TREM2 activation vs inactivation) is largely unknown. Here, we analyzed changes in a gene set downstream of TREM2 to determine whether TREM2 signaling is modified by AD progression. We generated an anti-human TREM2 agonistic antibody and defined TREM2 activation in terms of the downstream expression changes induced by this antibody in microglia developed from human induced pluripotent stem cells (iPSC). more...
