(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) 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...

The discovery of genetic variants in the genes encoding Apolipoprotein E (APOE) and triggering receptor expressed on myeloid cells 2 (TREM2) as the strongest risk factors for Alzheimer’s disease (AD) highlights the importance of microglial biology in the brain. The sequence, structure and function of microglial proteins are poorly conserved across species, and this hampered the development of APOE and TREM2 targeting therapeutic strategies. more...

(Submitter supplied) TREM2 is a microglial-specific gene implicated in late-onset Alzheimer's Disease (AD). Recent studies have identified that Trem2-deficient mice exhibit transcriptional changes in microglial gene expression that minimize the upregulation of lipid metabolism and lysosomal genes in AD disease models. We detect similiarly attenuated expression of lipid metabolism genes in microglia isolated from brains of aged Trem2 knockout mice.

Recent studies have identified that Trem2-deficient mice exhibit transcriptional changes in microglial gene expression that minimize the upregulation of lipid metabolism and lysosomal genes in AD disease models. We find that chronic phagocytic challenge from demyelination generates similiarly attenuated expression of lysosomal and lipid metabolism genes in microglia isolated from Trem2 knockout mouse brain.
