Project description:Preparation of primary microglial cultures from postnatal mice is tedious with a low yield, high variability and risk of astrocytic contamination. Microglia derived from embryonic stem cells (ESdM) have been suggested as alternative source, but it is unclear how closely ESdM resemble the molecular phenotype of primary microglia. Here, we performed a whole transcriptome analysis of ESdM in comparison to primary cultured and flow cytometry-sorted microglia and compared the microglial transcriptome to other cell types. Cultured microglia and ESdM were related to sorted microglia, but clearly distinct from other myeloid cell types, T cells, astrocytes and neurons. ESdM and primary cultured microglia showed strong overlap in their transcriptome. Only 144 gene transcripts were differentially expressed between both cell types, mainly derived from immune-related genes with a higher activation status of pro-inflammatory and immune defense genes in primary microglia compared to ESdM. Flow cytometry analysis of cell surface markers CD54, CD74 and CD274 selected from the microarray confirmed the close phenotypic relation between ESdM and primary cultured microglia. Thus, assessment of genome-wide transcriptional regulation demonstrates that microglia are distinct from other macrophage cell types and that mouse pluripotent stem cell-derived microglia are closely related to cultured postnatal microglia.

Project description:Understanding microglial states in the aging brain has become crucial, especially with the discovery of numerous Alzheimer’s disease (AD) risk and protective variants in genes such as INPP5D and TREM2, which are essential to microglia function in AD. Here we present a thorough examination of microglia-like cells and primary mouse microglia at the proteome and transcriptome levels to illuminate the roles these genes and the proteins they encode play in various cell states. First, we compared the proteome profiles of wildtype and INPP5D (SHIP1) knockout primary microglia. Our findings revealed significant proteome alterations only in the homozygous SHIP1 knockout, revealing its impact on the microglial proteome. Additionally, we compared the proteome and transcriptome profiles of commonly used in vitro microglia BV2 and HMC3 cells with primary mouse microglia. Our results demonstrated a substantial similarity between the proteome of BV2 and mouse primary cells, while notable differences were observed between BV2 and human HMC3. Lastly, we conducted targeted lipidomic analysis to quantify different phosphatidylinositols (PIs) species, which are direct SHIP1 targets, in the HMC3 and BV2 cells. This in-depth omics analysis of both mouse and human microglia enhances our systematic understanding of these microglia models.

Project description:Microglia, the resident immune cells of the brain, can exhibit a broad range of activation phenotypes, many of which have been implicated in several diseases and disorders of the central nervous system including alcohol use disorders and disorders. By utilizing a method optimized for sensitive and rapid quantitative proteomic analysis of microglia involving suspension trapping (S-Trap), we were able to produce efficient and reproducible protein extraction from low cell yielding primary mouse brains. Using a ~2 h gradient on a 75 cm UPLC column with a modified data dependent acquisition method on a hybrid quadrupole-Orbitrap mass spectrometer (QE Plus), 5,062 total proteins were identified where 4,928 of those proteins were quantifiable by label-free quantitation (with 5 biological replicates). This analysis resulted in the most comprehensive proteomic dataset for ethanol- and LPS-treated primary mouse microglia to date and even expanded upon the well-characterized macrophage/microglia response to LPS treatment. This study also highlights the subtle, yet significant changes ethanol exposure can induce when compared to control. Interestingly, these changes are not consistent with the robust classical activation induced by LPS treatment, but instead align with the emerging theory that ethanol-treated microglia yield an alternative activation response. The contrast to LPS-treated microglia leads us to conclude that ethanol does not elicit a strong inflammatory response but rather might have a general inhibitory effect on multiple pathways such as phagocytosis and cell migration.

Project description:The microarray transcriptome analysis of primary microglia was performed to demonstrate a direct modulation of NGF activity on microglia cells. The three different time points were used to evaluate and describe the time course of genes patwhays. In summary this experiment was crucial to describe for the first time the kind of NGF activity on microglia.
