| Study Title | Microglial and Non-Microglial Regulation of Lipid Metabolism in Alzheimer's Revealed by Genetic and Pharmacological Depletion |
| Study Summary | Abnormal lipid metabolism is observed in Alzheimer’s disease (AD), but its contribution to disease progression remains unclear. Genetic studies indicate that microglia, the brain’s resident immune cells, influence lipid processing during AD. Here we show that, in both mouse models of AD and human postmortem brain tissue, microglia regulate the accumulation of specific lipids associated with disease pathology. Using multidimensional mass spectrometry-based shotgun lipidomics and histological analysis, we find that arachidonic acid-containing bis(monoacylglycero)phosphate (BMP) accumulates in response to amyloid plaques, and this buildup depends on microglial function and the AD risk gene progranulin (GRN). In contrast, lysophosphatidylcholine (LPC) and lysophosphatidylethanolamine (LPE) accumulate independently of microglia, instead associating with astrocyte activation and oxidative stress. These findings connect dysregulated lipid metabolism in AD to distinct brain cell types and molecular pathways. The results suggest that microglial regulation of lipid homeostasis is a potential therapeutic target for AD. |

Collection:
| Collection ID: | CO004196 |
| Collection Summary: | This study includes lipidomic profiling of cerebrum from mouse models and BA-38 from postmortem human brain samples. Mouse right hemi-cerebra were dissected out, placed in cryotubes, and flash-frozen in liquid nitrogen. Human BA-38 samples were obtained from brain bank, received as frozon tissue. Frozen brains (both mice and human) were lyophilized using a benchtop freeze dryer (Labconco, Kansas City, MO, USA) under 0.5 vacuum for 48 hours. Lyophilized brain samples were weighted and transferred to Precellys 0.5 ml tubes pre-filled with small beads. Dried tissues were powdered using Precellys® Evolution Tissue Homogenizer (Bertin technologies, Montigny-le-Bretonneux, France) through one round of manufacture’s “soft program” at 0 °C. Powdered dry cerebrum tissues were weighted around 5mg for lipidomics using disposable anti-static spatulas. Dried and powdered tissues were homogenized in 0.1X PBS. Protein concentrations were measured using a bicinchoninic acid (BCA) assay. |

| Treatment ID: | TR004212 |
| Treatment Summary: | 5xFAD mice (Tg(APPSwFlLon,PSEN1*M146L*L286V)6799Vas/Mmjax), were obtained from the Mutant Mouse Resource and Research Center (MMRRC) at The Jackson Laboratory in two different genetic backgrounds (B6SJL: MMRRC_034840-JAX; and C57BL6: MMRRC_034848-JAX). Mice were housed under 12/12 h light/dark cycles with free access to food and water ad libitum. Only female mice were used for the pharmacological (PLX5622-treated) partial microglial elimination cohorts and both male and female mice were used for the genetic (FIRE) full microglial elimination cohort. For the long-term pharmacological group, 1,200 mg of PLX5622 (free base)/kg was added to OpenStandard Diet (OSD) with 15 kcal% fat (Research diets, INC., New Brunswick, NJ, USA). Control mice were fed with OSD, and experimental mice with OSD+ PLX5622 from 6 weeks of age until 5 months when tissues were harvested. For the short-term pharmacological group, 1,200 mg of PLX5622 (free base)/kg was added to OpenStandard Diet (OSD) with 15 kcal% fat (Research diets, INC., New Brunswick, NJ, USA). Control mice were fed with OSD, and experimental mice with OSD+ PLX5622 from 6 weeks of age until 8 weeks when tissues were harvested. |
Sample Preparation:
| Sampleprep ID: | SP004209 |
| Sampleprep Summary: | Lipid extraction from the homogenates, standardized by protein content, employed a modified Bligh and Dyer procedure with added internal standards. Lipid quantification was achieved using triple-quadrupole and orbitrap mass spectrometers (Thermo Fisher Scientific, Waltham, MA, USA), both coupled with a Nanomate device (Advion, Ithaca, NY, USA) and controlled by the Xcalibur system. Data processing, including ion peak selection, baseline correction, data transfer, peak intensity comparison 13C deisotoping, and quantitation, was facilitated by a custom-programmed Microsoft Excel macro as previously described, ensuring accurate analysis of lipid molecular species. |
