SUMMARY

# Proposed experiment from debate on Microglia activate astrocytes via IL-1alpha/TNF/C1q, and reactive astrocytes fee ## Background and Rationale This falsification experiment investigates whether PLIN2 (perilipin-2) overexpression in reactive astrocytes contributes to neuroinflammation through altered lipid droplet metabolism and inflammatory lipid production. PLIN2 is a lipid droplet-associated protein that regulates intracellular lipid storage and metabolism, and its upregulation in reactive

METHODOLOGY NOTES

**Phase 1: Cell Culture Preparation (Days 1-3)** • Maintain primary mouse microglia and astrocytes in separate cultures using DMEM/F12 + 10% FBS • Transfect astrocytes with PLIN2-overexpression plasmid or empty vector control (n=6 wells per condition) • Generate conditional PLIN2 knockdown astrocytes using siRNA transfection (50 nM, Lipofectamine 3000) • Verify transfection efficiency by qPCR and Western blot at 48h post-transfection • Establish co-culture system with 1:1 ratio of microglia:astrocytes in 24-well plates **Phase 2: Inflammatory Stimulation (Day 4)** • Stimulate microglia with LPS (100 ng/ml) + IFN-γ (20 ng/ml) for 6h to induce M1 activation • Collect conditioned medium from activated microglia • Apply microglial conditioned medium (50% v/v) to astrocyte cultures • Include positive control: direct IL-1α (10 ng/ml) + TNF-α (10 ng/ml) + C1q (1 μg/ml) treatment • Sample collection timepoints: 0h, 6h, 12h, 24h, 48h post-stimulation **Phase 3: Lipidomics Analysis (Days 5-7)*
