SUMMARY

# s:** - GPR32 knockout in microglia should worsen neuroinflammation if this is the primary mechanism - Dose-response studies showing therapeutic window ## Background and Rationale This falsification study rigorously tests the hypothesis that GPR32 serves as a protective receptor in microglial-mediated neuroinflammation by examining the consequences of receptor loss in controlled cellular models. The experiment employs CRISPR-Cas9 gene editing to generate GPR32 knockout BV2 microglia cell lines,

METHODOLOGY NOTES

**Phase 1: Cell Line Preparation and Genetic Modification (Days 1-14)** • Generate GPR32 knockout BV2 microglial cell lines using CRISPR-Cas9 system with dual guide RNAs targeting exons 2 and 3 • Validate knockout efficiency by Western blot, qPCR, and sequencing (n=3 independent clones) • Maintain wild-type BV2 controls and establish stable cell cultures in DMEM + 10% FBS • Prepare immortalized human microglial cell line (HMC3) as secondary validation model **Phase 2: Neuroinflammation Induction Protocol (Days 15-16)** • Treat cells with LPS (0.1, 1.0, 10 μg/mL) + IFN-γ (20 ng/mL) for 24h to induce neuroinflammation • Include ATP (5 mM, 30 min) treatment for NLRP3 inflammasome activation • Establish co-culture system with primary neurons (DIV 7-10) to assess neuronal damage • Include vehicle controls and unstimulated baseline conditions **Phase 3: Dose-Response Analysis (Days 17-21)** • Test GPR32 agonist RvD1 at concentrations: 0.1, 1, 10, 100 nM, 1 μM over 4h and 24h timepoints • A
