G3BP1's RGG domain undergoes reversible arginine methylation that tunes its liquid-liquid phase separation behavior. PRMT1-mediated hypermethylation in disease states favors gel/solid phases. Pharmacological PRMT1 inhibition could restore physiological G3BP1 phase behavior. However, PRMT1 methylates hundreds of substrates, and G3BP1 hypermethylation in disease has not been directly demonstrated.
**Background and Rationale** TREM2 variants represent major genetic risk factors for Alzheimer's disease, with loss-of-function mutations increasing dementia risk threefold. While TREM2 is exclusively expressed on microglia, emerging evidence suggests its primary pathogenic role occurs through disrupted astrocyte-microglia communication rather than intrinsic microglial dysfunction. Healthy brain homeostasis depends on coordinated responses between these glial populations, where TREM2+ microglia
