Casein kinase 2 (CK2)-mediated hyperphosphorylation of G3BP1 at specific serine/threonine residues alters the tunable switch mechanism, converting transient LLPS into irreversible coacervates that nucleate protein aggregation.
**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
