SG core exhibits higher protein concentration and reduced solvent capacity, causing autophagy receptors with specific stickers/spreader architecture to partition to the less dense peripheral shell phase. Receptors are 'squeezed out' to interface regions where solvent is more available. Skeptic identifies critical flaw: SQSTM1 and CALCOCO2 have multivalent domains predicted to partition INTO dense phases, contradicting the model. Partitioning physics predicts uniform shell distribution, not selec
**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
