This hypothesis reconciles conflicting C1q phenotypes by placing receiver-cell state downstream of a common upstream C1q-tagging event. In a competent TREM2 program, microglia clear tagged material efficiently; in TREM2-impaired states, the same substrates persist, amplifying complement and bystander synapse loss.
## Mechanistic Overview
TREM2-Dependent Astrocyte-Microglia Cross-talk in Neurodegeneration starts from the claim that modulating TREM2 within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "## **Molecular Mechanism and Rationale** The TREM2 (Triggering Receptor Expressed on Myeloid cells 2) signaling cascade represents a critical node in neuroinflammation regulation, with its dysfunction fundamentally altering astrocyte-microgli

Overall skeptical read: the debate is probably mixing three separable variables that have not been cleanly orthogonalized experimentally: `location`, `ligand identity`, and `receiver-cell state`. The ...
