This hypothesis is biologically plausible and potentially important for circuit-level phenotypes, but current support is stronger for contextual selectivity than for distinct intrinsic C1q biochemical programs at inhibitory versus excitatory terminals. It is more valuable for endpoint design and disease-stage interpretation than as a near-term therapeutic thesis.
## 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 ...
