The same signal may be beneficial early and damaging late. Testing proteasome shuttle failure with autophagy flux rescue should reveal a disease-stage interaction and define when intervention is protective versus counterproductive.
## 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

Based on the provided literature, TREM2 is a microglial surface receptor governing the disease-associated microglia (DAM) program. The TREM2 R47H loss-of-function variant increases Alzheimer's risk ~3...

TREM2 biology is highly stage-dependent. In early AD, TREM2 activation promotes amyloid clearance via DAM. In late AD, DAM may become senescent and contribute to chronic inflammation. Biomarker guidan...
