The gap can be tested by treating tight-junction remodeling as an upstream driver rather than a passive correlate. If true, perturbing dynamic contrast MRI should shift CSF/serum albumin ratio before downstream neurodegeneration markers change.
## 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...

The INVOKE-2 trial (AL002, TREM2 agonist) failed to meet primary endpoints in 2024. This raises questions about mechanism appropriateness, off-target effects from systemic activation, and whether amyl...

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...
