A credible refinement is that any true amplification is not universal across cell types, but emerges most strongly in professional phagocytes with high endogenous LRRK2 activity, chronic cargo load, and active endolysosomal remodeling. This would reconcile modest blood-cell baseline effects with larger functional consequences in microglia/macrophages relevant to inflammatory and trafficking phenotypes.
## 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

The main weakness across all six is the same: most cited evidence shows that mutant `LRRK2` can elevate phospho-Rab output or alter lysosomal remodeling, but it does **not** cleanl...
