Dying or stressed neurons release alpha-synuclein and DAMPs that activate microglia, which then generate superoxide through NOX2 and amplify TNF, IL1B, and NF-kB signaling. That extracellular ROS and cytokine field injures neighboring neurons, causing more aggregate release and renewed microglial activation. This best explains tissue-level spread and persistence rather than the earliest intracellular trigger.
## 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
