**Molecular Mechanism and Rationale**
The pathogenesis of Parkinson's disease (PD) involves complex interactions between peripheral inflammatory signals and central nervous system neurodegeneration, with the toll-like receptor 4 (TLR4)/myeloid differentiation primary response 88 (MyD88)/nuclear factor kappa B (NF-κB) signaling axis serving as a critical mechanistic bridge. Lipopolysaccharide (LPS), a gram-negative bacterial endotoxin abundantly present in the gut microbiome, becomes systemicall
## 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
