## **Molecular Mechanism and Rationale**
The hexanucleotide repeat expansion (GGGGCC) in the C9orf72 gene represents the most prevalent genetic cause of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), accounting for approximately 40% of familial ALS cases and 25% of familial FTD cases. This expansion undergoes repeat-associated non-ATG (RAN) translation, generating five distinct dipeptide repeat proteins (DPRs): poly-glycine-proline (poly-GP), poly-glycine-arginine (poly-
## 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
