**Molecular Mechanism and Rationale** The pathological aggregation of TAR DNA-binding protein 43 (TDP-43) represents a critical hallmark of numerous neurodegenerative disorders, including amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), and limbic-predominant age-related TDP-43 encephalopathy (LATE). Under physiological conditions, TDP-43 functions as a nuclear RNA-binding protein that regulates transcription, splicing, and mRNA stability. However, in disease states, TDP-43 u

## Molecular Mechanism and Rationale Stress granules (SGs) are membraneless, phase-separated ribonucleoprotein organelles that form through liquid-liquid phase separation in response to cellular stress, representing a critical intersection between RNA metabolism and neuroinflammation in neurodegenerative diseases. The formation and persistence of pathological stress granules is orchestrated primarily by G3BP1 (GTPase-activating protein SH3 domain-binding protein 1) and its paralog G3BP2, which
