How do pathological stress granules in neurodegeneration escape TRIM21/autophagy-mediated clearance?

PARTIALLY ADDRESSED

The study shows TRIM21 and autophagy receptors can eliminate both physiological and pathological SGs, yet persistent stress granules are hallmarks of ALS/FTD. The mechanisms by which disease-associated SGs evade this clearance system remain unclear but are critical for therapeutic targeting. Gap type: open_question Source paper: Stress granule homeostasis is modulated by TRIM21-mediated ubiquitination of G3BP1 and autophagy-dependent elimination of stress granules.
