Autophagy Enhancement via mTOR Inhibition for C9orf72 Dipeptide Repeat Pathology

Hypothesis

Autophagy Enhancement via mTOR Inhibition for C9orf72 Dipeptide Repeat Pathology

C9orf72 repeat expansions produce toxic dipeptide repeats (DPRs) that impair nucleocytoplasmic transport and autophagy.

🧪 Overview

C9orf72 repeat expansions produce toxic dipeptide repeats (DPRs) that impair nucleocytoplasmic transport and autophagy. mTOR inhibition via rapamycin may reduce DPR accumulation. However, rapamycin benefits in Drosophila C9 models did not translate well to mammals, and C9 ASO programs have failed clinically.
