TL;DR
It is suggested that mutant Htt does not reduce CMA activity and that enhancing CMA activity to clear mutant Htt may be a novel strategy for the management of HD.
A previously unrecognized modulatory role of wt-C9orf72 in regulating mHTT aggregation in experimental HD models is identified and a novel wt-C9orf72-Stat1-Isg15 axis is identified, providing new insights into wt-C9orf72-associated protein homeostasis.
It is shown that CMA is active in NSCs, while expression of LAMP2A, the principal limiting component of CMA, is associated with the induction of neurogenesis, and it is demonstrated that LAMP2A is involved in NSC fate decisions by interfering with NOTCH1 signaling pathway.
These findings support the value of preclinical models for translational studies, and autophagy enhancement as a potential therapeutic strategy for HSPB8-related myopathy, and evaluated trehalose, a natural disaccharide that induces HSPB8 and enhances autophagy.
Findings identify USP28 as a proteostasis-associated deubiquitinase reduced in HD models and suggest that USP28 deficiency contributes to ubiquitin burden and mHTT aggregation.
Through targeted genetic knock-down, huntingtin is identified as a cell-autonomous regulator of neuropeptide trafficking, neuronal excitability and circadian output and carries direct relevance for HD therapeutic strategies, particularly those involving huntingtin-lowering approaches.
The RNA-binding protein YTHDC1 is identified as an ATP-independent molecular chaperone that prevents harmful protein aggregation, revealing a link between RNA regulation and protein quality control in neurodegeneration.
