Huntington's disease doesn't just poison your cells; it literally strangles them with a "knitted fabric" made of toxic protein.

Fragile polyQ assemblies cause Golgipathy in Huntington's disease

The Takeaway
We used to think the protein aggregates in Huntington’s were just disorganized heaps of "cellular trash." This research shows they actually form complex, "knitted-fabric" structures that physically wrap around and cripple the Golgi apparatus—the cell's vital shipping center. Once this "fabric" cages the Golgi, the cell can no longer move proteins where they need to go to survive. It’s a mechanical death by a thousand cuts rather than just a chemical toxin. This discovery suggests we shouldn't just be looking for "antidotes," but ways to physically "unravel" the mesh that is choking our neurons.
From the abstract
Huntingtin (HTT) is a naturally aggregating protein that causes Huntington's disease (HD) when its polyglutamine (polyQ) tract exceeds 38 repeats. Despite its importance, the biology of HTT aggregates remains poorly defined. Utilizing high-resolution imaging of HD family-derived cells, we have redefined polyQ assemblies that were formerly viewed as pathogenic aggregates and as dynamic structures resembling knitted-fabric patches. These assemblies encircle the Golgi apparatus, integrating ribbons
