Protein aggregation and its pathological effects are the major cause of several neurodegenerative diseases. In Huntington's disease an elongated stretch of polyglutamines within the protein Huntingtin leads to increased aggregation propensity. This induces cellular defects, culminating in neuronal loss, but
