Along with reference 28, this work indicated that chaperones, which are known to disrupt protein aggregates, switch to actively create aggregates of high molecular mass when the concentration of the aggregating protein is high. These papers thus established the idea that active aggregation can be protective.

The threshold for polyglutamine-expansion protein aggregation and cellular toxicity is dynamic and influenced by aging in Caenorhabditis elegans. Proc. Natl Acad. Sci. USA 99, 10417-10422 (2002). This seminal study indicated that the minimal number of polyQ repeats that is needed to enable aggregation declines with age. It also showed that a reduction in IIS protects worms from polyQ aggregation.

This report indicated that reduced IGF signalling is typical in the offspring of centenarians and suggested that the regulation of lifespan by IGF signalling is conserved in humans. It also showed that high IGF plasma levels can lead to reduced IGF signalling, supporting the idea that feedback loops regulate the IIS pathway.
