This article discusses how to use dynamic light scattering to monitor protein aggregation.

A novel system to control protein aggregation in a model of Parkinson's disease may answer longstanding questions about how the disease begins and spreads, according to a new study published March 9th in the open-access journal PLOS Biology by Abid Oueslati of Laval University, Quebec, Canada, and colleagues.

The aggregation of proteins into inclusions or plaques is a prominent hallmark of a diverse range of pathologies including neurodegenerative diseases. The quantification of such inclusions in Caenorhabditis elegans models of aggregation is usually achieved by fluorescence microscopy or other techniques involving biochemical fractionation of worm lysates. Here, we describe a simple and rapid flow cytometry-based approach that allows fluorescently tagged inclusions to be enumerated in whole worm l...

The maintenance of cellular protein homeostasis, or proteostasis, is dependent upon a complex network of molecular chaperones, degradation machinery and other regulatory factors, which together act to keep the proteome soluble and functional. Disturbances to proteostasis can lead to protein aggregation and inclusion formation, processes associated with a variety of neurodegenerative disorders. The heat shock proteins (Hsps) are a superfamily of molecular chaperones that are dramatically upregula...
