Abstract

The effect of pressure on the aggregation ability of proteins is summarized in this paper. It is shown that pressure counteracts the formation of intermolecular β-structure, which is the main structural form in conformational diseases. Already slight pressurization to typically 2 kbar can destabilize aggregates. On the other hand, the intermediate state formed after high pressure treatment, has increased tendency for aggregation. It is shown that pressure is an appropriate tool for the studying the formation and the stability of aggregates.
