ABSTRACT

High pressure research can be used to aid in answering why some polypeptide chains reversibly unfold and others adopt a misfolding conformation culminating in aggregation. This topic is one of the fundamental questions in biology that we seek to understand, and for that, we have been experimentally applying pressure to proteins for the last 20 years. Here, we exemplify how pressure research should be used to identify preamyloidogenic protein intermediates as well as to dissociate supramolecular complexes. We believe that the applications of high pressure to understand the behavior of proteins are diverse and can help biologists answer fundamental questions of biomedical relevance.
