Its development is hallmarked, among others, by the dysfunction and degeneration of<jats:italic>\u03b2<\/jats:italic>-cells of the pancreatic islets of Langerhans. The major pathological characteristic thereby is the formation of extracellular amyloid deposits consisting of the islet amyloid polypeptide (IAPP). The process of human IAPP (hIAPP) self-association, and the intermediate structures formed as well as the interaction of hIAPP with membrane systems seem to be, at least to a major extent, responsible for the cytotoxicity. Here we present a summary and comparison of the amyloidogenic propensities of hIAPP in bulk solution and in the presence of various neutral and charged lipid bilayer systems as well as biological membranes. We also discuss the cellular effects of macromolecular crowding and osmolytes on the aggregation pathway of hIAPP. Understanding the influence of different cellular factors on hIAPP aggregation will provide more insight into the onset of T2DM and help to develop novel therapeutic strategies.<\/jats:p>","DOI":"10.1155\/2015\/849017","type":"journal-article","created":{"date-parts":[[2015,10,25]],"date-time":"2015-10-25T21:02:43Z","timestamp":1445806963000},"page":"1-21","source":"Crossref","is-referenced-by-count":39,"title":["The
