DOI: 10.1007/s00216-020-02560-5
Abstract: Type 2 diabetes is characterized by the aggregation of human islet amyloid polypeptide (hIAPP), from monomer to amyloid deposits that are made of insoluble fibrils. Discrepancies concerning the nature of formed species or oligomerization kinetics… read more here.
