abstract = {Amyloid deposits consisting of fibrillar islet amyloid
polypeptide (IAPP) in pancreatic islets are associated with
beta-cell loss and have been implicated in type 2 diabetes
(T2D). Here, we applied cryo-EM to reconstruct densities of
three dominant IAPP fibril polymorphs, formed in vitro from
synthetic human IAPP. An atomic model of the main polymorph,
built from a density map of 4.2-Å resolution, reveals two
S-shaped, intertwined protofilaments. The segment
21-NNFGAIL-27, essential for IAPP amyloidogenicity, forms
the protofilament interface together with Tyr37 and the
amidated C terminus. The S-fold resembles polymorphs of
Alzheimer's disease (AD)-associated amyloid-β (Aβ)
fibrils, which might account for the epidemiological link
between T2D and AD and reports on IAPP-Aβ cross-seeding in
vivo. The results structurally link the early-onset T2D IAPP
genetic polymorphism (encoding Ser20Gly) with the AD Arctic
mutation (Glu22Gly) of Aβ and support the design of
inhibitors and imaging probes for IAPP fibrils.},
