Both AD and T2D are amyloidogenic conditions; Aβ (1–40 and 1–42) is found at increased concentrations in AD and amylin (islet amyloid polypeptide, IAPP) is found at elevated levels within insulin resistant states (Cooper et al., 1989; Hardy and Higgins, 1992; Lim et al., 2010). The gene discussed is IAPP; the disease is type 2 diabetes mellitus.
