Presently there are no registered drugs which change the deposition of amyloid and there are no drugs with convincing effect on the progression of the disease in patients with Alzheimer's. Moreover the drugs which have been marketed for treatment have a disadvantageous side effect profile. Besides insulin, β-cells secrete amylin, amyloid or IAPP (islet amyloid polypeptide) and these thus share certain characteristics with β-amyloid. Previously IAPP was considered to be non-toxic but recent studies have indicated a possible conversion to toxic β-amyloid.
