1. 1. Islet amyloid polypeptide (IAPP) in Type 2 diabetes and Alzheimer disease

   Författare :Marie Oskarsson; Gunilla Westermark; Mikael Oliveberg; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; amyloid; IAPP; Abeta; type 2 diabetes; Alzheimer disease; BRICHOS; heparan sulfate; islet amyloid; amyloid plaques; seeding; Medical Cell Biology; Medicinsk cellbiologi;

   Sammanfattning : The misfolding and aggregation of the beta cell hormone islet amyloid polypeptide (IAPP) into amyloid fibrils is the main pathological finding in islets of Langerhans in type 2 diabetes. Pathological assemblies of IAPP are cytotoxic and believed to contribute to the loss of insulin-producing beta cells. LÄS MER

3. 2. Accumulation and Cellular Clearance of IAPP and Proteotoxicity of ATTR in Drosophila Models

   Författare :Xiaohong Gu; Gunilla Westermark; Anders Olofsson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; amyloid; IAPP; ATTR; ATTR amyloidosis; crystalline structure; aggrephagy; Drosophila melanogaster; Gal4-UAS; electron tomography; DAMS; SOHA; Medical Cell Biology; Medicinsk cellbiologi;

   Sammanfattning : Proteins’ functions are dependent on their three-dimensional (3D) structure. Under certain circumstances, proteins misfold and form aggregates, sometimes leading to amyloidosis. Islet amyloid polypeptide (IAPP) builds up amyloid in the pancreatic islet of patients with type 2 diabetes (T2D).

4. 3. Studies of neuropeptides in pancreatic beta cell function with special emphasis on islet amyloid polypeptide (IAPP)

   Författare :Ella Karlsson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; alpha cell; amylin; beta cell; chromogranin; growth; IAPP; insulin; islet amyloid polypeptide; leptin; NOD mice; pancreastatin; pancreatic islet; proliferation; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

   Sammanfattning : The presence of protein amyloid in pancreas and its association to diabetes was first described 100 years ago in 1901, but was not identified as Islet Amyloid Polypeptide (IAPP) until 1986. The aim of the present work was to determine the role of the beta cell hormone, IAPP, in normal pancreatic islet physiology and during early disturbances of islet function. LÄS MER

5. 4. Islet amyloid polypeptide (IAPP) : Mechanisms of Amyloidogenesis in the Pancreatic Islets and Potential Roles in Diabetes Mellitus

   Författare :Zhi Ma; Arne Andersson; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : Islet amyloid is the most common characteristic feature of the islets in type 2 diabetes, being found in up to 90% of diabetic patients at post-mortem. lt has as its unique component the islet beta-cell peptide islet amyloid polypeptide (IAPP), which is eo-secreted with insulin.

7. 5. Islet Amyloid Polypeptide: Interaction with Amyloid Beta, Alpha-Synuclein and BRICHOS

   Författare :Ye Wang; Gunilla Westermark; Ludmilla Morozova-Roche; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; amyloid; IAPP; Abeta; alpha-synuclein; Bri2 BRICHOS; luminescent conjugated oligothiophenes; Medical Cell Biology; Medicinsk cellbiologi;

   Sammanfattning :  Amyloid, the congophilic deposits of misfolded protein, are pathological hallmarks of many common diseases, among others, Alzheimer’s disease (AD), Parkinson’s disease (PD), and type 2 diabetes (T2D). Amyloid beta (Aβ) forms senile plaques in AD, alpha-synuclein (aSyn) forms Lewy bodies and Lewy neurites in PD, islet amyloid polypeptide (IAPP) forms islet amyloid in T2D. LÄS MER
