1. Microencapsulation of Pancreatic Islets : A Non-Vascularised Transplantation Model
Sammanfattning : Transplantation of pancreatic islets is a potential treatment of type 1 diabetes that aims to restore normal blood glucose control. By encapsulating the islets in alginate, they can be protected from rejection. LÄS MER
2. Studies of neuropeptides in pancreatic beta cell function with special emphasis on islet amyloid polypeptide (IAPP)
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
3. Islet hormonal hypersecretion and metformin’s effect on islet hormonal secretion studied in vitro and in vivo
Sammanfattning : Childhood obesity has surged globally. Elevated levels of free fatty acids contribute to hyperinsulinemia, hyperproinsulinemia, and hyperglucagonemia connected with both obesity and type 2 diabetes mellitus (T2DM). Metformin has beneficial effects on islets by influencing metabolism and reducing stress-induced cell death. LÄS MER
4. CFTR in pancreatic islets
Sammanfattning : AbstractCystic fibrosis (CF) is caused by mutations in the anion channel and protein regulator CFTR. The most common co-morbidity in CF is CF-related diabetes (CFRD) affecting ~50% of adult patients. The etiopathology of CFRD is largely unknown but the destruction of the exocrine pancreas is thought to contribute. LÄS MER
5. Studies of the human pancreas to understand the pathologic events leading to type 1 diabetes
Sammanfattning : Type 1 diabetes (T1D) is classically described as a disease emanating from beta-cell loss, and as such, the beta cells have been the main target of investigation. However, recent years have witnessed a shift in perspective, with T1D being increasingly recognized as a condition that affects the entire pancreas. LÄS MER
