1. Auxiliary Cells for the Vascularization and Function of Endogenous and Transplanted Islets of Langerhans
Sammanfattning : Type 1 diabetes develops through the progressive destruction of the insulin-producing beta-cells. Regeneration or replacement of beta-cells is therefore needed to restore normal glucose homeostasis. Presently, normoglycemia can be achieved by the transplantation of whole pancreas or isolated islets of Langerhans. LÄS MER
Sammanfattning : Based on the discovery of a new amino acid transport system in Langerhans cells (LC), various aspects concerning the L-dopa uptake mechanism into human epidermal LC and the energy metabolism of epidermis have been examined and subsequently characterised. The system lacks any characteristics of other described amino acid transport systems in other cell types. LÄS MER
Sammanfattning : ABSTRACT The cancer immunosurveillance hypothesis postulates that the immune system can recognize cancer cell precursors and destroy those cells before a clinical manifestation occurs. During the last decades several groups have presented evidence of the influence and role of immune activation in oral squamous cell carcinoma (OSCC) patients; however, much less is known about the role of immune activation in potentially malignant oral disorders (PMOD).

Sammanfattning : Transplantation of insulin producing cells is currently the only cure for type 1 diabetes. However, even though the Edmonton protocol markedly increased the success rate of pancreatic islet transplantation, the long term insulin independence is still very poor. An adequate engraftment is critical for islet graft survival and function. LÄS MER
Sammanfattning : The blood vessels of the pancreatic islets are of crucial importance for oxygen and metabolite supply as well as dispersal of secreted hormones. In addition to this, endothelial cells have an important role in the revascularization process after islet transplantation. LÄS MER
