Imaging of pancreatic islet cells

PET probes for imaging pancreatic islet cells

Imaging pancreatic islet cells by positron emission tomography

It was estimated that every year more than 30000 persons in the United States - approximately 80 people per day - are diagnosed with type 1 diabetes (T1D). T1D is caused by autoimmune destruction of the pancreatic islet (β cells) cells. Islet transplantation has become a promising therapy option for T1D patients, while the lack of suitable tools is difficult to directly evaluate of the viabilit...

HISTOLOGICAL AND IMMUNOHISTOCHEMICAL STUDY OF PANCREATIC ISLET BETA CELLS OF DIABETIC RATS TREATED WITH ORAL VANADYL SULPHATE

Vanadium salts have been suggested as a possible therapeutic agent for the treatment of diabetes. The aim of the present study was to clarify histological and immunohistochemical changes that occur in the pancreatic beta (β) cells of vanadyl sulphate (VS)-treated streptozotocin (STZ) induced diabetic rats. Male Wi star rats were made diabetic by injecting a single intravenous dose of STZ (...

Protein-Mediated Interactions of Pancreatic Islet Cells

The islets of Langerhans collectively form the endocrine pancreas, the organ that is soley responsible for insulin secretion in mammals, and which plays a prominent role in the control of circulating glucose and metabolism. Normal function of these islets implies the coordination of different types of endocrine cells, noticeably of the beta cells which produce insulin. Given that an appropriate...

Donor Islet Endothelial Cells in Pancreatic Islet Revascularization

OBJECTIVE Freshly isolated pancreatic islets contain, in contrast to cultured islets, intraislet endothelial cells (ECs), which can contribute to the formation of functional blood vessels after transplantation. We have characterized how donor islet endothelial cells (DIECs) may contribute to the revascularization rate, vascular density, and endocrine graft function after transplantation of fres...
