The rejection of islets of Langerhans following intrahepatic transplantation in the rat. 1976

D Slater, and Y Mangnall, and A Smythe, and M Fox

Pancreatic acinar tissue and islets of Langerhans have been isolated using a collagenase technique from Agus rats and transplanted separately into the liver of diabetic and nondiabetic isogeneic Agus and allogenic PVG/C rats. Livers were removed on days 1, 2, 4, 7 and 14 and examined histologically. Transplanted isogeneic islets showed no evidence of cellular infiltration and the beta cells appeared fully granulated. Transplanted allogeneic islets in non-diabetic recipients were surrounded by a mononuclear cellular infiltrate on day 2 and this became maximal by day 4. Although initially fully granulated, beta cells became degranulated on day 7 and by day 14 only small fragments of islet tissue remained. In allogeneic diabetic recipients the cellular infiltrate appeared less dense; beta cells appeared incompletely granulated from days 1 to 4 and a transient fatty degeneration occurred in the hepatic parenchuma around islets.

UI	MeSH Term	Description	Entries
D007515	Islets of Langerhans	Irregular microscopic structures consisting of cords of endocrine cells that are scattered throughout the PANCREAS among the exocrine acini. Each islet is surrounded by connective tissue fibers and penetrated by a network of capillaries. There are four major cell types. The most abundant beta cells (50-80%) secrete INSULIN. Alpha cells (5-20%) secrete GLUCAGON. PP cells (10-35%) secrete PANCREATIC POLYPEPTIDE. Delta cells (~5%) secrete SOMATOSTATIN.

D008099	Liver	A large lobed glandular organ in the abdomen of vertebrates that is responsible for detoxification, metabolism, synthesis and storage of various substances.	Livers
D010179	Pancreas	A nodular organ in the ABDOMEN that contains a mixture of ENDOCRINE GLANDS and EXOCRINE GLANDS. The small endocrine portion consists of the ISLETS OF LANGERHANS secreting a number of hormones into the blood stream. The large exocrine portion (EXOCRINE PANCREAS) is a compound acinar gland that secretes several digestive enzymes into the pancreatic ductal system that empties into the DUODENUM.
D003920	Diabetes Mellitus	A heterogeneous group of disorders characterized by HYPERGLYCEMIA and GLUCOSE INTOLERANCE.
D006084	Graft Rejection	An immune response with both cellular and humoral components, directed against an allogeneic transplant, whose tissue antigens are not compatible with those of the recipient.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
