Streptozotocin-induced pancreatic insulitis in mice. Morphologic and physiologic studies. 1978

A A Like, and M C Appel, and R M Williams, and A A Rossini

Pancreatic insulitis and diabetes mellitus were induced in Charles River CD-1 mice with five subdiabetogenic injections of streptozotocin. Plasma glucose and immunoreactive insulin levels were measured and animals were sacrificed at intervals for morphologic studies of pancreatic islets and measurements of extractable pancreatic immunoreactive insulin. Light microscopy revealed striking insulitis, 5 to 6 days after streptozotocin injections, with cell necrosis and eventual islet atrophy due to beta-cell necrosis, and numerous type C viruses within many of the surviving beta-cells. Light microscopic immunoperoxidase stains of islet cell hormones and electron microscopy identified relatively increased numbers of alpha- and delta-cells within the atrophic islets 6 and 12 months after streptozotocin injections. Plasma glucose, plasma immunoreactive insulin, and extractable pancreatic immunoreactive insulin measurements documented the persistence of profound hyperglycemia, as well as the reduction of plasma and pancreatic immunoreactive insulin levels. Immunofluorescence studies demonstrated the absence of circulating islet cell antibodies during both the acute and chronic stages of the syndrome. The pathogenesis of this model of insulin-deficient diabetes is believed to be a cell-mediated autoimmune reaction directed against pancreatic beta-cells altered by subdiabetogenic injections of streptozotocin. The importance of the increased number of type C viruses within surviving beta-cells remains obscure.

D007249 Inflammation A pathological process characterized by injury or destruction of tissues caused by a variety of cytologic and chemical reactions. It is usually manifested by typical signs of pain, heat, redness, swelling, and loss of function. Innate Inflammatory Response,Inflammations,Inflammatory Response, Innate,Innate Inflammatory Responses
D007328 Insulin A 51-amino acid pancreatic hormone that plays a major role in the regulation of glucose metabolism, directly by suppressing endogenous glucose production (GLYCOGENOLYSIS; GLUCONEOGENESIS) and indirectly by suppressing GLUCAGON secretion and LIPOLYSIS. Native insulin is a globular protein comprised of a zinc-coordinated hexamer. Each insulin monomer containing two chains, A (21 residues) and B (30 residues), linked by two disulfide bonds. Insulin is used as a drug to control insulin-dependent diabetes mellitus (DIABETES MELLITUS, TYPE 1).

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.

D008214 Lymphocytes White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS. Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell
D008264 Macrophages The relatively long-lived phagocytic cell of mammalian tissues that are derived from blood MONOCYTES. Main types are PERITONEAL MACROPHAGES; ALVEOLAR MACROPHAGES; HISTIOCYTES; KUPFFER CELLS of the liver; and OSTEOCLASTS. They may further differentiate within chronic inflammatory lesions to EPITHELIOID CELLS or may fuse to form FOREIGN BODY GIANT CELLS or LANGHANS GIANT CELLS.

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.
