Immune attack on pancreatic islet transplants in the spontaneously diabetic BioBreeding/Worcester (BB/W) rat is not MHC restricted. 1985

E J Weringer, and A A Like

Spontaneous diabetes mellitus in the BB/W rat is preceded by lymphocytic insulitis that destroys pancreatic beta cells. Cultured pancreatic islets and adrenal cortex from inbred rats of variable MHC were transplanted to RT1/u BB/W rats without allograft rejection. Islet grafts from RT1/u and non-RT1/u rats evidenced lymphocytic insulitis in BB/W recipients that became diabetic or evidenced lymphocytic insulitis within endogenous islets. These findings suggest that BB immune insulitis is not MHC restricted and may be directed against islet transplants from non-RT1/u animals.

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.

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

D006649 Histocompatibility Antigens A group of antigens that includes both the major and minor histocompatibility antigens. The former are genetically determined by the major histocompatibility complex. They determine tissue type for transplantation and cause allograft rejections. The latter are systems of allelic alloantigens that can cause weak transplant rejection.
