Type 1 diabetes (T1D), formerly known as juvenile diabetes, is an autoimmune disease that occurs when the body's immune system destroys pancreatic cells (beta cells). [5] In healthy persons, beta cells produce insulin. Insulin is a hormone required by the body to store and convert blood sugar into energy. [6]
Prediabetes –; Main types of diabetes: Type 1 diabetes – disease that results in autoimmune destruction of insulin-producing beta cells of the pancreas. [4]Type 2 diabetes – metabolic disorder that is characterized by high blood glucose in the context of insulin resistance and relative insulin deficiency.
IDDM11 (insulin-dependent diabetes mellitus 11) is one of the susceptibility genes for IDDM which locates on chromosome 14q24.3-q31. [ 2 ] [ 6 ] This loci is identified by linkage to D14S67 marker via a sibling-pair linkage analysis [ 2 ] [ 6 ] Based on the previous study, the biological behavior of IDDM11is different to HLA region genes so ...
The insulin transduction pathway is a biochemical pathway by which insulin increases the uptake of glucose into fat and muscle cells and reduces the synthesis of glucose in the liver and hence is involved in maintaining glucose homeostasis.
Diabetes mellitus type 1 is caused by insufficient or non-existent production of insulin, while type 2 is primarily due to a decreased response to insulin in the tissues of the body (insulin resistance). Both types of diabetes, if untreated, result in too much glucose remaining in the blood (hyperglycemia) and many
Firstly, the full-length GLP-1 (1–37) was found to be catalysed by endopeptidase to the biologically active GLP-1 (7–37). Secondly, the glycine corresponding to proglucagon (108) was found to serve as a substrate for amidation of the C-terminal arginine resulting in the equally potent GLP-1 (7–36) amide. In humans, almost all (>80% ...
There are about 1 million islets distributed throughout the pancreas of a healthy adult human. While islets vary in size, the average diameter is about 0.2 mm. [5]:928 Each islet is separated from the surrounding pancreatic tissue by a thin, fibrous, connective tissue capsule which is continuous with the fibrous connective tissue that is interwoven throughout the rest of the pancreas.
Diabetes mellitus can be experimentally induced in vivo for research purposes by streptozotocin [34] or alloxan, [35] which are specifically toxic to beta cells. Mouse and rat models of diabetes also exist including ob/ob and db/db mice which are a type 2 diabetes model, and non-obese diabetic mice (NOD) which are a model for type 1 diabetes. [36]
