Islet inflammation in type 2 diabetes and physiology
The Journal of Clinical Investigation
|January 4, 2017
Summary
Inflammation in type 2 diabetes (T2D) involves islet macrophages releasing inflammatory cytokines, causing beta cell dysfunction. Targeting this islet inflammation may offer new therapeutic strategies for metabolic diseases.
Area of Science:
- Immunology
- Endocrinology
- Metabolic Diseases
Background:
- Islet inflammation and beta cell dysfunction are key features of type 2 diabetes (T2D).
- Intra-islet macrophages increase in T2D and are primary sources of proinflammatory cytokines.
- Targeting islet inflammation shows therapeutic potential in human T2D studies.
Purpose of the Study:
- To review the cellular and molecular mechanisms of islet inflammation in T2D.
- To examine the role of macrophage polarity in T2D pathology and beta cell health.
- To highlight potential therapeutic strategies for improving islet function.
Main Methods:
- Literature review of cellular and molecular mechanisms.
- Analysis of macrophage polarization in islet inflammation.
- Discussion of translational implications for T2D therapeutics.
Main Results:
- Islet inflammation, driven by macrophages, contributes significantly to beta cell dysfunction in T2D.
- Macrophage polarization dynamics within islets are crucial in T2D.
- Understanding these mechanisms can guide the development of novel T2D treatments.
Conclusions:
- Islet inflammation is a critical factor in type 2 diabetes pathogenesis.
- Modulating macrophage behavior within islets presents a promising therapeutic avenue.
- Further research into islet inflammation and macrophage polarity can advance T2D treatment strategies.

4.0K
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

01:27Glucose Homeostasis: Pancreatic Islets and Insulin Secretion
2.9K
The pancreatic islets comprising only 1%-2% of the volume are highly vascularized and innervated mini-organs. They contain five endocrine cell types, including β cells that secrete insulin, which is synthesized as a single polypeptide chain, preproinsulin, processed to proinsulin, and finally to insulin and C-peptide. This process is complex and regulated, involving the Golgi complex, the endoplasmic reticulum, and the secretory granules of the β cell.

Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

5.3K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

01:05Insulin Secretory Vesicles
7.2K
Insulin secretory vesicles release insulin to stimulate blood glucose uptake and regulate carbohydrate metabolism. When the blood glucose levels increase, glucose enters the pancreatic β-islet cells through glucose transporters. Once inside, glucose is metabolized through glycolysis, the citric acid cycle, and the electron transport chain, producing ATP. This increase in ATP concentration closes ATP-sensitive potassium channels, leading to depolarization of the membrane and the opening of...
