Summary
Animal models are crucial for understanding type 2 diabetes (T2D) and testing treatments. This review details various models, including genetically modified ones, and their use in preclinical drug testing.
Area of Science:
- Endocrinology and Metabolism
- Pharmacology
- Animal Science
Background:
- Type 2 diabetes (T2D) affects over 100 million globally, presenting significant health and economic challenges.
- Understanding T2D pathogenesis, complications, and risk factors requires robust experimental models.
- Current research necessitates effective models for evaluating novel therapeutic agents.
Purpose of the Study:
- To provide a comprehensive overview of available animal models for type 2 diabetes research.
- To discuss the characteristics, origins, and mechanisms of various T2D animal models.
- To evaluate the suitability of these models for preclinical testing of new chemical entities (NCEs).
Main Methods:
- Review of spontaneous, induced, and genetically modified animal models of T2D.
- Analysis of model origins, features, and underlying mechanisms.
- Assessment of model advantages and disadvantages for research and drug development.
Main Results:
- Diverse animal models exist, including spontaneous, chemically induced, and genetically engineered (transgenic, knockout) mice.
- Each model offers unique insights into T2D pathogenesis and complications.
- Specific models demonstrate utility in preclinical evaluation of NCEs for T2D treatment.
Conclusions:
- Appropriate selection of animal models is critical for advancing type 2 diabetes research.
- Genetically modified models offer powerful tools for dissecting T2D complexity.
- Animal models are indispensable for the preclinical assessment of new diabetes therapies.

01:26Type II Diabetes I: Introduction
Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder characterized by insulin resistance, in which target tissues such as the liver, muscle, and adipose tissue respond poorly to insulin. It is also associated with inadequate compensatory insulin secretion, where pancreatic β-cells fail to produce sufficient insulin. Together, these abnormalities lead to persistent hyperglycemia.EtiologyT2DM develops through a complex interaction of genetic predisposition and environmental or...
01:24Type II Diabetes II: Pathophysiology
PathophysiologyType 2 diabetes mellitus (T2DM ) is a chronic metabolic disorder characterized by insulin resistance and progressive pancreatic β-cell dysfunction, leading to impaired glucose homeostasis. It results from interactions among genetic predisposition, environmental factors, and metabolic stressors, such as overnutrition and a sedentary lifestyle.Insulin Resistance and Glucose DysregulationEarly T2DM involves insulin resistance in skeletal muscle, adipose tissue, and the liver.
01:22Diabetes Mellitus: Type 2 and Gestational
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...
01:22Diabetes Mellitus: Overview and Type I Subtype
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...

01:26Type I Diabetes II: Pathophysiology
Type 1 diabetes mellitus arises from an immune-mediated destruction of pancreatic β-cells, resulting in an absolute deficiency of insulin. This process develops in genetically susceptible individuals when autoimmunity, environmental exposures, and immunologic dysregulation converge to trigger a targeted attack on the insulin-producing cells of the pancreas. The β-cells are located within the islets of Langerhans and are essential for regulating blood glucose by facilitating cellular uptake of...
01:36Carbohydrate Metabolism
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 the...
