Cardiovascular complications in diabetes: lessons from animal models

Area of Science:

• Cardiovascular Research
• Diabetology
• Animal Models in Medicine

Background:

• Diabetic micro- and macro-vascular complications significantly contribute to morbidity and mortality in patients with type 1 and type 2 diabetes.
• The molecular underpinnings of individual susceptibility to diabetic cardiovascular injury remain largely unknown, despite established links between metabolic abnormalities and cardiovascular lesions.

Purpose of the Study:

• To provide an overview of key animal models used in diabetes research.
• To highlight the contributions of these models to understanding the pathogenesis of cardiovascular complications in diabetes.
• To discuss the advantages and limitations of animal models in studying diabetic cardiovascular disease.

Main Methods:

• Review of existing literature on animal models of diabetes.
• Analysis of data from various rodent and larger animal models (rabbits, cats, pigs, monkeys).
• Evaluation of distinct phenotypes across different diabetic models to understand disease mechanisms.

Main Results:

• Animal models, while not perfect replicas of human diabetes, offer a controlled environment to study genetic and environmental risk factors.
• Studies in animal models have elucidated molecular mechanisms involved in the development, progression, and therapeutic control of diabetes-related cardiovascular issues.
• Different models provide unique insights into specific aspects of diabetic cardiovascular complications, necessitating a multi-model approach.

Conclusions:

• A comprehensive understanding of diabetic cardiovascular complications requires evaluating diverse animal models.
• Animal studies are essential for dissecting the complex molecular pathways contributing to cardiovascular injury in diabetes.
• Continued research using well-characterized animal models is vital for advancing therapeutic strategies for diabetic cardiovascular disease.
