Experimental models in diabetes research

Area of Science:

• Endocrinology and Metabolism
• Pharmacology and Toxicology

Background:

• Diabetes mellitus is a significant global health issue affecting over 11% of adults, with many cases undiagnosed.
• The complex pathogenesis of diabetes necessitates ongoing research for advanced therapeutic strategies.
• Experimental models are crucial for dissecting disease mechanisms and assessing interventions, though no single model perfectly mirrors human diabetes.

Purpose of the Study:

• To review and compare various experimental models used in diabetes research.
• To highlight the strengths, limitations, and translational relevance of different modeling platforms.
• To guide the rational selection of experimental models for efficient diabetes research and therapeutic innovation.

Main Methods:

• Review of evidence from diverse experimental platforms including chemical, dietary, genetic, and in vitro models.
• Analysis of models simulating beta-cell loss (streptozotocin, alloxan).
• Evaluation of models reflecting insulin resistance and metabolic disturbances (dietary, obesity-induced, ob/ob, db/db mice).
• Consideration of in vitro systems for mechanistic studies and drug screening.

Main Results:

• Chemical models (streptozotocin, alloxan) mimic beta-cell destruction.
• Dietary, obesity-induced, and genetic models (ob/ob, db/db) offer insights into insulin resistance, obesity, and autoimmune aspects.
• In vitro systems facilitate controlled mechanistic investigations and high-throughput drug screening.
• Each model type presents unique advantages and disadvantages for studying specific facets of diabetes.

Conclusions:

• Diverse experimental models are essential for advancing diabetes research and therapeutic development.
• Understanding the comparative strengths and limitations of each model is key to selecting the most appropriate platform.
• Rational model selection can significantly enhance the efficiency and translational success of diabetes research.
