Metabolic disease models – db/db Mouse Model
Use the gold-standard db/db mouse model of type 2 diabetes mellitus (T2DM) and obesity in your preclinical research
Db/db Mouse Model Characteristics
The db/db mouse model (also referred to as Leprdb) is the most widely used rodent model for characterizing metabolic and histological effects of type 2 diabetes mellitus (T2DM) drugs. Due to spontaneous monogenic mutation in the leptin receptor, the db/db mouse model is characterized by severe obesity, hyperphagia, polyuria hyperinsulinemia, insulin resistance, and hyperglycemia. At InnoSer, we have additionally shown that the leptin-deficient db/db mice show specific deficits in learning and cognitive flexibility (e.g., via battery of behavioral tests such as Morris Water Maze or Spontaneous Behavior in the PhenoTyperTM Automated Home-Caging System), in line with previous research in this model.
The phenotypic characteristics make the db/db mouse model an ideal research tool for investigating efficacy of novel therapeutics in the setting of obesity, metabolic disorders, diabetic complications, and even T2DM-associated cognitive dysfunctions which is currently an emerging area of research in the metabolic disease field. Contact us today to discuss how this model can support your therapeutic development efforts.
✓ Studies are run using the homozygous leptin-deficient db/db (Leprdb) with heterozygous db+ (Leprdb/+) serving as controls.
✓ The model is characterized by severe obesity, hyperglycemia, hyperinsulinemia and hyperphagia.
✓ Mice show cognitive impairments.
As a preclinical metabolic CRO, InnoSer’s team delivers you with a range of high-quality in vivo models for key metabolic diseases with different associated risk factors and aetiologias. This selection allows you to test therapeutic efficacy to prevent or reverse insulin resistance, pre-diabetes, obesity type 2 diabetes mellitus (T2DM), and/or MAFLD/MASH (NASH/NAFLD). To study metabolic disease-associated cardiovascular complications and cardiac dysfunction, InnoSer recommends the use of the Western diet-induced diabetic cardiomyopathy rat model.

Db/db Mouse Model Sample Data

The db/db mouse model represents a gold-standard mouse model for metabolic disease research.
Compared to the leptin-deficient heterozygous db+ mice, the db/db mice develop basal hyperglycemia, suitable model for studying efficacy of novel therapeutics on established diabetes.

The db/db mouse model represents a gold-standard mouse model for metabolic disease research.
Compared to the leptin-deficient heterozygous db+ mice, the db/db mice have significantly higher body weight suitable obesity.
