Mice resistant to atherosclerosis can be engineered to develop the disease, creating models that mimic human atherosclerosis. These models aid in studying disease development and the impact of various factors on lesion progression.

Area of Science:

  • Cardiovascular Science
  • Genetics
  • Animal Models

Background:

  • Mice are naturally resistant to atherosclerosis.
  • Induced mutations can create atherosclerosis-susceptible mouse models.
  • Atherosclerotic lesions in mice can resemble human disease.

Purpose of the Study:

  • To review the development and utility of mouse models for atherosclerosis research.
  • To highlight genetic and environmental factors influencing lesion development.

Main Methods:

  • Genetic modification of mice (e.g., apolipoprotein E deficiency, low-density lipoprotein receptor deficiency).
  • Use of Western-type diets to exacerbate lesions.
  • Development of transgenic mice expressing human apolipoprotein B or mutant apolipoprotein E.

Main Results:

  • Apolipoprotein E-deficient mice develop human-like atherosclerotic lesions.
  • High-fat, high-cholesterol diets exacerbate lesions in susceptible mice.
  • Various genetically modified mouse models offer distinct advantages for studying atherosclerosis.

Conclusions:

  • Genetically modified mice are valuable tools for investigating atherosclerosis pathogenesis.
  • These models facilitate research into genetic, environmental, hormonal, and pharmacological influences on disease progression.
