The Dahl salt-sensitive rat is a widely used animal model in hypertension research. These rats are genetically predisposed to develop high blood pressure in response to a high-salt diet. They exhibit many similarities to human essential hypertension, making them a valuable tool for studying the mechanisms and potential treatments for hypertension. Researchers can use these rats to investigate the complex interactions between genetic and environmental factors that contribute to hypertension and to test potential pharmacological interventions. The Dahl salt-sensitive rat model has been instrumental in advancing our understanding of hypertension and developing new treatments for this common and dangerous condition.
