Salt-sensitive rats are a commonly used animal model in research studies that investigate the effects of high salt intake on blood pressure regulation and the development of hypertension. These rats are genetically predisposed to developing high blood pressure in response to a high salt diet, making them valuable tools for studying the mechanisms underlying salt-induced hypertension. By studying salt-sensitive rats, researchers can gain insights into the pathophysiology of hypertension and identify potential new targets for therapeutic interventions. Additionally, these rats are used to test the effectiveness of various anti-hypertensive drugs and interventions. Overall, salt-sensitive rats play a crucial role in advancing our understanding of the relationship between salt intake and hypertension.
