Why the study?
Does dopamine D3 receptor activation alter renal response differently in spontaneously hypertensive rats compared to normotensive rats?
Does dopamine D3 receptor activation alter renal response differently in spontaneously hypertensive rats compared to normotensive rats?
Dopamine D3 receptor activation induces a uniform renal response and shows similar gene expression in both spontaneously hypertensive and normotensive rats, suggesting it is not involved in the pathogenesis of hypertension in this model.

Equivalent natriuresis with D3 activation in SHR versus WKY; hypothesis-generating and does not inform clinical hypertension management.
Luippold et al. (2003) studied this question.
