Why the study?
Does D3 dopamine receptor activation regulate AT1 receptor expression in renal proximal tubule cells?
Does D3 dopamine receptor activation regulate AT1 receptor expression in renal proximal tubule cells?
D3 dopamine receptors directly interact with and downregulate AT1 receptor expression, providing a potential mechanism for hypertension related to decreased D3 receptor function.
