Research Interest

 Dr. Andresen’s research interests are focused on G protein-coupled receptors (GPCRs) within the cardiovascular system.  He studies two independent events: Angiotensin II signaling within renal vascular smooth muscle cells, which are proposed to be involved in hypertension; and the molecular mechanism of GPCR kinase 4 gamma (GRK4γ)-mediated inhibition of Gs-coupled receptors, polymorphisms in GRK4γ are implicated in hypertension.  Dr. Andresen is also interested in GPCR research in general and is interested in deorphanizing GPCRs; he is currently working on identifying the C-peptide receptor.
