Awesome Cardiovascular (Student) Research!!!
  1. Regulation by adrenal G protein-coupled receptor kinases & beta-arrestins of catecholamine (i.e. adrenaline & noradrenaline) production by the adrenal gland in heart failure
  2. Regulation by adrenal G protein-coupled receptor kinases & beta-arrestins of aldosterone production by the adrenal cortex in heart failure and hypertension
  3. Exploration of strategies (involving G protein-coupled receptor kinases & beta-arrestins) to increase cardiac function by enhancing beta2-adrenergic receptor signaling and function in the cardiac muscle
  4. Role of beta-arrestin-dependent angiotensin II-aldosterone axis in regulation of function of stem cells used for heart failure therapy
  5. Development of novel beta-arrestin "biased" agonist and antagonist drugs for angiotensin II type 1 receptors
  6. Role of adrenal beta-arrestin-dependent angiotensin II-aldosterone axis in hypertension and stroke
  7. Role of lung beta-arrestin in glucocorticoid receptor function with implications for asthma drug therapy

Dr. Lymperopoulos is also collaborating with the University Federico II in Naples, Italy (Dr. Rengo`s & Dr. Leosco`s groups), Temple University in Philadelphia, PA (Dr. Koch`s group), the University of Florida in Gainesville, FL (Dr. Sumner`s group), and the University of Miami Miller School of Medicine (Dr. Hare`s group).
