Endocrine hypertension, angiotensin receptors, renal paracrine hormones
An international expert on subjects related to hypertension, Dr. Siragy was the first to discover that stimulation of angiotensin AT2 receptor leads to generation of nitric oxide. Siragy has authored more than 250 medical journal articles and abstracts, and numerous medical textbook chapters, including a chapter on the kidney and the renin angiotensin system in the Braunwald Atlas of Heart Diseases; a chapter on angiotensin and diabetic nephropathy in Harrison's on-line textbook of Medicine; and a chapter on the angiotensin receptor in Hypertension: A Companion to Brenner. Dr Siragy's primary research interests are in the areas of the renin-angiotensin system, cardiac ischemia, diabetic nephropathy and (Pro)Renin receptor.
