Journal of the Renin Angiotensin Aldosterone System is a peer-reviewed, open access journal published quarterly as a resource for biomedical professionals, including basic scientists and clinicians, primarily with an active interest in the renin-angiotensin-aldosterone system in humans and other mammals. It publishes original research articles and reviews on the normal and abnormal function of this system and its pharmacology and therapeutics, mostly in a cardiovascular context but including research in all areas where this system is present, including the brain, lungs, and gastro-intestinal tract. Although this is its main focus, JRAAS also publishes research on other peptides, such as vasopressin, the natriuretic peptides and the kallikrein-kinin system.
