摘要: Background—The renin-angiotensin system and especially the angiotensin peptides play a central role in blood pressure regulation. Here, we hypothesize that an as-yet unknown peptide is involved action of II modulating vasoregulatory effects as cofactor. Methods Results—The with vasodilatory properties was isolated from adrenal glands chromatographically. The this were evaluated vitro vivo, receptor affinity analyzed. plasma concentration humans quantified patients chronic kidney disease, heart failure, healthy control subjects. amino acid sequence bovine HSSYEDELSEVL EKPNDQAE PKEVTEEVSSKDAAE, which degradation product chromogranin A. human HSGFEDELSEVLENQSSQAELKEAVEEPSSKDVME. Both diminished significantly vasoconstrictive effect vitro. Therefore, named t...
