Angiotensin II-(3-8)-hexapeptide, at the dose of 1 nmol given intracerebroventricularly, only slightly less than angiotensin II (the same dose and route) stimulated exploratory locomotor behaviour in an open field and electromagnetic motimeter. Both peptides considerably enhanced stereotyped behaviour produced by

The angiotensin AT(4) receptor was originally defined as the specific, high affinity binding site for the hexapeptide angiotensin IV (Ang IV). Subsequently, the peptide LVV-hemorphin 7 was also demonstrated to be a bioactive ligand of the AT(4) receptor. Central administration

In this work we compared in rats the influence of heptapeptide 1-7-angiotensin II, hexapeptide 2-7-angiotensin II, pentapeptide 3-7-angiotensin II and angiotensin II on motility, stereotypy, learning of conditioned avoidance responses and recall of passive avoidance behaviour allowing to avoid aversive

This study demonstrates the existence of a previously unrecognized class of angiotensin binding sites on vascular smooth muscle that exhibit high affinity and specificity for the hexapeptide (3-8) fragment of angiotensin II (AngIV). Binding of [125I]AngIV is saturable, reversible and

The biological activity of des-asp1-des-arg2-angiotensin II (3-8AII) was studied in man. When 3-8AII was infused iv at rates of 22 and 308 pmol (17.5 and 250 ng)/kg . min separately into 5 normal men each for 120 min, blood pressure
