Novel aspects of angiotensin AT1 receptor signalling pathways

Abstract

Hormones are chemicals released into the blood to influence tissue function by binding to specific sites (receptors) located on the cells found in a particular tissue. In general, it has been considered that a specific receptor activates a specific response when bound by the hormone. However, it is now clear that closely related hormones can activate different patterns of response even when they bind the one type of receptor. The full consequence of this phenomenon is still unknown. Its significance will be investigated in this project for important hormones which are involved in blood pressure control. The renin-angiotensin system makes the hormone angiotensin II which increases blood press..
