WebAug 1, 2012 · Abstract. The aspartyl protease renin is the rate limiting activity of the renin–angiotensin–aldosterone system (RAAS). Renin is synthesized as an enzymatically inactive proenzyme which is constitutively secreted from several tissues. Only renin-expressing cells in the kidney are capable of generating active renin from prorenin, … Specifically, renin secretion happens when: Baroreceptors (pressure-sensitive receptors) in your arterial vessels detect low blood pressure. Your kidneys detect low salt (sodium) levels. Beta 1 adrenergic receptors (which regulate your heart rate) detect activity in your sympathetic nervous system. Does renin … See more Increased renin levels are linked to several conditions, including: 1. Hypotension (low blood pressure). 2. Blood loss. 3. Lack of blood flow to your kidneys. 4.
