Renin

Renin is a peptidase enzyme that is produced by the kidneys and plays an important role in regulating blood pressure. In this article we will look in more detail at what renin is, how it affects the body, and what problems can arise when it is produced in excess.

Renin is a key component of the renin-angiotensin system (RAS), which regulates blood pressure and blood volume in the body. Renin is produced by special cells located in the kidneys called juxtaglomerular cells. These cells respond to changes in the circulatory system, such as decreased blood pressure or decreased blood volume, and begin to release renin into the bloodstream.

Renin acts on the liver-produced protein angiotensinogen, which is found in the blood, and converts it into angiotensin I. This process is called angiotensin formation. Angiotensin I is then converted to a more active form, angiotensin II, by another enzyme, angiotensin-converting enzyme (ACE). Angiotensin II causes blood vessels to constrict, which increases blood pressure in the body.

The role of renin in regulating blood pressure is very important. However, excess renin production can cause problems. For example, renal hypertension syndrome is a disease that is associated with excessive production of renin. It manifests as high blood pressure that does not respond to treatment with antihypertensive drugs. Treatment for this disease may use renin inhibitors or angiotensin-converting enzymes, which help reduce the level of renin in the body.

In conclusion, renin is an enzyme that plays an important role in regulating blood pressure. It is produced by the kidneys and helps convert angiotensinogen into active angiotensin II, which causes blood vessels to constrict. Excessive production of renin can lead to problems such as renal hypertension syndrome. Treatment of this disease may include the use of renin inhibitors or angiotensin-converting enzymes.



Renin is an enzyme secreted by the kidneys and plays an important role in regulating blood pressure. This enzyme is responsible for breaking down angiotensinogen, which is synthesized by the liver, and converting it into angiotensin-1. Angiotensin-1, in turn, is converted to angiotensin-2, which causes blood vessels to constrict. This leads to increased blood pressure in the body.

However, excess renin can lead to the syndrome of renal hypertension, which can be associated with various kidney diseases. Therefore, it is important to monitor the level of renin in the blood and, if necessary, take measures to normalize it.
