What is the definition of bradykinin? What are the effects of bradykinin on the human body?
Bradykinin is a small peptide that is produced in the body and plays a crucial role in the physiological response to injury and inflammation. It is a part of the kinin family of peptides, which are known for their powerful effects on the human body. In this article, we will discuss the definition of bradykinin and the effects of bradykinin on the human body.
Bradykinin is a nonapeptide, meaning it is made up of nine amino acids. It is produced in the body by the breakdown of a larger protein called kininogen. Once produced, bradykinin is then released into the bloodstream where it can bind to receptors in various tissues and organs.
Bradykinin is best known for its vasodilator effects, which means it causes the blood vessels to widen or dilate. This increase in blood flow can help to reduce blood pressure and improve blood flow to injured or inflamed areas. This is why bradykinin is often associated with the "flush" response that occurs after injury, when blood vessels dilate and blood flow increases to the affected area.
In addition to its vasodilator effects, bradykinin also has a number of other effects on the human body. It can also increase the production of mucus in the respiratory tract, which can help to protect the lungs from injury and infection. It can also increase the permeability of blood vessels, which can allow more immune cells to migrate to the site of injury or infection.
Bradykinin also has pain-relieving properties. It stimulates the release of other pain-relieving compounds called prostaglandins, which can reduce pain and inflammation. This is why bradykinin is also associated with the "inflammatory response" that occurs after injury, when pain and inflammation increase in the affected area.
Bradykinin also has a number of other effects on the human body. For example, it can also promote the release of hormones such as insulin and antidiuretic hormone, which can help to regulate blood sugar and fluid balance in the body. It can also promote the release of other chemicals such as histamine, which can cause an allergic reaction.
Bradykinin is also known to play a role in the development of some diseases. It is involved in the progression of hypertension and has a role in the development of angioneurotic edema, a rare genetic disorder characterized by recurrent episodes of swelling in the face, tongue, throat, and hands. It is also thought to play a role in the development of cancer, particularly in the lungs, colon and prostate.
In conclusion, bradykinin is a small peptide that plays a crucial role in the physiological response to injury and inflammation. It is best known for its vasodilator effects, which can help to reduce blood pressure and improve blood flow to injured or inflamed areas. It also has a number of other effects on the human body, such as increasing the production of mucus in the respiratory tract, increasing the permeability of blood vessels, and promoting the release of other pain-relieving compounds. However, excessive bradykinin production can contribute to some diseases such as hypertension, angioneurotic edema, and cancer. It's important to consult with a healthcare professional to determine if it's appropriate to use drugs or other treatment that modulate bradykinin levels.
