What is a vasoactive intestinal peptide?
vasoactive intestinal peptide, or VIP, is a hormone that was originally discovered in the intestine, but since then it has found that it has occurred throughout the body. As hormones of the digestive system they allow VIP relaxation of muscles in the intestine, reduce food absorption and stomach production and increase the amount of water in digestive juices. The vasoactive intestinal peptide also has effects on the brain, heart, lungs, reproductive and immune systems. It is involved in the regulation of sleep, embryos development and endocrine or hormone control. Drugs that mimic or block the effects of VIP could have the potential to treat many different diseases. It causes its effects to bind to vasoactive intestinal peptide receptor on the cell in the target tissue. The name vasoactive intestinal peptide was created because scientists found the hormone for the first time in the extracts taken from the intestine, and it has shown that it affects blood vessels, causing them to spread or spread. VIP also acts to rest smooth muscles in the intestine, including muscle in the walls of the stomach and yellowlearning and muscle valve or sphincter on the bottom of the esophagus.
In the lungs causes vasoactive intestinal peptide of the airway extension. It can suppress the immune system and has a number of actions in the brain. The endocrine system is controlled by the hypothalamus in the brain and the VIP can be released along with other hypothalamic hormones, which affects the system as a whole. In the nervous system, VIP hormones transmit signals along the nerve paths. It is believed that vasoactive intestinal peptide can affect the behavior and sleep patterns, and the hormone can affect the course of diseases such as cancer and Alzheimer.
A rare type of cancer tumor known for the pancreatic can sometimes develop a vipoma. The tumor secretes a large amount of vasoactive intestinal peptide, causing symptoms such as diarrhea, which is watery and may occur in large quantities. Other symptoms may include pain and cramps in the abdomen, weight loss and nausea and rinse the popularityCHECKED.
Excessive diarrhea associated with VIPoma usually leads to dehydration. Treatment initially includes patient rehydration by giving fluids through a vein, along with drugs to control diarrhea. The tumor can then be surgically removed. If VIPOME can be removed before it has a chance to spread, the view is positive and the patient may be cured.
