Vasoactive Intestinal Peptide (Vip, Vasoactive Intestinal Peptide)

Vasoactive Intestinal Peptide (Vip, Vasoactive Intestinal Peptide) is a protein that is produced by pancreatic cells. It has a pronounced effect on blood vessels. An increased content of this protein in the body can lead to the development of severe diarrhea.

Vasoactive Intestinal peptide was first isolated from pig intestinal tissue in 1970. It belongs to the family of vasoactive peptides, which play an important role in regulating the contraction of smooth muscles of blood vessels, bronchi, intestines and other organs.

The main biological effects of Vasoactive Intestinal Peptide are:

1. Relaxation of the smooth muscles of blood vessels, which leads to their dilation and increased blood flow.

2. Increased secretion of gastric juice, insulin and other hormones.

3. Regulation of intestinal motor function.

4. Participation in neurotransmission in the central and peripheral nervous system.

Thus, Vasoactive Intestinal Peptide plays an important role in the regulation of blood circulation, digestion, as well as a number of other physiological processes in the body. A change in the level of this peptide can lead to disorders of the cardiovascular, digestive and nervous systems.

Vasoactive Intestinal Peptide (Vip) is a protein that is produced by pancreatic cells and affects blood vessels. During research it was found that an increased content of this protein can lead to the development of severe diarrhea.

However, in addition to this, Vip performs many more important functions in the body. It is one of the key neuropeptides that regulate the functions of the gastrointestinal tract. Vip stimulates the secretion of gastric juice and bile, improves intestinal motility and increases blood flow in its walls.

In addition, Vip influences the body's immune system, regulating the processes of immune activation and antigen presentation. It is also involved in the regulation of cell growth and differentiation, as well as in the processes of apoptosis (programmed cell death).

Despite the wide range of functions that Vip performs, its most well-known effect is the regulation of vascular tone. Protein dilates blood vessels, which improves blood flow and lowers blood pressure. This effect makes Vip a valuable tool in the treatment of a number of diseases associated with circulatory disorders, such as arterial hypertension, coronary heart disease and some types of stroke.

It is important to note that Vip is not the only peptide that is involved in the regulation of blood circulation. One of the key players in this process is also angiotensin II, a protein that constricts blood vessels and increases blood pressure. This makes angiotensin II a major target in the treatment of hypertension.

In turn, Vip can be used to combat hypertension, especially in cases where angiotensin II is ineffective or causes side effects. However, before using Vip as a medicine, more research needs to be done to evaluate its effectiveness and safety.

In conclusion, Vip is a protein that is produced by pancreatic cells and has an effect on blood vessels. It is widely used in the treatment of various diseases related to poor circulation and has many other functions in the body. However, before using Vip as a medicine, more research needs to be done to evaluate its effectiveness and safety.

Peptides: what are they?

Peptides are protein substances consisting of two or more amino acid residues connected by peptide (amide or amine) bonds. A characteristic feature of the structure of peptides is their low molecular weight: most often from 500 to 10 thousand Yes. A feature of the structure of peptides is the presence of a quaternary (heterotetrameric or
