In the walls of blood vessels has been identified protein Responsible for regulating blood pressure. According to experts, this discovery should help to develop new treatments for people suffering from high blood pressure.

At the head of the research was Ian Greenwood - Doctor from the University of St. George in London. Together with colleagues, he carried out experiments on mice, which are proof that the basic function of expansion and contraction of the arteries performs protein Kv7.4.

This protein regulates a potassium channel, which opening is passed potassium   from muscle cells blood vessels . Thus, potassium is responsible for contraction or muscle relaxation, which is the controlling factor. Defects of this protein can lead to an increase in pressure, and the latter is the cause stroke Heart attacks and diseases kidney .

According to the researchers, cases of disorders associated with potassium channel protein in people with increased blood pressure are rare. However, they believe that the understanding of the mechanism of action of the polypeptide is very important, because it may be useful to develop methods of medical influence on blood pressure .
