American researchers have discovered a new type of cell in the heart that can help regulate its rhythm, according to the online edition Ericalert.
Researchers at the University of Notre Dame, Indiana, believe their findings may be important in understanding some types of congenital heart defects and other diseases of this organ.
The researchers found that when the newly discovered cells were removed, the heart rate increased. In cases where they are deprived of a key gene that controls their development, the heart begins to beat unevenly.
There is no clear connection between new cells and congenital heart defects, but they are where these health problems are found.
“We are not fully aware of the function of these cells, but the concept that if you remove them, the heart rate will increase, may link them to certain diseases,” said Dr. Cody Smith, a member of the research team.
According to him, “these glial cells can play a very important role in the regulation of the heart.”
Information about the discovery was published in the journal Public Labor in Science Biology.
