Neurons affected by dysfunctional thyroid.
Copyright: Mittag et al.
Scientists at Karolinska Institutet, in collaboration with colleagues in Germany and the Netherlands, have identified a previously unknown group of nerve cells in the brain. The nerve cells regulate cardiovascular functions such as heart rhythm and blood pressure. It is hoped that the discovery, which is published in the Journal of Clinical Investigation, will be significant in the long term in the treatment of cardiovascular diseases in humans. The scientists have managed to identify in mice a previously totally unknown group of nerve cells in the brain. These nerve cells, also known as 'neurons', develop in the brain with the aid of thyroid hormone, which is produced in the thyroid gland. Patients in whom the function of the thyroid gland is disturbed and who therefore produce too much or too little thyroid hormone, thus risk developing problems with these nerve cells. This in turn has an effect on the function of the heart, leading to cardiovascular disease.
