| Research Abstract |
Moyamoya disease is characterized by a progressive stenosis at the terminal portion of the internal carotid artery and an abnormal vascular network at the base of the brain. We investigated the role of regulatory T-cell (Treg) in the patho-physiology of moyamoya disease. Result showed that number of Foxp3-positive Treg was significantly lower in patients with moyamoya disease compared to normal control. We also compared the expression of Foxp3-positive Treg between mice lacking RNF213 (susceptibility gene for moyamoya disease) and wild-type mice, but there was no significant difference. These results suggested that autoimmune response mediated by Treg may play a role in the patho-physiology of moyamoya disease.
