[Advance in pathogenesis of oligodendrocytes-associated autism spectrum disorder].
摘要
Autism spectrum disorder (ASD) is a serious neurodevelopmental impairment of children. Because of its difficulty of early diagnosis, length of disease course, irreversible injury and slim chance of curability, it brings heavy burdens to patients, their families and the whole society. Recent studies have shown that the pathogenic mechanism of ASD is closely related to the abnormal myelination caused by the imbalance of differentiation, proliferation and apoptosis of oligodendroglial lineage cells. This article will review on the role of oligodendroglial lineage cells in myelination and the mechanisms of ASD caused by improper differentiation, proliferation and apoptosis of oligodendroglial lineage cells, according to advanced researches. Oligodendrocytes play vital roles in neurodevelopment, and the defect in these cells has been recognized as one of the key pathogenic mechanisms leading to ASD. Elucidating the effects and disciplines which oligodendrocytes exert on the occurrence and development of ASD would provide guidance for precise prevention and control of neurodevelopmental disorders such as ASD.
