Central nervous system myelination requires recognition and signalling processes between neuronal axons and oligodendrocytes. Complex cellular rearrangements occur in myelination-competent oligodendrocytes requiring spatio-temporal control mechanisms. Although the molecular repertoire is becoming increasingly transparent, the signalling mechanisms governing myelination initiation are only poorly understood. The non-receptor tyrosine kinase Fyn has been implicated in axon-glial signal transduction and in several cellular processes required for oligodendrocyte maturation and myelination. Here, we review oligodendroglial Fyn signalling and discuss the role of Fyn in axon-glia interaction mediating myelination.
中枢神经系统髓鞘形成需要神经元轴突和少突胶质细胞之间的识别和信号转导过程。髓鞘形成能力的少突胶质细胞中会发生复杂的细胞重排,这需要时空控制机制。尽管分子谱正在变得越来越透明,但髓鞘形成起始的信号转导机制仍知之甚少。非受体酪氨酸激酶 Fyn 已被牵连到轴突-胶质细胞信号转导以及少突胶质细胞成熟和髓鞘形成所需的几种细胞过程中。在这里,我们回顾了少突胶质细胞 Fyn 信号,并讨论了 Fyn 在介导髓鞘形成的轴突-胶质相互作用中的作用。
