摘要:

许旺细胞的发育、成熟和再生是多条细胞内信号通路协调作用的结果,其中涉及的分子包括整合素、神经调节蛋白、生长因子、激素、神经递质,以及整个胞内途径,包括蛋白激酶(PK)A,C,AKT,ERK/MAPK,Hippo,mTOR等、例如,Hippo途径参与器官大小控制的总体增殖、凋亡、再生和,是癌增殖过程中至关重要的因素之一。在许旺细胞中,Hippo与merlin和YAP/TAZ信号通路有关,其似乎可响应于机械/物理损害。最近,在众多调节许旺细胞的因素中,一种信号传导Src酪氨酸激酶和粘着斑激酶(FAK)被证明与许旺细胞有关,参与其粘附、运动、迁移和体外髓鞘形成的调节。在许旺细胞中, Src和FAK受神经活性类固醇别孕烯醇酮调节,起到控制许旺细胞成熟的作用。文中综述了许旺细胞在不同的发育、成熟和再生状态下,一些信号转导途径在调节许旺细胞生物学和功能方面的作用。

Abstract:

nervous system, require the coordinate and complementary interaction among several factors, signals and intracellular pathways. These regulatory molecules consist of integrins, neuregulins, growth factors, hormones, neurotransmitters, as well as entire intracellular pathways including protein-kinase A, C, Akt, Erk/MAPK, Hippo, mTOR, etc. For instance, Hippo pathway is overall involved in proliferation, apoptosis, regeneration and organ size control, being crucial in cancer proliferation process. In SCs, Hippo is linked to merlin and YAP/TAZ signaling and it seems to respond to mechanic/physical challenges. Recently, among factors regulating SCs, also the signaling intermediates Src tyrosine kinase and focal adhesion kinase (FAK) proved relevant for SC fate, participating in the regulation of adhesion, motility, migration and in vitro myelination.In SCs, the factors Src and FAK are regulated by the neuroactive steroid allopregnanolone, thus corroborating the importance of this steroid in the control of SC maturation. In this review, we illustrate some old and novel signaling pathways modulating SC biology and functions during the different developmental,mature and regenerative states
