Chondroitin sulfate/dermatan sulfate (CS/DS) proteoglycans, major components of the central nervous system, have the potential to interact with a wide range of growth factors and neurotrophic factors that influence neuronal migration, axon guidance pathways, and neurite outgrowth. Recent studies have also revealed the role of CS/DS chains in the orchestration of the neural stem/progenitor cell micromilieu. Individual functional proteins recognize a set of multiple overlapping oligosaccharide sequences decorated to give different sulfation patterns, which are termed here "wobble CS/DS oligosaccharide motifs," and induce signaling pathways essential for the proliferation, self-renewal, and cell lineage commitment of neural stem/progenitor cells.
软骨素硫酸盐/硫酸皮肤素(CS/DS)蛋白聚糖是中枢神经系统的主要成分,它们有可能与多种生长因子和神经营养因子相互作用,这些因子影响神经元迁移、轴突导向途径和神经突生长。最近的研究还揭示了 CS/DS 链在神经干细胞/祖细胞微环境协调中的作用。单个功能蛋白识别一组多个重叠的寡糖序列,这些序列被修饰以产生不同的硫酸化模式,这里称为“摆动 CS/DS 寡糖基序”,并诱导对神经干细胞/祖细胞的增殖、自我更新和细胞谱系决定至关重要的信号通路。
