细胞外基质中的蛋白聚糖在轴突生长和导航、可塑性和损伤神经元的再生中起着重要作用。不同种类的蛋白聚糖可以支持或抑制细胞生长,它们的功能部分由高度特异性的结构特征决定。其中,糖胺聚糖糖链上的硫酸化模式是一组多样化和灵活的结果的最重要决定因素。最近的蛋白多糖硫酸化研究说明了将生物学作用归因于特定硫酸化模式的挑战,并提出了高度相似的分子可能对神经元产生相反影响的方式。蛋白聚糖的受体,尚未得到充分的表征,显示出类似的微妙的影响谱。不同种类的蛋白聚糖通过重叠的受体家族和信号传导途径发挥作用。这使得它们能够以显着的特异性控制轴突生长和指导,但它对确定不同蛋白聚糖及其分类硫酸化表位的精确结合相互作用和下游效应提出了挑战。本文综述了蛋白聚糖硫酸化和受体相互作用在确定这些复杂分子如何影响神经元发育,生长和功能中的作用的现有和新出现的证据。
Proteoglycans in the extracellular matrix play vital roles in axon growth and navigation, plasticity, and regeneration of injured neurons. Different classes of proteoglycans may support or inhibit cell growth, and their functions are determined in part by highly specific structural features. Amongst these, the pattern of sulfation on the glycosaminoglycan sugar chains is a paramount determinant of a diverse and flexible set of outcomes. Recent studies of proteoglycan sulfation illustrate the challenges of attributing biological actions to specific sulfation patterns, and suggest ways in which highly similar molecules may exert opposing effects on neurons. The receptors for proteoglycans, which have yet to be fully characterized, display a similarly nuanced spectrum of effects. Different classes of proteoglycans function via overlapping families of receptors and signaling pathways. This enables them to control axon growth and guidance with remarkable specificity, but it poses challenges for determining the precise binding interactions and downstream effects of different proteoglycans and their assorted sulfated epitopes. This review examines existing and emerging evidence for the roles of proteoglycan sulfation and receptor interactions in determining how these complex molecules influence neuronal development, growth, and function.
