突触组装和拆卸之间的适当平衡对于成年大脑中功能性神经元回路和突触可塑性的形成至关重要。在发育过程中,突触发生产生大量过量的突触,这些突触随后被消除。重要的是,发育过程中异常的突触解体是许多神经系统疾病的基础。Wnt分泌的蛋白质是一种强大的突触发生因子,在发育和成熟的大脑中调节突触组装和功能。最近的研究表明,用拮抗剂Dickkopf-1(Dkk 1)阻断Wnt可诱导成熟神经元中突触的快速解体。重要的是,Dkk 1介导由淀粉样蛋白-α诱导的突触丢失,淀粉样蛋白-α是阿尔茨海默病(AD)中的关键致病分子。这些发现为功能失调的Wnt信号传导对神经退行性疾病中观察到的突触丢失的潜在贡献提供了新的见解。在这篇综述中,我们讨论了Wnt信号在脊椎动物突触组装,功能和维护中的作用,并考虑Wnt信号功能障碍如何有助于神经退行性疾病,如AD的突触拆卸。
A proper balance between synapse assembly and disassembly is crucial for the formation of functional neuronal circuits and synaptic plasticity in the adult brain. During development, synaptogenesis generates a vast excess of synapses, which are subsequently eliminated. Importantly, aberrant synaptic disassembly during development underpins many neurological disorders. Wnt secreted proteins are robust synaptogenic factors that regulate synapse assembly and function in the developing and mature brain. Recent studies show that Wnt blockade with the antagonist Dickkopf-1 (Dkk1) induces the rapid disassembly of synapses in mature neurons. Importantly, Dkk1 mediates synaptic loss induced by Amyloid-ß, a key pathogenic molecule in Alzheimer’s disease (AD). These findings provide new insights into the potential contribution of dysfunctional Wnt signaling to synaptic loss observed in neurodegenerative diseases. In this review, we discuss the role of Wnt signaling in vertebrate synaptic assembly, function and maintenance, and consider how dysfunction of Wnt signaling could contribute to synaptic disassembly in neurodegenerative diseases such as AD.
