神经元缠结是阿尔茨海默病的神经病理学标志之一,具有动态的成熟寿命,其与进行性神经元功能障碍和认知缺陷相关。随着神经元缠结成熟,神经元的生物学经历了广泛的变化,这可能影响生物标志物识别和治疗靶向。神经元缠结成熟度包括三个层次:前缠结、成熟缠结和幽灵缠结。在这篇综述中,我们详细介绍了在人脑中观察到的不同和重叠的特征,关于神经元的形态变化,从细胞内到细胞外空间的转换,tau蛋白免疫染色模式,以及tau蛋白亚型在神经元缠结的整个生命周期中的表达变化。tau蛋白的翻译后修饰,如磷酸化,泛素化,构象事件和截短进行了讨论,使tau蛋白免疫染色模式的背景化。我们总结了积累和新兴的知识神经缠结成熟,讨论了目前的工具,用于解释死后大脑的动态性质,并考虑认知功能障碍和tau蛋白生物标志物的影响。
Neurofibrillary tangles, one of the neuropathologic hallmarks of Alzheimer's disease, have a dynamic lifespan of maturity that associates with progressive neuronal dysfunction and cognitive deficits. As neurofibrillary tangles mature, the biology of the neuron undergoes extensive changes that may impact biomarker recognition and therapeutic targeting. Neurofibrillary tangle maturity encompasses three levels: pretangles, mature tangles, and ghost tangles. In this review, we detail distinct and overlapping characteristics observed in the human brain regarding morphologic changes the neuron undergoes, conversion from intracellular to extracellular space, tau immunostaining patterns, and tau isoform expression changes across the lifespan of the neurofibrillary tangle. Post‐translational modifications of tau such as phosphorylation, ubiquitination, conformational events, and truncations are discussed to contextualize tau immunostaining patterns. We summarize accumulated and emerging knowledge of neurofibrillary tangle maturity, discuss the current tools used to interpret the dynamic nature in the postmortem brain, and consider implications for cognitive dysfunction and tau biomarkers.
