The separation of genetic material from bulk cytoplasm has enabled the evolution of increasingly complex organisms, allowing for the development of sophisticated forms of life. However, this complexity has created new categories of dysfunction, including those related to the movement of material between cellular compartments. In eukaryotic cells, nucleocytoplasmic trafficking is a fundamental biological process, and cumulative disruptions to nuclear integrity and nucleocytoplasmic transport are detrimental to cell survival. This is particularly true in post-mitotic neurons, where nuclear pore injury and errors to nucleocytoplasmic trafficking are strongly associated with neurodegenerative disease. In this review, we summarize the current understanding of nuclear pore biology in physiological and pathological contexts and discuss potential therapeutic approaches for addressing nuclear pore injury and dysfunctional nucleocytoplasmic transport.
遗传物质与大量细胞质的分离使越来越复杂的生物体得以进化,从而形成了复杂的生命形式。然而,这种复杂性创造了新的功能障碍类别,包括与细胞区室之间物质运动有关的功能障碍。在真核细胞中,核质转运是一种基本的生物学过程,核完整性和核质转运的累积破坏对细胞存活有害。在后有丝分裂神经元中尤其如此,核孔损伤和核质转运错误与神经退行性疾病密切相关。在这篇综述中,我们总结了生理和病理环境下核孔生物学的现有认识,并讨论了针对核孔损伤和功能失调的核质转运的潜在治疗方法。
