173. 细胞能记忆什么?

from 知为谁 · host 知为谁

这段引文来自一篇发表在 Quanta Magazine 上的文章,该杂志由西蒙斯基金会提供支持。这篇文章探讨了 细胞记忆 的开创性新研究,挑战了长期以来认为记忆仅限于多细胞神经系统的观点。文章追溯了芭芭拉·麦克林托克(Barbara McClintock)等早期科学家的历史性工作,他们观察到细胞在面对压力时表现出看似“有思想”的反应。它接着详细介绍了尼古拉·库库什金(Nikolay Kukushkin)的实验,该实验表明人类肾脏细胞可以“记住”化学信号模式,这与所有动物中普遍存在的 间隔效应 相符。文章还讨论了何伯特·斯宾塞·詹宁斯(Herbert Spencer Jennings)和比阿特丽斯·吉尔伯(Beatrice Gelber)被忽视的工作,他们的研究在当时因与主流观念相悖而被驳回,但现在正在为 单细胞学习 领域提供信息。总的来说,该文本揭示了对记忆的重新定义,将其视为一种更普遍的生物现象,而不仅仅局限于大脑功能。内容来源:https://www.quantamagazine.org/what-can-a-cell-remember-20250730/
