Karl Deisseroth、Peter Hegemann和Georg Nagel因开发光遗传学技术获得2026年诺贝尔生理学或医学奖1。这项突破性研究通过将光敏蛋白质导入神经细胞，使科学家能够用光控制脑细胞的开启和关闭1。
该技术的应用潜力已在多个领域得到验证。2012年MIT的一项实验中，研究人员用光遗传学激活了小鼠脑部记忆中枢的神经细胞，使未曾受过电击的小鼠在不同笼子里重现了恐惧反应1。光遗传学已进入视网膜变性患者的早期临床试验阶段，研究人员同时在探索该技术对帕金森症和癫痫等神经疾病的治疗潜力1。
Karl Deisseroth, Peter Hegemann, and Georg Nagel have been awarded the 2026 Nobel Prize in Physiology or Medicine for their development of optogenetics, a groundbreaking technology that enables scientists to control brain cells using light1. The technique works by introducing light-sensitive proteins into neural cells, allowing researchers to turn specific neurons on and off with precision1.
The practical applications of this discovery have already demonstrated remarkable promise. A 2012 MIT experiment showed that optogenetics could activate memory centers in mouse brains, causing mice that had not been exposed to electric shocks to exhibit fear responses in different cages—recreating memories through light stimulation alone1. Beyond experimental validation, the technology has advanced into early clinical trials for patients with retinal degeneration1. Researchers are also exploring the therapeutic potential of optogenetics for treating Parkinson's disease and epilepsy1.
