对话诺贝尔奖得主Katalin:在人迹未至的道路,我始终相信自己在做很重要的事情
3 6 Ke· 2026-01-05 10:50
改变世界的,往往不是最受追捧的潮流,而是那些在无人看见的漫长岁月里,依然选择忠于好奇、专注 于事的执着信念。在喧嚣的时代,卡塔林·考里科的存在本身,就是一份关于如何面对困境、坚守信念 的沉静宣言。 当整个世界将目光聚焦于mRNA疫苗,并将其誉为抗击新冠疫情的救星时,那位在幕后为其奠定科学基 石的女性,早已在一条人迹罕至、备受质疑的道路上孤独行走了四十年。 卡塔林·考里科(Katalin Karikó),这位2023年诺贝尔生理学或医学奖得主,她的故事并非一个典型 的、直线上升的天才叙事。它始于匈牙利一个没有自来水和稳定电力的小村庄。但"真正塑造我的,是 那种与自然紧密相连的简单家庭生活,"考里科在Edu指南专访中回顾道。观察小鸡破壳而出的童年好 奇心,成了她科学直觉的最初萌芽。 她的科研生涯,是一段与主流科学界固执己见的漫长角力。当分子生物学界痴迷于研究DNA和质粒 时,考里科却专注于当时被视为"棘手"且"无望"的信使RNA(mRNA)。在20世纪90年代加入宾夕法尼 亚大学后,她的道路并未变得平坦,反而遭遇了降职、难以获得资助以及同行普遍看衰的困境。"我一 直觉得自己正在做的事情很重要。只是其他人不理解," ...

Core Viewpoint - The article discusses a breakthrough in reversing immune aging through mRNA technology, which allows the liver to temporarily act as a "protein factory" to produce three key immune nutritional factors, enhancing immune responses in aged mice [1][2]. Group 1: Immune Aging and Its Challenges - Aging leads to significant changes in the immune system, including thymic shrinkage and reduced T cell production, resulting in decreased immune diversity and response to pathogens and cancer [4]. - Traditional methods to reverse immune aging, such as hormone therapy and cytokine injections, have shown limited effectiveness and often come with side effects [5][6]. Group 2: Innovative Approach - The research team utilized multi-omics analysis to identify weakened immune signaling pathways in aged mice, specifically the Notch, FLT3L, and IL-7 pathways, which are crucial for T cell development and function [8]. - A liver DFI reconstruction strategy was designed, encapsulating mRNA coding for DLL1, FLT3L, and IL-7 in lipid nanoparticles (LNP) for intravenous injection targeting the liver, which retains good function even in old age [8]. Group 3: Remarkable Outcomes - Post-treatment, aged mice exhibited significant thymic regeneration, increased new T cell numbers, and improved T cell receptor diversity, indicating a rejuvenation of the immune system [11]. - The treated aged mice showed a twofold increase in antigen-specific T cell numbers and response intensity to vaccines, nearing levels seen in younger mice [12]. - In tumor models, 40% of treated aged mice completely cleared tumors, while all control mice died due to tumor progression, indicating enhanced anti-tumor capabilities [14]. Group 4: Safety and Reversibility - The therapy is characterized by its safety, as effects diminish after treatment cessation, avoiding long-term uncontrolled risks. In models prone to spontaneous diabetes, the treatment did not accelerate disease progression, indicating it does not disrupt immune tolerance [18]. - Compared to traditional recombinant cytokine therapies, the mRNA approach resulted in significantly reduced systemic inflammatory responses and maintained normal liver and kidney function indicators, showcasing better safety profiles [19]. Group 5: Future Prospects - This research highlights the potential of using the liver for therapeutic protein production, which could serve as a universal strategy against age-related diseases, including cancer [21]. - The method's adjustability and reversibility allow for precise control over treatment duration, and it may be applicable to other key factors diminished by aging, offering new insights for various age-related diseases [21][22]. - The study opens new paradigms for systemic treatment through organ-specific delivery, providing innovative solutions to combat immune aging [23].
