编辑丨王多鱼 排版丨水成文 撰文丨王聪 阿尔茨海默病 （AD） 是最常见的神经退行性疾病，目前尚无有效的治疗方法。细胞外淀粉样斑块、神经原纤维缠结、 神经炎症以及神经元丢失是阿尔茨海默病神经病理学的特征。 β- 淀粉样蛋白 （Aβ） 是淀粉样斑块的主要成分，它是通过 β-分泌酶 BACE1 和 γ-分泌酶对 淀粉样前体蛋白 （APP） 进行连续切割而产生的。 APP、BACE1 和 γ-分泌酶的失调会增加 Aβ 的生成，而小胶质细胞的功能障碍会 降低对 Aβ 的清除，从而导致 Aβ 的沉积。Aβ 沉积的增加反过来会激活小胶质细胞，促进大量促炎细胞因子的分泌。 肠道微生物群及其代谢物的失调在阿尔茨海默病 （AD） 的发病机制中发挥着关键作用。 丁酸 （Butyrate） 是一种短 链脂肪酸 （SCFA） ，主要由肠道细菌通过膳食纤维的发酵产生，具有多种生理功能，包括调节肠道健康、抗炎和神经 保护作用。近年来，研究发现丁酸在大脑健康及神经退行性疾病 （例如阿尔茨海默病） 中可能发挥有益作用。 提高丁 酸的生物利用度，对于其临床应用至关重要。 2025 年 11 月 17 日，温州医科大学/瓯江实验室 吴伊丽 教授 ...

Core Insights - The research published in "Nature Aging" reveals the critical role of the "lipid metabolism-microglial activation-neuroinflammation" axis in Alzheimer's disease, identifying MFE-2 as a novel therapeutic target for drug development [1][6] - CKBA, a small molecule candidate derived from traditional Chinese medicine, shows potential in treating Alzheimer's disease by effectively crossing the blood-brain barrier and exhibiting multiple therapeutic effects in animal models [1][2][6] Company Developments - The company is actively advancing the clinical development of CKBA for vitiligo (Phase III) and rosacea (Phase II/III), while accelerating the innovation drug development for Alzheimer's disease [2] - CKBA has demonstrated significant effects in improving cognitive function, reducing neuroinflammation, decreasing Aβ plaque burden, and alleviating anxiety behaviors in Alzheimer's disease model mice [1][6] Industry Context - Alzheimer's disease is the most common neurodegenerative disease globally, accounting for over half of dementia cases, characterized by progressive cognitive decline and persistent neuroinflammation [5] - The study addresses a critical scientific question regarding the mechanisms of lipid metabolism disruption and its role in immune activation in the brain, which has been underexplored [5][6]

Core Viewpoint - Alzheimer's disease (AD) is characterized by the gradual decline of memory and cognitive functions, with a focus on the complex interactions of various disorders leading to neurodegeneration rather than solely targeting specific neuronal features [2] Group 1: Research Findings - A recent study published in Nature Biomedical Engineering developed aptamer-armed monocytes (Apt-M) that can target and clear extracellular Tau protein, alleviating neuroinflammation in Alzheimer's disease mouse models and improving memory and spatial learning abilities without causing toxicity [3][8] - Monocytes, particularly the Ly6C+ inflammatory subset, can migrate across the blood-brain barrier (BBB) and differentiate into macrophages, which can phagocytize neurotoxic substances like Aβ, potentially slowing the progression of neurodegeneration [6] - The study highlights that the engineered Apt-M can effectively penetrate the BBB and accumulate in Tau-rich brain regions, significantly reducing Tau protein burden and suppressing neuroinflammation, thereby maintaining neuronal and mitochondrial integrity [8][10] Group 2: Mechanism and Implications - The research indicates that enhancing the beneficial functions of monocytes is ideal for treating Alzheimer's disease, as they can be modified to improve their efficacy in clearing toxic proteins [6][7] - The use of nucleic acid aptamers, which are short single-stranded DNA or RNA oligonucleotides, allows for targeted delivery and effective clearance of Tau proteins, presenting a promising strategy for Alzheimer's disease intervention [7][10] - Overall, the study suggests that nucleic acid aptamer-guided monocytes provide a novel approach for targeted delivery, effective clearance, and sustained neuroprotection in Alzheimer's disease treatment [10]

Core Viewpoint - Novo Nordisk's GLP-1 drug, semaglutide, is being tested for its efficacy in treating Alzheimer's disease, with results expected this fall. A successful trial could revolutionize Alzheimer's treatment and potentially add $15 billion in annual sales for the company [1][2]. Group 1: Drug Development and Market Context - Semaglutide has expanded its application from obesity and diabetes to heart and liver diseases, and now Alzheimer's [1]. - The research was prompted by a finding that diabetes patients using GLP-1 drugs had a 20% lower risk of developing dementia compared to other treatments [1]. - UBS analysts estimate a 10% chance of success for Novo Nordisk in the Alzheimer's treatment space, but the potential revenue impact is significant if successful [1][2]. Group 2: Competitive Landscape and Financial Performance - Novo Nordisk has faced growth challenges, leading to two downward revisions of growth forecasts this year due to competition from cheaper alternatives and Eli Lilly's stronger GLP-1 products [2]. - The company's stock price has dropped over 58% in the past 12 months, significantly more than Eli Lilly's 23% decline [2][4]. Group 3: Mechanism of Action and Research Challenges - Semaglutide operates differently from existing Alzheimer's drugs, which primarily target amyloid-beta proteins. It mimics the GLP-1 hormone, potentially reducing inflammation and altering brain glucose metabolism [6]. - The design of the clinical trial poses challenges, as Alzheimer's is known for high failure rates in drug development. The trial will focus on mild patients with detected amyloid proteins [8]. - Even minor positive results could lead to semaglutide being used as a preventive measure for Alzheimer's [8].
