Core Viewpoint - The research reveals a surprising link between peripheral cancers and a reduced risk of Alzheimer's disease, suggesting that certain cancer patients may possess a protective mechanism against Alzheimer's through the protein cystatin-c [2][6]. Group 1: Research Findings - The study published in Cell demonstrates that tumor cells secrete cystatin-c, which acts as a "molecular glue" to activate TREM2 receptors on microglial cells, facilitating the clearance of amyloid plaques associated with Alzheimer's disease [3][5]. - In experiments with Alzheimer's model mice implanted with peripheral cancer cells, a significant reduction in amyloid plaques and improved cognitive function were observed [6][12]. Group 2: Mechanism of Action - Cystatin-c binds to toxic amyloid oligomers in the brain, activates microglial cells via TREM2, and enhances the clearance of existing amyloid plaques [9][15]. - The protective effect of cystatin-c was confirmed through gene knockout experiments, where the absence of cystatin-c eliminated the protective benefits, which were restored upon reintroduction of normal cystatin-c [13][14]. Group 3: Therapeutic Implications - This research opens new avenues for Alzheimer's treatment by focusing on the removal of existing amyloid plaques rather than solely preventing their formation [17][21]. - Direct injection of recombinant cystatin-c into Alzheimer's model mice successfully reduced amyloid burden and improved learning and memory capabilities [18][20].

作为我国高发的恶性肿瘤之一，胃癌的发病率和死亡率长期位居癌症榜单前列。更令人揪心的是，超过 六成患者确诊时已处于晚期，其中约12%-13%为HER2 阳性分型。这种分型的胃癌侵袭性更强、更易复 发转移，患者在一线治疗失败后，二线治疗可选方案极少，中位生存期不足10个月，生存质量深受影 响。 日前，国家药品监督管理局正式批准一款靶向抗体偶联药物（ADC）——注射用德曲妥珠单抗的新适 应证，用于治疗既往接受过含曲妥珠单抗治疗方案的局部晚期或转移性HER2阳性成人胃或胃食管结合 部腺癌患者。这一突破填补了我国二线HER2阳性胃癌靶向治疗的空白，为众多陷入治疗困境的患者带 来延长生存的新希望。 国际多中心III期临床试验DESTINY-Gastric04数据显示，与传统治疗方案相比，该药物使患者死亡风险 降低30%，中位生存期延长至14.7个月，较传统方案提升近3个月；两年生存率实现翻倍，客观缓解率 达44.3%，其中7例患者达到完全缓解，疾病控制率更是高达91.9%。更重要的是，其安全性特征可接受 且总体可管理，未发现新的安全性问题。该研究结果已在2025 年美国临床肿瘤学会年会上以重磅口头 报告形式发布，并同步发 ...
