新一期《自然》杂志刊登了一项里程碑式研究：美国斯坦福大学医学院团队利用非基因匹配的健康前体 细胞，替换掉罹患桑德霍夫病小鼠超过半数的病变小胶质细胞，使实验鼠寿命从135天延长至250天，运 动功能与探索行为几乎恢复至正常水平。这也是首次为泰萨克斯病和桑德霍夫病等目前无药可治的致命 性脑病提供了"即用型"细胞疗法蓝图。 该成果同时解决了三大难题：无需全身毒性预处理、无需基因编辑即可补充缺失酶、避免排异反应。方 案所用放射剂量、微胶质清除剂及免疫抑制剂均已用于其他疾病，具备快速进入临床的潜力。同时，该 疗法不依赖患者自身细胞，未来有望像输血一样成为"货架产品"，大幅降低成本与等待时间。 团队指出，阿尔茨海默病、帕金森病等常见神经退行性疾病同样伴随小胶质功能障碍，这或许是溶酶体 病的"慢速版本"。如果后续人体试验成功，受益者远不止罕见病患儿，而是数百万神经退行性疾病患 者。下一步，团队计划在更接近人类的大型动物模型中验证这种疗法的安全性，并与美国食品和药物管 理局讨论设计早期临床试验。 （文章来源：科技日报） 泰萨克斯病和桑德霍夫病同属溶酶体贮积症。患儿因缺乏关键酶，神经"清道夫"小胶质细胞及邻近神经 元内代谢垃圾 ...

Core Viewpoint - Osteoarthritis (OA) is a degenerative joint disease primarily affecting the elderly, characterized by the degradation of articular cartilage and subsequent joint pain and limited mobility. Current treatments include non-steroidal anti-inflammatory drugs and, in severe cases, total joint replacement [2]. Group 1: Treatment Innovations - The FDA has recently approved Matrix-associated Autologous Chondrocyte Implantation (MACI) for repairing isolated cartilage injuries in patients aged 18-55, indicating that cell therapy may become an effective treatment for osteoarthritis [3]. - Procr chondroprogenitors, identified in a study published in Cell, are sensitive to mechanical stimuli and play a crucial role in maintaining and regenerating articular cartilage, presenting a promising cell source for treating degenerative orthopedic diseases like osteoarthritis [4][9]. Group 2: Research Findings - The study found that mechanical stimulation from forced running significantly increased the number of Procr+ cells, while mechanical unloading decreased their numbers. OA activates Procr+ cells to repair cartilage erosion, and their genetic knockout accelerates OA progression [6]. - Inhibition of the mechanosensor Piezo1 significantly impairs the cartilage repair function of Procr+ cells, while intra-articular injection of Piezo1 agonists improves OA symptoms [6]. - Purified Procr+ superficial cells, after expansion and in vivo transplantation, can effectively repair cartilage defects, highlighting their potential as a reliable cell source for treating knee joint diseases like osteoarthritis [9].

Core Viewpoint - Capricor Therapeutics Inc. received a Complete Response Letter (CRL) from the FDA regarding its Biologics License Application (BLA) for Deramiocel, indicating that the application cannot be approved in its current form due to insufficient evidence of effectiveness and the need for additional clinical data [1][2]. Group 1: FDA Response and Requirements - The FDA stated that the BLA does not meet the statutory requirement for substantial evidence of effectiveness and that additional clinical data is needed [2]. - The CRL referenced outstanding items in the Chemistry, Manufacturing and Controls (CMC) section, which Capricor claims to have addressed in prior communications, but the FDA did not review these materials due to the timing of the CRL issuance [3]. Group 2: Next Steps and Company Plans - The FDA confirmed that it will restart the review clock upon resubmission and offered Capricor the opportunity to request a Type A meeting to discuss the path forward [4]. - Capricor plans to submit data from the Phase 3 HOPE-3 clinical trial to provide additional evidence of effectiveness, with topline results expected in the third quarter of 2025 [5]. Group 3: Market Reaction - Following the news, CAPR stock is down 37.4% at $7.14 during the premarket session [6].

Core Viewpoint - The article discusses the development of CAR-M (Chimeric Antigen Receptor Macrophages) therapy targeting inflammation, highlighting its potential in treating various inflammatory diseases by converting immune responses into anti-inflammatory effects [7][10]. Group 1: Inflammation and Macrophages - Inflammation plays a critical role in many diseases, and unresolved inflammation can lead to severe outcomes such as organ failure [2]. - Macrophages are strategically located throughout the body and are essential for maintaining homeostasis by clearing pathogens and harmful substances [2]. - M2 macrophages have shown promise in reducing damage in various disease models, but their effectiveness is limited by their phenotypic plasticity, which can lead to pathogenic transformation in inflammatory environments [2][8]. Group 2: CAR-M Therapy Development - Recent research from the University of Sydney introduced CAR-M therapy, which uniquely transforms immune responses into immunosuppressive responses when triggered by inflammatory cytokines [7]. - The CAR-M design includes an extracellular domain that binds to tumor necrosis factor (TNF) and an intracellular domain that activates anti-inflammatory responses, programming macrophages to exhibit M2-like functions [7][10]. Group 3: Efficacy in Animal Models - CAR-M therapy demonstrated efficacy in both acute and chronic inflammatory disease models in mice, showing a transition to an anti-inflammatory phenotype in inflamed kidneys and improving kidney function and structure [8][10]. - In models of kidney ischemia-reperfusion injury, CAR-M cells effectively reduced tissue damage and maintained their anti-inflammatory phenotype in the presence of high TNF levels [8][10].
