近期，价格百万的"抗癌针"屡屡登上热搜，有网友称，注射"抗癌针"后癌细胞被完全清除了。不少人惊呼，癌症真的要被攻克了吗？所谓 的"抗癌针"到底是怎么回事？真能清除癌细胞吗？ 北京大学人民医院血液科副主任医师 吕萌：CAR-T细胞之所以目前来说比较稀有，因为它是一个个性化定制的过程，每一个患者所接受的这 份CAR-T都是用自己的细胞培养了全世界独一无二的药品。 "CAR-T疗法"目前在国内研发的上市产品价格从几十万元到一百多万元价格不等，如此昂贵的原因除了高度定制化、生产工艺复杂外，还包括 漫长的研发成本以及更加严格的监管与供应链等。 "扩增"：在体外大量扩增这些"超级杀手"CAR-T细胞。 "回输"：将它们像输血一样回输到患者体内。 CAR-T并非万能 仅对部分血液肿瘤有效 中国工程院院士 中国抗癌协会理事长 樊代明：正常人都有癌细胞，但是为什么不得癌？因为身体有强大的自然力，包括免疫力。免疫力从哪 里来？主要是从淋巴细胞来。肿瘤病人肿瘤长起来以后，淋巴细胞杀不了或者是有各种原因，要不就是不认识，要不就是力量不够。在这种情 况下，如果对淋巴细胞进行改装，让它能够认识癌细胞，而且能够杀死癌细胞，这个就是免疫细胞 ...

Core Viewpoint - The article discusses a novel approach to enhance CD47 blockade therapy for cancer treatment by utilizing biomineralized nanoparticles that facilitate phagocytosis and mitochondrial DNA sensing, leading to improved therapeutic outcomes [2][5]. Group 1: Research Background - Antigen-presenting cells (APCs) mediate the phagocytosis of cancer cells and initiate antigen presentation through sensing mitochondrial DNA (mtDNA), which is a critical mechanism in CD47 blockade therapy [2]. - Current strategies targeting CD47 often lack regulation of mtDNA sensing, limiting their effectiveness [2]. Group 2: Research Findings - The study developed biomineralized nanoparticles ZnCO₃@BSA/siCD47 that enhance CD47 blockade therapy by promoting APC phagocytosis and mtDNA sensing, resulting in significant tumor growth inhibition [2][5]. - The nanoparticles are designed to balance the stable encapsulation of siRNA with efficient intracellular release, achieving effective CD47 silencing and Zn²⁺ overload [5][6]. - In colorectal cancer and melanoma models, ZnCO₃@BSA/siCD47 restored APC function, increased T cell infiltration, and achieved a tumor growth inhibition rate of 93% [5][6]. Group 3: Mechanism of Action - The strategy involves Zn²⁺ overload to enhance phagocytosis and STING activation, while the pH-responsive ZnCO₃@BSA matrix ensures synchronized delivery of Zn²⁺ and siRNA [6]. - The treatment induces CD47 knockdown, calreticulin exposure, and mtDNA release, which are crucial for effective immune response [6].

Core Viewpoint - The article discusses the potential of SARS-CoV-2 mRNA vaccines as broad-spectrum immune activators that can sensitize tumors to immune checkpoint inhibitors (ICIs), significantly improving survival rates in advanced cancer patients [4][10]. Group 1: Impact of mRNA Vaccines on Cancer Treatment - Recent studies indicate that systemic administration of high-immunogenic mRNA nanoparticles can reset the immune microenvironment, making resistant tumors sensitive to ICIs [2]. - The research from MD Anderson Cancer Center shows that advanced cancer patients who received the SARS-CoV-2 mRNA vaccine within 100 days before starting ICI treatment had significantly extended overall survival [8]. - Specifically, the median survival for non-small cell lung cancer patients increased from 20.6 months to 37.3 months, and for metastatic melanoma patients, it rose from 26.7 months to over 36 months [8]. Group 2: Mechanism of Action - The study found that the SARS-CoV-2 mRNA vaccine significantly increased type I interferon (IFN-I) levels and activated antigen-presenting cells, which in turn stimulated CD8+ T cells to combat tumors [10][12]. - The vaccine also enhanced PD-L1 protein expression in tumors and promoted T lymphocyte activation within the tumor microenvironment [10]. Group 3: Clinical Implications - The findings suggest that clinically available mRNA vaccines targeting non-tumor-associated antigens can serve as powerful immune modulators, making tumors sensitive to ICIs [12]. - The combination of SARS-CoV-2 mRNA vaccines with ICIs can maintain T cell responses, thereby inhibiting tumor growth and improving cancer patient survival rates [12].
