北京大学最新Cell子刊:激活肿瘤细胞焦亡,提高抗肿瘤免疫效果
生物世界· 2025-09-06 04:05
Core Viewpoint - Tumor immunotherapy, particularly immune checkpoint blockade (ICB) targeting the PD-1/PD-L1 pathway, shows significant promise in treating various advanced cancers, but low immune response rates hinder its efficacy and widespread application [2] Group 1: Research Findings - The study developed a self-luminous nanosystem that enhances the activation of pyroptosis in tumor cells, leading to a strong antitumor immune response when combined with anti-PD-L1 monoclonal antibodies [3][6] - Pyroptosis, a newly discovered form of immunogenic cell death (ICD), releases pro-inflammatory cytokines and damage-associated molecular patterns, triggering a robust antigen-specific immune response [5] - The self-luminous nanoparticles can emit light within the tumor without the need for an external light source, enhancing the generation of reactive oxygen species (ROS) and achieving significant tumor-killing effects [7] Group 2: Mechanism and Components - The nanosystem consists of amphiphilic porphyrin lipids, camptothecin derivatives, and a targeting moiety, which together facilitate the release of oxygen and hydrogen peroxide in the acidic tumor microenvironment [6] - The combination of chemotherapy and self-enhanced photodynamic therapy synergistically activates pyroptosis, driving immune activation that enhances the antitumor response to PD-L1 therapy [7]
癌症的“颠覆性疗法”,中国创新药的“DeepSeek时刻”!最核心的关键词:PD(L)1 bsAb
Hua Er Jie Jian Wen· 2025-08-31 11:58
在全球创新药领域,一个来自中国的突破正在引发巨大关注:PD(L)1双特异性抗体(bsAb)。这类新一代肿瘤免疫疗法,正被视为中国生物医药 产业的"DeepSeek时刻"——不仅因为其技术原理的颠覆性,更因为它可能改写全球癌症治疗的格局。 据追风交易台,汇丰最新研报指出,中国恒生生物科技指数今年迄今已上涨91%,远超大盘26%的涨幅。这一显著表现源于中国生物科技公司在 创新药物研发方面取得的重大突破,特别是在被称为"PD(L)1 bsAb"的先进肿瘤治疗领域。这类新型癌症免疫疗法采用双靶向策略,能同时与两 个不同靶点结合,增强免疫反应。 过去十年,默沙东的可瑞达(Keytruda)几乎定义了免疫肿瘤治疗的黄金标准。然而,中国药企康方生物研发的依维珂(AK112)在全球临床试 验中,已展现出超越Keytruda的疗效。今年世界肺癌大会上公布的临床数据更是直接点燃了市场热情,比喻为中国创新药的"DeepSeek时刻"。 根据汇丰的预测,全球PD(L)1市场将从2024年的530亿美元增长至2035年的1000亿美元,其中bsAb将占据约65%的份额,成为新的主流。这一过 程中,中国药企的先发优势将在市场竞争中发挥关 ...
