团队表示，除多通路协同抗癌，该平台还突破了当前细胞疗法在时间、工艺与成本方面的限制。现有疗 法需采集患者自身细胞，送往专门设施进行数周改造，再回输体内，而自然杀伤T细胞与人体免疫系统 天然兼容，不会引发严重排斥反应，因此可利用捐献的血液干细胞实现规模化生产。 为突破这些障碍，研究团队调用了自然杀伤T细胞。通过为其配备靶向胰腺癌细胞蛋白"间皮素"的嵌合 抗原受体，这些细胞能同时启动多种攻击机制，对肿瘤展开全方位围剿。 在针对胰腺原位肿瘤及肝转移瘤（最常见且致命的转移类型）的严苛动物模型中，CAR-NKT细胞展现 出强大的肿瘤清除能力。即便在高度炎性的肿瘤微环境中，治疗细胞仍保持抗癌活性，且不易出现衰 竭。 美国加州大学洛杉矶分校科研团队开发出一种新型嵌合抗原受体-自然杀伤T细胞（CAR-NKT）免疫疗 法。即便癌细胞已转移至其他器官，该疗法也能精准识别并摧毁胰腺癌细胞。相关论文发表于新一期 《美国国家科学院院刊》。 此前，嵌合抗原受体-T（CAR-T）细胞疗法虽在部分血癌治疗中取得突破，却难以应对胰腺癌等实体 瘤。胰腺肿瘤外围包裹着致密的结缔组织与抑制性免疫细胞，形成一道天然屏障，阻碍治疗细胞进入。 更棘手的是 ...

Core Viewpoint - The research reveals the unique biological phenomenon of "male pregnancy" in seahorses and their close relatives, uncovering the cellular and molecular mechanisms behind it [3]. Group 1: Mechanism of Male Pregnancy - Male seahorses possess a specialized brood pouch that allows them to carry fertilized eggs, providing protection, oxygen, nutrients, and immune support to the embryos, comparable to mammalian uteri [1]. - The study identified a type of epithelial progenitor cell with stem cell potential that is crucial for the formation of the brood pouch, regulated by male hormones [1][2]. - The brood pouch's inner layer thickens during early pregnancy, forming structures similar to mammalian placentas, and the presence of "trophoblast-like cells" indicates evolutionary adaptations [2]. Group 2: Immune Regulation - Seahorses lack the foxp3 gene, which is essential for immune tolerance in mammals, and have evolved a unique "non-foxp3 dependent" immune regulation mechanism to prevent the paternal immune system from rejecting the embryos [2]. - The study highlights the dynamic balance of immune responses at the maternal-fetal interface, which is critical for successful pregnancy [2]. Group 3: Evolutionary Insights - The research compares different types of brood pouches across seahorse species, suggesting that the evolutionary origin of these structures may stem from specialized epidermal cells that initially helped attach sticky eggs to the male's body [2]. - Over time, these cells evolved to recruit more functionally similar cells, leading to the complexity and diversity of brood pouch structures [2].
