摘要
癌症治疗的最新进展凸显了传统单一疗法在治疗复杂恶性肿瘤方面的不足。因此,人们越来越关注能够克服单一疗法局限性的协同疗法,从而开发出更个性化、更有效的方法。其中,光热疗法(PTT)与化疗的结合已成为一种很有前景的肿瘤治疗方法。在这项研究中,我们提出了一种利用热致伸缩性介孔二氧化硅纳米粒子(MSN)作为化疗药物多柔比星递送系统的新方法。通过在 MSN 中加入光热剂硫化铜(CuS)纳米颗粒,得到的复合材料表现出了强大的光热特性。此外,在二氧化硅外层还加入了上临界溶液温度(UCST)聚合物作为 "守门员",从而实现了对药物释放动力学的精确控制。这种创新型纳米材料有效地将热致伸缩行为与 PTT 相结合,从而最大限度地减少了传统化疗对健康组织造成的附带损害。此外,在利用小鼠乳腺癌细胞(4 T1)进行的体外研究和利用 4 T1 肿瘤小鼠模型进行的体内实验中,我们的纳米材料都显示出协同效应,提高了 PTT 和化疗联合应用的抗肿瘤疗效。UCST 响应式纳米平台具有卓越的光热转换效率、稳定性和生物相容性,在临床应用方面具有巨大的潜力。
NIR-triggered and Thermoresponsive Core-shell nanoparticles for synergistic anticancer therapy
Recent advancements in cancer treatment have underscored the inadequacy of conventional monotherapies in addressing complex malignant tumors. Consequently, there is a growing interest in synergistic therapies capable of overcoming the limitations of monotherapies, leading to more personalized and effective approaches. Among these, the combination of photothermal therapy (PTT) and chemotherapy has emerged as a promising avenue for tumor management. In this study, we present a novel approach utilizing thermoresponsive mesoporous silica nanoparticles (MSN) as a delivery system for the chemotherapeutic drug doxorubicin. By incorporating photothermal agent copper sulfide (CuS) nanoparticles into the MSN, the resulting composite material exhibits potent photothermal properties. Furthermore, the integration of an upper critical solution temperature (UCST) polymer within the silica outer layer serves as a “gatekeeper”, enabling precise control over drug release kinetics. This innovative nanomaterial effectively merges thermoresponsive behavior with PTT, thereby minimizing the collateral damage associated with traditional chemotherapy on healthy tissues. Moreover, in both in vitro studies using mouse breast carcinoma cells (4 T1) and in vivo experiments utilizing a 4 T1 tumor-bearing mouse model, our nanomaterials demonstrated synergistic effects, enhancing the anti-tumor efficacy of combined PTT and chemotherapy. With its remarkable photothermal conversion efficiency, robust stability, and biocompatibility, the UCST-responsive nanoplatform holds immense potential for clinical applications.
