神经胶质瘤是中枢神经系统最常见的原发性脑肿瘤。它的高侵袭性和深部脑损伤使其成为一个巨大的挑战,以开发一种非侵入性,精确和有效的治疗方法。在这里,我们报告了一种多功能治疗诊断剂,可以将成像和治疗集成到一个单一的纳米平台中,用于成像引导声动力学治疗(SDT)。SDT试剂通过将与锰离子螯合的中卟啉钠(DVDMS)包封到纳米脂质体(DVDMS-Mn-LP)中来制备。DVDSM-Mn-LP具有生理稳定性和生物相容性,并且它们可以在超声照射时产生单线态氧以杀死癌细胞。细胞和动物研究均表明,即使在存在颅骨的情况下,DVDMS ‐ Mn ‐ LP的SDT也可以显著提高抗肿瘤生长效率。此外,DVDSM-Mn-LP适用于MR和荧光成像。因此,本文报道的DVDMS ‐ Mn ‐ LP可能为胶质瘤治疗的成像引导方式提供有希望的策略。
Glioma is the most frequent primary brain tumour of the central nervous system. Its high aggressiveness and deep‐seated brain lesion make it a great challenge to develop a non‐invasive, precise and effective treatment approach. Here, we report a multifunctional theranostic agent that can integrate imaging and therapy into a single nano‐platform for imaging‐guided sonodynamic therapy (SDT). The SDT agents were fabricated by encapsulation of sinoporphyrin sodium (DVDMS) chelating with manganese ions into nanoliposomes (DVDMS‐Mn‐LPs). DVDMS‐Mn‐LPs are physiologically stable and biologically compatible, and they can produce singlet oxygen upon ultrasound irradiation to kill cancer cells. Both cell and animal studies demonstrated that SDT with DVDMS‐Mn‐LPs can significantly improve the antitumour growth efficiency even in the presence of skull. In addition, DVDMS‐Mn‐LPs are good for MR and fluorescence imaging. Thus, DVDMS‐Mn‐LPs reported here may provide a promising strategy for imaging‐guided modality for glioma treatment.
