Described herein are liposome-based nanocarriers that selectively target bone marrow, minimize tumor delivery, and maintain high drug concentrations in bone marrow when compared to conventional systemic delivery. The composition of the liposome-based nanocarriers may also be tuned to selectively target lymph nodes and other reticuloendothelial system organs (e.g., spleen, e.g., liver). Also described herein are methods of imaging and mapping the bone marrow and/or other reticuloendothelial system organs using the described liposome-based nanocarriers. These methods provide high resolution non-invasive and quantitative imaging via PET, which offers advantages over conventional imaging/tracking methods. Furthermore, in certain embodiments, the liposome-based carriers are used to stabilize and deliver radioprotectant/free radical scavenger drugs to the bone marrow, thereby protecting the bone marrow from subsequent radiation exposure, thereby limiting the adverse impact of radiation exposure on the individual.
本文描述了基于脂质体的纳米载体,能够选择性靶向骨髓,最小化肿瘤传递,并与传统的全身传递相比,在骨髓中保持高浓度的药物。基于脂质体的纳米载体的组成也可以调整为选择性靶向淋巴结和其他网状内皮系统器官(例如脾脏、肝脏)。本文还描述了使用所述基于脂质体的纳米载体进行骨髓和/或其他网状内皮系统器官的成像和映射的方法。这些方法通过PET提供高分辨率的非侵入性和定量成像,相对于传统的成像/追踪方法具有优势。此外,在某些实施例中,基于脂质体的载体被用于稳定和传递放射防护剂/自由基清除剂药物至骨髓,从而保护骨髓免受随后的辐射暴露,从而限制辐射暴露对个体的不良影响。
