微载体或纳米载体的设计主要集中在疏水性、生物降解性、大小、形状、表面电荷和毒性等性质上,以便它们能够在载药量、释放动力学、生物分布、细胞摄取和生物相容性方面实现最佳的递送。将对刺激敏感的部分整合到载体中,将导致“智能”输送系统。进一步的发展将是赋予载体治疗功能,使其不再仅仅作为被动实体在靶组织释放药物,而是本身可以被视为治疗剂。在这篇综述中,我们将讨论最近和过去十年来正在进行的设计具有生物益处的治疗性药物载体的努力,包括清除或产生ROS,促炎或抗炎,以及免疫逃避特性,以提高递送系统的整体治疗效果。
Design of micro- or nanocarriers for drug delivery has primarily been focused on properties such as hydrophobicity, biodegradability, size, shape, surface charge, and toxicity, so that they can achieve optimal delivery with respect to drug loading, release kinetics, biodistribution, cellular uptake, and biocompatibility. Incorporation of stimulus-sensitive moieties into the carriers would lead to “smart” delivery systems. A further evolution would be to endow the carrier with a therapeutic function such that it no longer serves as a mere passive entity to release the drug at the target tissue but can be viewed as a therapeutic agent in itself. In this review, we will discuss recent and ongoing efforts over the past decade to design therapeutic drug carriers that confer a biological benefit, including ROS scavenging or generating, pro- or anti-inflammatory, and immuno-evasive properties, to enhance the overall therapeutic efficacy of the delivery systems.
