Multiple Myeloma (MM) remains an incurable disease due to high relapse rates and fast development of drug resistances. The introduction of monoclonal antibodies (mAb) has caused a paradigm shift in MM treatment, paving the way for targeted approaches with increased efficacy and reduced toxicities. Nevertheless, antibody-based therapies face several difficulties such as high immunogenicity, high production costs and limited conjugation capacity, which we believe could be overcome by the introduction of nucleic acid aptamers. Similar to antibodies, aptamers can bind to their targets with great affinity and specificity. However, their chemical nature reduces their immunogenicity and production costs, while it enables their conjugation to a wide variety of cargoes for their use as delivery agents. In this review, we summarize several aptamers that have been tested against MM specific targets with promising results, establishing the rationale for the further development of aptamer-based strategies against MM. In this direction, we believe that the study of novel plasma cell surface markers, the development of intracellular aptamers and further research on aptamers as building blocks for complex nanomedicines will lead to the generation of next-generation targeted approaches that will undoubtedly contribute to improve the management and life quality of MM patients.
由于复发率高和耐药性快速发展,多发性骨髓瘤(MM)仍然是一种无法治愈的疾病。单克隆抗体(mAb)的引入使MM治疗发生了范式转变,为提高疗效和降低毒性的靶向治疗方法铺平了道路。然而,基于抗体的疗法面临着一些困难,如高免疫原性、高生产成本和有限的偶联能力,我们认为引入核酸适配体可以克服这些困难。与抗体类似,适配体可以以高亲和力和特异性结合其靶标。然而,它们的化学性质降低了其免疫原性和生产成本,同时使其能够与多种货物偶联,用作递送剂。在这篇综述中,我们总结了几种针对MM特异性靶标进行测试且结果 promising 的适配体,为进一步开发基于适配体的MM治疗策略奠定了理论基础。在这个方向上,我们相信对新型浆细胞表面标志物的研究、细胞内适配体的开发以及对作为复杂纳米药物构建块的适配体的进一步研究,将导致下一代靶向治疗方法的产生,这无疑将有助于改善MM患者的治疗和生活质量。 (注:原文中“promising”未翻译完整,推测可能是“有前景的”之类意思,可根据实际情况完善)
