The therapeutic effect of nanoparticles is limited in solid tumors, especially desmoplastic tumors, because the tumor matrix hinders the delivery of nanoparticles. As the most abundant cells in the tumor stroma, tumor-associated fibroblasts (TAFs) produce a dense extracellular matrix, which leads to higher tissue fluid pressure, thereby creating a physical barrier for nanoparticle delivery. Therefore, researchers focused on eliminating TAFs to combat desmoplastic tumors. In recent years, a series of methods for TAFs have been developed. In this paper, we first introduced the biological mechanism of TAFs hindering the penetration of nanoparticles. Then, the different methods of eliminating TAFs were summarized, and the mechanism of nanomedicine in eliminating TAFs was highlighted. Finally, the problems and future development directions for TAFs treatment were discussed from the perspective of the treatment of desmoplastic tumors.
纳米颗粒的治疗效果在实体瘤中受到限制,尤其是促结缔组织增生性肿瘤,因为肿瘤基质阻碍了纳米颗粒的传递。肿瘤相关成纤维细胞(TAFs)作为肿瘤基质中最丰富的细胞,产生致密的细胞外基质,导致组织液压力升高,从而为纳米颗粒的传递形成物理屏障。因此,研究人员专注于消除 TAFs 以对抗促结缔组织增生性肿瘤。近年来,已经开发出一系列针对 TAFs 的方法。在本文中,我们首先介绍了 TAFs 阻碍纳米颗粒渗透的生物学机制。然后,总结了消除 TAFs 的不同方法,并强调了纳米医学在消除 TAFs 中的作用机制。最后,从促结缔组织增生性肿瘤治疗的角度出发,讨论了 TAFs 治疗中存在的问题和未来的发展方向。
