Significant progress has been made in the field of cancer immunotherapy, where the goal is to activate or modulate the body's immune response against cancer. However, current immunotherapy approaches exhibit limitations of safety and efficacy due to systemic delivery. In this context, the use of nanotechnology for the delivery of cancer vaccines and immune adjuvants presents a number of advantages such as targeted delivery to immune cells, enhanced therapeutic effect, and reduced adverse outcomes. Recently, gold nanoparticles (AuNP) have been explored as immunotherapy carriers, creating new AuNP applications that merit a critical overview. This review highlights recent advances in the development of AuNP mediated immunotherapies that harness AuNP biodistribution, optical properties and their ability to deliver macromolecules such as peptides and oligonucleotides. It has been demonstrated that the use of AuNP carriers can improve the delivery and safety of immunotherapy agents, and that AuNP immunotherapies are well suited for synergistic combination therapy with existing cancer therapies like photothermal ablation.
Cancer immunotherapy approaches are rapidly evolving and are some of the most promising avenues to approach malignancies. This review summarizes the role of gold nanoparticles in immunotherapy agent delivery, and in the development of synergistic therapies such as photothermal ablation.
癌症免疫疗法领域已取得重大进展,其目标是激活或调节机体针对癌症的免疫反应。然而,由于全身给药,当前的免疫疗法在安全性和疗效方面存在局限性。在此背景下,利用纳米技术递送癌症疫苗和免疫佐剂具有诸多优势,如靶向递送至免疫细胞、增强治疗效果以及减少不良后果。最近,金纳米颗粒(AuNP)已被探索用作免疫疗法载体,创造了值得进行批判性综述的新的AuNP应用。本综述重点介绍了AuNP介导的免疫疗法开发的最新进展,这些进展利用了AuNP的生物分布、光学特性及其递送肽和寡核苷酸等大分子的能力。已经证明,使用AuNP载体可以提高免疫治疗剂的递送效率和安全性,并且AuNP免疫疗法非常适合与光热消融等现有癌症疗法进行协同联合治疗。
