眼部基因治疗为预防遗传性视网膜营养不良(IRD)患者的视网膜营养不良提供了巨大的潜力。基于腺相关病毒(AAV)的基因转移是最常见和成功的眼部基因传递方法。目前,由于非病毒纳米颗粒的独特性质和生物相容性,许多研究都将其作为一种替代治疗选择。在这里,我们讨论了碳点(CDs)的潜力,一种新型的纳米载体基因传递到视网膜细胞。cd独特的物理化学性质(如光学、电子和催化)使其适用于生物传感、成像、药物和基因传递应用。利用CDs将基因有效地传递到视网膜细胞取决于各种因素,如光致发光、量子产率、生物相容性、大小和形状。在这篇综述中,我们重点介绍了用于合成cd的不同方法,对cd进行分类,细胞内摄入基因负载碳纳米颗粒的各种途径,以及使用cd在眼睛中转移核酸的多项研究。
Ocular gene therapy offers significant potential for preventing retinal dystrophy in patients with inherited retinal dystrophies (IRD). Adeno-associated virus (AAV) based gene transfer is the most common and successful gene delivery approach to the eye. These days, many studies are using non-viral nanoparticles (NPs) as an alternative therapeutic option because of their unique properties and biocompatibility. Here, we discuss the potential of carbon dots (CDs), a new type of nanocarrier for gene delivery to the retinal cells. The unique physicochemical properties of CDs (such as optical, electronic, and catalytic) make them suitable for biosensing, imaging, drug, and gene delivery applications. Efficient gene delivery to the retinal cells using CDs depends on various factors, such as photoluminescence, quantum yield, biocompatibility, size, and shape. In this review, we focused on different approaches used to synthesize CDs, classify CDs, various pathways for the intake of gene-loaded carbon nanoparticles inside the cell, and multiple studies that worked on transferring nucleic acid in the eye using CDs.
