适体是高亲和力的单链DNA/RNA分子,通过称为SELEX(指数富集配体的系统进化)的组合程序产生,其正在成为有前途的诊断和治疗工具。在选择策略中,使用活细胞作为复杂靶标的程序(称为“细胞-SELEX”)已被开发为产生用于重度修饰的细胞表面蛋白的适体的有效手段,从而确保靶标以其天然构象结合。在这里,我们给出了细胞SELEX技术的最新概述,讨论了最新进展,特别关注癌细胞靶向。将简要概述不同协议应用和后SELEX策略的示例。
Aptamers are high affinity single-stranded DNA/RNA molecules, produced by a combinatorial procedure named SELEX (Systematic Evolution of Ligands by Exponential enrichment), that are emerging as promising diagnostic and therapeutic tools. Among selection strategies, procedures using living cells as complex targets (referred as “cell-SELEX”) have been developed as an effective mean to generate aptamers for heavily modified cell surface proteins, assuring the binding of the target in its native conformation. Here we give an up-to-date overview on cell-SELEX technology, discussing the most recent advances with a particular focus on cancer cell targeting. Examples of the different protocol applications and post-SELEX strategies will be briefly outlined.
