Influenza A viruses (IAVs) exhibit rapid mutation and high infectivity, leading to a considerable number of cases and deaths globally. Thus, the development of broad-spectrum inhibitors is of paramount significance. In this study, targeting the hemagglutinin (HA) of IAVs, a set of high-affinity and specific aptamers, namely Apt(HA)-1, Apt(HA)-4, Apt(HA)-9, Apt(HA)-25, and Apt(HA)-93520, were obtained through CE-SELEX. The dissociation constants (KD) of this group of aptamers [Apts(HA)] with the HA protein were determined by the SPR method to be 25.9, 44.8, 50.7, 54.0, and 45.2 nmol·L-1, respectively. Apts(HA) can recognize and detect the internationally common influenza virus strains A/PR/8/34 (H1N1) and A/FM/1/47 (H1N1), as well as the clinically isolated Tamiflu-resistant strain A/Liaoningzhenxing/1109/2010 (H1N1), amantadine-resistant strains A/Hunanzhuhui/1222/2010 (H3N2) and A/Fujiantongan/196/2009 (H3N2), and possess broad-spectrum inhibitory effects on influenza viruses. These aptamer inhibitors feature strong in vitro accessibility, good stability, simple structure, and small size. This study not only developed novel broad-spectrum aptamers against IAVs, exerting extensive inhibitory effects on various IAVs, but also paved the way for an effective strategy in the development of universal virus inhibitors.

甲型流感病毒(IAVs) 具有快速突变和高度传染性, 在全球范围内引起大量发病和死亡, 因此开发广谱的抑制剂至关重要。本研究以IAVs血凝素(HA) 为靶点, 通过CE-SELEX技术筛选获得了一组高亲和力、特异性适配体Apt(HA)-1、Apt(HA)-4、Apt(HA)-9、Apt(HA)-25与Apt(HA)-93520, 通过SPR方法测定该组适配体[Apts(HA)] 与HA蛋白的解离常数(KD) 分别为25.9、44.8、50.7、54.0和45.2 nmol·L-1。Apts(HA) 可以识别与检测流感病毒国际通用株A/Puerto Rico/8/34 (H1N1) 和A/Fort Monmouth/1/1947 (H1N1), 以及临床分离达菲耐药株A/Liaoningzhenxing/1109/2010 (H1N1)、金刚烷胺耐药株A/Hunanzhuhui/1222/2010 (H3N2) 和A/Fujiantongan/196/2009 (H3N2), 并具有广谱的流感病毒抑制作用。该适配体抑制剂具有体外筛选易获得、稳定性好、结构简单、体积小等优点。本研究不仅开发了针对IAVs的新型广谱适配体, 对各种IAVs具有广泛的抑制作用, 而且为开发通用病毒抑制剂开辟了一种有效的策略。
