The HCV core protein plays an essential role in HCV pathogenesis, and as such is an attractive target for antiviral therapy. Aptamers, which are synthetic nucleic acid molecules that bind specifically to proteins or other targets, have shown promise as therapeutic agents for a range of diseases, including viral infections. In this study, we will investigate the antiviral activity of aptamers targeting the HCV core protein.Introduction:HCV is a blood-borne virus that affects an estimated 71 million people worldwide. Chronic HCV infection can lead to liver cirrhosis, liver failure, and hepatocellular carcinoma. Despite the availability of direct-acting antiviral (DAA) therapies that can cure most HCV infections, access to these treatments remains limited in many parts of the world. In addition, the emergence of DAA-resistant strains of HCV highlights the ongoing need for new therapeutic agents.The HCV core protein is a multifunctional protein that plays a key role in HCV replication and pathogenesis. It forms the nucleocapsid of the virus, interacts with viral and host proteins, and modulates host cell signaling pathways. As such, the core protein is an attractive target for antiviral therapy.Aptamers are short, single-stranded nucleic acid molecules that can fold into specific three-dimensional structures, allowing them to bind specifically to their targets. They have several advantages over traditional small-molecule drugs, including high specificity and affinity, low toxicity, and ease of manufacturing.In this study, we will investigate the antiviral activity of...
