Description

The importance of antiviral CD8+ T cell recognition of alternative reading frame (ARF)–derived peptides is uncertain. In this study, we describe an epitope (NS1-ARF21–8) present in a predicted 14-residue peptide encoded by the +1 register of NS1 mRNA in the influenza A virus (IAV). NS1-ARF21–8 elicits a robust, highly functional CD8+ T cell response in IAV-infected BALB/c mice. NS1- ARF21–8 is presented from unspliced NS mRNA, likely from downstream initiation on a Met residue that comprises...[Show more]
