Abstract

Virus-specific cytotoxic T lymphocytes (CTLs) are crucial for the control of respiratory syncytial virus (RSV) infection. This study has identified CTL epitopes of the RSV N protein in healthy subjects. We screened the primary structure of the N protein for HLA-A(*)0201-binding amino acid consensus motifs, identifying three peptides designated as N-RSV1, N-RSV2, and N-RSV3. These peptides were used to generate CTL lines by stimulating human HLA-A(*)02.01 peripheral blood mononuclear cells (PBMCs) in vitro. These CTL lines were then characterized by performing CTL chromium release assays and IFN-γ secretion detection by intracellular cytokine staining. N-RSV1 and N-RSV3 peptides elicited the strongest cytolytic activity against RSV-infected cells and they could be useful epitopes for the analysis of CTL responses to RSV and for understanding immune-induced disease pathogenesis. © 2007 Mary Ann Liebert, Inc.
