Abstract:
T-cell immunity plays a critical role in controlling viral infections, making it essential to identify specific viral targets to develop effective vaccines. In this study, we focused on identifying and understanding the potential effects of different SARS-CoV-2-derived peptides, including spike, nucleocapsid, and ORFs, that have the potential to serve as T-cell epitopes. Assessing T cell response through flow cytometry, we demonstrated that PBMC collected from vaccinated individuals had a significantly higher expression of important biomarkers in controlling viral infection and proper regulation of immune response mediated by T CD4+ and T CD8+ cells stimulated with immunodominant peptides. These data highlight how cellular immune responses to some of these peptides could contribute to SARS-CoV-2 protection due to COVID-19 immunization.
