Highly conserved S-OIV HA peptides elicit strong CD4⁺ T cell responses from donors not previously exposed to the pandemic H1N1 virus. CD4⁺ T cells and autologous DCs were cocultured and assessed by ICCS using the method described in Figure 2. The raw data, as generated in Figure 2, was plotted as line graphs for all eight donors.
