Notably, the results showed that either the peptide mixture or single peptide could induce IFN-γ production from the PBMCs of HFRS patients in vitro (Figure 3A), indicating that each of the seven HTNV GP epitopes could effectively elicit epitope-specific IFN-γ-secreting T-cell responses. The gene discussed is IFNG; the disease is hemorrhagic fever with renal syndrome.
