Cytokine Profiles and Cell Proliferation Responses to Truncated ORF2 Protein in Iranian Patients Recovered from Hepatitis E Infection

Figure 2

IFN-γ ELISPOT responses in HEV-recovered and control groups. IFN-γ ELISPOT responses to the truncated ORF2 protein are significantly higher in the recovered group compared to the controls, while both groups showed good nonspecific stimulation with PHA. The results are shown as spot forming cells per 10⁵ cells (SFC/10⁵ cells).
