FIG. 8.
Effects of HP-OVA on IFN-γ secretion by human PBMCs stimulated with PHA or not stimulated. (A) IFN-γ secretion of human PBMCs in the presence of HP-OVA at graded concentrations and 5 μg/ml of PHA as a control. (B) Effects of HP-OVA on IFN-γ secretion by human PBMCs stimulated with PHA (5 μg/ml). The spots of IFN-γ-producing cells in PBMCs were counted and are expressed as the number of spot-forming cells (SFCs) per 106 PBMCs. Each sample was tested in triplicate, and the data are presented as means ± standard deviations.
