Induction of IgA and sustained deficiency of cell proliferative response in chronic hepatitis C

Figure 1 Comparison of antibody reactivity to HCV recombinant Co. 120 (A) and NS3 (B) proteins in serum samples from baseline (T = 0) and 6 mo (T = 6) of follow-up. Symbols represent individual values. Only samples showing a positive reactivity are displayed. The horizontal lines represent mean values. Letters over brackets indicate statistical significance (a denotes differences in response magnitude, ^aP = 0.027, ^a'P = 0.0006; b denotes differences in the number of positive samples, ^bP = 0.017, ^b'P = 0.005).
