Figures 1(a), 1(b), and 1(c) illustrate the positive expression of AIM2, caspase-1, and IL-1β, respectively, in these patients, and Figure 1(d) shows the negative expression of AIM2, caspase-1, and IL-1β with PBS substituted primary antibody in HBV-GN tissue. This evidence concerns the gene CASP1 and ganglioneuroma.
