Petrick et al, assessed the associations between HCC and circulating markers of gut barrier integrity: Ig IgA, IgG, and IgM against LPS and flagellin, soluble CD14, and LPS-binding protein in serum taken prediagnostically from 281 cases and 257 controls across the Taiwanese REVEAL‐HBV/HCV cohorts. Here, CD79A is linked to hepatocellular carcinoma.
