Across all stages of liver disease, the gut–vascular barrier (GVB) marker plasmalemma vesicle protein‐1 (PV‐1) correlated with bacterial translocation markers endogenous endotoxin‐core IgA antibodies (EndoCAb) and LPS‐binding protein (LBP) but not with intestinal damage markers intestinal fatty acid binding protein (I‐FABP) and zonulin‐family peptides (ZFP). The gene discussed is FABP2; the disease is liver disorder.
