The transcriptomic and multiple evidences reveal that the HCV core protein–intestine‐specific homeobox (ISX) axis promotes a spectrum of metabolic, fibrogenic, and immune modulators (e.g., kynurenine, PD‐L1, and B7‐2), regulating HCV‐infection relevant pathogenic phenotype in vitro and in vivo. This evidence concerns the gene CD86 and infection.
