CX3CL1 and hepatocellular carcinoma: Interestingly, we noticed that FARSB expression was positively related to chemokines CCL26, CX3CL1 and CCR8, a key surface molecule of TH2 cells, which played a role in chemotactic TH2 cells in HCC [72, 73], suggesting that FARSB expression had close connection with TH2 cell infiltration in HCC.
