In addition, chemokines also play a part in the fibrotic process of various injury models, for example, theCXCL12-CXCR4 chemokine axis is involved in liver fibrosis (Qin et al., 2018), and CCL2 is involved in pulmonary fibrosis in lung injury (Li et al., 2013). Here, CXCR4 is linked to Hepatic fibrosis.
