Moreover, a recent systematic review and meta-analysis suggested that chemokines, CCL3, CCL4, CCL5, CCL20, CXCL8 and CXCL11, are implicated in the pathogenesis of non-alcoholic fatty liver disease, post-traumatic stress disorder, and also different types of cancers (130–133). This evidence concerns the gene CCL4 and metabolic dysfunction-associated steatotic liver disease.
