CXCL2 and fatty liver disease: Compared with vehicle-treated mice, mice fed ethanol and receiving antiretrovirals developed less liver injury, indicated by a lower level of serum alanine amino-transferase (Figure 5G), decreased hepatic steatosis (Figure 5, H and I), and reduced liver inflammation, with decreased expression of the inflammatory chemokines, chemokine (C-X-C motif) ligand-1 (Cxcl1) and Cxcl2 (Figure 5J).
