This study demonstrates that Qinggan Huoxue Recipe (QGHXR), a traditional Chinese medicinal formula, is proved to protect mice from ethanol plus CCl4-induced liver fibrosis. What's more, QGHXR-induced antifibrotic effects are dependent on CXCL16 deactivation, which also suggests that CXCL16 could serve as a novel target for the treatment of liver fibrosis.
Overview of Research Background and PurposeHeavy alcohol consumption causes a wide spectrum of direct liver injury ranging from steatosis, alcoholic hepatitis, cirrhosis and Hepatocellular Carcinoma (HCC). Globally, 25% of cirrhosis deaths in 2019 were estimated to be associated with alcohol [1]. For each region, the highest percentage of cirrhosis deaths associated with alcohol was in Europe (42%), while the lowest was in the Eastern Mediterranean region (8%) [1]. Fibrosis is thought to initiate in the perivenular area, and continued fibrosis leads to scar tissue formation that replaces liver parenchyma, leading to cirrhosis ultimately [2]. In recent years, genetic studies have identified new genes highly associated with alcoholic liver fibrosis. Many of these genes regulate key inflammatory pathways that are dysregulated in the disease [3]. CXCL16 is a chemotactic cytokine belonging to the α-chemokine subfamily, functioning as a ligand for the CXC Chemokine Receptor 6 (CXCR6) [4]. CXCL16 plays a significant role in the progression
