Abstract:

Alcohol consumption causes significant liver damage, including hepatitis, fibrosis, cirrhosis, and even primary liver carcinoma. Metadoxine (MTDX) is considered to be a beneficial treatment for alcoholic liver disease (ALD) because it accelerates the metabolism and elimination of ethanol. However, the underlying mechanism is not well understood. Here, the rat model of ALD was developed by feeding with 50% ethanol at the dose of 5 g/kg, and samples of serum and liver tissue were collected to test the levels of liver injury and inflammation and evaluate the hepatoprotective function of MTDX in alcohol-induced liver injury. Further investigation on the infiltration of immune cells was performed to understand the potential hepatoprotective mechanism of MTDX in the ALD model. The results showed that MTDX attenuated liver injury, evidenced by decreased levels of alanine transaminase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP). Meanwhile, the liver proinflammatory environment was improved after MTDX treatment, evidenced by decreased levels of TNF-α, IL-6, and NLRP3 in the liver tissue. Furthermore, inhibited infiltrations of macrophages and neutrophils were observed in MTDX-treated ALD rats compared with the untreated ALD rats. Our results indicated that MTDX played an important role in preventing the progression of ALD, and the underlying mechanisms might be related to its function of attenuating liver inflammation by inhibiting immune cell infiltration.
