Alcohol-associated liver disease (ALD) is a major cause of chronic worldwide, and comprises spectrum several different disorders, including simple steatosis, steatohepatitis, cirrhosis, superimposed hepatocellular carcinoma. Although tremendous progress has been made in the field ALD over last 20 years, pathogenesis remains obscure, there are currently no FDA-approved drugs for treatment ALD. In this Review, we discuss new insights into therapeutic targets ALD, utilizing study multiomics other cutting-edge approaches. The potential translation these studies clinical practice therapy deliberated.

Liver diseases: epidemiology, causes, trends and predictions

Signal Transduction and Targeted Therapy, Journal Year: 2025, Volume and Issue: 10(1)

Published: Feb. 4, 2025

Abstract As a highly complex organ with digestive, endocrine, and immune-regulatory functions, the liver is pivotal in maintaining physiological homeostasis through its roles metabolism, detoxification, immune response. Various factors including viruses, alcohol, metabolites, toxins, other pathogenic agents can compromise function, leading to acute or chronic injury that may progress end-stage diseases. While sharing common features, diseases exhibit distinct pathophysiological, clinical, therapeutic profiles. Currently, contribute approximately 2 million deaths globally each year, imposing significant economic social burdens worldwide. However, there no cure for many kinds of diseases, partly due lack thorough understanding development these Therefore, this review provides comprehensive examination epidemiology characteristics covering spectrum from conditions manifestations. We also highlight multifaceted mechanisms underlying initiation progression spanning molecular cellular levels networks. Additionally, offers updates on innovative diagnostic techniques, current treatments, potential targets presently under clinical evaluation. Recent advances pathogenesis hold critical implications translational value novel strategies.

Alcohol and the mechanisms of liver disease

Journal of Gastroenterology and Hepatology, Journal Year: 2023, Volume and Issue: 38(8), P. 1233 - 1240

Published: July 9, 2023

Abstract Alcoholic liver disease (ALD), which is a leading cause of morbidity and mortality worldwide, covers large spectrum injuries ranging from simple steatosis to steatohepatitis, advanced fibrosis, cirrhosis, hepatocellular carcinoma. The pathogenesis ALD includes genetic epigenetic alterations, oxidative stress, acetaldehyde‐mediated toxicity cytokine chemokine‐induced inflammation, metabolic reprogramming, immune damage, dysbiosis the gut microbiota. This review discusses progress in molecular mechanism ALD, could provide evidence for further research on potential therapeutic strategies targeting these pathways.

Gut-liver axis: Recent concepts in pathophysiology in alcohol-associated liver disease

Hepatology, Journal Year: 2024, Volume and Issue: 80(6), P. 1342 - 1371

Published: May 1, 2024

The growing recognition of the role gut microbiome’s impact on alcohol-associated diseases, especially in liver disease, emphasizes need to understand molecular mechanisms involved governing organ-organ communication identify novel avenues combat diseases. gut-liver axis refers bidirectional and interaction between liver. Intestinal microbiota plays a pivotal maintaining homeostasis within axis, this significant disease. intricate intestine involves multiple cellular components each organ that enable them carry out their physiological functions. In review, we focus approaches understanding how chronic alcohol exposure impacts microbiome individual cells intestine, as well ethanol machinery required for intraorgan interorgan communication.

Effects of elafibranor on liver fibrosis and gut barrier function in a mouse model of alcohol-associated liver disease

World Journal of Gastroenterology, Journal Year: 2024, Volume and Issue: 30(28), P. 3428 - 3446

Published: July 24, 2024

BACKGROUND Alcohol-associated liver disease (ALD) is a leading cause of liver-related morbidity and mortality, but there are no therapeutic targets modalities to prevent ALD-related fibrosis. Peroxisome proliferator activated receptor (PPAR) α δ play key role in lipid metabolism intestinal barrier homeostasis, which major contributors the pathological progression ALD. Meanwhile, elafibranor (EFN), dual PPARα PPARδ agonist, has reached phase III clinical trial for treatment metabolic dysfunction-associated steatotic primary biliary cholangitis. However, benefits EFN ALD unknown. AIM To evaluate inhibitory effects on fibrosis gut-intestinal dysfunction an mouse model. METHODS was induced female C57BL/6J mice by feeding 2.5% ethanol (EtOH)-containing Lieber-DeCarli liquid diet intraperitoneally injecting carbon tetrachloride thrice weekly (1 mL/kg) 8 weeks. (3 10 mg/kg/day) orally administered during experimental period. Histological molecular analyses were performed assess effect steatohepatitis, fibrosis, integrity. The HepG2 lipotoxicity Caco-2 function evaluated cell-based assays. RESULTS hepatic steatosis, apoptosis, model significantly attenuated treatment. promoted lipolysis β-oxidation enhanced autophagic antioxidant capacities EtOH-stimulated cells, primarily through activation. Moreover, inhibited Kupffer cell-mediated inflammatory response, with blunted exposure lipopolysaccharide (LPS) toll like 4 (TLR4)/nuclear factor kappa B (NF-κB) signaling. improved hyperpermeability restoring tight junction proteins autophagy inhibiting apoptosis proinflammatory responses. protective cells predominantly mediated CONCLUSION reduced accumulation enhancing hepatocyte capacities, suppressing LPS/TLR4/NF-κB-mediated responses function.

Inflammation in Alcohol-Associated Hepatitis: Pathogenesis and Therapeutic Targets

Cellular and Molecular Gastroenterology and Hepatology, Journal Year: 2024, Volume and Issue: 18(3), P. 101352 - 101352

Published: Jan. 1, 2024

Alcohol-associated hepatitis (AH) is an acute-on-chronic liver injury that occurs in patients with chronic alcohol-associated disease (ALD). Patients severe AH have high short-term mortality and lack effective pharmacologic therapies. Inflammation believed to be one of the key factors promoting progression has been actively investigated as therapeutic targets over last several decades, but no inflammatory identified so far. In this review, we discuss how cells mediators produced by these contribute development AH, focus on neutrophils macrophages. The crosstalk between nonparenchymal pathogenesis elaborated. We also deliberate application recent cutting-edge technologies characterizing inflammation AH. Finally, potential for are briefly summarized.
