Abstract
The steatotic diseases of metabolic dysfunction-associated steatotic liver disease (MASLD), alcohol-associated liver disease (ALD), and chronic hepatitis C (HCV) account for the majority of liver disease prevalence, morbidity, and mortality worldwide. While these diseases have distinct pathogenic and clinical features, dysregulated lipid droplet (LD) organelle biology represents a convergence of pathogenesis in all three. With increasing understanding of hepatocyte LD biology, we now understand the roles of LD proteins involved in these diseases but also how genetics modulate LD biology to either exacerbate or protect against the phenotypes associated with steatotic liver diseases. Here, we review the history of the LD organelle and its biogenesis and catabolism. We also review how this organelle is critical not only for the steatotic phenotype of liver diseases but also for their advanced phenotypes. Finally, we summarize the latest attempts and challenges of leveraging LD biology for therapeutic gain in steatotic diseases. In conclusion, the study of dysregulated LD biology may lead to novel therapeutics for the prevention of disease progression in the highly prevalent steatotic liver diseases of MASLD, ALD, and HCV.
期刊介绍:
Seminars in Liver Disease is a quarterly review journal that publishes issues related to the specialties of hepatology and gastroenterology.
As the premiere review journal in the field, Seminars in Liver Disease provides in-depth coverage with articles and issues focusing on topics such as cirrhosis, transplantation, vascular and coagulation disorders, cytokines, hepatitis B & C, Nonalcoholic Steatosis Syndromes (NASH), pediatric liver diseases, hepatic stem cells, porphyrias as well as a myriad of other diseases related to the liver. Attention is also given to the latest developments in drug therapy along with treatment and current management techniques. Seminars in Liver Disease publishes commissioned reviews. Unsolicited reviews of an exceptional nature or original articles presenting remarkable results will be considered, but case reports will not be published.
