Summary: Nonalcoholic fatty liver disease (NAFLD) is a common chronic liver disease with a wide range of severity, from simple hepatic steatosis to nonalcoholic steatohepatitis (NASH). NASH can lead to liver fibrosis, cirrhosis, and hepatocellular carcinoma, making hepatic fibrosis an important predictor of outcomes. Recent advancements in understanding the activation and inactivation of hepatic stellate cells, which drive fibrosis development, have shed light on the disease progression in NAFLD/NASH.

Summary: Schistosomiasis is a zoonotic parasitic disease that causes liver fibrosis, which endangers human health. NK cells play a crucial role in inhibiting liver fibrosis, but their function is significantly inhibited in Schistosoma japonicum infection. This study found that the inhibitory receptor Tigit is highly expressed on NK cells during infection, and Tigit knockout enhances NK cell function and reduces liver fibrosis in schistosomiasis.

Summary: The deficiency of HSCs-specific Loxl1 can prevent CCl4-induced hepatic fibrosis and reduce fibrosis and inflammation in liver tissue, with ITGA8/FAK/PI3K/AKT/HIF1a being essential for the function and expression of LOXL1. The study suggests novel mechanisms and potential targets for the treatment of fibrosis in the future.

Summary: Liver fibrosis is caused by excessive proliferation and collagen production by hepatic stellate cells (HSCs) due to chronic liver injury. Hydroxyurea, an anti-proliferative drug, showed inhibitory effects on HSC proliferation and fibrosis development in both in vitro and in vivo experiments. This study provides evidence for the therapeutic potential of hydroxyurea in treating liver fibrosis.

Summary: In this study, the researchers found that TRIM26 promotes HSCs ferroptosis through mediating the ubiquitination of SLC7A11, thereby suppressing liver fibrosis. The targeted suppression of SLC7A11 by TRIM26 could be a novel therapeutic strategy for liver fibrosis.

Summary: This study investigates the antifibrotic properties of T-96 and its underlying molecular mechanisms. The results show that T-96 can inhibit the proliferation, migration, and activation of hepatic stellate cells and alleviate liver injury, inflammation, and fibrosis progression in a CCl4-induced liver fibrosis mouse model. Mechanistic studies reveal that the antifibrotic effect of T-96 is mediated by suppressing the expression of AGAP2 and inhibiting the phosphorylation of FAK and AKT.

Summary: This article reports a novel strategy for treating liver fibrosis by reprogramming activated Hepatic Stellate Cells (aHSCs) into quiescent Hepatic Stellate Cells (qHSCs) using siRNA-loaded lipid nanoparticles (LNPs). The optimized LNPs enable ligand-free, selective, and potent siRNA delivery to aHSCs, resulting in the reversal of liver fibrosis and restoration of normal liver function in mice. This scalable and ligand-free platform has potential for clinical translation.

Summary: This study aimed to investigate the changes in nerve factors and neurokines and their relation to hepatic stellate cells (HSCs) in liver fibrosis. The results showed significantly increased expression levels of neurokines in both human and animal liver fibrosis. It was also observed that there is interaction between nerve cells and HSCs, and nerve cells produce neurogenic substances that promote liver fibrosis and HSC activation.

Summary: Activated hepatic stellate cells (aHSCs) play a critical role in liver fibrosis. The study introduces a nano platform called silibinin albumin nanocrystals (SLB-HSA NCs) for targeted therapy of liver fibrosis. The SLB-HSA NCs demonstrated a uniform particle size distribution of approximately 60 nm, high loading efficiency, and increased cellular uptake by aHSCs through SPARC-mediated endocytosis. In pharmacokinetic study, SLB-HSA NCs exhibited enhanced bioavailability compared with free SLB. Furthermore, they showed significant antifibrotic effects in hepatic fibrosis mice.
