Pro-inflammatory stress is inherent in any cells that are subject to damage or threat of damage. It defined by a number universal components, including oxidative stress, cellular response DNA damage, unfolded protein mitochondrial and endoplasmic reticulum changes autophagy, inflammasome formation, non-coding RNA response, formation an inducible network signaling pathways, epigenetic changes. The presence receptor secretory phenotype many the cause tissue pro-inflammatory stress. key phenomenon determining occurrence classical inflammatory focus microvascular (exudation, leukocyte migration alteration zone). This same reaction at systemic level leads development life-critical inflammation. From this standpoint, we can characterize common mechanisms pathologies differ their clinical appearance. division inflammation into alternative variants has deep evolutionary roots.

The development of liver fibrosis primarily determines quality life as well prognosis. Animal models are often used to model and understand the underlying mechanisms human disease. Although organoids can be simulate organ disease, technology still faces significant challenges. Therefore animal irreplaceable at this stage. Currently, in vivo classified into five categories based on etiology: chemical, dietary, surgical, transgenic, immune. There is a wide variety with varying efficacy, which have different implications for proper understanding disease effective screening therapeutic agents. no high-quality literature recommending most appropriate models. In paper, we will describe progress commonly terms their mechanisms, applications, advantages disadvantages, recommend research purposes.

As cell-free nanotherapeutics, extracellular vesicles derived from mesenchymal stem cells (MSC-EVs) have shown potential therapeutic action against liver diseases. However, their effects on autoimmune hepatitis (AIH) are not yet well understood. In this study, we utilized a well-established concanavalin A (Con A)-induced fulminant mouse model to investigate the of MSC-EVs AIH. We found that provide significant protection Con A-induced in C57BL/6 male mice, with effectiveness being critically dependent gut microbiota. modulate composition microbiota, particularly by increasing abundance norank_f__Muribaculaceae, and impact metabolic profiles, leading amelioration injury. The identification Acetyl-DL-Valine as protective metabolite underscores targeting gut‒liver axis interactions Overall, our data demonstrate exhibit nanotherapeutic new insights into treatment hepatitis.

Abstract Acute severe autoimmune hepatitis (AS‐AIH) is characterized by rapid progression and poor prognosis, with a current lack of effective targeted treatments. Stem cell therapy has demonstrated significant therapeutic promise across various diseases. However, the intricate pathogenesis AS‐AIH hindered widespread utilization mesenchymal stem cells (MSCs) in this domain. Herein, it that necroptosis, as primary mode death AIH, crucial causing AS‐AIH. Inflammatory macrophages are population involved necroptosis. Inhibition specificity protein 1/sphingosine kinase 1/sphingosine‐1‐phosphate (SP1/SK1/S1P) axis responsible for phenomenon, leading to excessive activation intrahepatic immune system aggravating liver damage. Furthermore, S1P/S1PR2/YAP key pathway initiating regeneration during S1P synthesized hepatocytes source, process also regulated SP1/SK1 axis. MSCs promote synthesis through delivery SP1, which inhibits necroptosis synergistically enhances regeneration. In addition, same mechanism, further aiding These findings unveil core provide theoretical foundation using potential modality.

Immune-mediated hepatic injury plays a key role in the initiation and pathogenesis of diverse liver diseases. However, treatment choice for immune-mediated remains limited. Corilagin, natural ellagitannin extracted from various traditional Chinese medicines, has been demonstrated to exhibit multiple pharmacological activities, such as anti-inflammatory, anti-tumor, hepatoprotective properties. The present study aimed investigate effects corilagin on using murine model concanavalin A (Con A)-induced hepatitis, which is well-characterized acute hepatitis. Herein, mice were administered (25 mg/kg) intraperitoneally twice at 12 h intervals, 1 later, challenged with Con (20 mg/kg body weight); serum samples collected after h. results showed that significantly increased survival reduced alanine transaminase (ALT) aspartate aminotransferase (AST) levels. In addition, markedly improved histopathological damage, hepatocyte apoptosis, oxidative stress liver. activation M1 macrophages mononuclear cells was also compared control group. expression macrophage-associated proinflammatory cytokines genes, including interleukin (IL)-6, IL-12, inducible nitric oxide synthase (iNOS), decreased treatment. Finally, regulated macrophage polarization by modulating mitogen-activated protein kinases (MAPK), nuclear factor (NF)-κB, interferon regulatory (IRF) signaling pathways. Thus, findings indicate protects A-induced limiting via MAPK, NF-κB, IRF pathways, suggesting possible injury.
