Abstract:
Toll-like receptor 4 (TLR4) plays an important role as a key signal-receiving transmembrane protein molecule in the liver, and substances that target the liver exert therapeutic effects via TLR4-related signaling pathways. This article provides a comprehensive review of targeting the TLR4 signaling axis to play an important role in the liver based on endogenous substances. Articles were divided into 5 major types of liver disease, acute liver injury, viral hepatitis, alcoholic and non-alcoholic liver disease, cirrhosis, and liver cancer, to elucidate how various endogenous substances affect the liver via the TLR4 pathway and the important role of the pathway itself in liver-related diseases to discover the potential therapeutic implications of the TLR4-related pathway in the liver. The results indicate that activation of the TLR4-related signaling axis primarily plays a role in promoting disease progression in liver-related diseases, and the TLR4/MyD88/NF-κB axis plays the most dominant role. Therefore, exploring the full effects of drugs targeting the TLR4-related signaling axis in the liver and the new use of old drugs may be a new research direction.
Insights
Targeting Toll-like receptor 4 (TLR4) signaling in the liver is crucial for treating liver diseases. The TLR4/MyD88/NF-κB pathway often promotes disease progression, suggesting new therapeutic strategies.
Area of Science:
- Immunology
- Hepatology
- Molecular Biology
Background:
- Toll-like receptor 4 (TLR4) is a key transmembrane protein involved in liver signaling.
- TLR4-mediated pathways are critical for therapeutic effects targeting the liver.
Purpose of the Study:
- To comprehensively review the role of endogenous substances targeting the TLR4 signaling axis in various liver diseases.
- To elucidate the impact of TLR4 pathways on liver disease progression and identify therapeutic implications.
Main Methods:
- Systematic review of literature on liver diseases including acute liver injury, viral hepatitis, alcoholic and non-alcoholic fatty liver disease, cirrhosis, and liver cancer.
- Analysis of how endogenous substances modulate the TLR4 pathway in the liver.
- Evaluation of the role of TLR4 signaling in disease pathogenesis.
Main Results:
- Activation of the TLR4 signaling axis generally promotes disease progression across major liver disease types.
- The TLR4/MyD88/NF-κB signaling cascade is identified as the most dominant pathway in liver disease progression.
- Endogenous substances significantly influence liver function through TLR4-dependent mechanisms.
Conclusions:
- Targeting the TLR4 signaling axis presents a promising therapeutic avenue for liver diseases.
- Further research into the comprehensive effects of TLR4-targeting drugs and repurposing existing medications is warranted.
