Compatibility with Fructus Ligustri Lucidi Effectively Mitigates Idiosyncratic Liver Injury of Epimedii Folium by Modulating NOD-like Receptor Family Pyrin Domain Containing 3 Inflammasome Activation

引用

World Journal of Traditional chinese Medicine 2024年第2期10卷 159-170页

作者： Xiao-Mei Zhao Zhi-Xin Wu Yan Wang Ying-Jie Xu Ye Xiu Xu Dong Jun-Jie Li Gui-Ji Lv Si-Hao Wang Yu-Rong Li Zhao-Fang Bai Xiao-He Xiao Department of Pharmacy Chengdu University of Traditional Chinese MedicineChengdu China Department of Hepatology The Fifth Medical Center of PLA General HospitalBeijingChina Department of Military Patient Management The Fifth Medical Center of PLA General HospitalBeijingChina Department of Hepatology China Military Institute of chinese Materia The Fifth Medical Center of PLA General HospitalBeijingChina Departmentof Hepatology National Key Laboratory of Kidney DiseasesBeijingChina

Background: Idiosyncratic drug-induced liver injury(IDILI) is a serious side effect of drugs, Epimedii Folium(EF) is unequivocally implicated in idiosyncratic liver injury onset, potentially due to its ability to perturb the NOD-like receptor family pyrin domain containing 3(NLRP3) inflammasome. Fructus Ligustri Lucidi(FLL), a frequently used medicinal combination with EF, has not yet been investigated for its ability to ameliorate EF-associated hepatotoxicity. Aims and Objectives: Study on the mechanism of compatibility of FLL to alleviate liver injury caused by EF. Materials and Methods: Western blot was used to determine the expression of related proteins, ELISA was used to detect the secretion of related inflammatory factors IL-1β, IL-18, IL-6 and TNF-α, liver injury indexes were detected and liver pathological tissue staining was used to evaluate the liver injury. Results: Our results demonstrated that EF exerted a particular augmenting effect on the stimulation of the NLRP3 inflammasome mediated by nigericin or ATP, whereas FLL suppressed the NLRP3 inflammasome stimulation. Furthermore, an equal EF to FLL ratio significantly reduced the stimulatory effects of EF. Moreover, EF has the potential to induce hepatic injury and augment pro-inflammatory cytokine synthesis in rats subjected to LPS. However, when combined with FLL, the detrimental effects of EF were mitigated. Conclusions: FLL possesses the capacity to attenuate EF-associated hepatotoxicity by suppressing EF-triggered NLRP3 inflammasome activation. Thus, FLL holds promise for improving the clinical safety profile of EF, shedding light on the potential of compatibility and detoxification theories in traditional chinese medicine.
