Intraperitoneal injection but not oral administration of ellagic acid: A novel immunomodulator via targeting casein kinase 2 signaling pathway

引用

Food Science and Human Wellness 2024年

作者： Wen-Hui Qi Bing Han Ting-Ting Cui Pei-Xin Shen Zhuo-Hua Zhao Ya-ping yan Li-Bin Wang Xin-Yu Lu Yuan Zhang Xing Li Key Laboratory of Medicinal Resources and Natural Pharmaceutical Chemistry (Shaanxi Normal University)， The Ministry of Education College of Life Sciences， Shaanxi Normal University Department of Pharmacology， School of Pharmacy， Fourth Military Medical University The Nervous System Disease Diagnosis and Treatment Engineering Technology Research Center of Ningxia School of Medical Technology， Xi'an Medical University

Immunosuppressants currently approved for the treatment of autoimmune diseases and organ transplant rejection present diverse adverse effects that impair the life quality of patients. Therefore， the development of novel immunomodulators with high efficiency and low toxicity is essential. Ellagic acid (EA)， a natural polyphenol compound widely distributed in berries， is metabolically transformed by gut microbiome to exert systemic health benefits. Here， we identified that intraperitoneal administration of EA with no cytotoxicity， beyond its well-known oral metabolic fate， effectively decreased clinical severity and CNS inflammation/demyelination in experimental autoimmune encephalomyelitis (EAE)， a mouse model of an autoimmune disease multiple sclerosis (MS). Interestingly， intraperitoneal EA administration at incredibly low doses (0.1 mg/kg/d) is dose-sparing with fingolimod (FTY720)， the first FDA-approved oral drug for MS. In addition， intraperitoneal EA also ameliorated the brain damage in a neuromyelitis optica (NMO) model， and significantly prevented the immune rejection of allograft skin graft. Evidence from pharmacological studies combined with RNA-seq indicate that prototype EA functions by a mechanism that involves direct inhibition of casein kinase II (CKII) to suppress the expression of IL-17 and promote the expression of Cpt1a to regulate Th17 differentiation. In conclusion， our study demonstrates that the prototype EA entering the blood circulation acts as a novel therapeutic immunomodulator for the treatment of autoimmune diseases and transplant rejection through the CKⅡ-mediated JAK/STAT/Cpt1a signaling pathway.

目的观察基于超声评分系统联合临床特征构建的列线图预测凶险性前置胎盘(PPP)患者产后出血(PPH)的价值。方法回顾性分析342例接受剖宫产PPP孕妇,以243例产前接受超声评分系统评估者为观察组、99例接受常规超声者为对照组。比较组间孕妇基线资料及母儿结局差异;记录观察组产后24 h内出血量、判断是否发生PPH(≥1000 ml),并按8∶2比例分为训练集(n=194,含107例PPH和87例非PPH)及测试集(n=49,含29例PPH和20例非PPH)。采用单因素及多因素logistic回归分析评估训练集临床及超声系统评分,筛选PPP患者发生PPH的独立危险因素并构建列线图,评估其预测效能、拟合度及临床有效性。结果观察组产后24 h内出血量、输注红细胞悬液量、手术时间、住院时间及分娩孕周与对照组差异均有统计学意义(P均<0.05)。产前体质量指数≥28 kg/m^(2)、引产/流产次数≥3及超声系统评分≥10均为PPP患者发生PPH的独立危险因素(P均<0.05);以之构建的列线图拟合度佳,预测测试集PPP患者发生PPH的曲线下面积为0.81,且阈值为0.22~0.98时临床净获益大于0。结论超声评分系统联合临床特征列线图能有效预测PPP患者发生PPH。
