Gut-derived lipopolysaccharide (LPS) leaking through the dysfunctional intestinal barrier contributes to the onset of non-alcoholic steatohepatitis (NASH) by triggering inflammation in the liver. In the present study, a combination consisting of polysaccharide (A), chlorogenic acid (C), and geniposide (G) (together, ACG), was shown to ameliorate NASH in mice and reduce hepatic LPS signaling and endotoxemia without decreasing the abundance of identified Gram-negative bacteria through restoring the intestinal tight junctions. Our data indicated that inhibition of LPS gut leakage by the ACG combination contributed to its amelioration of NASH.
肠源性脂多糖(LPS)通过功能失调的肠道屏障渗漏,触发肝脏炎症,导致非酒精性脂肪性肝炎(NASH)的发生。在本研究中,一种由多糖(A)、绿原酸(C)和栀子苷(G)组成的混合物(简称 ACG),通过恢复肠道紧密连接,改善了小鼠的 NASH 并降低了肝内 LPS 信号和内毒素血症,而没有减少鉴定出的革兰氏阴性菌的丰度。我们的数据表明,ACG 混合物抑制 LPS 肠漏有助于改善 NASH。
