Core Tip

Core tip: Artesunate (AS) is antimalarial yet potentially anti-inflammatory. We evaluated the effect of AS supplementation on bacterial translocation (BT) and the gut microbiota in a rat model of liver cirrhosis. Dysbiosis of gut microbiota, injury of intestinal mucosal barrier and BT occurred as liver cirrhosis progressed, which might enhance inflammation and aggravate liver injury. AS may have other non-antimalaria effects that modulate gut microbiota, inhibit BT and alleviate inflammation, leading to a reduction in carbon tetrachloride, alcohol and high fat-caused damages to the liver and intestine.
