Core Tip

Core tip: In this study, we reported for the first time that intraperitoneal injection of irisin could relieve intestinal injury in mice with acute pancreatitis (AP). AP was induced in male adult mice by two hourly intraperitoneal injections of L-arginine. At 2 h after the last injection of L-arginine, irisin (50 or 250 μg/kg body weight) or 1 mL normal saline (vehicle) was administered through intraperitoneal injection. Irisin alleviated intestinal and systemic inflammatory reactions by inhibiting intestinal endoplasmic reticulum stress and oxidative stress in mice with AP, reduced the degree of intestinal tissue apoptosis and injury and finally alleviated the condition of pancreatitis.
