Core Tip

Core Tip: The integrity of the gastrointestinal mucosa is crucial in gut homeostasis, which depends upon the balance between mucosal injury by destructive factors and healing via protective factors. An excess of destructive agents breaks down the mucosal barrier. Upon injury, under physiological conditions, gastrointestinal mucosa heals itself by complex processes. However, the gut may not heal under pathological conditions. Currently available drugs attempt to minimize or reduce injury to the gastrointestinal tract. Recent studies have focused on improving mucosal defense or directly promoting mucosal repair. This article summarizes the pathobiology of gastrointestinal mucosal healing and reviews potential new therapeutic targets.
