Core Tip

Core Tip: Stress-related gastric mucosal damage remains an issue for critical care patients. As an endogenous peptide, intestinal trefoil factor was found to alleviate both macroscopic and microscopic gastric mucosal damage in vivo induced by acute stress stimulation and promote mucosal epithelial cell survival, accelerate wound closure, and preserve mucosal integrity in vitro. Akt signaling pathway could play an essential role. Therefore, intestinal trefoil factor is a promising candidate for prevention and treatment of stress-induced gastric mucosal damage.
