摘要：
The gastroduodenal mucosa withstands injury from acid, drugs, foodstuffs, and other factors. Defense mechanisms include pre-epithelial and epithelial barriers, submucosal acid sensors, prostaglandin generation, endogenous protective gases, and other chemical mediators. Recent studies have focused on proteinase-activated receptors and their linkage to prostaglandin formation, as well as on antioxidants targeted to reduce harmful reactive oxygen species. Investigation continues into the protective roles of calcitonin gene-related peptide, hydrogen sulfide, annexin-1, survivin, and methylnicotinamide. This article also summarizes some new findings on the genetics of ulcer formation and the effects of age and gender on mucosal defense and touches on current developments in drugs, including considerations for future therapeutic agents. © Springer Science+Business Media, LLC 2008.
