What's the influence of laxative agents on mucosal barrier repair?

Research shows that lubiprostone and PEG 3350 can enhance mucosal barrier function in ischemic-injured intestine. Lubiprostone stimulates chloride secretion via ClC-2, recruiting tight junction proteins to the apical-lateral membrane, while PEG 3350 generates an osmotic gradient that drags electrolytes and fluid into the lumen.
