GLP-2 is studied to act through three routes that together drive gut lining maintenance and repair.
It binds the GLP-2 receptor on gut cells, a signal studied for triggering the intestinal lining to grow taller and thicker.
By expanding the absorptive surface of the intestine, it is studied for helping the gut pull more nutrients and fluid from food.
It is investigated for strengthening the gut barrier and slowing lining cell death, which may support recovery of damaged tissue.
