This image of a human intestinal organoid shows enteroendocrine cells (red) embedded within the intestinal cells of the HIO (green).
The hormone peptide YY, also called PYY, can reverse congenital malabsorption in mice, according to new findings in Nature Communications.
With a single PYY injection per day, 80% of the mice survived despite a congenital lack nutrient absorption in their intestines. Normally, only 20% to 30% survive.
The findings, led by Heather McCauley, PhD, Division of Developmental Biology, indicates PYY may eventually become a therapy for human infants born short-gut syndrome, and possibly others who experience malnutrition, or develop intestinal infections.
