Human breast milk exosomes attenuate intestinal damage

Background Human breast milk (HBM), which contains an abundant supply of exosomes, is known to prevent necrotizing enterocolitis (NEC). Preterm infants are commonly given pasteurized donor milk when HBM is unavailable. However, pasteurization can disrupt its components. This study investigates the effects of both raw and pasteurized HBM-derived exosomes on intestinal inflammation.
