Background:Human milk contains hyaluronan (HA). Results:Milk HA concentration is highest immediately after delivery. Treatment of epithelium with physiologic levels of milk-derived HA increases intracellular expression of-defensin (in vitroandin vivo) and resistance toSalmonella. Conclusion:Milk HA enhances functional antimicrobial defense mechanisms of the intestinal epithelium. Significance:Milk HA may be a mediator of maternal protection of newborns.
