Human Breast Milk Promotes the Immunomodulatory Function of Probiotic Lactobacillus reuteri DSM 17938 in the Neonatal Rat Intestine.

ABSTRACT: Breast milk has many growth-promoting and immune-active components, including transforming growth factor-β, lactoferrin, lysozyme, immunoglobulin A, and prebiotics such as the human milk oligosaccharides. Treatment with Lactobacillus reuteri DSM 17938 (LR), a probiotic with immunomodulatory functions, significantly increases regulatory T cells (Tregs) in the intestinal mucosa of newborn suckling rats. In humans, treatment with LR of infants with colic reduces crying optimally if the infants are breast-fed. Therefore, we examined the effects of human breast milk (HBM) on LR-associated immune modulation. Newborn rats were divided into 8 feeding groups, including dam-fed ± LR (106 CFU/kg bw/day, daily), formula-fed ± LR, formula with 20% (v/v) HBM-fed ± LR, and HBM-fed ± LR. Pups were fed by
