摘要:Strategies to manipulate gut microbiota in infancy have been considered to prevent the development of allergic diseases later in life. We previously demonstrated that maternal dietary supplementation with fructo-oligosaccharide (FOS) during pregnancy and lactation modulated the composition of gut microbiota and diminished the severity of spontaneously developing atopic dermatitis-like skin lesions in the offspring of NC/Nga mice. The present study tested whether dietary FOS affects contact hypersensitivity (CHS), another model for allergic skin disease, in NC/Nga mice. In experiment 1, 5-wk-old female NC/Nga mice were fed diets either with or without FOS supplementation for 3 wk and then received 2,4-dinitrofluorobenzene (DNFB) on the ear auricle 5 times at 7-d intervals. FOS supplementation reduced CHS response as demonstrated by ear swelling. Quantitative RT-PCR analysis showed that mRNA levels for interleukin (IL)-10, IL-12p40, and IL-17 in the lesional ear skin were significantly lower in mice fed FOS. In experiment 2, female NC/Nga mice were fed diets either with or without FOS during pregnancy and lactation. After weaning, offspring were fed the diets supplemented with or without FOS. Three weeks after weaning, offspring received DNFB on the ear auricle 4 times at 7-d intervals. Although FOS supplementation after weaning reduced ear swelling, maternal FOS consumption was ineffective in offspring. The present data suggest that dietary FOS reduces CHS while maternal FOS consumption is ineffective in offspring of DNFB-treated NC/Nga mice.
