Benefits of technology

[0011]Recently, new techniques have become available to chemically synthesise specific types of NDO identical to specific human NDO, thereby offering the opportunity to test the immunomodulatory capacity of specific human NDO in in vitro and in vivo assays.
[0012]The inventors unexpectedly have found that fucosyllactose (FL), an oligosaccharide abundantly present in human breast milk and with a relatively simple structure,

Problems solved by technology

Because of their complex and polymorphic structure, large-scale synthesis is complicated.
It is therefore not yet

[0041]Nutritional Composition

[0042]Preferably the composition comprising fucosyllactose is a nutritional composition. The composition of the present invention is not human milk. The present composition is preferably enterally administered, more preferably orally.

[0043]The present composition is preferably a nutritional formula, preferably an infant formula. The present composition can be advantageously applied as a complete nutrition for infants. The present composition preferably comprises a lipid component, protein component and carbohydrate component and is preferably administered in liquid form. The present invention includes dry food, preferably a powder, which is accompanied with instructions as to admix said dry food mixture with a suitable liquid, preferably with water.

[0044]The present invention advantageously provides a composition wherein the lipid component provides 5 to 50% of the total calories, the protein component provides 5 to 50% of the total calories, and the dig...

[0059]Materials and Methods

[0060]6-8 Weeks old female C57BL / 6 mice (Charles River) received semi-purified AIN-93G-based diets (Research Diet Service, Wijk bij Duurstede, the Netherlands), comprising 1) 2 wt % beta-galacto-oligosaccharide (GOS; source Vivinal GOS, Borculo Domo), fructo-oligosaccharide (FOS; source RaftilineHP, Orafti) and galacturonic acid oligosaccharide (Source AOS) in a 9:1:1.1 ratio. AOS are produced from pectin (Südzucker AG, Mannheim, Germany), with a DP of 1-20. It consists of approximately 75% galacturonic acid oligomers, based on total weight;

[0062]3) 1 wt % 3′-sialyl lactose (3′-SL), or

[0063]4) 1 wt % 2′-fucosyllactose (2′-FL).

[0064]All groups were compared to the unsupplemented control diet. Dietary supplementation started 14 days before the first vaccination and lasted until the end of the experiment, 31 days after the first vaccination.

[0065]Vaccination experiments were performed using Influvac (Solvay Pha...

Abstract

The invention concerns nutritional compositions with fucosyllactose for use in stimulation of NK cells. The composition is suitable for infants.

Description

FIELD OF THE INVENTION[0001]The present invention relates to infant nutrition with non-digestible oligosaccharides, in particular to the use thereof for stimulating the immune system.BACKGROUND OF THE INVENTION[0002]Human milk fed infants have a lower incidence of infections, including viral infections, than formula fed infants. Many components in human milk, including immunoglobulins (such as IgA), interleukin (IL)-1, IL-6, IL-8, IL-10, interferon-γ (IFN-γ), immunocompetent cells, transforming growth factor-13 (TGF-13), lactoferrin, nucleotides, and non-digestible oligosaccharides (NDO) are thought to be involved in protection against infection with enteric or respiratory pathogens. TGF-β and dietary nucleotides were found to be components which may be responsible for increase in natural killer cell activity.[0003]NDO are a major constituent of human milk and are a major element of the innate immune system of human milk. Human NDO promote the growth of a beneficial microbiota domin...
