AL MENT TO ENHANCE IMMUNE SYSTEM OF AN INFANT
FIELD OF THE INVENTION
The present invention relates generally to a composition stered to a mother who is
breast-feeding her infant for enhancing an immune system and/or preventing an immune
system related disorder in the infant.
BACKGROUND TO THE INVENTION
During the first weeks or months of life, a number of external factors may influence the
infant’s growth and development. In particular, on-going research is making it more and
more apparent that the diet of the mother while breast-feeding her infant can affect the
infant’s health, both immediately and later in life.
It is therefore ble to provide maternal supplements which assist the mother in
providing her child with health benefits, including immune-related benefits such as a
se in allergic ons, including long-term benefits to the infant later in life when
the infant is no longer breast-fed.
The discussion of documents, acts, materials, devices, articles and the like is included in

supplementation with a non-digestible oligosaccharide while an offspring is receiving
breast milk has a beneficial mming effect on the immune response of the offspring.
Hence, the present invention relates to a maternal composition for a lactating rtum
female, the composition comprising a gestible oligosaccharide for enhancing the
immune system of an infant being breast-fed by the female. This composition can be
advantageously used for the enhancement of the immune system in the infant wherein the
composition is administered to the mother of the infant during lactation postpartum and the
advantageous effect in the infant can be observed later in life, e.g. during ood and/or
adolescence. The enhancement of the immune system may include an ement (e.g.
a decrease) in an allergic reaction.
Thus, according to a first aspect, the present invention es a composition comprising
a non-digestible oligosaccharide for use in enhancing an immune system of a mammalian
subject, wherein the composition is for administration to a lactating postpartum female who
is breast-feeding the mammalian subject.

offspring.
The term “comprising” and its ations is used in its non-limiting sense to mean that
items following the word are included, but items not specifically mentioned are not excluded.
Accordingly, the term "comprising" encompasses the more restrictive terms "consisting
essentially of" and "consisting of."
The phrase e of ylation” (also referred to as DE or “degree of fication”)
is intended to mean the extent to which free carboxylic acid groups been fied (e.g. by
methylation). For example, with nce to pectin, the phrase “degree of ylation”
or “DE” or “degree of fication” refers to the extent to which free carboxylic acid groups
contained in the polygalacturonic acid chain have been esterified (e.g. by methylation).
The phrase “enhancing the immune system of a mammalian subject” (and similar) is
generally defined as providing or causing a beneficial improvement in the immune system
of the mammalian subject, including but not limited to strengthening, improving, and/or
ating the immune system of the mammalian subject. The thening, improvement,
and/or stimulation may be with respect to a control group, which may be with respect to a
mammalian subject whose mother did not ingest the composition comprising the non-
digestible oligosaccharide described herein during lactation.
To enhance an immune system, as is well-known in the art, means to at least increase a
mammalian subject’s capacity to respond to n or disease-specific ns, i.e., those
cells primed to attack such antigens are increased in number, activity and ability to detect
and destroy antigens. In some other suitable embodiments, the enhancement of an
immune system refers to preventing, protecting against and/or decreasing an unwanted
immune response. Immune response may be measured by any number of standard tests
known in the art, including tests performed in vitro on a sample collected from a
mammalian subject. Enhanced immune response may also be ted by a change
(increase or decrease) of physical manifestations such as fever and inflammation, as well
as healing of systemic and local infections, reduction in symptoms in disease and the like.
An illustrative example of an enhanced immune system includes an improved allergic
response in the mammalian subject. Accordingly, in some specific embodiments, the
t invention aims to improve the allergic response in the mammalian subject or a
related disease including but not d to atopic dermatitis, asthma, occupational asthma,
food allergy ding cow’s milk allergy and others), allergic rhinitis (e.g. pollen allergy),
dust mite y and other forms of hypersensitivity like systemic anaphylaxis and acute
ria.
The phrase “immune system related disorder” as used herein refers to unwanted,
undesirable and/or excessive immune system reactions, including unwanted, undesirable
or excessive allergic reactions, autoimmune conditions, and the like. These reactions may
be caused in part or in total by over stimulation of the immune system that may lead to
excessive inflammation and/or destruction of normal cells and/or tissues. Immune system
related disorder(s) may be damaging, uncomfortable, and/or occasionally fatal. Non-limiting
examples of disorders may include y Type 1, y Type 2, allergy Type 3, allergy
Type 4, eczema, asthma, rhinitis, hay fever, rhino-conjunctivitis, wheezing, intestinal
infections, respiratory infections, atopic dermatitis, allergic dermatitis, food allergy and the
like.
The term “lactating” refers to both the act of secreting milk from the mammary glands and
the period of time that a female breast-feeds its offspring. In human beings, the terms
“breast-feeding a! u
, g” and “lactating” may be interchangeably used.
The term “non-digestible” as used in herein refers to saccharides and/or oligosaccharides
which are not digested in the intestine by the action of acids or digestive enzymes t
in the human upper digestive tract (small intestine and stomach), but which are fermented
by the human intestinal flora.
The term partum” is herein defined to be the period beginning immediately after the
birth of a child. Postpartum refers to the mother.
The phrase nting an immune system related disorder” (and the like) is herein defined
to be a prophylactic treatment of a mammalian subject in need thereof, including but not
limited to preventing, ing, altering, reversing, affecting, inhibiting the development or
progression of, ameliorating, or curing (1) an immune system related disorder, or (2) a
m of an immune system related disorder, or (3) a predisposition toward an immune
system related disorder, including conferring protective immunity on the mammalian subject.

The term “soluble” as used herein with reference to a gestible oligosaccharide means
that the nce is soluble according to the method described by L. Prosky et al, 1988.
The term “mammalian subject” is herein defined as a mammalian individual, suitably a
human. For purposes of research, the subject may be a non-human. For example the
subject may be an animal suitable for use in an animal model, e.g., a pig, horse, mouse, rat,
cow, dog, cat, cattle, non-human primate (e.g. chimpanzee) and the like.
Maternal Compositions
According to a first , the present invention provides a composition comprising,
consisting of, or consisting substantially of a non-digestible oligosaccharide for use in
enhancing an immune system of a mammalian subject, wherein the composition is for
administration to a lactating, postpartum female who is breast-feeding the mammalian
subject.
According to further aspect, the present invention provides a use of a non-digestible
accharide for the preparation of a composition for enhancing an immune system
and/or preventing an immune system related disorder in a mammalian subject, wherein the
composition is for administration to a lactating and postpartum female who is breast-
g the mammalian subject.
According to another aspect, the present invention es a method of enhancing and/or
preventing an immune system d disorder in a mammalian subject, the method
comprising providing or administering a composition comprising a non-digestible
oligosaccharide to a lactating and postpartum female who is breast-feeding the mammalian
subject.
According to yet another aspect, the present invention provides a method of providing or
administering a ition sing a non-digestible oligosaccharide to a lactating,
postpartum female who is breast-feeding a mammalian subject, wherein the composition
es an immune system and/or prevents an immune system related disorder in the
mammalian subject.
For the purposes of the present invention, the oligosaccharide may be selected from the
group consisting of galacto-oligosaccharides, fructo-oligosaccharides and acidic
oligosaccharides. ly, the accharides used according to any aspect of the

present ion may comprise, consists of, or consists substantially of galactooligosaccharide
, fructo-oligosaccharide and acidic oligosaccharide.
Suitably, the galacto-oligosaccharide is a shortchain-galacto-oligosaccharide and/or the
fructo-oligosaccharide is a longchain-fructo-oligosaccharide. Advantageously, a
mammalian subject whose mother receives the non-digestible oligosaccharides during
postpartum lactation (e.g. while breast-feeding the mammalian subject) may have a
significantly reduced allergic response (e.g. undesirable allergic response) as compared to
a mammalian subject whose mother did not receive the non-digestible accharide
during postpartum lactation (e.g. while breast-feeding the mammalian subject). Suitably,
the mammalian subject is a human.
Non-digestible oligosaccharides
The non-digestible oligosaccharide may be a prebiotic oligosaccharide. These non-
digestible oligosaccharides may beneficially affect the host by selectively ating the
growth and/or ty of one or a limited number of bacterial species in the colon.
ly, the present gestible oligosaccharide may be soluble. Soluble
oligosaccharide allow for ease of use and easy absorption into the body of the .
The accharide may be a neutral oligosaccharide or an acidic oligosaccharide.
Neutral non-digestible accharides
The phrase “neutral oligosaccharides” as used in the present invention refers to
saccharides which have a degree of polymerisation of monose units exceeding 2, more
suitably exceeding 3, even more suitably exceeding 4, most suitably exceeding 10, which
are not or only partially digested in the intestine by the action of acids or digestive enzymes
present in the human upper digestive tract (small ine and stomach) but which are
fermented by the human intestinal flora and ably lack acidic groups. The neutral
oligosaccharide may be structurally (chemically) different from an acid oligosaccharide.
The term neutral oligosaccharides as used in the present invention refers to saccharides
which have a degree of polymerisation of the oligosaccharide below 100 monose units,
suitably below 50, even more suitably below 25, most suitably below 10.
The term “monose units” refers to units having a closed ring structure, preferably ,
e.g. the pyranose or furanose forms.
The neutral accharide may comprise at least 90%, more ly at least 95%
monose units selected from the group consisting of mannose, arabinose, fructose, fucose,
rhamnose, galactose, B-D-galactopyranose, ribose, glucose, xylose and derivatives thereof,
calculated on the total number of monose units contained therein.

Applications
The present composition may be advantageously used to enhance an immune system,
including an improved allergic response.
In some embodiments, the enhanced immune system comprises an ed allergic
response in the mammalian t. In exemplary embodiments, the immune system
related disorder is a disorder or disease related to an allergic se including but not
limited to atopic dermatitis, asthma, occupational , food y (including hen’s egg
allergy, cow’s milk allergy and others), allergic rhinitis (e.g. pollen y), dust mite allergy
and other forms of hypersensitivity like systemic anaphylaxis and acute urticaria.
In some ments, the compositions described herein can be used to enhance an
immune response and/or prevent an immune system related disorder in the mammalian
subject, wherein at least the mother of the mammalian subject has an immune system
related disorder. Thus in some embodiments, the female suffers from an immune system
related er, or suffered from an immune system related disorder earlier in her life (e.g.
during infancy or childhood).
The present invention is based on the discovery that administration of a composition
comprising a non-digestible acidic-oligosaccharide as described herein to a female breast-
feeding an infant has a long-term impact on the development and enhancement of the
immune system in the infant.
The inventors have recognised this cted erm effect on the immune response.
Accordingly, in some embodiments the present invention aims to enhance the immune
system (or immune response) and/or prevent an immune system d disorder of a
mammalian subject (e.g. a human infant), where such enhancement or prevention effect
occurs in the mammalian subject at a time when the composition is no longer administered
to the mother of the mammalian subject (e.g. the mammalian subject has been born or is
no longer breast-feeding, for example a human infant who has weaned or is an adolescent),
suitably exceeding the age by at least one year, suitably by 2 years, suitably by 3 years,
more suitably by 5 years, most suitably by 8 years.
Thus in some exemplary embodiments, the itions described herein may enhance
the immune response and/or prevent an immune system related disorder later in life in the
mammalian subject (e.g. human subject). With “later in life” is meant an age exceeding the
age at which the mammalian subject is breast-fed, suitably exceeding the age by at least
12 months, more suitably by 24 , by 36 months, by 5 years, most suitably by 8 years.
Having now generally described the invention, the same will be more readily understood
through reference to the ing examples which are provided by way of illustration, and
are not intended to be limiting of the t invention.
A person skilled in the art will iate that the present invention may be practised
without undue experimentation according to the method given herein. The methods,
techniques and chemicals are as described in the references given or from standard
protocols.
EXAMPLES
Example 1: Maternal supplementation with non-digestible accharides
Materials & Methods
Chemicals
min (Grade V) was obtained from Sigma (St. Louis, USA). Cholera toxin was
sed from Quadratech Diagnostics. Phosphate ed saline (PBS) was obtained
from BioWhittaker (Verviers, Belgium).
Animals
3 week old female CBH/HeOuJ mice were obtained from Charles River (France) and
housed at constant temperature (20°C) and humidity (40-60%) at a 12:12 hour light/dark
cycle in the animal facility of Utrecht University. Animal care and use were med in
accordance with the guidelines of the Dutch Committee of Animal Experiments and the
local university ethical committee.
Experimental setup
Female mice were sensitised astric (i.g.) once a week for five weeks with hen’s egg
ovalbumin (OVA) (20 ug/500ul PBS) using cholera toxin (CT) (10 ug/500ul PBS) as
adjuvant. Control groups received either phosphate-buffered saline (PBS) or PBS + CT.
Two weeks after the last sensitisation mice were mated and fed either a control diet (AIN93)
or the A|N93 diet supplemented with a specific non-digestible oligosaccharide mixture
containing shortchain-galacto-, longchain-fructo- and pectin-derived acidic-oligosaccharides
(1%, ratio 9:1 :2) (GFA) during pregnancy or ion (Table 1).

Table 1. Description of the 9 groups of mice
After weaning, all female offspring were transferred to the control diet and sensitised orally
once a week for four weeks with OVA + CT. One week after the last sensitisation, the
offspring were challenged ermally with 20pg ul PBS in the ear, with the
exception of animals in group 1, which received PBS intradermally. Individual shock scores
were assessed 30 minutes after intradermal challenge. In addition, the temperature of the
mice was measured 1 minute before intradermal challenge, and every 15 minutes after
challenge until the ear swelling (as a measure of the acute allergic skin response to OVA)
was measured after one hour. Ear thickness was measured in duplicate before antigen
challenge and 1 hour aftenNards using a digital micrometer (Mitutoyo Digimatic 293561;
Veenendaal, The Netherlands). The acute allergic skin response was calculated by
subtracting the basal ear thickness from the value at 1 hour after challenge (A ear
thickness), and values are given as AuM. imately 6 hours after the intradermal
challenge, mice were nged orally with OVA (100 mg/500ul). 18 hours after the oral
challenge, mice were iced and samples were collected for eX-vivo analyses.
Plasma Antibody Concentrations
OVA-specific immunoglobulins were measured as described previously (Deurloo et al.).
Values are given as arbitrary units (A.U.) as the standard curve was prepared from the
pooled samples of all the animals in the ment.
Results
Acute allergic skin response
The acute ic skin response in the offspring of OVA-sensitised dams supplemented
with the non-digestible oligosaccharides (scGOS/lcFOS/pAOS) during pregnancy or
lactation was significantly (p < 0.05) reduced compared to offspring of OVA-sensitized mice
fed the control diet during pregnancy or lactation (Figure 1). This effect was ed for
both the offspring of OVA-sensitised dams supplemented during pregnancy as well as
lactation. In contrast to these results, supplementation did not icantly attenuate the
acute allergic skin response in the offspring of the non-sensitised dams (i.e. those who
received PBS or PBS + CT prior to mating) (Figure 1).
Shock scores and temperature
Shock scores as a result of the ermal challenge with OVA were icantly higher in
groups 2—7 when compared to the sham-challenged mice in group 1. The shock scores of
mice from groups 8 and 9 did not differ significantly from the sham-challenged mice (Figure
2). This observation is in line with the results from the acute allergic skin response.
However, as g shock symptoms may be at subjective, the temperature of the
mice was also measured (Figure 3). A decrease in temperature after intradermal challenge
is a quantifiable shock symptom as a result of acute allergic response to OVA. Compared
to the sham-challenged mice in group one, there was a significant decrease in temperature
minutes after intradermal challenge with OVA in groups 2, 3, 4 and 5. In groups 6-9,
there was no significant decrease in temperature as compared to the sham-challenged
animals.
OVA-specific immunoglobulins
When comparing the OVA-specific lgE levels in offspring of OVA-sensitised, supplemented
dams (group 8 and 9) to sensitised, non-supplemented dams (group 7), a decrease in
ecific lgE levels was only ed in the offspring of dams supplemented during
lactation (Figure 4A). Similarly, no significant difference in OVA-specific lgE levels was
observed between the offspring of pplemented PBS-treated dams (group 2) and
WO 17235
those supplemented during pregnancy (group 3) (Figure 4A). In contrast, a significant
decrease in OVA-specific lgE was observed both in offspring of CT-treated dams
mented during pregnancy (group 5), and those supplemented during lactation (group
6) when ed to the offspring of pplemented dams (group 4) (Figure 4A). OVA-
specific lgE levels in group 1 were only significantly different compared to group 4, r,
as these mice were not challenged with OVA at the end of the experiment they cannot be
compared to the other groups (data not shown).
OVA-specific lgG1 levels differed icantly between group 4 and 6, and group 7 and 9,
indicating that supplementation during ion can affect the production of this Th2—related
immunoglobulin in the offspring regardless of the treatment of the dams (Figure 4B)
OVA-specific lgG2a levels were significantly higher in the offspring of CT-treated and
OVA+CT-treated dams supplemented during pregnancy or ion when compared to
offspring of non-supplemented dams. This effect was not observed in offspring of PBS-
treated dams (Figure 4C).
The results in Example 1 suggest that maternal supplementation with non-digestible
carbohydrates has a cial programming effect on the immune response of offspring.
