Abstract
Polysaccharides are macromolecules made up of many monosaccharides joinedtogether by glycosidic bonds. Polysaccharides from marine sources are widely distrib-uted as the principle component in cell wall structures of seaweeds or exoskeletonsof crustaceans. So far, marine polysaccharides have been used in many fields of bio-materials, food, cosmetic, and pharmacology. Especially, numerous pharmaceuticalproperties of marine polysaccharides have been revealed such as antioxidant, anti-inflammatory, antiallergic, antitumor, antiobesity, antidiabetes, anticoagulant,antiviral, immunomodulatory, cardioprotective, antihepatopathy, antiuropathy, andantirenalpathy activities. Recently, several marine polysaccharides such alginate,porphyran, fucoidan, and chitin and its derivatives have been found as modulatorsof allergic responses due to enhancing innate immune system, altering Th1/Th2

balance, inhibiting IgE production, and suppressing mast cell degranulation.

1. INTRODUCTION
Allergy is a disorder of the immune system due to an exaggerated reac-
tion of the immune system to harmless environmental substances, such as
animal dander, house dust mites, foods, pollen, insects, and chemical agents
(Milian & Dıaz, 2004). It can cause runny nose, sneezing, itching, rashes,
swelling, or asthma (Kay, 2000). It is noteworthy that the allergic diseases
are among the commonest causes of chronic ill-health. The prevalence,
severity, and complexity of these diseases are rapidly rising and considerably
adding to the burden of health-care costs (Kay, 2000). Substantially, allergic
reaction is characterized by the excessive activation of mast cells and baso-
phils by immunoglobulin E (IgE), resulting in an extreme inflammatory
response (Galli, Tsai, & Piliponsky, 2008). Acute allergic sensitization in
individuals is involved in the generation of allergen-specific CD4+ Th2 cells.
These cells secrete various cytokines, including IL-4, IL-5, IL-9, and IL-13,
as well as chemokines such as thymus, leading to further Th2 cell recruit-
ment and the production of allergen-specific IgE by B cells. Subsequently,
IgE circulates and binds surface receptors onmast cells and basophils. Further
exposure to allergen results in crosslinking of IgE on mast cells and basophils
causing cell degranulation, releasing histamine, proteases, chemokines, pros-
taglandins, leukotrienes, and a host of other mediators. This results in
bronchoconstriction and recruitment of activated eosinophils, neutrophils,
lymphocytes, and macrophages (Larche, 2007; Larche, Robinson, & Kay,
2003). These allergic cascades are considered as a source of molecular targets
for regulation of type I allergic reaction and management of allergic diseases.
Recently, the role of marine organisms-derived compounds as antiallergic
agents has been determined in vitro and in vivo by many researchers. Simul-
taneously, numerous marine compounds have been found to be efficient for
antiallergic therapeutics via modulation of Th1/Th2 balance, inhibition of
IgE production, and suppression of mast cell degranulation.
The world’s oceans, covering more than 70% of the earth’s surface, rep-
resent an enormous resource for the discovery of promising therapeutic
agents. Due to the unusual diversity of chemical structures, marine
2 Thanh-Sang Vo and Se-Kwon Kim
organisms have received much attention in screening marine natural prod-
ucts for their biomedical potential (Haefner, 2003; Molinski, Dalisay,
Lievens, & Saludes, 2009; Newman & Cragg, 2004). During the last
decades, marine organisms such as algae, tunicates, sponges, soft corals, bryo-
zoans, sea slugs, mollusks, echinoderms, fishes, microorganisms, etc., have
been subjected for isolation of numerous novel compounds. They have sig-
nificant amounts of lipid, protein, peptide, acid amine, polysaccharides,
chlorophyll, carotenoids, vitamins, minerals, and unique pigments (Blunt,
Copp, Munro, Northcote, & Prinsep, 2006; Faulkner, 2001, 2002). Nota-
bly, marine polysaccharides have been known as potential promising mate-
rials for a variety of uses in food, medicine, pharmaceutical, and nutraceutical
industries due to their biological properties and activities. This contribution,
therefore, focuses specially on the immunomodulatory effect of marine
polysaccharides and emphasizes their potential application as candidates of
pharmaceuticals as well as nutraceuticals to prevent allergic disorders.
2. MARINE POLYSACCHARIDES
Polysaccharides from marine sources offer diverse therapeutic func-
tions due to their biocompatible, biodegradable to harmless products, non-
toxic, and physiologically inert. Moreover, most of them are capable of
forming hydrogels because of their remarkable hydrophilicity, which helps
them to bind to proteins and other compounds. Several marine polysaccha-
rides such as alginate, porphyran, fucoidan, and chitin and its derivatives
have been found and extracted from various sources, especially seaweed
and crustacean. In recent years, numerous polysaccharides have been used
in many fields of biomaterials, food, cosmetic, and pharmacology.
2.1. AlginateAlginates are quite abundant in nature as structural component in marine
brown algae (Phaeophyceae) and as capsular polysaccharides in soil bacteria
(Laurienzo, 2010). The function of alginates in algae is primarily skeletal,
with the gel located in the cell wall and intercellular matrix conferring
the strength and flexibility necessary to withstand the force of water in which
the seaweed grows (D’Ayala, Malinconico, & Laurienzo, 2008). Alginate is a
linear, anionic block copolymer heteropolysaccharide consisting of β-D-mannuronic acid (M) and α-L-guluronic acid (G). The relative amount
and sequential distribution of homogeneous M–M segments (M-blocks),
homogeneous G–G segments (G-blocks), and alternating M–G segments
3Antiallergic Properties of Marine Polysaccharides
(MG-blocks), which represent the primary structure of alginate, depend on
the producing species, and for marine sources, on seasonal and geographical
variations (D’Ayala et al., 2008). Alginates may be prepared with a wide
range of average molecular weights (50–100,000 residues) to suit the appli-
cation. The process of the isolation of alginates from brown algae includes
the pre-extraction with hydrochloric acid, followed by washing, filtration,
and neutralization with alkali. Sodium alginate is precipitated from the solu-
tion by alcohol (isopropanol or ethanol) and usually reprecipitated in the
same way (Laurienzo, 2010). Over the last few years, medical and pharma-
ceutical industries have shown an increased interest in alginates due to effi-
cient treatment of esophageal reflux, creates multiquality calcium fibers for
dermatology, and wound healing. Alginate is an effective natural dis-
integrant, tablet binder and offers an attractive alternative for sustained-
release systems. It offers advantages over synthetic polymers as it forms
hydrogels under relatively mild pH and temperature and is generally reg-
arded as nontoxic, biocompatible, biodegradable, less expensive, and abun-
dantly available in nature. Accordingly, alginates are considered to be useful
materials for biomedical applications, especially for controlled delivery of
drugs and other biologically active compounds and for the encapsulation
of cells (D’Ayala et al., 2008).
2.2. PorphyranPorphyran is a sulfated polysaccharide isolated from seaweeds of order
Bangiales especially from the genera Porphyra. It is obtained from red algae
of KingdomRhodophyta. Chemically, porphyran is related to agarose, con-
sists of linear backbone of alternating 3-linked β-D-galactose and 4-linked
3,6-anhydro-α-L-galactose units. The L residues are mainly composed of
α-L-galactosyl 6-sulfate units, and the 3,6-anhydrogalactosyl units are minor.
Porphyran has been reported to possess various pharmaceutical properties
such as antioxidant, antitumor, immunostimulant, hypotensive, antifatigue,
antibacterial, anticoagulant, anticancer, antiviral, antihyperlipidemic, and
hepatoprotective activity (Bhatia et al., 2008).
2.3. FucoidansFucoidans are a complex series of sulfated polysaccharides found widely in
the cell walls of brown seaweeds. In recent years, different brown algae were
analyzed for their content of fucoidans. The low-molecular-weight fractions
of algal fucoidans (less than 30 kDa) obtained by depolymerization have
4 Thanh-Sang Vo and Se-Kwon Kim
been shown to exhibit some heparin-like properties, with less side effects
(Karim et al., 2011). Such polysaccharides do not occur in other divisions
of algae and in land plants. However, the related biopolymers were found
in marine invertebrates such as sea cucumbers or sea urchins. These polysac-
charides are simpler than fucoidans derived frommarine brown algae and are
referred to as sulfated fucans. The seaweed fucoidans are heterogenic and
represent the mixtures of structurally related polysaccharides with certain
variations of the content of carbohydrate units and noncarbohydrate substit-
uents (Cumashi et al., 2007). Fucoidans are mainly composed of fucose and
sulfate. Besides, they also contain other monosaccharides (mannose, galac-
tose, glucose, xylose, etc.) and uronic acids, even acetyl groups and protein.
The fucoidans of most algae consist of sulfated L-fucose with major fucose
components. However, some fucoidans have minor fucose components and
major other monosaccharides like galactose or uronic acids (Vo & Kim,
2013). According to Cumashi et al. (2007), the polysaccharide backbones
in fucoidans are known as type I or type II chains. The type I chains are
found to contain the repeating (1!3)-linked α-L-fucopyranose residues,
whereas type II chains contain the alternating (1!3)- and (1!4)-linked
α-L-fucopyranose residues. During the last decades, numerous pharmaceu-
tical properties of fucoidans have been revealed due to their antioxidant,
anti-inflammatory, antiallergic, antitumor, antiobesity, antidiabetes, antico-
agulant, antiviral, antihepatopathy, antiuropathy, and antirenalpathy effects
(Vo &Kim, 2013). These special properties of fucoidans have supported it to
be applied to functional foods for disease prevention and health promotion.
2.4. Chitin and its derivativesChitin is a linear polysaccharide consisting of β-(1–4)-N-acetyl
D-glucosamine residues. It is widely distributed in nature and is the second
most abundant polysaccharide in nature after cellulose. It may be regarded as
cellulose with hydroxyl at position C-2 replaced by an acetamino group.
Chitin is a white, hard, inelastic, nitrogenous polysaccharide found in the
cell walls of bacteria and fungi, mushrooms, exoskeleton of crustaceans
and insects, the microfilarial sheath of parasitic nematodes, and the lining
of the digestive tracts of many insect. These organisms use chitin to protect
the invader from the harsh conditions inside the animal or plant host (Elias,
Homer, Hamid, & Lee, 2005). Chitin is highly hydrophobic and it insoluble
in water and most organic solvents. It exists mainly in two forms including
α-chitin and β-chitin. α-Chitin consists of sheets of tightly packed
5Antiallergic Properties of Marine Polysaccharides
alternating parallel and antiparallel chains (Minke & Blackwell, 1978).
Meanwhile, β-chitin is arranged in parallel (Gardner & Blackwell, 1975),
which occurs less frequently in nature than α-chitin. Being nontoxic and
environmentally safe, chitin has become of great interest not only as a
utilized resource but also a new functional biomaterial of high potential
in many fields such as medical, agricultural, and cosmetic applications. It
is readily obtained for commercial use from crustacean shell waste products
generated by the seafood industry (Kumar, 2000; Kurita, 2006). Chitosan, a
partially deacetylated polymer of N-acetylglucosamine, is produced com-
mercially by deacetylation of chitin (Dutta, Dutta, & Tripathi, 2004).
During the past decades, chitosan has received considerable attention
due to its biodegradable, nontoxic, and nonallergenic properties, which
made it possible to be used in many fields including food, cosmetics, bio-
medicine, agriculture, and environmental protection (Kim & Rajapaksea,
2005). Recent studies have focused on the conversion of chitosan to
chitooligosaccharides (COS) since COS are not only water soluble and
possess higher oral absorption but also have various biological effects,
including antimicrobial, antitumor, anticancer, antioxidant, anti-
inflammatory, and antiangiotensin-I-converting enzyme activities
(Kim & Rajapaksea, 2005). Especially, chitin and its derivatives have been
determined to be protective agents against allergic diseases.
3. PHARMACOLOGICAL PROPERTIES OF MARINEPOLYSACCHARIDES FOR MODULATION OF ALLERGICRESPONSES
3.1. Alginic acidAlginic acid, a naturally occurring hydrophilic colloidal polysaccharide
obtained from the several species of brown seaweeds, exhibited different
effects against hyaluronidase activity and histamine release from mast cells
(Asada et al., 1997). In the in vivo conditions, alginic acid inhibited com-
pound 48/80-induced systemic anaphylaxis with doses of 0.25–1 g/kg
and significantly inhibited passive cutaneous anaphylaxis by 54.8% at
1 g/kg for 1 h pretreatment ( Jeong et al., 2006). Besides, alginic acid was
found to have a maximum suppression rate (60.8%) on histamine release
from rat peritoneal mast cells at concentration of 0.01 μg/ml. Furthermore,
the antiallergic activities of alginic acid were also observed due to its suppres-
sive effects on activity and expression of histidine decarboxylase, production
of IL-1β and TNF-α, and protein level of nuclear factor (NF)-κB/Rel A in
6 Thanh-Sang Vo and Se-Kwon Kim
PMA plus A23187-stimulated HMC-1 cells ( Jeong et al., 2006). Notice-
ably, alginic acid oligosaccharide (ALGO), a lyase lysate of alginic acid,
has been revealed to be able to reduce IgE production in the serum of
BALB/c mice immunized with β-lactoglobulin (Uno, Hattori, &
Yoshida, 2006; Yoshida, Hirano, Wada, Takahashi, & Hattori, 2004).
Moreover, antigen-induced Th2 development was blocked by ALGO treat-
ment via enhancing the production of IFN-γ and IL-12, and down-
regulating IL-4 production in splenocytes of mice (Yoshida et al., 2004).
3.2. PorphyranPorphyran, a sulfated polysaccharide isolated from red seaweeds, has been
recognized to be effective against different allergic responses. According to
Ishihara, Oyamada, Matsushima, Murata, and Muraoka (2005), porphyran
of red algae Porphyra tenera and P. yezoensiswere capable to inhibit the con-
tact hypersensitivity reaction induced by 2,4,6-trinitrochlorobenzene via
decreasing the serum level of IgE in Balb/c mice. Moreover, Yoshizawa
and colleagues have revealed that polysaccharide fractions from
P. yezoensis possessed the ability to activate macrophages in vitro and in vivo
via enhancing glucose consumption, the production of nitrite and tumor
necrosis factor (TNF), secretion of IL-1 from macrophages and carbon
clearance activity of phagocytes from mice injected intraperitoneally. It
has been indicated that porphyran is responsible for these effects and its sul-
fate group contributes to the macrophage stimulating activities (Yoshizawa
et al., 1995, Yoshizawa, Enomoto, Todoh, Ametani, & Kaminogawa,
1993). In addition, oral administration of porphyran from Porphyra
vietnamensis evoked a significant increase in weight of the thymus, spleen
and lymphoid organ cellularity, and total leucocyte and lymphocyte
(Bhatia et al., 2013).
3.3. FucoidansRecently, algal fucoidans have been found to be effective in suppression of
IgE and Th2 cytokine production in vitro and in vivo. Fucoidan fromUndaria
pinnatifida reduced the concentrations of both IL-4 and IL-13 in
bronchoalveolar lavage fluid (BALF) and inhibited the increase of
antigen-specific IgE in OVA-induced mouse airway hypersensitivity
(Maruyama, Tamauchi, Hashimoto, & Nakano, 2005). In the recent study,
Yanase et al. (2009) have reported that the peritoneal injection of fucoidan
caused an alleviative effect of plasma IgE level by suppressing a number of
7Antiallergic Properties of Marine Polysaccharides
IgE-expressing and IgE-secreting B cells fromOVA-sensitized mice. On the
other hand, the inhibitory effect of fucoidan on IgE production was deter-
mined due to preventing Cε germline transcription and NF-κB p52 trans-
location in B cells (Oomizu, Yanase, Suzuki, Kameyoshi, & Hide, 2006).
Yet, the inhibitory activity of fucoidan has been not observed if B cells were
prestimulated with IL-4 and anti-CD40 antibody before the administration
of fucoidan. Thus, it suggested that fucoidan may not prevent a further
increase of IgE in patients who have already developed allergic diseases
and high levels of serum IgE. However, Iwamoto et al. (2011) have recently
determined that fucoidan effectively reduced IgE production in both
peripheral blood mononuclear cells from atopic dermatitis patients and
healthy donors. These findings indicated that fucoidan suppresses IgE pro-
duction by inhibiting immunoglobulin class-switching to IgE in human
B cells, even after the onset of atopic dermatitis.
3.4. ChitinChitin has been evidenced as a potent innate immune stimulator of macro-
phages and other innate immune cells, and thus chitin is able to suppress
allergen-induced type 2 allergic responses. Indeed, Shibata and colleagues
have determined the immunological effects of chitin in vivo and in vitro using
phagocytosable small-sized chitin particles. It has shown that intravenous
administration of fractionated chitin particles into the lung activated alveolar
macrophages to express cytokines such as IL-12, TNF-α, and IL-18, leadingto INF-γ production mainly by NK cells (Shibata, Foster, Metzger, &
Myrvik, 1997). The production of cytokines induced by chitin is identified
to be mediated by a mannose receptor (Shibata, Metzger, & Myrvik, 1997).
In another study, Lee and colleagues have determined that chitin stimulates
macrophages by interacting with different cell surface receptors such as mac-
rophage mannose receptor, toll-like receptor-2, C-type lectin receptor
Dectin-1, and leukotriene 134 receptor (BLT1) (Lee, 2009). These studies
have shown the direct interactions between chitin and its cell surface recep-
tors and thus chitin regulates the specific signaling pathways in immune
responses.
In the further study of Shibata and colleagues, the suppressive effect of
Th2 responses has been confirmed when chitin was given orally in BALB/c
and C57BL/6 mice (Shibata, Foster, Bradfield, & Myrvik, 2000). It was
observed that chitin treatment resulted in decreases of serum IgE levels
and lung eosinophil numbers in both strains. The inhibitory mechanisms
8 Thanh-Sang Vo and Se-Kwon Kim
of Th2 responses by chitin was found due to decreases of Th2 cytokines
including IL-4, IL-5, and IL-10 levels and the production of Th1 cytokine
IFN-gamma in spleen cells isolated from the ragweed-immunized mice.
These results indicated that the immune responses were redirected toward
a Th1 response by chitin treatment, and thus downregulating Th2-facilitated
IgE production and lung eosinophilia in the allergic mouse. Moreover, the
Th1 adjuvant role of chitin has been determined via upregulating Th1
immunity induced by heat-killed Mycobacterium bovis and downregulating
Th2 immunity induced by mycobacterial protein (Shibata et al., 2001).
Likewise, Hamajima et al. (2003) has also reported the Th1 adjuvant effect
of chitin microparticles in inducing viral specific immunity.
Notably, the effectiveness of chitin microparticles when given intrana-
sally as a treatment for the symptoms of respiratory allergy and allergy asthma
has been tested in two different mouse models of allergy, namely to
Dermatophagoids pteronyssinus and Aspergillus fumigates (Strong, Clark, &
Reid, 2002). The intranasal application of microgram doses of chitin micro-
particles substantially reduced the allergen-induced serum IgE levels,
peripheral eosinophilia, airway hyperresponsiveness, and lung inflammation
in both allergy models. This effectiveness was found due to the increase
in Th1 cytokines IL-12, IFN-γ, and TNF-α and decrease in IL-4 produc-
tion during allergen challenge. The immunostimulatory properties of chitin
microparticles could offer a novel and natural approach to treating allergic
disease in humans.
3.5. Chitosan nanoparticlesIn the most recent study, chitosan nanoparticles have been determined as an
adjuvant agent via promoting immune response in ovalbumin (OVA)-
challenged mice (Wen, Xu, Zou, & Xu, 2011). Mice were immunized sub-
cutaneously with 25 μg OVA alone or with 25 μg OVA dissolved in saline
containing Quil A (10 μg), chitosan (50 μg), or chitosan nanoparticles (12.5,50, or 200 μg) on days 1 and 15. It was found that the serum OVA-specific
IgG, IgG1, IgG2a, and IgG2b antibody titers and Con A-, LPS-, and OVA-
induced splenocyte proliferation were significantly enhanced by chitosan
nanoparticles as compared with OVA and chitosan groups. Notably,
chitosan nanoparticles also significantly promoted the production of IL-2
and IFN-γ cytokines and upregulated the mRNA expression of IL-2,
IFN-γ cytokines in splenocytes from the immunized mice compared with
OVA and chitosan groups. Besides, chitosan nanoparticles remarkably
9Antiallergic Properties of Marine Polysaccharides
increased the killing activities of NK cells activity. The results suggested that
chitosan nanoparticles had a strong potential to increase both cellular and
humoral immune responses.
3.6. ChitooligosaccharidesIn the regard of COS on in vitro allergic responses, Vo, Kong, and Kim
(2011) and Vo, Kim, Ngo, Kong, and Kim (2012) have investigated the
inhibitory effect of COS on mast cell activation induced by calcium
ionophore A23187 or antigen. The pretreatment of COS causes signifi-
cant inhibition on mast cell degranulation via reducing histamine and
β-hexosaminidase release and intracellular Ca2+ elevation in RBL-2H3
mast cells. Moreover, the inhibitory effects of COS on expression as well
as production of various cytokines such as TNF-α, IL-1β, IL-4, and IL-6
were also evidenced. Notably, the protective effect of COS (<1 kDa)
against OVA-induced lung inflammation in asthma model mice was also
examined (Chung, Park, & Park, 2012). Oral administration of COS
(16 mg/kg body weight/day) resulted in a significant reduction in both
mRNA and protein levels of interleukin IL-4, IL-5, IL-13, and TNF-αin the lung tissue and BALF. The protein levels of IL-4, IL-13, and
TNF-α in BALF were decreased by 5.8-fold, 3.0-fold, and 9.9-fold,
respectively, compared to those in the OVA-sensitized/challenged asthma
control group. Collectively, these results indicate that COS can contribute
to attenuation of allergic reactions and might be a promising candidate for
novel inhibitor of allergic reaction.
4. CONCLUSION
Marine polysaccharides are considered as promising biomaterials that
are the focus of biomedical research today. Notably, many experimental
results clearly indicated that marine polysaccharides such as alginate,
porphyran, fucoidan, and chitin and its derivatives are exciting agents for
modulation of allergic responses via enhance of innate immune system, reg-
ulation of Th1/Th2 balance toward Th1 dominance, decrease in IgE pro-
duction, and inhibition of mast cell degranulation. Accordingly, marine
polysaccharides can be used as safety and efficacy biomaterials for the devel-
opment of food, pharmaceutical, and nutraceutical industries in prevention
and/or treatment of allergic disorders. The possibility of producing a variety
of chemically modified derivatives makes these polysaccharides versatile bio-
materials in almost all fields of biomedical interest.
