Abstract
Dictyophora indusiata, an edible mushroom, is widely used not only as health foods but also as traditional Chinese medicine. This study aimed to investigate the molecular mechanism involved in the immunostimulatory activity of a polysaccharide from Dictyophora indusiata (DIP) in RAW264.7 cells. Results indicated that DIP induced the up-regulation of nitric oxide (NO), interleukin-1β (IL-1β), interleukin-6 (IL-6) and tumour necrosis factor (TNF-α) production as well as the mRNA expression levels of iNOS, IL-1β, IL-6 and TNF-α in macrophages. Furthermore, the functional blocking antibodies against TLR4 could markedly suppress DIP-mediated NO, IL-1β, IL-6 and TNF-α production. Flow cytometry and confocal laser-scanning microscopy analyses confirmed that DIP could bind specifically to target cells, and the binding could be inhibited by anti-TLR4 monoclonal antibodies. The expression of nuclear factor kappa B (NF-κB) p65 was significantly induced by DIP. Therefore, the DIP-induced macrophage activation may be mediated via the TLR4/NF-κB signalling pathway.

Abstract
The antitumor activity of cytokine-induced killer (CIK) cells can be increased by co-culturing them with tumor lysate-pulsed dendritic cells (tDCs); this phenomenon has been studied mainly at the population level. Using time-lapse imaging, we examined how CIK cells gather information from tDCs at the single-cell level. tDCs highly expressed CCL5, which bound CCR5 expressed on CIK cells. tDCs strongly induced migration of Ccr5(+/+) CIK cells, but not that of Ccr5(-/-) CIK cells or Ccr5(+/+) CIK cells treated with the CCR5 antagonist Maraviroc. Individual tDCs contacted Ccr5(+/+) CIK cells more frequently and lengthily than with Ccr5(-/-) CIK cells. Consequently, tDCs increased the antitumor activity of Ccr5(+/+) CIK cells in vitro and in vivo, but did not increase that of Ccr5(-/-) CIK cells. Taken together, our data provide insight into the mechanism of CIK cell activation by tDCs at the single-cell level.

Abstract
In this study, we evaluated the immunomodulatory activity of an exopolysaccharide (EPS) derived from Trichoderma pseudokoningii and investigated the molecular mechanism of EPS-mediated activation of macrophages. Results revealed that EPS could significantly induce the production of nitric oxide (NO), tumor necrosis factor (TNF)-α and interleukin (IL)-1β and enhance phagocytic activity in RAW 264.7 cells. Immunofluorescence staining indicated that EPS promoted the nuclear translocation of nuclear factor (NF)-κB p65 subunit. Western blot analysis showed that EPS increased the expression of inducible nitric oxide synthase (iNOS) protein, the degradation of IκB-α and the phosphorylation of mitogen-activated protein kinases (MAPKs). Furthermore, pretreatment of RAW 264.7 cells with specific inhibitors of NF-κB and MAPKs significantly attenuated EPS-induced TNF-α and IL-1β production. EPS also induced the inhibition of cytokine secretion by special antibodies against Toll-like receptor-4 (TLR4) and Dectin-1. These data suggest that EPS from Trichoderma pseudokoningii activates RAW 264.7 cells through NF-κB and MAPKs signaling pathways via TLR4 and Dectin-1.

Abstract
To discuss the molecular mechanism of immunoenhancing activities of Hyriopsis cumingii polysaccharides (HCPS), effects of HCPS on mice immunologic receptors (toll-like receptors-4 [TLR-4] and mannose receptor-1 [MR-1]), transcription factor (nuclear factor kappa-B [NF-κB]), and cytokines (interleukin-6 [IL-6] and tumor necrosis factor-α [TNF-α]) were evaluated by cell model in vitro and cyclophosphamide-induced immunosuppression animal model in vivo. Results showed that HCPS could promote the mRNA synthesis of TLR-4, MR-1, IL-6, and TNF-α in spleen, and the gene expression of TLR-4, MR-1, NF-κB, IL-6, and TNF-α in spleen and serum in a dose-dependent manner. Crude HCPS and its purified fractions (HCPS-1, HCPS-2, and HCPS-3) could strengthen peritoneal macrophage expressing MR-1 and NF-κB in a dose-dependent manner. In addition, HCPS-3 showed stronger promotions on MR-1 and NF-κB than crude HCPS, HCPS-1, and HCPS-2. It suggested that HCPS-stimulated immunostrengthening was mediated, at least in part, by TLR-4/NF-κB/IL-6 and TLR-4/NF-κB/ TNF-α signaling pathways. MR-1, IL-6, and TNF-α might be 3 of the immune regulators mediating immunity and homeostasis when HCPS performed immunoenhancing activities.

Abstract
In this work, a novel water-soluble homogeneous polysaccharide (LJP-31) with a molecular mass of 2.24 × 10(6) Da was isolated and purified from Laminaria japonica using DEAE-cellulose and Sephacryl S500 chromatography. Results showed that LJP-31 mainly consists of arabinose, mannose, glucose and galactose in a molar ratio of 1.0:7.8:6.6:0.8. LJP-31 exhibited significant stimulation on macrophages and enhanced the production of NO, TNF-α, IL-1β, IL-6 and IL-10 as well as the up-regulation of their gene expressions. Western blot analysis suggested that LJP-31 has the positive effects on the translocation of NF-κB p65 from cytoplasm to nucleus and the phosphorylation of IκBα, ERK1/2, JNK1/2 and P38 in macrophages. Flow cytometric and confocal laser-scanning microscopy analysis indicated that toll-like receptor 4 (TLR4) was at least one of the recognition receptors of LJP-31 on the plasma membrane of macrophages. Taken together, LJP-31 may exert its immunostimulating potency via TLR4 activation of MAPK and NF-κB signaling pathways.

Abstract
In the present study, a new water-soluble polysaccharide (LJP-11) was obtained from Laminaria japonica by anion exchange DEAE-cellulose chromatography and Sephacryl S-500 chromatography. The average molecular weight of this polysaccharide was estimated to be about 2.89×10(6) Da by high performance liquid chromatography system. Gas chromatography showed that LJP-11 was composed of arabinose, mannose and glucose in a molar ratio of 1.0:1.16:6.33. LJP-11 contains a long backbone consisting of (1→4)-β-D-GlcpAc, (1→4)-α-D-Glcp, (1→6)-β-D-Glcp and (1→3,6)-α-D-Manp. The 1-linked β-L-Araf was linked to the C-6 of (1→3)-α-D-Manp and the sulfate group was attached to the C-4 of (1→6)-β-D-Glcp. Pharmacological tests displayed that LJP-11 can stimulate macrophages to release NO, IL-6, TNF-α and IL-10 as well as the up-regulation of their gene expressions, indicating LJP-11 has beneficial effects on immunostimulation. Moreover, LJP-11 exhibited positive effects on the translocation of NF-κB p65 from cytoplasm to nucleus and the phosphorylation of IκBα, ERK1/2, JNK1/2 and P38 in macrophages. These results suggested that the activation of MAPK and NF-κB signaling pathways is one of the mechanisms responsible for the immunostimulating activity of LJP-11.

Abstract
The aim of this study was to investigate the molecular mechanism underlying the immunomodulatory effect of Ganoderma atrum polysaccharide (PSG-1) in spleen lymphocytes. Our results showed that PSG-1 increased the intracellular Ca2+ concentration and calcineurin (CaN) activity. Moreover, PSG-1 was found to elevate nuclear factor of activated T cells (NFAT) activity, but this effect could be diminished by the treatment of CaN inhibitors (cyclosporin A and FK506). PSG-1-induced interleukin (IL)-2 production was also inhibited by cyclosporin A and FK506. In addition, PSG-1 was found to significantly enhance protein kinase C (PKC) activity. PKC was involved in induction of NFAT activity by PSG-1, as evidenced by abrogation of NFAT activity by PKC inhibitor calphostin C, which significantly decreased PSG-1-induced IL-2 production. On the basis of these results, we concluded that PSG-1 may induce activation of spleen lymphocytes at least in part via the Ca2+/CaN/NFAT/IL-2 signaling pathway and the PKC/NFAT/IL-2 signaling pathway cooperatively regulated PSG-1-induced activation of spleen lymphocytes.

Abstract
Bengkoang (Pachyrhizus erosus (L.) Urban) is an edible root tuber containing fairly large amounts of carbohydrates and crude fibers. Our previous studies showed that the bengkoang fiber extract (BFE) stimulates activation of macrophages, leading to induction of phagocytotic activity and cytokine production. In the present study we investigated the mechanism underlying activation of murine macrophages by BFE. BFE increased production of TNF-α, IL-6, and nitric oxide by J774.1 cells. In addition BFE also facilitated the gene expression levels of inducible nitric oxide synthase. We examined the effect of a TLR4 inhibitor on cytokine production to investigate the membrane receptor of macrophage activation by BFE. Treatment of J774.1 cells with the TLR4 inhibitor significantly inhibited production of IL-6 and TNF-α, suggesting that TLR4 is the target membrane receptor for BFE. The main signal molecules located downstream of TLR4 such as JNK, p38, ERK, and NF-κB were activated by BFE treatment. The immunostimulatory effect of BFE was cancelled by the pectinase treatment, suggesting that the active ingredient in BFE is pectin-like molecules. Overall results suggested that BFE activates J774.1 cells via the MAPK and NF-κB signaling pathways.

Abstract
The aim of this study is to investigate the role of Toll-like receptor (TLR) 4 in Ganoderma atrum polysaccharide (PSG-1)-induced antitumor activity. In vitro, the apoptosis rate of S-180 cells was increased in PSG-1-induced peritoneal macrophage derived from C3H/HeN (wild-type) mice, but not from C3H/HeJ (TLR4-deficient) mice. In the S-180 tumor model, phagocytosis, NO and ROS release, phosphorylation of MAPKs and Akt, and expression of NF-κB were increased by PSG-1 in peritoneal macrophage derived from C3H/HeN mice. Furthermore, PSG-1 elevated Th1 cytokine production and enhanced the cytotoxic activity of CTL and NK cells in C3H/HeN mice. In addition, PSG-1 decreased the tumor weight and increased the apoptosis rate and caspase-3 and caspase-9 activities of tumor derived from the C3H/HeN mice. However, none of these activities were observed in C3H/HeJ mice. In summary, these findings demonstrated that the antitumor activity of PSG-1 is mediated by TLR4.

Abstract
A new water-soluble polysaccharide (longan polysaccharide 1 (LP1)) was extracted and successfully purified from Dimocarpus longan pulp via diethylaminoethyl (DEAE)-cellulose anion-exchange and Sephacryl S-300 HR gel chromatography. The chemical structure was determined using Infrared (IR), gas chromatography (GC) and nuclear magnetic resonance (NMR) analysis. The results indicated that the molecular weight of the sample was 1.1 × 10(5) Da. Monosaccharide composition analysis revealed that LP1 was composed of Glc, GalA, Ara and Gal in a molar ratio of 5.39:1.04:0.74:0.21. Structural analysis indicated that LP1 consisted of a backbone of → 4)-α-D-Glcp-(1 → 4)-α-D-GALPA-(1 → 4)-α-D-Glcp-(1 → 4)-β-D-Glcp-(1 → units with poly saccharide side chains composed of → 2)-β-D-Fruf-(1 → 2)-L-sorbose-(1 → attached to the O-6 position of the α-D-Glcp residues. In vitro experiments indicated that LP1 had significantly high antitumor activity against SKOV3 and HO8910 tumor cells, with inhibition percentages of 40% and 50%, respectively. In addition, LP1 significantly stimulated the production of the cytokine interferon-γ (IFN-γ), increased the activity of murine macrophages and enhanced B- and T-lymphocyte proliferation. The results of this study demonstrate that LP1 has potential applications as a natural antitumor agent with immunomodulatory activity.

Abstract
A water-soluble polysaccharide (OFPS11) was obtained from okra (Abelmoschus esculentus) flowers using aqueous extraction and purification with DEAE-52 cellulose and Sephacryl™ S-500 column. Its preliminary characterization and immunomodulating activity were investigated. Results showed that OFPS11 is mainly composed of galactose and rhamnose in a molar ratio of 2.23:1 with molecular mass of 1,700 kDa. RAW264.7 cells pretreated with OFPS11 significantly inhibited the proliferation of HepG-2 cells. Additionally, OFPS11 enhanced the phagocytic ability and induced the elevation of NO production, TNF-α and IL-1β secretion of RAW264.7 cells. Furthermore, OFPS11 promoted both the expression of iNOS protein and of iNOS and TNF-α mRNA. OFPS11 can strongly increase NF-κB levels in nucleuses, which is an important transcription factor that can modulate expressions of iNOS, NO and TNF-α. These outcomes support that OFPS11 exerts its antitumor activity by probably stimulating macrophage activities through nuclear NF-κB pathway.

Abstract
In this study, we employed a one-step method to prepare selenium nanoparticles (SeNPs) decorated by the water-soluble derivative of Ganoderma lucidum polysaccharides (SPS). The SeNPs-SPS complexes were stable, and the diameter of the SeNPs was homogeneous at around 25 nm. We investigated the anti-inflammatory activity of SeNPs-SPS against murine Raw 264.7 macrophage cells induced by LPS. SeNPs-SPS were found to significantly inhibit LPS-stimulated nitric oxide (NO) production against Raw 264.7 macrophages. RT-PCR results reveal the down-regulation of mRNA gene expressions for pro-inflammatory cytokines, including inducible NO synthase (iNOS), interleukin (IL)-1 and TNF-α in a dose-dependent manner. However, the anti-inflammation cytokine IL-10 was markedly increased. In the NF-κB signal pathway, SeNPs-SPS significantly inhibited the phosphorylation of Iκ-Bα. Similar results were observed for inhibition of the phosphorylation of JNK1/2 and p38 mitogen-activated protein kinase(MAPKs), whereas ERK1/2 MAPK was not apparently affected by SeNPs-SPS. All of these results suggest that SeNPs-SPS complexes have anti-inflammatory potential modulating pro-/anti-inflammation cytokine secretion profiles, and that the mechanism is partially due to inhibition of activations of NF-κB, JNK1/2 and p38 MAPKs.

Abstract
Recognition of the utility of the traditional Chinese medicine Lycium barbarum L. has been gradually increasing in Europe and the Americas. Many immunoregulation and antitumor effects of L. barbarum polysaccharides (LBP) have been reported, but its molecular mechanism is not yet clear. In this study, we reported that the activity of the polysaccharide LBPF4-OL, which was purified from LBP, is closely associated with the TLR4-MAPK signaling pathway. We found that LBPF4-OL can significantly induce TNF-α and IL-1β production in peritoneal macrophages isolated from wild-type (C3H/HeN) but not TLR4-deficient mice (C3H/HeJ). We also determined that the proliferation of LBPF4-OL-stimulated lymphocytes from C3H/HeJ mice is significantly weaker than that of lymphocytes from C3H/HeN mice. Furthermore, through a bio-layer interferometry assay, we found that LPS but not LBPF4-OL can directly associate with the TLR4/MD2 molecular complex. Flow cytometry analysis indicated that LBPF4-OL markedly upregulates TLR4/MD2 expression in both peritoneal macrophages and Raw264.7 cells. As its mechanism of action, LBPF4-OL increases the phosphorylation of p38-MAPK and inhibits the phosphorylation of JNK and ERK1/2, as was observed through Western blot analysis. These data suggest that the L. barbarum polysaccharide LBPF4-OL is a new Toll-like receptor 4/MD2-MAPK signaling pathway activator and inducer.

Abstract
Ganoderma atrum has been used as Chinese traditional medicine and healthful mushroom for thousands of years. The polysaccharide is regarded as the major bioactive substances in G. atrum. To delineate the underlying mechanism and signaling cascade involved in the immunomodulatory property of G. atrum polysaccharide (PSG-1). Specifically, this study is designed to examine the possibility of TLR4 as a candidate receptor interacted with G. atrum polysaccharide (PSG-1) and elucidate the role of reactive oxygen species (ROS) in PSG-1-induced tumor necrosis factor-α (TNF-α) production during macrophage activation. Flow cytometric and confocal laser-scanning microscopy analysis showed that fluorescence-labeled PSG-1 bind specifically to the macrophages. Moreover, PSG-1 stimulated TNF-α secretion of peritoneal macrophages from C3H/HeN mice, but not from C3H/HeJ mice. PSG-1-indcued TNF-α production was suppressed by anti-TLR4 mAb. Furthermore, ROS production was mediated by TLR4, and NADPH oxidase-derived ROS act as upstream of phosphoinositide 3-kinase(PI3K)/Akt/mitogen-activated protein kinases(MAPKs)/nuclear factor(NF)-κB signaling pathway in the regulation of PSG-1 stimulated TNF-α production. Taken together, we conclude that PSG-1 induces TNF-α secretion through TLR4/ROS/PI3K/Akt/MAPKs/NF-κB pathways during macrophage activation. Our findings provide a molecular basis for the potential of PSG-1 as a novel immunomodulatory agent.

Abstract
Schisandra chinensis (Turcz.) Baill has been used in traditional Chinese medicine for centuries. Previous studies have shown that Schisandra polysaccharide (SCPP11) has robust antitumor activity in vivo. In this study, the immunomodulatory activity and mechanisms of action of SCPP11 were investigated further to reveal its mechanism of action against tumors. Results showed that SCPP11 increased the thymus and spleen indices, pinocytic activity of peritoneal macrophages, and hemolysin formation in CTX-induced immunosuppressed mice. Moreover, SCPP11 significantly increased immunoglobulin levels, cytokines levels in vivo and induced RAW264.7 cells to secrete cytokines in vitro. RAW264.7 cells pretreated with SCPP11 significantly inhibited the proliferation of HepG-2 cells. In addition, SCPP11 promoted both the expression of iNOS protein and of iNOS and TNF-α mRNA. TLR-4 is a possible receptor for SCPP11-mediated macrophage activation. Therefore, the data suggest that SCPP11 exerted its antitumor activity by improving immune system functions through TLR-4-mediated up-regulation of NO and TNF-α.

Abstract
Gomisin A, one of the major dibenzocyclooctadiene lignans isolated from Schisandra chinensis Baill., has proved to possess a variety of pharmacological effects. The aim of the present study was to investigate the anti-inflammatory and neuroprotective effects of gomisin A as well as its potential molecular mechanisms. It was found that gomisin A not only inhibited the production of NO and PGE2 in a concentration-dependent manner but also suppressed the expressions of iNOS and COX-2 in LPS-stimulated N9 microglia without observable cytotoxicity. Gomisin A was also able to attenuate the mRNA expression and the production of pro-inflammatory factors TNF-α, IL-1β and IL-6. Moreover, LPS induced reactive oxygen species (ROS) production, NADPH oxidase activation, and gp91phox expression, which were markedly inhibited by gomisin A in microglia. Furthermore, the data showed that gomisin A significantly down-regulated the TLR4 protein expression, and inhibited nuclear transcription factor (NF)-κB and mitogen-activated protein kinases (MAPKs) signaling pathways. Additionally, gomisin A alleviated the cell death of SH-SY5Y neuroblastoma, rat primary cortical and hippocampal neurons induced by the conditioned-media from activated microglia. In summary, gomisin A may exert neuroprotective effects by attenuating the microglia-mediated neuroinflammatory response via inhibiting the TLR4-mediated NF-κB and MAPKs signaling pathways.

Abstract
A water-soluble low molecular weight polysaccharide (SCPP11) was extracted and purified using DEAE-cellulose and Sephadex G-100 column from Schisandra chinensis (Turcz.) Baill. Its in vivo and in vitro antitumor and immunomodulatory activity were investigated. The results showed that SCPP11 with a molecular weight of 3.4×10(3)Da exhibited indirect cyctotoxic activity against tumor cells in vitro, but could significantly inhibit the growth of Heps cells in vivo at dose of 50mg/kg, and its inhibition rate is higher than that in the positive group. Moreover, SCPP11 could ameliorate the hematological and biochemical parameters to almost normal and no significant changes in organ weight, and could increase the body weight. In addition, SCPP11 (at 50mg/kg) could also increased in thymus indexes as well as IL-2 and TNF-α levels in serum in vivo and significantly enhance the phagocytosis activity and the productions of NO of RAW264.7 in vitro. The results indicated that antitumor properties of SCPP11 might be achieved by improving immune response. It could be explored as a potential adjuvant against cancer used in the health food and pharmaceutical therapy.
