Zhang G, Guo F, Zeng M, Wang Z, Qin F, Chen J, Zheng Z, He Z. The immune-enhancing effect and in vitro antioxidant ability of different fractions separated from Colla corii asini. J Food Biochem 2022; 46:e14174. [PMID: 35415887 DOI: 10.1111/jfbc.14174] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2021] [Revised: 03/01/2022] [Accepted: 03/28/2022] [Indexed: 12/29/2022]
Abstract
In this study, Colla corii asini (CCA) was fractionated into three fractions with different molecular weights using ultracentrifugation equipment. Components with a molecular weight of >10 kDa in F1 accounted for 81.90%, whereas that in F2 and F3 was 15.63% and 0.94%, respectively. The immunomodulatory activity of CCA fractions was investigated using RAW264.7 cell model and their antioxidant abilities were evaluated by 2'-Azinobis-(3-ethylbenzthiazoline-6-sulphonate) (ABTS) and ferric-reducing antioxidant power (FRAP) assay. The results indicated that RAW264.7 cells treated with F1 released the highest level of nitric oxide, reactive oxygen species, interleukin-6, and tumor necrosis factor-α. The ABTS and FRAP value of F1 were 65.81% and 29.33 μM TE/L, respectively, which were 22.53%, 128.44% and 43.72%, 132.16% higher than that of F2 and F3, respectively. These results suggested that components with a molecular weight of >10 kDa in CCA had stronger immunomodulatory and antioxidant ability, which would help develop the health food based on CCA. PRACTICAL APPLICATIONS: Colla corii asini (CCA) is a famous protein-based traditional Chinese medicine and nutritional supplement. During the processing of CCA, the molecular weight (MW) of CCA collagen components changed dynamically due to the protein aggregation, degradation, and the Maillard reaction. Some studies have shown that the MW distribution of CCA was not uniform. However, the MW range of CCA components which has strong antioxidant and immunomodulatory activity is still not clear, and few studies have reported the mechanism of CCA's immunomodulatory activity and active ingredients. Therefore, it is important to figure out the characteristics of CCA components with stronger immunomodulatory and antioxidant ability, such as the MW distribution and chemical composition of CCA fractions. And this study will be great for the processing of CCA products which has better biological functions.

Abstract
The immune system comprises a complex group of processes that provide defense against diverse pathogens. These defenses can be divided into innate and adaptive immunity, in which specific immune components converge to limit infections. In addition to genetic factors, aging, lifestyle, and environmental factors can influence immune function, potentially affecting the susceptibility of the host to disease-causing agents. Chemical compounds in certain foods have been shown to regulate signal transduction and cell phenotypes, ultimately impacting pathophysiology. Research has shown that the consumption of specific functional foods can stimulate the activity of immune cells, providing protection against cancer, viruses, and bacteria. Here, we review a number of functional foods reported to strengthen immunity, including ginseng, mushrooms, chlorella, and probiotics (Lactobacillus plantarum). We also discuss the molecular mechanisms involved in regulating the activity of various types of immune cells. Identifying immune-enhancing functional foods and understanding their mechanisms of action will support new approaches to maintain proper health and combat immunological diseases. Evidence is building to support the idea that specific ‘functional foods’ can stimulate the activity of cells and signaling systems of the immune system to provide protection against cancer, viruses and bacteria. Sanguine Byun and colleagues at Yonsei University in Seoul, South Korea, review research into a range of functional foods, foods thought to have health benefits beyond their nutritional value. These include ginseng, mushrooms, the green algae called Chlorella and the probiotic bacteria Lactobacillus plantarum. They also consider individual components of foods such as poly-gamma-glutamate, a natural polymer made by bacteria. A wide body of research is revealing diverse molecular mechanisms through which biochemicals in functional foods can modulate different aspects of the immune system. These include effects on both non-specific innate immunity and adaptive immunity, which targets specific invading pathogens and diseased cells.

Abstract
We optimized the hot water extraction of polysaccharides from the root of Henry wood betony (RHWPs) using a uniform test and explored their anti-tumor activities in vitro and in vivo. The optimal extraction conditions were as follows: 40 min extraction time, liquid/solid ratio 30 mL/g, 100 min soaking time, two extraction cycles, 100% ethanol concentration, and extraction temperature of 80 °C. The molecular weight distribution of RHWPs with MWs was 228,600 g/mol and 5001 g/mol. The IR spectrum further indicated that RHWPs are acidic polysaccharides containing pyranose and furan rings. The main monosaccharides found in RHWPs were mannose, ribose, l-rhamnose monohydrate, glucuronic acid, galacturonic acid, glucose, galactose, xylose, arabinose, and fucose. RHWPs inhibited the proliferation of S180 tumor cells and induced apoptosis in vitro. Oral administration of RHWPs to tumor-bearing mice significantly inhibited the growth of the S180 xenografts, accelerated apoptosis in tumor cells, and expanded the necrotic regions. Furthermore, RHWPs also markedly increased the levels of TNF-α, IFN-γ, and IL-2 in the sera of tumor-bearing mice, and activated immune cells such as lymphocytes, NK cells, and macrophages, thereby inducing tumor cell apoptosis. Taken together, RHWPs are a promising anti-tumor agent that ought to be explored further.

JOURNAL OF ETHNOPHARMACOLOGY 2020; 263:113218. [PMID: 32755650 DOI: 10.1016/j.jep.2020.113218] [Citation(s) in RCA: 18] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/22/2020] [Revised: 07/21/2020] [Accepted: 07/28/2020] [Indexed: 06/11/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ginseng (Panax ginseng Meyer) is a very well-known traditional herbal medicine that has long been used to enhance the body's immunity. Because it is a type of ginseng, it is believed that wild simulated ginseng (WSG) also has immune-enhancing activity. However, study on the immune-enhancing activity of WSG is quite insufficient compared to ginseng. AIM OF THE STUDY In this study, we evaluated immune-enhancing activity of WSG through macrophage activation to provide a scientific basis for the immune enhancing activity of WSG. MATERIALS AND METHODS The effect of WSG on viability of RAW264.7 cells was evaluated by MTT assay. The NO level was measured by Griess reagent. The expression levels of mRNA or protein in WSG-treated RAW264.7 cells were analyzed by RT-PCR and Western blot, respectively. RESULTS WSG increased the production of immunomodulators such as NO, iNOS, COX-2, IL-1β, IL-6 and TNF-α and activated phagocytosis in mouse macrophages RAW264.7 cells. Inhibition of TLR2 and TLR4 reduced the production of immunomodulators induced by WSG. WSG activated MAPK, NF-κB and PI3K/AKT signaling pathways, and inhibition of such signaling activation blocked WSG-mediated production of immunomodulators. In addition, activation of MAPK, NF-κB and PI3K/AKT signaling pathways by WSG was reversed by TLR2 or TLR4 inhibition. CONCLUSION Based on the results of this study, WSG is thought to activate macrophages through the production of immunomodulators and phagocytosis activation through TLR2/4-dependent MAPK, NF-κB and PI3K/AKT signaling pathways. Therefore, it is thought that WSG have the potential to be used as an agent for enhancing immunity.

Abstract
The proper functioning of human immune system is essential for organism survival
against infectious, toxic and oncogenic agents. The present study aimed to describe the scientific evidence
regarding the immunomodulatory properties of the main micronutrients and specific phytochemicals.
Plants of food interest have the ability to dynamically affect the immune system through
particular molecules. Plant species, type of compounds and biological effects were herein reviewed
mainly focusing on plants which are not commonly used in food supplements. Several efficient phytoproducts
showed significant advantages compared to synthetic immunomodulators, being good
candidates for the development of immunotherapeutic drugs.

Abstract
BACKGROUND/AIM Although cisplatin is an effective anticancer drug, its toxic effects on normal tissues limit its use. We developed a herbal formula, MH-30, with increased fat-soluble polyphenols by improving the manufacturing method of HemoHIM. In this study, we examined whether the combination of MH-30 with cisplatin exerts synergistic antitumor effect while it reduces cisplatin-induced toxicities. MATERIALS AND METHODS MH-30 was produced by adding the ethanol-insoluble fraction to its extract after decocting herbs in 30% ethanol and water. We used a melanoma-bearing mice model to investigate synergistic anticancer effects. The NK cell activity and cytokine levels were measured by Cr51-release assay and ELISA. The AST, ALT, BUN, and creatinine levels were estimated in the serum. RESULTS MH-30 effectively inhibited melanoma growth in vitro. Furthermore, MH-30 had a synergistic effect in combination with cisplatin on melanoma growth inhibition in vitro and in vivo. In melanoma-bearing mice, cisplatin alone decreased the activity of NK cells and the levels of IL-2 and IFN-γ, which were effectively restored by the combination of MH-30 with cisplatin. Combined treatment with MH-30 and cisplatin significantly inhibited the cisplatin-induced increase in the levels of AST, ALT, BUN, and creatinine. CONCLUSION Combination of MH-30 with cisplatin may be a beneficial anticancer treatment with reduced adverse effects.

Abstract
Panax ginseng has long been used as natural medicine and health food all over the world. Cancer is a major cause of death worldwide and its prognosis likely depends on the immune system during tumor treatment. In this study, ginseng berry polysaccharides were evaluated for their immunostimulant and anti-cancer effects. Ginseng berry polysaccharide portion (GBPP) was used to investigate its effects on anti-complementary activity, peritoneal macrophage activation, and natural killer (NK) cell cytotoxicity. Moreover, both intravenous (i.v.) and oral administration of GBPP prior to B16-BL6 melanoma implantation in mice was evaluated. GBPP significantly increased the anti-complementary activity and cytokine production including interleukin (IL)-6, IL-12, and tumor necrosis factor (TNF)-α, dose-dependently. Splenocytes obtained after i.v. administration of GBPP showed cytolytic activity in Yac-1 cells in proportion to the E/T ratio. In addition, GBPP enhanced the production of interferon (IFN)-γ and granzyme B of NK cells. For the experimental lung cancer, compared with control mice, GBPP delivered by i.v. suppressed cancer by 48% at 100 μg/mouse, while a 37% reduction was achieved by oral administration. Deficient of NK cells in animal model demonstrated that the anti-cancer effect of GBPP was through NK cell activation. Results of this study suggest that ginseng berry polysaccharides, owing to their modulation of the immune response, can be a potential curative applicant for the prevention and treatment of tumors.

Abstract
A pregnant woman’s diet consists of many products, such as fruits, vegetables, cocoa, tea, chocolate, coffee, herbal and fruit teas, and various commercially available dietary supplements, which contain a high number of biological active plant-derived compounds. Generally, these compounds play beneficial roles in women’s health and the development of fetus health. There are, however, some authors who report that consuming excessive amounts of plants that contain high concentrations of polyphenols may negatively affect the development of the fetus and the offspring’s health. Important and problematic issues during pregnancy and lactation are bacterial infections treatment. In the treatment are proposals to use plant immunomodulators, which are generally considered safe for women and their offspring. Additional consumption of biologically active compounds from plants, however, may increase the risk of occurrences to irreversible changes in the offspring’s health. Therefore, it is necessary to carry out safety tests for immunomodulators before introducing them into a maternal diet. Here, we present data from animal experiments for the four most-studied plants immunomodulators genus: Rhodiola, Echinacea, Panax, and Camellia, which were used in maternal nutrition.

Abstract
The fundamental mechanisms underlying the preventional and therapeutic effects of polysaccharides from fungi, including the immunostimulatory, antiviral and antitumor effects, are considered to occur through the modulation and stimulation of the macrophage and complement system. LDG-A, a novel polysaccharide from Lactarius deliciosus (L. ex Fr.) Gray exhibits marked antitumor activities in vivo. However, the underlying molecular mechanism of the antitumor activities of LDG-A remains unclear. In the present study, cell cycle analysis was performed in macrophages and B cells, and the transcriptomes of macrophages in the control group and LDG-A group were sequenced using Illumina sequencing technology to analyze the differentially expressed genes (DEGs), and elucidate the molecular mechanisms underlying the immunomodulatory and antitumor activities of LDG-A. The cell cycle analysis results indicated that LDG-A was able to promote the proliferation of B cells by promoting cell cycle progression in S phase and G2/M phase and eliminating cell cycle arrest in G0/G1, and promote the proliferation of macrophages by promoting cell cycle progression in G0/G1 phase and eliminating cell cycle arrest in G2/M phase. Of the total number of genes (8,140), ~77.00% were expressed [reads per kilobase per million reads (RPKM) ≥1] and 1,352 genes were highly expressed (RPKM >60) in the LDG-A group. Of 775 unigenes which were identified as DEGs, 469 were downregulated and 306 genes were upregulated. A protein chip method was also used to determine the cytokines secreted by macrophages. Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis and GO enrichment analysis indicated that the Janus kinase/signal transducer and activator of transcription, mitogen-activated protein kinase, chemokine, vascular endothelial growth factor and transforming growth factor β signaling pathways are markedly enriched for DEGs.

Abstract
In this study, the immunomodulatory activity of oligopeptide (CP) derived from solid-state fermented cottonseed meal were investigated in immunosuppressed BALB/c mice models by treatment with cyclophosphamide (CY). Results indicated that oligopeptide increased the thymus and spleen indices of CY-treated mice. The count of plague forming cells (PFC) and the content of half serum hemolysis (HC50) in immunosuppressive mice were restored to the normal level in CP-10 and CP-20 groups while the cytokines interleukin (IL)-2, IL-6, and tumor necrosis factor alpha (TNF-α) were increased significantly in CP-20 group. Similar increasing the immunoglobulin of IgG and IgM content in the serum of CP-10 group were also observed. These findings indicated that oligopeptide derived from solid-state fermented cottonseed meal had a strong immune-enhancing activity as well as a protective effect against immunosuppression induced by cyclophosphamide in mice.

Abstract
Rhodomyrtus tomentosa is a medicinal plant that shows biological effects including immunomodulatory activity on human and other mammals but not in fish. In this study, we evaluated the in vitro immunomodulatory effects of R. tomentosa leaf extract and its active compound, rhodomyrtone, on the immune responses, using rainbow trout (Oncorhynchus mykiss) head kidney (HK) macrophages as a model. The tested immune functions included the expression of genes involved in innate immune and inflammatory responses and the production of reactive oxygen species (ROS). Gene expression was evaluated after exposure to 10 μg mL-1 of R. tomentosa and 1 μg mL-1 of rhodomyrtone for 4 and 24 h. R. tomentosa and rhodomyrtone induced changes in the expression of pro-inflammatory cytokines (il1β, il8, and tnfα), anti-inflammatory cytokines (il10 and tgfβ), inducible enzymes (inos, cox2, and arginase), and an antioxidant enzyme (gpx1). Co-exposure of R. tomentosa with LPS resulted in a prominent reduction in the expression of genes related to an inflammatory process (il1β, il8, tnfα, inos, saa, hepcidin, and gpx1), suggesting anti-inflammatory effects. Similarly, co-exposure of rhodomyrtone with LPS led to a downregulation of inflammation-related genes (il1β, inos, saa, and hepcidin). In addition, exposure to both natural plant products caused a reduction in cellular ROS levels by HK macrophages. The present results indicate that R. tomentosa and rhodomyrtone exerted immunostimulatory and anti-inflammatory effects on fish macrophages, thus opening up the possibility of using these natural products to further develop immunostimulants for health management in aquaculture.

Abstract
The innate immune system acts as the first line of defense against invasion by bacterial and viral pathogens. The role of macrophages in innate immune responses to foot-and-mouth disease virus (FMDV) is poorly understood. To determine the mechanism underlying activation of innate immunity after FMDV infection in macrophages, we performed FMDV infection in mouse macrophage RAW 264.7 cells and found that FMDV serotype O infection induced a cytopathic effect. We then evaluated the gene expression profile in macrophage RAW 264.7 cells after FMDV infection using systematic microarray analysis. Gene ontology annotation and enrichment analysis revealed that FMDV promoted expression in a group of genes that are enriched in innate immune response and inflammatory response processes. Further research demonstrated that FMDV serotype O infection enhanced NF-κB, Toll-like, and RIG-I-like receptor signaling pathways and proteins expression and increased transcription and expression of a series of cytokines and interferons, as proved by qRT-PCR, Western blot, ELISA, and dual-luciferase reporter assay. Our study concluded that FMDV infection triggers the innate immune response in macrophages after activation of multiple innate immune pathway receptors and proteins by FMDV serotype O, resulting in activation and secretion of a series of cytokines and interferons.

Abstract
BACKGROUND The mechanism of the immunoregulatory activities of polysaccharide is still not clear. MATERIALS AND METHODS Here, we performed the B-cell, T-cell, and macrophage cell proliferation, the cell cycle analysis of macrophage cells, sequenced the transcriptomes of control group macrophages, and Boletus speciosus Frost polysaccharide (BSF-1) group macrophages using Illumina sequencing technology to identify differentially expressed genes (DEGs) to determine the molecular mechanisms of immunomodulatory activity of BSF-1 in macrophages. RESULTS These results suggested that BSF-1 could promote the proliferation of B-cell, T-cell, and macrophages, promote the proliferation of macrophage cells by abolishing cell cycle arrests in the G0/G1 phases, and promote cell cycle progression in S-phase and G2/M phase, which might induce cell division. A total of 12,498,414 and 11,840,624 bp paired-end reads were obtained for the control group and BSF-1 group, respectively, and they corresponded to a total size of 12.5 G bp and 11.8 G bp, respectively, after the low-quality reads and adapter sequences were removed. Approximately 81.83% of the total number of genes (8,257) were expressed reads per kilobase per million mapped reads (RPKM ≥1) and more than 1366 genes were highly expressed (RPKM >60) in the BSF-1 group. A gene ontology-enrichment analysis generated 13,042 assignments to cellular components, 13,094 assignments to biological processes, and 13,135 assignments to molecular functions. A Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis showed that the mitogen-activated protein kinase (MAPK) signaling pathways are significantly enriched for DEGs between the two cell groups. CONCLUSION An analysis of transcriptome resources enabled us to examine gene expression profiles, verify differential gene expression, and select candidate signaling pathways as the mechanisms of the immunomodulatory activity of BSF-1. Based on the experimental data, we believe that the significant antitumor activities of BSF-1 in vivo mainly involve the MAPK signaling pathways. SUMMARY Boletus speciosus Frost-1 (BSF-1) could promote the proliferation of B-cell, T-cell, and macrophages, promote the proliferation of macrophage cells by abolishing cell cycle arrests in the G0/G1 phases, and promote cell cycle progression in S-phase and G2/M phase, which might induce cell divisionApproximately 81.83% of the total number of genes (8257) were expressed (reads per kilobase per million mapped reads [RPKM] =1) and more than 1366 genes were highly expressed (RPKM >60) in the BSF-1 groupA gene ontology-enrichment analysis generated 13,042 assignments to cellular components, 13,094 assignments to biological processes, and 13,135 assignments to molecular functionsA Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis showed that the mitogen-activated protein kinase signaling pathways are significantly enriched for DEGs between the two cell groups.

Polysaccharides from ginseng leaves inhibit tumor metastasis via macrophage and NK cell activation. Int J Biol Macromol 2017; 103:1327-1333.

Abstract
In this study, we purified the polysaccharide fraction (GS-P) from the leaves of Panax ginseng C.A. Meyer and analyzed its monosaccharide composition and antitumor and antimetastatic activity in vitro and in vivo. GS-P is a 10.2kDa pectic polysaccharide consisting of 15 different monosaccharides. GS-P treatment significantly inhibited metastasis in mice, in a dose-dependent manner. GS-P was not cytotoxic to colon 26-M3.1 cells and increased mouse splenocyte proliferation. Secretion of tumor necrosis factor (TNF)-α and interleukin (IL)-12 was enhanced in the peritoneal exudate macrophages (PEMs) of GS-P-treated mice. Moreover, PEMs obtained from GS-P-treated mice showed significantly higher tumoricidal activity against colon 26-M3.1 cells, and splenocytes from GS-P-treated mice significantly enhanced NK cell cytotoxicity against YAC-1 tumor cells. Pretreatment with anti-asialo GM1 (an antibody for NK cell depletion) partly suppressed the inhibitory effects of GS-P on lung metastasis. These data suggest that GS-P exhibits antimetastatic activity by promoting the activation of macrophages and NK cells.

Abstract
A new heteropolysaccharide was isolated from the fruiting bodies of Lactarius deliciosus Gray which had a molecular weight of 16kDa and was mainly composed of the galactose and glucose. Structural elucidation results indicated that Lactarius deliciosus Gray polysaccharide (LDG-B) had a backbone of (1,6)-linked d-galactose and (1, 2, 6)-linked d-galactose which branches were mainly composed of 4-linked d-glucose and 6-linked d-galactose residue. Cell cycle test results showed that LDG-B could promote the proliferation of B cells and macrophage cells by affecting G0/G1 phase, S phases and G2/M phases. The analysis of transcriptomes sequence of macrophages showed a total of 1839 genes were identified as DEGs, and approximately 708 genes were up-regulated, whereas 1131 genes were down-regulated in LDG-B group. KEGG pathway enrichment analysis showed that the MAPK, JAK-STAT and NF-κB signaling pathways are significantly enriched for DEGs in LDG-B group. Analysis of transcriptome resources enabled us to examine gene expression profiles, verify differential gene expression, and select candidate signaling pathways as the mechanisms of the immunomodulatory activity of LDG-B.

Abstract
Ginsan is a polysaccharide extracted from Panax ginseng that is known to have multiple immunomodulatory effects. This study evaluates the chemoprotective effect of ginsan on normal mice and the adjuvant effect on tumor bearing mice in combination with cyclophosphamide (CP). Ginsan (100 mg/kg) was injected 24 h before or after a sublethal dose of a CP treatment. The mice pre-treated with ginsan all died within 10 days whereas up to 53% of the mice post-treated with ginsan increased survival to day 30 compared with only 10% in the CP alone treated group on day 30. The post-treatment of ginsan accelerated the recovery of the bone marrow cells and blood neutrophils by approximately 1.3- and 1.75-fold compared to CP treated control mice at 5 days after CP administration, respectively. These marked differences in activity between the pre- and post-treatment of ginsan with CP was clarified by examining the mRNA expression levels of several cytokines in spleen cells and the self-renewal potential of hematopoietic progenitor cells, CFU-s. The post-treatment with ginsan increased the mRNA expression levels of TNF-α, IL-1β, IL-6, SCF, and GM-CSF with respect to that of the CP alone or ginsan pre-treated group. Similarly, the number of CFU-s was significantly higher in the mice post-treated with ginsan. The inhibition of tumor growth and survival elongation was also observed when ginsan was administered 24 h after the CP treatment. These results show that the post-treatment with ginsan had an immunomodulating and adjuvant effect in combination with CP, which indicates its wide applications in reducing the adverse effects of chemotherapy and improving the general conditions of patients.

Abstract
In the present study, we performed a proliferation assay, phagocytosis assay and cell cycle analysis of macrophages and sequenced the transcriptomes of control group macrophages and TMP-A group macrophages using Illumina sequencing technology to identify differentially expressed genes (DEGs) and determine the molecular mechanisms associated with differences in the immunomodulatory activity of TMP-A in macrophages. The results showed that TMP-A exhibits strong proliferation activity and phagocytosis activity in RAW264.7 cells in vitro and could also promote the proliferation of macrophage cells by abolishing cell-cycle arrest in the G0/G1 phase and promoting the cell cycle in the G2/M phase, which may induce cell division. A total of 12,616,096 and 11,798,839 bp paired-end reads were obtained for the control group and TMP-A group, respectively, and they corresponded to a total size of 12.5 G bp and 11.7 G bp, respectively, after the low-quality reads and adapter sequences were removed. Approximately 79.8% of the total number of genes (10,191) were expressed (RPKM ≥1), and more than 1,372 genes were highly expressed (RPKM >60) in the TMP-A group. A total of 1,043 unigenes were identified as DEGs, and approximately 486 genes were upregulated, whereas 557 genes were down-regulated, which might have contributed to the proliferation activity and phagocytosis activity of TMP-A in the RAW264.7 cells in vitro. A Gene Ontology (GO) enrichment analysis generated 13,042 assignments to cellular components, 13,094 assignments to biological processes, and 13,135 assignments to molecular functions. A KEGG pathway enrichment analysis showed that the MAPK and NF-κB signaling pathways are significantly enriched for DEGs between the two cell groups. Based on the experimental data, we believe that the significant antitumor activities of TMP-A in vivo involve the MAPK and NF-κB signaling pathways because the two signaling pathways intersect.

Abstract
Panax ginseng Meyer, belonging to the genus Panax of the family Araliaceae, is known for its human immune system-related effects, such as immune-boosting effects. Ginseng polysaccharides (GPs) are the responsible ingredient of ginseng in immunomodulation, and are classified as acidic and neutral GPs. Although GPs participate in various immune reactions including the stimulation of immune cells and production of cytokines, the precise function of GPs together with its potential receptor(s) and their signal transduction pathways have remained largely unknown. Animal lectins are carbohydrate-binding proteins that are highly specific for sugar moieties. Among many different biological functions in vivo, animal lectins especially play important roles in the immune system by recognizing carbohydrates that are found exclusively on pathogens or that are inaccessible on host cells. This review summarizes the immunological activities of GPs and the diverse roles of animal lectins in the immune system, suggesting the possibility of animal lectins as the potential receptor candidates of GPs and giving insights into the development of GPs as therapeutic biomaterials for many immunological diseases.

Abstract
Three new large hexanuclear metalla-prisms 9-11 incorporating 1,3, 5-tris(pyridin-4-ylethynyl)benzene (tpeb) 4 and one of the dinuclear arene ruthenium clips [Ru2(p-iPrC6H4Me)2(OO∩OO)][CF3SO3]2 (OO∩OO =2,5-dioxydo-1,4-benzoquinonato [dobq] 1, 5,8-dihydroxy-1,4-naphthaquinonato (donq) 2, and 6,11-dihydroxy-5,12-naphthacenedionato [dotq] 3), which encapsulate the guest molecule ellagic acid (2,3,7,8-tetrahydroxy-chromeno[5,4,3-cde]chromene-5,10-dione, 5) were prepared. All complexes were isolated as triflate salts in good yields and were fully characterized by (1)H NMR spectroscopy and electrospray ionization mass spectrometry. The photophysical properties of these metalla-prisms were also investigated. Compounds 9 and 10 showed potent antioxidant activity, but 10 had the superior ORACPE value (1.30 ± 0.020). Ellagic acid (5) and compound 11 showed weaker activity than that of Trolox. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay showed that the metalla-prism compounds exhibit anticancer properties in vitro. Compound 10 inhibited the growth of all cancer cell lines at micromolar concentrations, with the highest cytotoxicity observed against A549 human lung cancer cells (IC50 =25.9 μM). However, these compounds had a lower anti-cancer activity than that of doxorubicin. In a tumoricidal assay, ellagic acid (5) and compound 10 induced cytotoxicity in tumor cells, while doxorubicin did not. While free ellagic acid had no effect on the granulocyte-colony stimulating factor and regulated on activation normal T cell expressed and secreted protein, the encapsulated metalla-prism 10 stimulated granulocyte-colony stimulating factor and reduced regulated on activation normal T cell expressed and secreted protein expression in the RAW264.7 macrophage line. Our results show that ellagic acid encapsulated in metalla-prisms inhibited cancer cells via the modulation of mRNA induction and protein expression levels of the granulocyte-colony stimulating factor and regulated on activation normal T cell expressed and secreted protein in macrophages.

Abstract
It has been reported that Korean Red Ginseng has been manufactured for 1,123 y as described in the GoRyeoDoGyeong record. The Korean Red Ginseng manufactured by the traditional preparation method has its own chemical component characteristics. The ginsenoside content of the red ginseng is shown as Rg1: 3.3 mg/g, Re: 2.0 mg/g, Rb1: 5.8 mg/g, Rc:1.7 mg/g, Rb2: 2.3 mg/g, and Rd: 0.4 mg/g, respectively. It is known that Korean ginseng generally consists of the main root and the lateral or fine roots at a ratio of about 75:25. Therefore, the red ginseng extract is prepared by using this same ratio of the main root and lateral or fine roots and processed by the historical traditional medicine prescription. The red ginseng extract is prepared through a water extraction (90°C for 14–16 h) and concentration process (until its final concentration is 70–73 Brix at 50–60°C). The ginsenoside contents of the red ginseng extract are shown as Rg1: 1.3 mg/g, Re: 1.3 mg/g, Rb1: 6.4 mg/g, Rc:2.5 mg/g, Rb2: 2.3 mg/g, and Rd: 0.9 mg/g, respectively. Arginine-fructose-glucose (AFG) is a specific amino-sugar that can be produced by chemical reaction of the process when the fresh ginseng is converted to red ginseng. The content of AFG is 1.0–1.5% in red ginseng. Acidic polysaccharide, which has been known as an immune activator, is at levels of 4.5–7.5% in red ginseng. Therefore, we recommended that the chemical profiles of Korean Red Ginseng made through the defined traditional method should be well preserved and it has had its own chemical characteristics since its traditional development.

Abstract
The phagocyte-microbe interactions in the immune system is a defense mechanism but when excessively or inappropriately deployed can harm host tissues and participate in the development of different non-immune and immune chronic inflammatory diseases such as autoimmune problems, allergies, some rheumatoid disorders, cancers and others. Immunodrugs include organic synthetics, biological agents such as cytokines and antibodies acting on single targets or pathways have been used to treat immune-related diseases but with limited success. Most of immunostimulants and immunosuppressants in clinical use are the cytotoxic drugs which possess serious side effects. There is a growing interest to use herbal medicines as multi-component agents to modulate the complex immune system in the prevention of infections rather than treating the immune-related diseases. Many therapeutic effects of plant extracts have been suggested to be due to their wide array of immunomodulatory effects and influence on the immune system of the human body. Phytochemicals such as flavonoids, polysaccharides, lactones, alkaloids, diterpenoids and glycosides, present in several plants, have been reported to be responsible for the plants immunomodulating properties. Thus the search for natural products of plant origin as new leads for development of potent and safe immunosuppressant and immunostimulant agents is gaining much major research interest. The present review will give an overview of widely investigated plant-derived compounds (curcumin, resveratrol, epigallocatechol-3-gallate, quercetin, colchicine, capsaicin, andrographolide, and genistein) which have exhibited potent effects on cellular and humoral immune functions in pre-clinical investigations and will highlight their clinical potential.

Abstract
Background Antiallergic effect of 20(S)-protopanaxatriol (PPT), an intestinal metabolite of ginseng saponins, was investigated in guinea pig lung mast cells and mouse bone marrow-derived mast cells activated by a specific antigen/antibody reaction. Methods Increasing concentrations of PPT were pretreated 5 min prior to antigen stimulation, and various inflammatory mediator releases and their relevant cellular signaling events were measured in those cells. Results PPT dose-dependently reduced the release of histamine and leukotrienes in both types of mast cells. Especially, in activated bone marrow-derived mast cells, PPT inhibited the expression of Syk protein, cytokine mRNA, cyclooxygenase-1/2, and phospholipase A2 (PLA2), as well as the activities of various protein kinase C isoforms, mitogen-activated protein kinases, PLA2, and transcription factors (nuclear factor-κB and activator protein-1). Conclusion PPT reduces the release of inflammatory mediators via inhibiting multiple cellular signaling pathways comprising the Ca2+ influx, protein kinase C, and PLA2, which are propagated by Syk activation upon allergic stimulation of mast cells.

Abstract
Background The Y-75 (Ginsan) acidic polysaccharide from Korean Panax ginseng has been shown to function as an immunomodulatory molecule. However, the efficacy of Y-75 has not been evaluated in clinical trial. Methods We verified Y-75 (6 g/day) for safety and immune efficacy in 72 healthy volunteers aged 50–75 years using a randomized, placebo-controlled, parallel, double-blind study. The activities of natural killer (NK) cells and peripheral blood phagocytes, as well as serum levels of monocyte-derived mediators, were assessed before and after administration for 8 and 14 weeks. This trial is registered at ClinicalTrials.gov (NCT02161198). Results Y-75 significantly enhanced NK cell cytotoxic activity by 35.2% and 40.2% from baseline after administration for 8 and 14 weeks, respectively. The phagocytic activity of peripheral blood cells was also significantly increased by 25.2% and 39.4% and serum level of TNF-α by 38.2% and 44.5% after treatment for 8 and 14 weeks, respectively. Differences in the efficacy of variables compared to the placebo group were also significant. Administration of Y-75 was well tolerated without treatment-related adverse events or alteration of complete blood cell count or blood chemistry over the entire study period. Conclusion Y-75 was shown to be a safe and potentially effective natural alternative for enhancing immune function.

Abstract
Morin, a natural flavonoid that is the primary bioactive constituent of the family Moraceae, has been found to be associated with many therapeutic properties. In this study, we evaluated the immunomodulatory activities of increasing concentration of morin hydrate in vitro. Three different concentrations of morin hydrate (5, 10, and 15μM) were used to evaluate their effect on splenocyte proliferation, phagocytic activity of macrophages, cytokine secretion and complement inhibition. We also evaluated the role of morin hydrate on lipopolysaccharide (LPS) induced autophagy. Our study demonstrated that morin hydrate elicited a significant increase in splenocyte proliferation, phagocytic capacity and suppressed the production of cytokines and nitric oxide in activated macrophages. Humoral immunity measured by anti-complement activity showed an increase in inhibition of the complement system after the addition of morin hydrate, where morin hydrate at 15μM concentration induced a significant inhibition. Depending on our results, we can also conclude that morin hydrate protects macrophages from LPS induced autophagic cell death. Our findings suggest that morin hydrate represents a structurally diverse class of flavonoid and this structural variability can profoundly affect its cell-type specificity and its biological activities. Supplementation of immune cells with morin hydrate has an upregulating and immunoprotective effect that shows potential as a countermeasure to the immune dysfunction and suggests an interesting use in inflammation related diseases.

Abstract
Polyphenols including 3-glucoside/arabinoside/galactoside-based polymers of delphinidins, petunidins, peonidins, malvidins and cyanidins are one type of biological macromolecules, which are extraordinarily rich in blueberries. Anti-inflammatory activity of blueberry polyphenols (BPPs) was investigated by using lipopolysaccharide (LPS) induced RAW264.7 macrophages. The results showed that BPPs suppressed the gene expression of IL-1β (interleukin-1β), IL-6 and IL-12p35. The inhibition effect on IL-1β and IL-6 mRNA was most obvious at the concentration of 10-200μg/mL BPPs. But the inhibition effect on IL-12p35 mRNA was increased with the increasing concentration of BPPs. When fixed at 100μg/mL BPPs, the most significant inhibition on IL-1β, IL-6 and IL-12p35 mRNA expression was detected at 12-48h. In conclusion, BPPs exhibit anti-inflammation activity by mediating and modulating the balances in pro-inflammatory cytokines of IL-1β, IL-6, and IL-12.

Abstract
Owing to its susceptibility to radiation, the small intestine of mice is valuable for studying radioprotective effects. When exposed to radiation, intestinal crypt cells immediately go through apoptosis, which impairs swift differentiation necessary for the regeneration of intestinal villi. Our previous studies have elucidated that acidic polysaccharide of Panax ginseng (APG) protects the mouse small intestine from radiation-induced damage by lengthening villi with proliferation and repopulation of crypt cells. In the present study, we identified the molecular mechanism involved. C57BL/6 mice were irradiated with gamma-rays with or without APG and the expression levels of apoptosis-related molecules in the jejunum were investigated using immunohistochemistry. APG pretreatment strongly decreased the radiation-induced apoptosis in the jejunum. It increased the expression levels of anti-apoptotic proteins (Bcl-2 and Bcl-XS/L) and dramatically reduced the expression levels of pro-apoptotic proteins (p53, BAX, cytochrome c and caspase-3). Therefore, APG attenuated the apoptosis through the intrinsic pathway, which is controlled by p53 and Bcl-2 family members. Results presented in this study suggest that APG protects the mouse small intestine from irradiation-induced apoptosis through inhibition of the p53-dependent pathway and the mitochondria/caspase pathway. Thus, APG may be a potential agent for preventing radiation induced injuries in intestinal cells during radio-therapy such as in cancer treatment.

Abstract
This study was designed to investigate the effects of oral administration of the polysaccharide from the Radix Cyathulae officinalis Kuan (RCPS) for its adjuvant potential on the specific cellular and humoral immune responses in mice. In this study, our data demonstrated that oral administration of RCPS significantly enhanced the phagocytic capacity of peritoneal macrophage, splenocyte proliferation, the activity of natural killer (NK) cells and cytotoxic T lymphocytes (CTL) and OVA-specific IgG, IgG1, IgG2a, and IgG2b antibody titers. Furthermore, RCPS promoted the level of interleukin-2(IL-2), IFN-γ and IL-4 in CD4(+)T cells and level of IFN-γ in CD8(+)T cells. In addition, RCPS enhanced the expression of CD40(+), CD80(+) and CD86(+) on the dendritic cells (DCs). Importantly, RCPS down-regulated the frequency of CD4(+)CD25(+)Foxp3(+)Treg cells. Taken together, these results suggested that RCPS could increase both cellular and humoral immune responses via up-regulating DCs maturation, and suppressing Treg frequency.

Herbs/Botanical plants are considered as God's gift to human beings in the form of natural medicines, like the one well known "Sanjeevani booti" described in Hindu Mythology. The traditional and ethno-veterinary practices have been in use for centuries, transferring the knowledge from generation to generation and they are accessible, easy to prepare and administer, with little or no cost at all. Even though the modern developments in therapeutic field brought about a rapid decline in traditional medicine, the plant-based remedies are still having a crucial role as potential source of therapeutic aids in health systems all over the world for both humans and animals. Among the 21,000 medicinal plants listed by the World Health Organization (WHO), 2500 species are native to India, which stands first in the production of medicinal herbs. This innumerable treasure of medicinal herbs brings India the distinction of 'the botanical garden of the world'. Nowadays immune-based therapies are gaining more importance than monovalent approaches which are having limited benefits. Apart from the actions like treating diseases, control of ecto- and endo-parasites, fertility enhancement, bone setting and poor mothering management, an array of herbal medicines have been reported which are having immunomodulatory effects like modulation of cytokine secretion, histamine release, immunoglobulin secretion, class switching, cellular co-receptor expression, lymphocyte expression, phagocytosis and so on. The present article describes in brief few of these important ones viz., ashwagandha, amla, tulsi, arjuna, aloe vera, garlic, turmeric, ginger, shatavari, neem, guduchi, kiwifruit, tut, kamala, palashlata, kokilaksha etc. being used for human and animal health benefits.

Abstract
Chemical radiation protection is an important strategy to protect living beings against the deleterious effects of radiation. In the present study, the radioprotective effect of hydro-alcoholic extract of Panax ginseng extract (PGR-HAE) was studied on radiation-induced deleterious alterations in Swiss albino mice. Oral administration of such extract (25 mg/kg b wt/day/animal) for 5 consecutive days, half an h. before whole-body exposure to 6 Gy gamma radiation, enhanced the 30 days survival and also inhibited the radiogenic sickness, weight loss and life shortening. PGR-HAE ameliorated radiation induced depletion in blood constituents at different necropsy intervals between 12 h to 30 d, and significantly increased the number of femoral spleen colony forming units that survived after irradiation. Furthermore, it checked depletion of glutathione and antioxidant enzymes (superoxide dismutase, catalase, and glutathione S-transferase) as well as elevation of lipid peroxidation (LPO) level in blood and liver. The significant reduction in the yield of LPO demonstrates that PGR-HAE protects the membranes against radiation-induced oxidative damage. These findings conclude that such plant extract provides significant radioprotection, and it may be potentially valuable in the prevention of injuries caused during planned and unplanned radiation exposure.

Abstract
AIMS Phragmites rhizoma was reported to have anti-oxidative and free radical scavenging activity. It also has been traditionally used to suppress inflammation. In the present study, we aimed to evaluate the topical effects of the polysaccharide-rich extract of P. rhizoma (PEP) on atopic dermatitis. MAIN METHODS We induced AD-like skin lesions by an extract of the house-dust mite Dermatophagoides farinae (Dfb) in NC/Nga mice, and then performed macroscopic analysis, immunohistochemical staining and measurement of total serum IgE and cytokine production by ELISA. KEY FINDINGS Topically applied PEP suppressed dermatitis with a decrease in dermatitis score and scratch number. The histological manifestations of atopic skin lesions including thickened epidermis and increased numbers of mast cells, polymorphonuclear leukocytes and nerve fibers were significantly attenuated. The activation of IgE and the levels of cytokines such as IFN-γ IL-4 and IL-10 were also decreased. SIGNIFICANCE Our results indicated that PEP might have an inhibitory effect on atopic dermatitis-like lesion and be a promising natural resource in the treatment of atopic dermatitis.

Abstract
This is the first report of the successful treatment of advanced biliary tract cancer with gemcitabine single-agent chemotherapy in combination with Juzen-taiho-to (JTT), a Japanese traditional herbal medicine. An 84-year-old woman was referred to our hospital with general fatigue and appetite loss; she was diagnosed with advanced biliary tract cancer and accompanying colonic invasion and hepatic metastasis. The patient's response to combination chemotherapy was extremely good, and her tumors disappeared. Recent studies have confirmed the occurrence of spontaneous and induced antitumor immune responses, carried out by tumor-infiltrating lymphocytes in the tumor microenvironment. The availability, antigen presentation, and proliferation of these immune cells are increased by cytokines such as granulocyte macrophage colony-stimulating factor (GM-CSF) and interleukin (IL)-2. Recently, JTT has gained recognition as a biological response modifier that has stimulatory effects on systemic immune responses such as enhancement of cytokine expression (GM-CSF, IL-2, etc.). In addition, some chemotherapy agents, such as anthracyclines and gemcitabine, are effective boosters of the immune response through tumor-specific antigen overexpression after apoptotic tumor cell destruction. These findings suggest that JTT enhances the antitumor effects of gemcitabine, in particular its tumor-specific effects on immune response, and these drugs are a good combination for advanced biliary tract cancer therapy.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Traditionally, chicken embryo eggs are widely considered as an immunomodulatory health product in China and southeast Asia. Besides that, Compendium of Materia Medica, the most famous Chinese pharmacopoeia, has recorded that chicken embryo eggs contributed to the appetite increase and immune function enhancement, especially for the pregnant and aged. AIM OF THE STUDY Through assessing the immune efficacy of the chicken embryo extracts on immunocompetent cells, the immunomodulatory mechanism and components were explored preliminarily. MATERIALS AND METHODS The raw material was subjected to in vitro gastric and pancreatic digestion successively, and then ligarine was added to separate the digested mixture to water-soluble fraction (WS) and lipid-soluble fraction (LS). Employing in vitro cell models, the immunomodulating activities of the extracts on immunosuppressed mouse were examined, at concentrations ranging from 10 to 500 μg/ml. The cell experiments consisted of the following experiments: spleen lymphocyte proliferation and IL-2 secretion, peritoneal macrophage phagocytosis and NO production. Before cell experiments, Kjeldal method and phenol-sulfuric acid method were employed respectively to determine the total protein and polysaccharide content of WS, and gas chromatography to analyze the fatty acid composition of LS. RESULTS LS significantly enhanced the spleen lymphocyte proliferation and IL-2 secretion, while peritoneal macrophage phagocytosis and NO production activity were elevated by WS. Both extracts exhibited an immunomodulatory effect with a dose-effect relationship. CONCLUSION The findings confirmed the chicken embryo eggs as a potent immunopotentiator on the immunosuppressed mouse, which would be useful for the fruitful application of the chicken embryo eggs to serve as a superior immunostimulatory tonic. Furthermore, the two extracts exhibited a different bioactivity tendency which makes it a significative work to screen the bioactive component for further study.

Abstract
The aim of the study was to determine the effect of ginseng and echinacea on the mRNA expression of IL-10, TNF-α, and TGF-β1 in healthy rats. Six-week-old male Fischer 344 rats (n = 48) were used. The animals were divided into three equal groups, as follows: control (C); ginseng (G); echinacea (E). While the C group was fed a standard rat diet (Purina) ad libitum for a period of 40 days, the G and E groups animals received the same diet containing 0.5 g/kg of Panax ginseng root powder and 0.75 g/kg of Echinacea purpurea root powder, respectively. Blood samples were obtained from 8 rats in each group after 20 and 40 days of treatment, and the mRNA expression of IL-10, TNF-α, and TGF-β1 was determined. After 20 days of treatment, the expression of IL-10 mRNA in the G group was different from the C group (P < 0.05); however, after 40 days of treatment, there was no difference between the groups. There was no difference after 20 and 40 days of treatment between the groups with respect to the expression of TGF-β1 mRNA. After 20 days of treatment, the expression of TNF-α mRNA in the E group was higher (P < 0.05) than the C group. After 40 days of treatment, the expression of TNF-α mRNA was similar in all of the groups. Based on the current study, the increase in expression of IL-10 mRNA in the G group and the increase in expression of TNF-α mRNA in the E group support the use of these plants for purposes of modulating the immune system. However, a more detailed study regarding the effects of ginseng and echinacea on these cytokines and other cytokines is needed.
