Abstract
Tumor is a serious threat to human health, with extremely high morbidity and mortality rates. However, tumor treatment is challenging, and the development of antitumor drugs has always been a significant research focus. Plant polysaccharides are known to possess various biological activities. They have many pharmacological properties such as immunomodulation, antitumor, antiviral, antioxidative, antithrombotic, and antiradiation effects, reduction of blood pressure and blood sugar levels, and protection from liver injury. Among these effects, the antitumor effect of plant polysaccharides has been widely studied. Plant polysaccharides can inhibit tumor proliferation and growth by inhibiting tumor cell invasion and metastasis, inducing cell apoptosis, affecting the cell cycle, and regulating the tumor microenvironment. They also have the characteristics of safety, high efficiency, and low toxicity, which can alleviate, to a certain extent, the adverse reactions caused by traditional tumor treatment methods such as surgery, radiotherapy, and chemotherapy. Therefore, this paper systematically summarizes the direct antitumor effects of plant polysaccharides, their regulatory effects on the tumor microenvironment, and intervening many common high-incidence tumors in other ways. It also provides data support for the administration of plant polysaccharides in modern tumor drug therapy, enabling the identification of new targets and development of new drugs for tumor therapy.

Vatke (Rubiaceae) to Combat Co-Infection of Tuberculosis and Helminthiasis. Front Pharmacol 2022; 12:744137. [PMID: 35087402 PMCID: PMC8787188 DOI: 10.3389/fphar.2021.744137] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2021] [Accepted: 12/16/2021] [Indexed: 11/15/2022] Open
Abstract
Tuberculosis (TB) is a disease of global importance that affects millions of people. Approximately a quarter of the world’s population is currently infected with M. tuberculosis, and about 10% of those infected will develop into active disease, particularly immune compromised individuals. Helminthiasis is of global health importance, affecting over 2 billion people mostly in resource-poor countries. Co-infection with tuberculosis (TB) and helminths (worms) is an emerging global public health concern with both affecting about one-third of the global population. Chronic infection with helminths can result in impaired immune responses to TB as well as enhancing failure to TB therapy and BCG vaccination. Antimycobacterial and anthelmintic activities of the acetone extract and fractions of Psychotria capensis were evaluated, including their in vitro safety. In addition, the anti-inflammatory and immunomodulatory effect of the fractions and crude extract of P. capensis were assessed. Antimycobacterial activity of the extract and fractions was tested against four non-tuberculous mycobacteria (Mycobacterium smegmatis, M. fortuitum, M. aurum, M. bovis BCG) and pathogenic M. tuberculosis H37Rv while the Egg Hatch Assay (EHA) was used for the anthelmintic test on eggs of Haemonchus contortus. Cytotoxicity was determined against Vero kidney cells while in vitro immune modulation via cytokine production was determined on activated macrophages. The minimum inhibitory concentration (MIC) values of the Psychotria capensis acetone extract and fractions ranged from 39 to 1,250 μg/ml with the crude extract and hexane fraction having the best MIC values (both 39 μg/ml). In the EHA, the inhibitory concentration (IC50) ranged from 160 to 630 μg/ml with the hexane fraction having the best activity. The hexane and chloroform fractions were relatively non-toxic with LC50 values of 290 and 248 μg/ml respectively, while the acetone crude extract (64 μg/ml) and n-butanol fraction (71 μg/ml) were moderately toxic. The SI values (LC50/MIC) ranged from 0.1 to 7.4 with the hexane fraction having the highest value against M. smegmatis (7.4). The hexane fraction had the best dual anthelmintic and antimycobacterial activity. This fraction had the best NO inhibitory activity and was the least cytotoxic, indicating that its activity was not due to general metabolic toxicity, with 96.54% cell viability. Pro-inflammatory cytokines such as IL-12p70 were upregulated while IL-10 expression was inhibited by the extracts. Compounds were detected using GC-MS analysis, and in both the crude acetone extract and the hexane fraction was the diterpene neophytadiene, which has anti-inflammatory and antimicrobial activity. Finding alternative or complementary approaches to dealing with TB infections by, amongst other things, reducing the incidence of helminth infestations may lessen the burden of TB, contributing to slowing the spread of multi-drug resistance.

Abstract
Boosting or suppressing our immune system represents an attractive adjunct in the treatment of infections including SARS-CoV-2, cancer, AIDS, malnutrition, age related problems and some inflammatory disorders. Thus, there has been a growing interest in exploring and developing novel drugs, natural or synthetic, that can manipulate our defence mechanism. Many of such studies, reported till date, have been designed to explore effect of the therapeutic on function of macrophages, being a key component in innate immune system. Indeed, RAW264.7, J774A.1, THP-1 and U937 cell lines act as ideal model systems for preliminary investigation and selection of dose for in vivo studies. Several bioassays have been standardized so far where many techniques require high throughput instruments, cost effective reagents and technical assistance that may hinder many scholars to perform a method demanding compilation of available protocols. In this review, we have taken an attempt for the first time to congregate commonly used in vitro immune-modulating techniques explaining their principles. The study detected that among about 40 different assays and more than 150 sets of primers, the methods of cell proliferation by MTT, phagocytosis by neutral red, NO detection by Griess reaction and estimation of expression of TLRs, COX-2, iNOS, TNF-α, IL-6 and IL-1β by PCR have been the most widely used to screen the therapeutics under investigation.

Abstract
Glycosyltransferase-producing Leuconostoc lactis CCK940 produces CCK- oligosaccharides, gluco-oligosaccharide molecules, using sucrose and maltose as donor and acceptor molecules, respectively. In this study, the immunostimulatory activities of CCK-oligosaccharides on RAW264.7 macrophages and BALB/c mice were evaluated. CCK-oligosaccharides induced the expression of phosphorylated-p38, extracellular-signal-regulated kinase (ERK), and c-Jun N-terminal kinase (JNK) and upregulation of phagocytic activity in RAW264.7 macrophages, suggesting their involvement in mitogen-activated protein kinase (MAPK) signaling pathway and phagocytosis. When CCK-oligosaccharides were administered to mice intraperitoneally injected with cyclophosphamide (CY), spleen indices and expressions of interleukin (IL)-6, IL–10, and tumor necrosis factor-α increased, compared with those in only CY-treated group. These findings suggest that CCK-oligosaccharides can be used as an effective immunostimulating agent.

Abstract
We report here an acidic polysaccharide, namely RSP-3, which ameliorates acute kidney injury and is obtained from Sanguisorba officinalis. We extracted and purified two polysaccharides from this herb based on the acidity and screened them for their effect in regulating the immunological activity of macrophages. Among them, RSP-3 exhibited significant anti-inflammatory activity against lipopolysaccharide (LPS)-stimulated macrophages by decreasing TNF-α and IL-6 levels. Subsequently, we found that RSP-3 suppressed ER stress, reduced ROS production and blocked NF-κBp65 translocation. After fully characterizing RSP-3 with a series of analytical technologies, we tested its anti-acute kidney injury (AKI) effect in vivo. In a murine AKI model induced by LPS, treatment with RSP-3 effectively ameliorated renal function. Besides, it decreased the levels of TNF-α and IL-6 in serum and reduced macrophage infiltration in injured kidney tissue. In sum, RSP-3, with a significant protective effect against AKI by showing anti-inflammatory activity, may become a meaningful drug candidate for treatment of AKI.

Abstract
Plethora of clinical and scientific information obtained in recent past has strengthened the idea that targeting critical constituents of host immune system may have beneficial outcomes for the treatment of tuberculosis. Macrophages being the primary host for Mycobacterium tuberculosis, offer an attractive target for modulation. Owing to their negligible toxicity, plant derived polysaccharides with the ability to activate macrophages; are suitable candidates for immunomodulation. In the present study, effects of polysaccharide rich extract (PRE) isolated from Tinospora cordifolia, on the survival of intracellular MTB strains and activation of macrophages were investigated. PRE treatment up regulated the expression of pro-inflammatory cytokines such as IL-β, TNF-α, IL-6, IL-12, and IFN-γ in RAW 264.7 cell line. Up regulation in the expression of NOS2 was observed along with concomitant enhanced nitric oxide production post PRE treatment. Surface expression of MHC-II and CD-86 was up regulated after PRE treatment. Above results suggested the classical activation of macrophages by PRE treatment. Furthermore, PRE treatment led to the activation of all the three classes of MAPK i.e p38, ERK and JNK MAPKs. Further, PRE up regulated the expression of cytokines, NOS-2, MHC-II and CD-86 in MTB infected macrophages. PRE treatment inhibited the intracellular survival of drug resistant MTB in macrophages which was partially attributed to PRE mediated NO induction. Thus our data demonstrate classical activation of macrophages by PRE treatment and killing of intracellular MTB by NO induction.

Abstract
Russula senecis has recently been reported as a new addition to macrofungal flora of West Bengal. Besides, it also emerged as a seasonal health promoting nutrient to local ethnic people and enlisted for the first time as tribal food in our previous publication. In this context, the present work was designed to establish such usefulness scientifically and to meet the aim, crude polysaccharide, Rusenan, was prepared using conventional heated water reflux. Initially, the polymers were characterized to determine chemical composition and for that spectrophotometry along with Fourier-transform infrared spectroscopy (FT-IR), high-performance thin-layer chromatography (HPTLC), and gas chromatography-mass spectrometry (GC-MS) were performed. Analysis indicated that Rusenan was consisted mainly of carbohydrate conjugated with trace amount of protein. Furthermore, glucose was detected as the major monosaccharide (mainly in β-type glycosidic linkage) while other monomers were presented in the order of galactose > mannose > xylose > rhamnose. Conversely, antioxidant potential was determined following eight in vitro systems where the fraction evidenced strong superoxide, hydroxyl, 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) radical scavenging activity, high affinity to Fe2+ as well as instant ability to donate electron with EC50 values ranging from 80 to 3885 μg/ml concentration. In addition, effect on murine macrophages was also investigated where the polysaccharide treatment increased cell proliferation, phagocytic activity, filopodia or lamellipodia formation, nitric oxide (NO) production and reactive oxygen species (ROS) synthesis. Thereafter, through reverse transcriptase polymerase chain reaction (RT-PCR) analysis, significant increase in the expression of Toll like receptor (TLR)-4, TLR-2 and nuclear factor kappa B (NF-κB) was observed; as a result alleviated level of cyclooxygenase (COX)-2, inducible nitric oxide synthase (iNOS), tumor necrosis factor (TNF)-α, IκB-α, and interferon (IFN)-γ were also noticed explaining definite immune-stimulatory activity of the fraction. Thus, overall finding suggests that R. senecis can be considered as a functional food and may be used in preparation of dietary supplement to enhance general health.

Abstract
Abstract
Objectives
Over past decades, investigation on bioactive polysaccharides extracted from mushroom by heated water reflux has been an emerging field of biomedicine especially in the area of immune stimulation. While studies with macromolecules isolated from remainder residue of aqueous extraction are scarce. In this context, crude polysaccharide from a traditionally edible macrofungus, Russula senecis, was prepared (RuseCap) by alkaline solvent using leftover residue of that conventional process and its structural along with therapeutic properties were evaluated.
Key findings
Investigation by FT-IR, HPTLC, GC-MS and spectrophotometry showed that the fraction was mainly consisted of carbohydrate with backbone of xylose, rhamnose, mannose and glucose (mostly β-glucan). Besides, RuseCap exhibited strong antioxidant activity evident by radical scavenging (superoxide, hydroxyl, DPPH, ABTS), chelating ability and reduction power where EC50 values ranged from 257 to 4068 μg/ml concentration. In addition, it also exhibited immune-boosting potentiality as the treatment effectively induced proliferation, phagocytosis, nitric oxide production, intracellular reactive oxygen species generation, morphological changes and increased transcription level of iNOS, COX-2, TNF-α, IL-6 genes in macrophage cells.
Conclusions
Overall, the study provided blueprint for extended utilization of R. senecis basidiocarps beyond hot water process and defined use of RuseCap as potent therapeutic agent against free radicals as well as deprived immunity.

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.

Introducing a novel mushroom from mycophagy community with emphasis on biomedical potency. PLoS One 2017; 12:e0178050. [PMID: 28552988 PMCID: PMC5446119 DOI: 10.1371/journal.pone.0178050] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2017] [Accepted: 05/05/2017] [Indexed: 01/05/2023] Open
Abstract
Mushrooms have been prized by humankind as medicine and culinary wonder since antiquity. Though several species are ethnically valued; many prospective species are still being discovered. One such wild macrofungus has recently been discovered during subsequent field surveys in West Bengal, India which in turn exposed as a traditionally consumed popular myco-food. The collected taxon was found to be unique with regard to its morphological as well as genetical features. After detailed characterizations, the fungus was identified as a novel taxon belonging to the genus Russula (Russulaceae, Basidiomycota). Besides, the investigation was further extended in search of new functional ingredients and in this context, a water soluble crude polysaccharide rich extract (Rusalan) was isolated from dried basidiocarps. Accumulating evidences from GC-MS, HPTLC, FT-IR along with several spectrophotometric methods postulated that the fraction consisted mainly of carbohydrate in triple helical conformation, where glucose was the major monosaccharide mostly with β-type glycosidic linkage. Conversely, Rusalan showed pronounced antioxidant activity in six in vitro assay systems with EC50 value ranging from 190–1328 μg/ml concentration. The crude polysaccharide was also evaluated against six bacterial strains using microdilution method and the growth of Staphylococcus aureus and Bacillus subtilis were found to be inhibited effectively. In addition, immune-stimulatory assays demonstrated that Rusalan could evidently promote proliferation, induce phagocytosis, release NO, produce intracellular ROS and upregulate mRNA expression of iNOS, TNF-α, COX-2, as well as IL-6 genes in in mouse macrophage cells. Therefore, aim of the present study was not only to describe a new taxon to the world mycoflora but also to introduce a potent therapeutic agent that could be explored for food and pharmaceutical purposes. However, isolation of active component and in vivo studies need to be designed further.

Abstract
To investigate the antitumor and antimetastatic polysaccharide from the mature leaves of green tea, GTE-II was purified using size exclusion chromatography. GTE-II consisted of 15 different sugars including rarely observed sugars such as 2-O-methyl-fucose, 2-O-methyl-xylose, apiose, aceric acid, 3-deoxy-d-manno-2-octulosonic acid, and 3-deoxy-d-lyxo-2-heptulosaric acid, which were characteristics of pectic polysaccharide rhamnogalacturonan-II. Treatment of peritoneal macrophages with GTE-II not only increased interleukin (IL)-6 and IL-12 production, but also had significantly increased tumoricidal activity against Yac-1 tumor cells than those obtained from untreated mice. In an assay of natural killer (NK) cell activity, intravenous administration of GTE-II significantly stimulated NK cytotoxicity against Yac-1 tumor cells. Furthermore, the depletion of NK cells by injection of rabbit anti-asialo GM1 serum eliminated the inhibitory effect of GTE-II on B16BL6 melanoma cells. These data suggest that GTE-II inhibits tumor metastasis, and its antitumor effect is associated with activation of macrophages and NK cells.

Int J Biol Macromol 2016; 92:185-193.

Abstract
A polysaccharide fraction from Solanum nigrum, SN-ppF3 was shown previously to have an immunomodulatory activity where it could possibly be used to enhance the host immune response in fighting cancer. The non-toxic SN-ppF3 was fed orally to breast tumor bearing-mice with concentrations of 250 and 500mg/kg for 10days. During the treatment period, size of the tumor and weight of the mice were monitored. At the end of the treatment, blood, tumor, spleen and thymus were harvested for physiological and immunological analyses. After the treatment, the tumor volume and tumor weight were significantly inhibited by 65% and 40%, respectively. Based on the histological observation, the treatment of SN-ppF3 resulted in the disruption of tumor cells morphology. The increase in infiltrating T cells, NK cells and macrophages were observed in tumor tissues of the treated mice, which partly explained the higher apoptosis tumor cells observed in the treated mice. Moreover, the level of TNF-α, IFN-γ and IL-4 were elevated, while the level of IL-6 was decreased significantly, in serum of the treated mice. These results suggested that tumor suppression mechanisms observed in SN-ppF3-treated mice were most probably due through enhancing the host immune response.

Abstract
Enterohaemorrhagic Escherichia coli (E. coli) O157:H7 is one of the most virulent causative agents of foodborne disease. Use of antibiotics for the treatment against E. coli O157:H7 infection leads to hemolytic uremic syndrome. The present study evaluated the potential of ethanolic leaf extract of a medicinal plant, Rhodomyrtus tomentosa in enhancing the killing activity of human neutrophils against E. coli O157:H7. In addition, the effects of the extract on membrane permeability of the organisms were studied. In the killing assay, percentage survival of the bacterial cells after being exposed to human neutrophils in the presence of various concentrations of the extract were determined. At 45 min, percentage survival of E. coli O157:H7 and E. coli ATCC 25922 after treated with neutrophils in the presence of the extract at 125-250 µg/mL was 58.48%-50.28% and 69.13%-35.35%, respectively. Furthermore, upon treatment with R. tomentosa at 250 µg/mL uptake of crystal violet by E. coli O157:H7 and E. coli ATCC 25922 was increased to 40.07% and 36.16%, respectively. Therefore, it is suggested that the extract exhibited dual effects as immunostimulant and membrane permeabilizing agent perhaps resulted in enhancing the killing activity of neutrophils against the organisms.

Abstract
Two new cystine knot peptides, asteropsins F (ASPF) and G (ASPG), were isolated from the marine sponge Asteropus sp. ASPF and ASPG are composed of 33 and 32 amino acids, respectively, and contain six cysteines which are involved in three disulfide bonds. They shared the characteristic features of the asteropsin family, such as, N-terminal pyroglutamate modification, incorporation of cis prolines, and the unique anionic profile, which distinguish them from other knottin families. Tertiary structures of the peptides were determined by high resolution NMR. ASPF and ASPG were found to be remarkably resistant not only to digestive enzymes (chymotrypsin, pepsin, elastase, and trypsin) but also to thermal degradation. In addition, these peptides were pharmacologically inert; non-hemolytic to human and fish red blood cells, non-stimulatory to murine macrophage cells, and nontoxic in vitro or in vivo. These observations support their stability and biocompatibility as suitable carrier scaffolds for the design of oral peptide drug.

Abstract
A low molecular weight polysaccharide was identified from the flower of Abelmoschus manihot (Linn.) Medicus, a popular herbal medicine also known as Flos A. manihot. The polysaccharide, AMPS-a, was obtained from the ethanol-extracted debris of Flos A. manihot by successive purification through DEAE-cellulose-52 and Sephadex G-100 column. AMPS-a has an estimated molecular weight of 8.8×10(3)Da and is mainly composed of β-d-glucose, α-d-mannose, α-d-galactose and α-l-fucose at a molar ratio of 1.00:0.91:2.14:1.09. The preliminary structural features were studied by hydrolysis-methylation analysis, GC-MS, FT-IR and (1)H and (13)C NMR spectroscopy. AMPS-a contains a backbone composed of repeating units of →6)α-d-Galp-(1→6)α-d-Manp-(1→6)α-d-Galp-(1→ with β-d-Glcp (1→3)α-Fucp-(1→ branching at O-3 of mannose. AMPS-a exhibited potent inhibitory effects on the proliferation of hepatic (SMMC-7721, HepG2) and gastric (MGC-803, MKN-45) cancer cells in vitro, and the sugar branches were indispensible for the cytotoxicity. Our work contributes to the first report of a novel cytotoxic polysaccharide from Flos A. manihot that may provide a potential source of anti-tumor agent.

Effect and Molecular Mechanisms of Traditional Chinese Medicine on Regulating Tumor Immunosuppressive Microenvironment. BIOMED RESEARCH INTERNATIONAL 2015; 2015:261620.

Abstract
Traditional Chinese medicine (TCM) is an important complementary strategy for treating cancer in China. The mechanism is related to regulating the internal environment and remodeling the tumor immunosuppressive microenvironment (TIM). Herein we illustrate how TIM is reformed and its protumor activity on promoting tumor cell proliferation, angiogenesis and lymphangiogenesis, tumor invasion, and the oncogenicity of cancer stem cells. Furthermore we summarize the effects and mechanism of TCM on regulating TIM via enhancing antitumor immune responses (e.g., regulating the expression of MHC molecules and Fas/FasL, attenuating cancerigenic ability of cancer stem cells) and remolding immunosuppressive cells (e.g., reversing immune phenotypes of T lymphocytes and tumor associated macrophages, promoting dendritic cells mature, restraining myeloid derived suppressor cells function, and regulating Th1/Th2 factors). We also reveal the bidirectional and multitargeting functions of TCM on regulating TIM. Hopefully, it provides new theoretical basis for TCM clinical practice in cancer treatment and prevention.
