Abstract
As a complex ecosystem of the human body, the intestinal flora maintains a dynamic balance with the host and plays an irreplaceable role in life activities such as nutritional metabolism and host immunity. The intestinal flora interacts with polysaccharides, the intestinal flora digests non-digestible polysaccharides, and polysaccharides can be used as an important energy source for intestinal microorganisms. Disturbance of the gut microbiota (GM) leads to the occurrence of diseases, polysaccharides as prebiotics can improve the disease by regulating the composition of GM. In this paper, we reviewed the current knowledge about the relationship between polysaccharides, gut microbiota, and and human health, described the microbial composition of the human, the relationship between intestinal flora disorders and disease occurrence, and summarized the interactions between polysaccharides and intestinal microorganisms.

Summary The link between the gut microbiota and type 2 diabetes (T2D) warrants further investigation because of known confounding effects from antidiabetic treatment. Here, we profiled the gut microbiota in a discovery (n = 1,011) and validation (n = 484) cohort comprising Swedish subjects naive for diabetes treatment and grouped by glycemic status. We observed that overall gut microbiota composition was altered in groups with impaired glucose tolerance, combined glucose intolerance and T2D, but...

The gut microbiota is a complex microbial ecosystem that coexists with the human organism in the intestinal tract. The members of this ecosystem live together in a balance between them and the host, contributing to its healthy state. Stress, aging, and antibiotic therapies are the principal factors affecting the gut microbiota composition, breaking the mutualistic relationship among microbes and resulting in the overgrowth of potential pathogens. This condition, called dysbiosis, has been linked...

Abstract A novel polysaccharide, designated as MOP-3, was extracted and isolated from the leaves of Moringa oleifera. Structural characterization showed that MOP-3 had a molecular weight (MW) of 4.033 × 106 Da and was composed of arabinose, glucose and galactose with a molar ratio of 47.73:1.00:57.65. Methylation and nuclear magnetic resonance (NMR) analysis revealed that the main glycosidic linkage types of MOP-3 were (1→3,6)-β-D-Galp, (1→6)-β-D-Galp, (1→5)-α-L-Araf, and T-α-L-Araf. MOP-3 conta...

The gut microbiota (GM) is defined as the community of microorganisms (bacteria, archaea, fungi, viruses) colonizing the gastrointestinal tract. GM regulates various metabolic pathways in the host, including those involved in energy homeostasis, glucose and lipid metabolism, and bile acid metabolism. The relationship between alterations in intestinal microbiota and diseases associated with civilization is well documented. GM dysbiosis is involved in the pathogenesis of diverse diseases, such as ...

Abstract Intestine is not only the largest digestive and absorbing organ, but also an important defensive barrier of the body. Maintaining healthy intestinal barrier is a prerequisite for intestinal function. In this study, polysaccharides from the cultured Cordyceps sinensis (CSP) were orally given to cyclophosphamide (Cy)-treated mice to investigate its protective effect on intestinal barrier injury. Results showed that CSP had positive effects on intestinal morphology, including restoring vil...

Abstract Background As an important role of host homeostasis, the glycometabolism was closely related to the process and metabolic pathways of carbohydrates such as glycolysis, hexosamine biosynthetic pathway, and pentose phosphate in the host. Disorders of glycometabolism result in a series of metabolic diseases, such as diabetes, obesity, hypoglycemia, and etc. Scope and approach Polysaccharides, which were widely existing in daily diet and cannot be directly digested by gastrointestinal enzym...

Abstract Type 2 diabetes mellitus (T2DM) is a common clinical chronic disease, while its pathogenesis is still inconclusive. Intestinal flora, the largest micro-ecological system in the human body, is involved in, meanwhile has a major impact on the body's material and energy metabolism. Recent studies have shown that in addition to obesity, genetics, and islet dysfunction, the disturbance of intestinal flora may partly give rise to diabetes. In this paper, we summarized the current research on ...

Abstract A crude polysaccharide derived from Flammulina velutipes (FVP), mainly consisting of glucose linked with β-glycosidic bonds, was administered to 6 week-old male ICR mice by gavage for five weeks, to investigate the effects on mice intestinal microbiota and immune response. The pH of the intestinal compartments decreased while short chain fatty acids concentrations increased in FVP-fed groups, in a dose dependent manner. High throughput sequencing revealed the enrichment in the diversity...

Current scientific literature has identified the infant gut microbiota as a multifaceted organ influencing a range of aspects of host-health and development. Many scientific studies have focused on characterizing the main microbial taxa that constitute the resident bacterial population of the infant gut. This has generated a wealth of information on the bacterial composition of the infant gut microbiota, and on the functional role/s exerted by their key microbial members. In this context, one of...

Abstract null null Pharmacological and clinical studies have consistently demonstrated that polysaccharides exhibit great potential on immune regulation. Polysaccharides can interact directly or indirectly with the immune system, triggering cell-cell communication and molecular recognition, leading to immunostimulatory responses. Gut microbiota is adept at foraging polysaccharides as energy sources and confers benefits in the context of immunity and chronic autoimmune disease, such as multiple s...

Abstract null null This study investigated the effect of noni juice (NJ) addition on physico-chemical, sensory, and bioactive properties of yogurt. NJ addition increased the acidity, yogurt starter count, total phenolics, total flavonoids, antioxidant activity, and flavor of yogurt. However, it reduced the viscosity, syneresis, and color parameters. Furthermore, whether feeding yogurt with or without NJ (7%, v/v) (NY or Y) (20 g/kg of diet) could alter the response of mice to dextran sodium sulf...

Abstract null null The gastroprotective effects of polysaccharides had become a hot topic in the field of functional polysaccharides research. Three polysaccharides, namely HPS-80-1, HPS-80-2, and HPS-80-3 were purified by DEAE-52 column chromatography. The thermodynamic characteristics, scanning electron microscopy, and Congo red experimental results of the above polysaccharides were greatly distinctive. Then a mature GES-1 oxidative stress cell model induced by H2O2 was established to screen o...

Abstract null null This study aimed to explore the in vitro simulated digestion and fecal fermentation behaviors of two purified exopolysaccharide fractions (EPS1 and EPS2) from Paecilomyces cicadae TJJ1213 and its effects on human gut microbiota composition. Results showed that EPS1 and EPS2 could not be digested by saliva-gastrointestinal. After fecal fermentation, however, the molecular weight of EPS1 and EPS2 significantly decreased, and the molar ratios of the monosaccharide composition rem...

The fungus Sporidiobolus pararoseus not only produces carotenoids, but also produces bioactive extracellular polysaccharides (SPP). However, the relationship between SPP and the metabolism of gut microbiome is unclear. The aim of this study was to investigate the mechanism of SPP regulating intestinal health in vivo and in vitro. Results showed that SPP are nondigestible polysaccharides after the digestion with simulated stomach and small intestinal juice in vitro. After SPP was cultured in an i...

Inflammatory bowel disease (IBD) is a disease characterized by intestinal inflammation with immune dysregulation and intestinal microecological imbalance. In a dextran sulfate sodium salt (DSS)-induced IBD mouse model, noni (Morinda citrifolia L.) fruit polysaccharides (NFP) with homogalacturonan and rhamnogalacturonan-I domain decreased the concentration of serum LPS, TNF-α, and IL-17 by 84, 42, and 65%, respectively. It was abolished when intestinal microbiota were depleted by antibiotics. Seq...
