RESUMEN

Nutraceutical immune support offers potential for designing blends with complementary mechanisms of action for robust support of innate immune alertness. We documented enhanced immune activation when bovine colostrum peptides (BC-Pep) were added to an immune blend (IB) containing ß-glucans from yeast, shiitake, maitake, and botanical non-ß-glucan polysaccharides. Human peripheral blood mononuclear cells (PBMCs) were cultured with IB, BC-Pep, and IB + BC-Pep for 20 h, whereafter expression of the activation marker CD69 was evaluated on NK cells, NKT cells, and T cells. Cytokine levels were tested in culture supernatants. PBMCs were co-cultured with K562 target cells to evaluate T cell-mediated cytotoxicity. IB + BC-Pep triggered highly significant increases in IL-1ß, IL-6, and TNF-α, above that of cultures treated with matching doses of either IB or BC-Pep. NK cell and T cell activation was increased by IB + BC-Pep, reaching levels of CD69 expression several fold higher than either BC-Pep or IB alone. IB + BC-Pep significantly increased T cell-mediated cytotoxic killing of K562 target cells. This synergistic effect suggests unique amplification of signal transduction of NK cells and T cells due to modulation of IB-induced signaling pathways by BC-Pep and is of interest for further pre-clinical and clinical testing of immune defense activity against virally infected and transformed cells.

RESUMEN

The Nerium oleander extract PBI 05204 (PBI) and its cardiac glycoside constituent oleandrin have direct anti-viral properties. Their effect on the immune system, however, is largely unknown. We used an in vitro model of human peripheral blood mononuclear cells to document effects under three different culture conditions: normal, challenged with the viral mimetic polyinosinic:polycytidylic acid Poly I:C, and inflamed by lipopolysaccharide (LPS). Cells were evaluated for immune activation marks CD69, CD25, and CD107a, and culture supernatants were tested for cytokines. Both PBI and oleandrin directly activated Natural Killer (NK) cells and monocytes and triggered increased production of cytokines. Under viral mimetic challenge, PBI and oleandrin enhanced the Poly I:C-mediated immune activation of monocytes and NK cells and enhanced production of IFN-γ. Under inflammatory conditions, many cytokines were controlled at similar levels as in cultures treated with PBI and oleandrin without inflammation. PBI triggered higher levels of some cytokines than oleandrin. Both products increased T cell cytotoxic attack on malignant target cells, strongest by PBI. The results show that PBI and oleandrin directly activate innate immune cells, enhance anti-viral immune responses through NK cell activation and IFN-γ levels, and modulate immune responses under inflamed conditions. The potential clinical impact of these activities is discussed.

RESUMEN

OBJECTIVES: To evaluate the effects of ATP 360, a nutraceutical energy formula, in people experiencing long-term fatigue affecting daily living. To explore the use of ex vivo mitochondrial stress testing to evaluate cellular energy improvements with nutraceutical support. STUDY DESIGN: An open-label study design was used with screening for long-term fatigue, scoring 50% or higher on the Piper Fatigue Scale. Eleven participants (8 women, 3 men) consumed the nutraceutical energy formula for 8 weeks, with a 1-week online evaluation and 4-week and 8-week follow-up visits. Eleven healthy people of similar age and BMI range donated blood for comparative evaluation of mitochondrial function in non-fatigued subjects. METHODS: Fatigue scoring was performed using the Piper Fatigue Scale. Other data included blood pressure readings and questionnaires for pain and wellness. Blood draws were performed. Serum was tested for cytokines using bead-based immunoassays. Leukocytes were tested for mitochondrial mass and mitochondrial membrane potential after 2-hour ex vivo inflammatory challenges with bacterial lipopolysaccharide using fluorescent probes, along with flow cytometry analysis. PRIMARY OUTCOME MEASURES: Change in fatigue and pain levels from baseline to 8 weeks. RESULTS: Reduction in long-term fatigue was rapid and highly significant after 1 week. Pain reduction reached statistical significance at 4 weeks. Wellness scores improved, especially mental functioning, sleep, increased emotional wellness, and increased energy/vitality. Diastolic blood pressure was reduced. Serum levels of TNF-α and interleukin 8 were reduced. At baseline, leukocyte mitochondrial responses to ex vivo inflammation were low compared to leukocytes from healthy non-fatigued people, showing a mild 21% increase after 4 weeks (not statistically significant), and returning to baseline at 8 weeks. CONCLUSION: This proof-of-concept study showed that consumption of a proprietary nutraceutical energy formula resulted in rapid and sustained fatigue reduction associated with reduced pain and inflammatory cytokines and improved wellness. A mild increase in mitochondrial response to inflammation was seen at 4 weeks. A future study with longer duration should evaluate whether mitochondrial function may approach that of a healthy population. TRIAL REGISTRATION: This study was conducted in accordance with the ethical standards set forth in the Helsinki Declaration of 1975 (trial registration number NCT04261881).

RESUMEN

BACKGROUND: The medicinal mushroom Trametes versicolor (Tv, Turkey Tail) is often prepared for consumption as a powder from the fungal mycelium and the fermented substrate on which it grew. The goal for this study was to evaluate the immune-modulating properties of the mycelium versus the fermented substrate, to document whether an important part of the immune-activating effects resides in the metabolically fermented substrate. METHODS: Tv mycelium was cultured on rice flour. The mycelium and the fermented substrate were mechanically separated, dried, and milled. The initial substrate served as a control. Aqueous fractions were extracted and passed through 0.22-µm filters. The remaining solids were passed through homogenization spin columns without filtration. The aqueous and solid fractions of the initial substrate (IS), the fermented substrate (FS), and the Trametes versicolor mycelium (TvM) were tested for immune-activating and modulating activities on human peripheral blood mononuclear cell cultures, to examine expression of the CD69 activation marker on lymphocytes versus monocytes, and on the T, NKT, and NK lymphocyte subsets. Culture supernatants were tested for cytokines using Luminex arrays. RESULTS: Both aqueous and solid fractions of TvM triggered robust induction of CD69 on lymphocytes and monocytes, whereas FS only triggered minor induction of CD69, and IS had no activating effect. The aqueous extract of TvM had stronger activating effects than the solid fraction. In contrast, the solid fraction of IS triggered a reduction in CD69, below levels on untreated cells. Both aqueous and solid fractions of FS triggered large and dose-dependent increases in immune-activating pro-inflammatory cytokines (IL-2, IL-6), anti-inflammatory cytokines Interleukin-1 receptor antagonist (IL-1ra) and Interleukin-10 (IL-10), anti-viral cytokines interferon-gamma (IFN-γ) and Macrophage Inflammatory Protein-alpha (MIP-1α), as well as Granulocyte-Colony Stimulating Factor (G-CSF) and Interleukin-8 (IL-8). TvM triggered more modest cytokine increases. The aqueous extract of IS showed no effects, whereas the solid fraction showed modest effects on induction of cytokines and growth factors. CONCLUSION: The results demonstrated that the immune-activating bioactivity of a mycelial-based medicinal mushroom preparation is a combination of the mycelium itself (including insoluble beta-glucans, and also water-soluble components), and the highly bioactive, metabolically fermented substrate, not present in the initial substrate.

RESUMEN

Highbush (cultivated) and lowbush (wild) are the two major blueberry species in the US market. Eight phenolic acids were detected and quantified from these two species by HPLC-MS. Chlorogenic acid was found to be the predominant phenolic acid in both species, with 0.44 mg/g fresh weight in lowbush blueberries and 0.13 mg/g fresh weight in highbush blueberries. Total phenolic content in lowbush blueberries is over three times higher than that of highbush blueberries. The phenolic acid mixtures representing those in the two species were prepared by using authentic standards to assess their contribution to total antioxidant and anti-inflammatory activities of the whole berries. Neither lowbush nor highbush blueberry phenolic acid mixture contributed significantly to the total antioxidant capacity of their relevant whole berries measured by oxygen radical absorbance capacity (ORAC). Both phenolic acid mixtures were able to enter the cell and showed in cell antioxidant activities from the cell based antioxidant protection of erythrocytes (CAP-e) assay. Lowbush blueberry phenolic acid mixture was found to show anti-inflammatory activities by inhibiting the nuclear factor-κB (NF-κB) activation and the production of inflammatory cytokines (TNF-α and IL-6) at the high dose.

RESUMEN

BACKGROUND: Polygonum minus Huds.is a culinary flavouring that is common in South East Asian cuisine and as a remedy for diverse maladies ranging from indigestion to poor eyesight. The leaves of this herb have been reported to be high in antioxidants. Flavonoids which have been associated with memory, cognition and protection against neurodegeneration were found in P. minus. METHOD: This study examined a P. minus aqueous extract (Lineminus™) for its antioxidant activity using the Oxygen Radical Absorbance Capacity (ORAC) assay, the ex vivo Cellular Antioxidant Protection of erythrocytes (CAP-e) assays and for potential anticholinesterase activity in vitro. Cognitive function and learning of Lineminus™ was evaluated using scopolamine induced cognition deficits in a Barnes maze, rodent model of cognition. RESULTS: The extract displayed in vitro antioxidant activity with a total ORAC value of 16,964 µmole TE/gram. Cellular antioxidant protection from free radical damage using the CAP-e assay, with an IC50 of 0.58 g/L for inhibition of cellular oxidative damage, was observed. The extract inhibited cholinesterase activity with an IC50 of 0.04 mg/ml with a maximum inhibition of 68%. In a rodent model of cognition using scopolamine induced cognition deficits in the Barnes maze, the extract attenuated scopolamine induced disruptions in learning at the higher dose of 100 mg/kg. CONCLUSION: These data shows that P. minus possesses antioxidant and anticholinesterase activity and demonstrated enhanced cognition in vivo. The data suggest neuroprotective properties of the extract.

RESUMEN

Bacterial biofilms are hardy, adaptable colonies, evading immune recognition while triggering and sustaining inflammation. The goals for this study were to present a method for testing the immunogenicity of secreted metabolites from pathogenic biofilm and to document whether biofilm treated with a nutraceutical enzyme and botanical blend (NEBB) showed evidence of reprogrammed bacterial metabolism, potentially becoming more recognizable to the immune system. We screened immune-modulating properties of metabolites from established biofilm from Pseudomonas aeruginosa (Pa), Stapholycoccus simulans (Ss), and Borrelia burgdorferi (Bb). Secreted metabolites significantly increased the cytokine production by human peripheral blood mononuclear cells, including Interleukin-1-beta (IL-1ß), Interleukin-6 (IL-6), macrophage inflammatory protein-1-alpha (MIP-1α), tumor necrosis factor-alpha (TNF-α), interleukin-1 receptor antagonist (IL-1ra), and interleukin-10 (IL-10). Pa metabolites triggered the most robust increase in IL-1ß, whereas Bb metabolites triggered the most robust increase in IL-10. NEBB-disrupted biofilm produced metabolites triggering altered immune modulation compared to metabolites from untreated biofilm. Metabolites from NEBB-disrupted biofilm triggered increased MIP-1α levels and reduced IL-10 levels, suggesting a reduced ability to suppress the recruitment of phagocytes compared to untreated biofilm. The results suggest that nutraceutical biofilm disruption offers strategies for inflammation management in chronic infectious illnesses. Further clinical studies are warranted to evaluate clinical correlations in infected human hosts.

RESUMEN

GOAL: To evaluate the acute impact of a nutraceutical blend on immune surveillance. STUDY DESIGN: A randomized, double-blind, placebo-controlled, cross-over trial was conducted in 11 healthy subjects. Blood samples were taken immediately before and at 1, 2, and 3 hours after consuming placebo or 500 mg of UP360, which is a blend of botanicals from Aloe vera, Poria cocos, and rosemary (APR extract). Immunophenotyping and flow cytometry quantified numbers of monocytes, NK cells, NKT cells, CD8+ cytotoxic T cells, γδT cells, and total T cells, and expression of CD25 and CD69 activation markers. Plasma was tested for cytokines, chemokines, growth factors, and enzymatic activity of superoxide dismutase and catalase. RESULTS: Compared to the placebo, consumption of APR extract triggered rapid increases in chemokine levels starting at 1 hour, including IP-10 (P<0.05) and MCP-1 (P<0.1), which peaked at 2 hours (P<0.01) and 3 hours (P<0.05), respectively. The stem cell-mobilizing growth factor G-CSF increased at 2 hours (P<0.05). Increased immune surveillance involved a transient effect for monocytes at 1 hour, followed by NKT cells, CD8+ cytotoxic T cells, and γδT cells at 2-3 hours. Increased immune cell alertness was seen at 1 hour by increased CD25 expression on monocytes (P<0.01), NKT cells (P<0.01), and T cells (P<0.05). NKT cells showed upregulation of CD69 at 2 hours (P<0.01). Increased enzymatic activity was seen at 2 hours for the antioxidant enzymes superoxide dismutase (P<0.05) and catalase (P<0.01). CONCLUSION: Consumption of APR extract triggered acute changes to chemokine levels. In addition, immune alertness was increased via the expression of activation markers on multiple types of innate immune cells, followed by increased immune surveillance and antioxidant protection. This suggests a beneficial enhancement of natural immune surveillance, likely via a combination of gut-mediated cytokine release and vagus nerve communication, in combination with cellular protection from oxidative stress.

RESUMEN

Microbial biofilms are resilient, immune-evasive, often antibiotic-resistant health challenges, and increasingly the target for research into novel therapeutic strategies. We evaluated the effects of a nutraceutical enzyme and botanical blend (NEBB) on established biofilm. Five microbial strains with known implications in chronic human illnesses were tested: Candida albicans, Staphylococcus aureus, Staphylococcus simulans (coagulase-negative, penicillin-resistant), Borrelia burgdorferi, and Pseudomonas aeruginosa. The strains were allowed to form biofilm in vitro. Biofilm cultures were treated with NEBB containing enzymes targeted at lipids, proteins, and sugars, also containing the mucolytic compound N-acetyl cysteine, along with antimicrobial extracts from cranberry, berberine, rosemary, and peppermint. The post-treatment biofilm mass was evaluated by crystal-violet staining, and metabolic activity was measured using the MTT assay. Average biofilm mass and metabolic activity for NEBB-treated biofilms were compared to the average of untreated control cultures. Treatment of established biofilm with NEBB resulted in biofilm-disruption, involving significant reductions in biofilm mass and metabolic activity for Candida and both Staphylococcus species. For B. burgdorferi, we observed reduced biofilm mass, but the remaining residual biofilm showed a mild increase in metabolic activity, suggesting a shift from metabolically quiescent, treatment-resistant persister forms of B. burgdorferi to a more active form, potentially more recognizable by the host immune system. For P. aeruginosa, low doses of NEBB significantly reduced biofilm mass and metabolic activity while higher doses of NEBB increased biofilm mass and metabolic activity. The results suggest that targeted nutraceutical support may help disrupt biofilm communities, offering new facets for integrative combinational treatment strategies.

RESUMEN

Spore-forming probiotic bacteria, including Bacillus coagulans, are resilient and produce a variety of beneficial metabolites. We evaluated the immune-modulating effects of the novel probiotic strain Bacillus coagulans JBI-YZ6.3, where the germinated spores, metabolite fraction, and cell wall fraction were tested in parallel using human peripheral blood mononuclear cell cultures under both normal and lipopolysaccharide-induced inflamed culture conditions. The expression of CD25 and CD69 activation markers was evaluated via flow cytometry. Supernatants were tested for cytokines, interferons, chemokines, and growth factors using Luminex arrays. The germinated spores were highly immunogenic; both the cell wall and metabolite fractions contributed significantly. Under normal culture conditions, increased levels of immune activation were observed as increased expressions of CD25 and CD69 relative to natural killer cells, suggesting an increased ability to attack virus-infected target cells. On monocytes, a complex effect was observed, where the expression of CD25 increased under normal conditions but decreased under inflamed conditions. This, in combination with increased interleukin-10 (IL-10) and decreased monocyte chemoattractant protein-1 (MCP-1) production under inflamed conditions, points to anti-inflammatory effects. The production of the stem cell-related growth factor granulocyte colony-stimulating Factor (G-CSF) was enhanced. Further research is warranted to characterize the composition of the postbiotic metabolite fraction and document the characteristics of immunomodulating agents secreted by this probiotic strain.

RESUMEN

OBJECTIVE: To evaluate acute effects of bovine colostrum low-molecular weight fraction (CLMWF) on selected aspects of innate immune function in healthy human subjects. METHODOLOGY: A placebo-controlled, double-blinded, randomized cross-over trial involving 12 healthy subjects, age 22-72, was conducted at NIS Labs during the year 2010. Placebo or 150 mg CLMWF was given orally. Blood was drawn immediately before and at 1 and 2h after consumption. RESULTS: A single dose of CLMWF, when compared to placebo, resulted in rapid increase in phagocytic activity of monocytes at 1h (P<0.12) and polymorphonuclear cells at 1h (P<0.08) and 2h (P<0.03) after consumption. Observations included increased numbers of CD3(+) T cells (P<0.05), and a transient reduction in circulating CD3(-)CD56(+) natural killer (NK) cells at 1h (P<0.04), returning to normal levels at 2h after consumption (P<0.96). The relative increase of NK cells from 1 to 2h after consumption was not associated with an increase in CD69 or CD25 activation markers, suggesting that new NK cells were mobilized into circulation. CONCLUSION: The increased phagocytic activity and rapid transient changes in NK cell numbers suggest that upon consumption, interaction of CLMWF with immune cells in the gut mucosa triggers immediate events with systemic consequences.

RESUMEN

OBJECTIVE: To evaluate anti-inflammatory properties of a nutraceutical blend containing L-ergothioneine in concert with other anti-inflammatory and analgesic ingredients, combined with nutritional cartilage support. METHODOLOGY: Twelve human subjects were tested over a 6-week period of product consumption followed by a 6-week wash-out period, conducted at NIS Labs during late fall/early winter 2010. Range of motion (ROM) assessment of joint motility was performed using JTECH dual digital inclinometry and included flexion, extension, and rotation through the vertical weight-bearing column (neck, thorax, lumbar, hip, knees) and shoulders. Pain evaluation included questionnaires and Visual Analogues Scales regarding primary and secondary pain complaints at rest and at use. RESULTS: ROM improvements were seen after 1 week, and further improved at 6 weeks (primary pain area P<0.2, secondary pain area P<0.03). Pain in primary and secondary areas at use was significantly reduced already at 1 week, compared to baseline (P<0.05). Pain reduction for both primary and secondary pain areas during use reached a high level of statistical significance at 6 weeks (P<0.004), and remained highly significant after the 6-week wash-out period. CONCLUSION: Pain reduction and improved ROM were observed during the 6-week consumption. Residual effects were seen 6 weeks after stopping consumption of the ergothioneine supplement.

RESUMEN

OBJECTIVE: To evaluate effects on the innate immune system after exposure to, a consumable low-molecular weight fraction (CLMWF) of immunoglobulin-depleted bovine colostrum whey. METHODOLOGY: Cell-based immune assays were performed in vitro, and host resistance towards bacterial and viral infection was evaluated in two mouse studies. RESULTS: In vitro data showed a multimodal effect, as CLMWF treatment resulted in a rapid increase in phagocytosis. CLMWF increased chemotaxis of polymorphonuclear cells towards the bacterial peptide f-MLP. CLMWF treatment of natural killer cells increased expression of the CD69 activation marker. Mononuclear phagocytes showed decreased numbers of CD14(bright) and increased number of CD14(dim) cells. The remaining CD14(bright) cells showed reduced expression of CD80 and CD86, whereas CD14(dim) cells showed increased expression of CD80 and CD86, suggesting dendritic cell maturation. Mouse models were applied to evaluate the immune-modulating capacity of CLMWF when consumed acutely during bacterial (Streptococcus) and viral (Influenza) infections in vivo. Reduced bacterial and viral loads were observed in lungs within 24h. Viral load was also reduced when CLMWF was introduced intranasally. CONCLUSION: The data suggest that the support of antimicrobial immune defense mechanisms and maturation of antigen-presenting cells in vitro translates to protection in vivo when product is introduced across mucosal membranes.

RESUMEN

A safety evaluation was performed for EpiCor, a product produced by a proprietary fermentation process using Saccharomyces cerevisiae. Studies included the following assays: bacterial reverse mutation, mouse lymphoma cell mutagenicity, mitogenicity assay in human peripheral lymphocytes, and a cytochrome P450 ([CYP] CYP1A2 and CYP3A4) induction assessment as well as 14-day acute, 90-day subchronic, and 1-year chronic oral toxicity studies in rats. No evidence of genotoxicity or mitogenicity was seen in any of the in vitro or in vivo studies. The CYP assessment showed no interactions or inductions. No toxic clinical symptoms or histopathological lesions were observed in the acute, subchronic, or chronic oral toxicity studies in the rat. Results of the studies performed indicate that EpiCor does not possess genotoxic activity and has a low order of toxicity that is well tolerated when administered orally. The no observable adverse effect level (NOAEL) was 1500 mg/kg body weight (bw)/d for the 90-day study and 800 mg/kg bw/d for the 1 year study, for the highest doses tested.

RESUMEN

BACKGROUND: This study was performed to evaluate anti-inflammatory and immune modulating properties of the probiotic, spore-forming bacterial strain: Bacillus coagulans: GBI-30, (PTA-6086, GanedenBC30TM). In addition, cell wall and metabolite fractions were assayed separately to address whether biological effects were due to cell wall components only, or whether secreted compounds from live bacteria had additional biological properties. The spores were heat-activated, and bacterial cultures were grown. The culture supernatant was harvested as a source of metabolites (MTB), and the bacteria were used to isolate cell wall fragments (CW). Both of these fractions were compared in a series of in vitro assays. RESULTS: Both MTB and CW inhibited spontaneous and oxidative stress-induced ROS formation in human PMN cells and increased the phagocytic activity of PMN cells in response to bacteria-like carboxylated fluorospheres. Both fractions supported random PMN and f-MLP-directed PMN cell migration, indicating a support of immune surveillance and antibacterial defense mechanisms. In contrast, low doses of both fractions inhibited PMN cell migration towards the inflammatory mediators IL-8 and LTB4. The anti-inflammatory activity was strongest for CW, where the PMN migration towards IL-8 was inhibited down to dilutions of 1010.Both MTB and CW induced the expression of the CD69 activation marker on human CD3- CD56+ NK cells, and enhanced the expression of CD107a when exposed to K562 tumor cells in vitro.The fractions directly modulated cytokine production, inducing production of the Th2 cytokines IL-4, IL-6, and IL-10, and inhibiting production of IL-2.Both fractions further modulated mitogen-induced cytokine production in the following manner: Both fractions enhanced the PHA-induced production of IL-6 and reduced the PHA-induced production of TNF-alpha. Both fractions enhanced the PWM-induced production of TNF-alpha and IFN-gamma. In addition, MTB also enhanced both the PHA- and the PWM-induced expression of IL-10. CONCLUSION: The data suggest that consumption of GanedenBC30TM may introduce both cell wall components and metabolites that modulate inflammatory processes in the gut. Both the cell wall and the supernatant possess strong immune modulating properties in vitro. The anti-inflammatory effects, combined with direct induction of IL-10, are of interest with respect to possible treatment of inflammatory bowel diseases as well as in support of a healthy immune system.

RESUMEN

OBJECTIVE: To evaluate the effects of daily consumption of Nopal cactus fruit juice (NFJ) on joint mobility in a population experiencing chronic pain but otherwise in good health. STUDY DESIGN: A double-blind, placebo-controlled study design was used to enroll 40 people after written informed consent, randomized to consume 3 oz/day of NFJ versus placebo. At baseline and 8 weeks, joint range of motion (ROM) was examined by digital inclinometry along the vertical weight-bearing axis of the body from neck to knees and the shoulders. Blood samples were tested for cytokines and C-reactive protein (CRP). Questionnaires addressed wellness, pain, and reliance on pain medications. RESULTS: After 8 weeks of consuming NFJ, participants showed improved ROM beyond that of participants consuming placebo. Cervical and thoracic/lumbar ROM for the NFJ group was significantly improved when compared to placebo (cervical: P<0.03, thoracic/lumbar: P<0.04). People consuming NFJ relied less on pain medication to complete daily activities (P<0.1) and experienced reduced interference from pain and breathing issues (not significant). Serum levels of Eotaxin, involved in airway inflammation, showed significant differences between placebo and NFJ groups after 8 weeks (P<0.048). Changes in CRP levels showed a larger reduction in the NFJ group (-13%) than in the placebo group (-4%) (not significant). In the subgroup with CRP levels between 1 and 9.9 mg/L at baseline, CRP levels decreased in the NFJ group (-30%) but increased in the placebo group (31%) (P<0.015). CONCLUSION: Consumption of NFJ for 8 weeks was associated with statistically significant improvements in joint mobility and physical functioning compared to the placebo group, allowing participants in the NFJ group to be more physically active; daily activities were easier, including walking, sitting, and lying. This was associated with reduced use of pain medication, possibly associated with anti-inflammatory properties of NFJ, as suggested by reduced Eotaxin and CRP levels.

RESUMEN

PURPOSE: To compare three fractions of a medicinal mushroom blend (MMB), MyCommunity, on immune-activation, inflammation-regulation, and induction of biomarkers involved in regenerative functions. METHODS: A seventeen-species MMB was sequentially extracted: first, saline solution at ambient temperature, followed by re-extraction of the solids in ethanol, and finally resuspension of the homogenized ethanol-insoluble solids in cell-culture media. Fractions were tested on peripheral blood mononuclear cells from three healthy donors. Immunostaining, flow-cytometry, and Luminex protein-arrays measured immune-cell activation and cytokine response. Dose-responses for induction of the CD69 early activation marker and individual cytokine and growth-factor responses for each donor were evaluated. The CD69 and the combined cytokine and growth-factor results were subjected to Non-metric Multidimensional Scaling (NMDS) and multivariate ordination to aid interpretation of the aggregate immune response and pairwise permutational MANOVA on a distance-matrix to evaluate statistical differences between treatments on pooled data from all donors. RESULTS: Differential effects were induced by water-soluble, ethanol-soluble, and insoluble immunomodulatory compounds of the MMB. The aqueous and ethanol fractions upregulated expression of CD69 on all tested cell types. Monocyte-activation was correlated with the ethanol fraction, while NKT and non-NK non-T cell-activation was more closely correlated with the aqueous fraction. The solid fraction was the most potent inducer of Tumor Necrosis Factor-α, as well as the anti-viral cytokines interferon-γ, MCP-1 (CCL-2), MIP-1α (CCL-3), and MIP-1ß (CCL-4), and induced G-CSF and b-FGF-growth-factors involved in regenerative functions-and the anti-inflammatory cytokine IL-1ra. CONCLUSION: The aqueous, ethanol, and insoluble compounds within MMB induced differential immune-activating, anti-inflammatory, and regenerative effects. This in vitro data suggests that, upon consumption, MMB may induce a concerted series of immunomodulatory events based on the differential solubility and bioavailability of the active constituents. These differential responses support both immune-activation and resolution of the host defense-induced inflammatory reactions, thus assisting a post-response return to homeostasis.

RESUMEN

Purpose: The objective for this clinical pilot study was to evaluate changes to chronic pain, vascular health, and inflammatory markers when consuming a dietary supplement blend (DSB, CytoQuel®), containing curcumin, resveratrol, tocotrienols, N-Acetylcysteine, and epigallocatechin gallate. Materials and methods: An open-label study design was used where 21 study participants were evaluated at baseline and at 2 and 8 weeks after consuming DSB. Participants were randomized to consume 3 capsules once daily versus 2 capsules twice daily. Pain and activities of daily living questionnaires were used to gather subjective data on pain levels and interference with daily living. Blood pressure was measured in both arms and ankles, and the ankle-brachial index (ABI) calculated. Blood samples were used to evaluate markers associated with inflammation and cardiovascular health. Results: Highly significant reduction of chronic pain was seen after 8 weeks (p<0.01), both at rest and when physically active. Faster improvement was seen when consuming 3 capsules once daily, compared to 2 capsules twice daily. The pain reduction resulted in improved sleep quality (p<0.1), and improved social functioning (p<0.01), and less need for support from others (p<0.05), Normalization of mildly elevated ABI at study start was seen after 2 weeks. Plasma fibrinogen and von Willebrand Factor and serum matrix metalloproteinase-9 (MMP-9) showed reduction after 2 weeks (not significant), whereas a reduction in serum interleukin-1 receptor antagonist-a (IL-1ra) was statistically significant after 2 weeks (p<0.05). Correlation between pain reduction and changes to MMP-9 after 8 weeks was highly significant (P<0.01), whereas correlation between pain reduction and changes to IL-1ra reached significance at 2 weeks for the group consuming 3 caps once daily (p<0.04). Conclusion: Consuming DSB helped manage pain, increased comfort during daily activities, and improved vascular function. This was associated with selective effects on specific blood biomarkers associated with inflammation and vascular health.

RESUMEN

PURPOSE: The aim of this study was to evaluate the effects of a proanthocyanidin-rich extract of sea buckthorn berry (SBB-PE) on the numbers of various types of adult stem cells in the blood circulation of healthy human subjects. STUDY DESIGN AND METHODS: A randomized, double-blind, placebo-controlled, cross-over trial was conducted in 12 healthy subjects. Blood samples were taken immediately before and at 1 and 2 hours after consuming either placebo or 500 mg SBB-PE. Whole blood was used for immunophenotyping and flow cytometry to quantify the numbers of CD45dim CD34+ CD309+ and CD45dim CD34+ CD309- stem cells, CD45- CD31+ CD309+ endothelial stem cells, and CD45- CD90+ mesenchymal stem cells. RESULTS: Consumption of SBB-PE was associated with a rapid and highly selective mobilization of CD45dim CD34+ CD309- progenitor stem cells, CD45- CD31+ CD309+ endothelial stem cells, and CD45- CD90+ lymphocytoid mesenchymal stem cells. In contrast, only minor effects were seen for CD45dim CD34+ CD309+ pluripotential stem cells. CONCLUSION: Consumption of SBB-PE resulted in selective mobilization of stem cell types involved in regenerative and reparative functions. These data may contribute to the understanding of the traditional uses of SBB for preventive health, regenerative health, and postponing the aging process.

RESUMEN

PURPOSE: The purpose of this work was to determine the pro-and anti-inflammatory properties of the single-cell organism Euglena gracilis (EG) and various fractions of its whole biomass. METHODS: Heterotrophically grown EG was tested, along with its aqueous fraction (E-AQ), the intact linear ß-glucan paramylon granules (PAR), and alkaline-solubilized paramylon. Peripheral blood mononuclear cell cultures were treated with the test products and analyzed for a variety of cellular responses. Immune cell activation was evaluated by flow cytometry detection of CD69 levels on CD3-CD56+ NK cells, CD3+CD56+ NKT cells, and monocytes, and cytokines were analyzed from the cell culture supernatants. Antioxidant capacity was measured by Folin-Ciocalteu assay and cellular antioxidant protection and MTT assays. RESULTS: EG and E-AQ were the most effective in driving immune cell responses as measured by CD69 upregulation on NK and NKT cells and proinflammatory (tumor necrosis factor, IL-6, IL-1ß) cytokine production. None of the test products effectively stimulated monocyte. EG and PAR inhibited reactive oxygen species under conditions of oxidative stress. E-AQ contained antioxidants capable of providing cellular antioxidant protection from oxidative damage and protection of mitochondrial function under inflammatory conditions. CONCLUSION: The effects of EG on immune function are only partially attributable to the content of the ß-glucan, paramylon. The regulation of additional cellular responses, such a reactive oxygen species production and resistance to oxidative stress, is likely mediated by currently unknown molecules found in the EG cell.
