Nutr Res Pract 2024; 18:33-45. [PMID: 38352207 PMCID: PMC10861340 DOI: 10.4162/nrp.2024.18.1.33] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2023] [Revised: 12/22/2023] [Accepted: 01/04/2024] [Indexed: 02/16/2024] Open
Abstract
BACKGROUND/OBJECTIVES Onion, particularly onion peel, is a quercetin-rich food with, anti-inflammatory and immunomodulatory effects. However, the effect of onion peel extract (OPE) in humans is unclear. Thus, the present study aimed to investigate whether OPE improves natural killer (NK) cell activity and cytokine concentration in a randomized double-blind placebo-controlled trial. SUBJECTS/METHODS Eighty participants aged 19-64 yrs old with a white blood cell count of 4,000-10,000 cells/µL, symptoms of upper respiratory infection at least once within the previous 12 mon, and perceived stress scale (PSS) over 14 were included. Participants were randomly assigned to take either 1,000 mg/day OPE or a placebo for 8 weeks. RESULTS Compliance were 87.4 ± 8.6% and 86.9 ± 79.0% in OPE and placebo groups. Compared to the placebo, OPE supplementation improved "Hoarseness" (P = 0.038) of the Wisconsin Upper Respiratory Symptom Survey (WURSS)-21 symptom, and stress scores (P = 0.001; 0.021) of PSS. Supplementation of OPE had no significant effect on NK cell activity and concentrations of cytokines such as interleukin (IL)-2, IL-6, IL-12, IL-1β, interferon-γ, and tumor necrosis factor-α. At baseline, the WURSS-21 symptom and PSS score (P = 0.024; 0.026) were higher in the OPE group than the placebo group. Among participants with higher than median WURSS-21 symptom score, OPE supplementation increased NK cell activity (P = 0.038). Supplementation of OPE had no significant effects on safety measurements and adverse events. CONCLUSIONS The present study suggested that OPE supplementation improves NK cell activity in participants with moderate upper respiratory symptoms without any significant adverse effects. Trial Registration ClinicalTrials.gov Identifier: NCT05666752.

Abstract
Euglena gracilis (Euglena) is a microalgae found in most freshwater environments that produces paramylon, an insoluble β-1,3-glucan linked to human immunity. We hypothesized that Euglena powder has effects on immune function in apparently healthy adults. The study included male or female volunteers between the ages of 20 and 70 years who had white blood cell counts ranging from 4 × 103/µL to 10 × 103/µL, a "severe" rating on the stress questionnaire from the Korea National Health and Nutrition Examination Survey, and at least 2 upper respiratory infections with cold-like symptoms in the previous year. Participants received either a placebo or 700 mg of Euglena powder daily for 8 weeks. The study measured natural killer cell activity, cytokine concentrations, and blood lipid profiles to confirm the immune effect of Euglena consumption. In conclusion, Euglena improved immunological function through natural killer cell activity. Safety assessment showed no significant changes in vital signs or clinical chemistry indicators, and there were no adverse events associated with Euglena consumption. Euglena supplementation may help boost the immune systems of healthy individuals.

Oral administration of Euglena gracilis paramylon ameliorates chemotherapy-induced leukocytopenia and gut dysbiosis in mice. Int J Biol Macromol 2022; 211:47-56.

Abstract
Euglena gracilis (EUG) is a food supplement rich in beta-glucans, which are stored in the form of granules called paramylon. We determined whether EUG improved chemotherapy-induced leukocytopenia and dysbiosis. Mice were orally administered EUG prior to gemcitabine treatment. Analyses of the blood cell count, leukocyte population in the spleen, granulocyte/macrophage-colony-stimulating factor (GM-CSF) production by splenocytes, and fecal microbiome were conducted. The recovery of total leukocytes, neutrophils, and monocytes was accelerated after a single gemcitabine treatment. A more rapid lymphocyte recovery rate was observed after four gemcitabine treatments. No difference was observed in the percentage of T, B, or myeloid cells or in the expression of Dectin-1 in the spleens of the gemcitabine and EUG/gemcitabine groups. The EUG/gemcitabine group showed an enhanced GM-CSF production by lipopolysaccharides-stimulated splenocytes. Next-generation sequencing revealed that gemcitabine-induced dysbiosis was alleviated. This study demonstrated that EUG-derived beta-glucans could act as a biological response modifier as well as prebiotics for ameliorating chemotherapy-induced adverse effects.

Enhancing of Wound Healing in Burn Patients through Candida albicans β-Glucan. J Fungi (Basel) 2022; 8:jof8030263. [PMID: 35330265 PMCID: PMC8949177 DOI: 10.3390/jof8030263] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2022] [Revised: 02/28/2022] [Accepted: 03/02/2022] [Indexed: 12/01/2022] Open
Abstract
The mortality and disability-adjusted life years (DALYs) of burn patients are decreasing over time. However, finding novel effective treatment approaches using natural agents is highly considered to reduce the burden of burn injuries. One of the recent agents used in wound healing is β-glucan, mainly extracted from fungi cell walls. This study aimed to evaluate the effect of 5% (m/m) of yeast β-glucan ointment on burn wound healing and to assess the impact of β-glucan on cytokines during the treatment. Thirty-three patients with second or third-degree burns were enrolled in this study. Two groups of twenty-three and ten patients used yeast 5% (m/m) β-glucan ointment (study group) and Stratamed ointment (control), respectively, on a daily basis, for a maximum of four weeks. The size of the burn wounds was measured before and at the end of the treatment. Blood samples of 14 and 10 patients in the β-glucan and control groups, respectively, were obtained before and after the treatment, and the enzyme-linked immunosorbent assay (ELISA) was performed to measure the serum concentration of the IL-4, IL-17, and IFN-γ cytokines. The log-binomial model was used to assess the efficacy of the β-glucan ointment on burn wound healing. ANOVA/ANCOVA was employed to assess the effects of β-glucan on the serum concentration of cytokines. After adjusting for potential confounders/covariates, patients receiving β-glucan had better wound healing (RR = 4.34; 95% CI: 0.73 to 25.67; p = 0.11). There was a significant difference in IL-4 secretion between the β-glucan and control groups after adjusting for potential confounders/covariates (MD = 77.27; 95% CI: 44.73 to 109.82; Cohen’s d = 2.21; 95% CI: 1.16 to 3.24; p = 0.0001). The results indicate that 5% (m/m) of β-glucan has efficacy in burn wound healing, and a significant difference was found in the level of IL-4 after receiving β-glucan. Further studies with a two-arm design and long-term use of ointment are needed to confirm the effect of β-glucan on wound healing and cytokine secretion.

Abstract
In this study, the effects of the immune stimulator Euglena gracilis (Euglena) in cyclophosphamide (CCP)-induced immunocompromised mice were assessed. The key component β-1,3-glucan (paramylon) constitutes 50% of E. gracilis. Mice were orally administered Euglena powder (250 and 500 mg/kg body weight (B.W.)) or β-glucan powder (250 mg/kg B.W.) for 19 days. In a preliminary immunology experiment, ICR mice were intraperitoneally injected with 80 mg of CCP/kg B.W. during the final 3 consecutive days. In the main experiment, BALB/c mice were treated with CCP for the final 5 days. To evaluate the enhancing effects of Euglena on the immune system, mouse B.W., the spleen index, natural killer (NK) cell activity and mRNA expression in splenocytes lungs and livers were determined. To detect cytokine and receptor expression, splenocytes were treated with 5 μg/ml concanavalin A or 1 μg/ml lipopolysaccharide. The B.W. and spleen index were significantly increased and NK cell activity was slightly enhanced in all the experimental groups compared to the CCP group. In splenocytes, the gene expression levels of tumor necrosis factor-α, interferon-γ, interleukin (IL)-10, IL-6, and IL-12 receptor were increased in the E. gracilis and β-glucan groups compared to the CCP group, but there was no significant difference. Treatment with 500mg of Euglena/kg B.W. significantly upregulated dectin-1 mRNA expression in the lung and liver compared to the CCP group. These results suggest that Euglena may enhance the immune system by strengthening innate immunity through immunosuppression.

Abstract
Objective: The purpose of this study was to determine if Porphyra tenera extract (PTE) has immune-enhancing effects and is safe in healthy adults. Methods: Subjects who met the inclusion criteria (3 × 103 ≤ peripheral blood leukocyte level ≥ 8 × 103 cells/µL) were recruited for this study. Enrolled subjects (n = 120) were randomly assigned to either the PTE group (n = 60) and were given 2.5 g/day of PTE (as PTE) in capsule form or the placebo group (n = 60) and were given crystal cellulose capsules with the identical appearance, weight, and flavor as the PTE capsules for 8 weeks. Outcomes were assessed based on measuring natural killer (NK) cell activity, cytokines level, and upper respiratory infection (URI), and safety parameters were assessed at baseline and 8 weeks. Results: Compared with baseline, NK cell activity (%) increased for all effector cell-to-target cell ratios in the PTE group after 8 weeks; however, changes were not observed in the placebo group (p < 0.10). Subgroup analysis of 101 subjects without URI showed that NK cell activity in the PTE group tended to increase for all effector cell/target cell (E:T) ratios (E:T = 12.5:1 p = 0.068; E:T = 25:1 p = 0.036; E:T = 50:1 p = 0.081) compared with the placebo group. A significant difference between the two groups was observed for the E:T = 25:1 ratio, which increased from 20.3 ± 12.0% at baseline to 23.2 ± 12.4% after 8 weeks in the PTE group (p = 0.036). A significant difference was not observed in cytokine between the two groups. Conclusion: PTE supplementation appears to enhance immune function by improving NK cell activity without adverse effects in healthy adults.

Abstract
INTRODUCTION Adoptive T-cell treatments of solid cancers have evolved into a robust therapy with objective response rates surpassing those of standardized treatments. Unfortunately, only a limited fraction of patients shows durable responses, which is considered to be due to a T cell-suppressive tumor microenvironment (TME). Here we argue that naturally occurring β-glucans can enable reversion of such T cell suppression by engaging innate immune cells and enhancing numbers and function of lymphocyte effectors. AREAS COVERED This review summarizes timely reports with respect to absorption, trafficking and immune stimulatory effects of β-glucans, particularly in relation to innate immune cells. Furthermore, we list effects toward well-being and immune functions in healthy subjects as well as cancer patients treated with orally administered β-glucans, extended with effects of β-glucan treatments in mouse cancer models. EXPERT OPINION Beta-glucans, when present in food and following uptake in the proximal gut, stimulate immune cells present in gut-associated lymphoid tissue and initiate highly conserved pro-inflammatory pathways. When tested in mouse cancer models, β-glucans result in better control of tumor growth and shift the TME toward a T cell-sensitive environment. Along these lines, we advocate that intake of β-glucans provides an accessible and immune-potentiating adjuvant when combined with adoptive T-cell treatments of cancer.

Abstract
Beta-glucans, homopolysaccharides composed of 3,6-branching β-(1→3)-D-glucan chains, attract great interest as inducers of cytokine synthesis. In this work, we studied the ability of linear fragments of beta-glucan chains to activate cytokine synthesis. Synthetic nona-β-(1→3)-D-glucoside (SO) representing a linear fragment of beta-glucan chain, endotoxin (ED), and natural β-(1→3)-D-glucan (GL) were tested for their role as inducers of cytokines in whole peripheral blood cultures collected from 17 individuals. The concentrations of IL-12p70, IFN-γ, IL-2, IL-10, IL-8, IL-6, IL-4, IL-5, IL-1β, TNF-α, and TNF-β were measured in the supernatants after 2, 24, and 48 h of cell culturing. SO, ED, and GL stimulated production of pro-inflammatory IFN-γ, IL-1β, IL-2, IL-6, IL-8, TNF-α and anti-inflammatory IL-10. The highest levels of biosynthesis after stimulation with SO were registered for IL-6, IL-8, and TNF-α. SO stimulated production of all cytokines (except IFN-γ) to a lesser extent than ED and GL. The IFN-γ/IL-10 (Th1/Th2) ratios after 24 and 48 h of culturing were 3.1 and 7.5 for SO; 0.03 and 0.1 for GL; and 0.06 and 0.2 for ED, respectively. The results indicate that linear fragments of beta-glucans cause a more pronounced shift of immune response towards the pro-inflammatory (Th1) type than beta-glucan itself.
