Finnegan D, Tocmo R, Loscher C. Targeted Application of Functional Foods as Immune Fitness Boosters in the Defense against Viral Infection. Nutrients 2023; 15:3371. [PMID: 37571308 PMCID: PMC10421353 DOI: 10.3390/nu15153371] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2023] [Revised: 07/26/2023] [Accepted: 07/27/2023] [Indexed: 08/13/2023] Open
Abstract
In recent times, the emergence of viral infections, including the SARS-CoV-2 virus, the monkeypox virus, and, most recently, the Langya virus, has highlighted the devastating effects of viral infection on human life. There has been significant progress in the development of efficacious vaccines for the prevention and control of viruses; however, the high rates of viral mutation and transmission necessitate the need for novel methods of control, management, and prevention. In recent years, there has been a shift in public awareness on health and wellbeing, with consumers making significant dietary changes to improve their immunity and overall health. This rising health awareness is driving a global increase in the consumption of functional foods. This review delves into the benefits of functional foods as potential natural means to modulate the host immune system to enhance defense against viral infections. We provide an overview of the functional food market in Europe and discuss the benefits of enhancing immune fitness in high-risk groups, including the elderly, those with obesity, and people with underlying chronic conditions. We also discuss the immunomodulatory mechanisms of key functional foods, including dairy proteins and hydrolysates, plant-based functional foods, fermentates, and foods enriched with vitamin D, zinc, and selenium. Our findings reveal four key immunity boosting mechanisms by functional foods, including inhibition of viral proliferation and binding to host cells, modulation of the innate immune response in macrophages and dendritic cells, enhancement of specific immune responses in T cells and B cells, and promotion of the intestinal barrier function. Overall, this review demonstrates that diet-derived nutrients and functional foods show immense potential to boost viral immunity in high-risk individuals and can be an important approach to improving overall immune health.

Synthesis and characterization of selenium nanoparticles stabilized with cocamidopropyl betaine. Sci Rep 2022; 12:21975. [PMID: 36539549 PMCID: PMC9763805 DOI: 10.1038/s41598-022-25884-x] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2022] [Accepted: 12/06/2022] [Indexed: 12/24/2022] Open
Abstract
In this work, selenium nanoparticles (Se NPs) stabilized with cocamidopropyl betaine were synthesized for the first time. It was observed that Se NPs synthesized in excess of selenic acid had a negative charge with ζ-potential of -21.86 mV, and in excess of cocamidopropyl betaine-a positive charge with ξ = + 22.71 mV. The resulting Se NPs with positive and negative charges had a spherical shape with an average size of about 20-30 nm and 40-50 nm, respectively. According to the data of TEM, HAADF-TEM using EDS, IR spectroscopy and quantum chemical modeling, positively charged selenium nanoparticles have a cocamidopropylbetaine shell while the potential- forming layer of negatively charged selenium nanoparticles is formed by SeO32- ions. The influence of various ions on the sol stability of Se NPs showed that SO42- and PO43- ions had an effect on the positive Se NPs, and Ba2+ and Fe3+ ions had an effect on negative Se NPs, which corresponded with the Schulze-Hardy rule. The mechanism of coagulating action of various ions on positive and negative Se NPs was also presented. Also, influence of the active acidity of the medium on the stability of Se NPs solutions was investigated. Positive and negative sols of Se NPs had high levels of stability in the considered range of active acidity of the medium in the range of 1.21-11.98. Stability of synthesized Se NPs stability has been confirmed in real system (liquid soap). An experiment with the addition of Se NPs stabilized with cocamidopropyl betaine to liquid soap showed that the particles of dispersed phases retain their initial distributions, which revealed the stability of synthesized Se NPs.

Abstract
Objective Trace elements deficiency is common among end-stage renal disease (ESRD) patients due to excessive loss during dialysis and the lower intake secondary to loss of appetite. Selenium (Se) is a trace element that plays an important role in the radical scavenging system and helps the body defend against oxidative stress. This study aims to evaluate the effects of Se supplementation on lipid profile, anemia, and inflammation indices in ESRD patients. Methods Fifty-nine hemodialysis patients enrolled and were randomly divided into two groups. Two hundred microgram Se capsules once daily for the case group and matching placebo for the control group were administered for three months. Demographic data were collected at the study beginning. Uric acid (UA), anemia and inflammation indices, and lipid profiles were recorded at the beginning and the end of the study. Findings UA and UA-to-HDL (high-density lipoprotein) ratio decreased significantly in the case group (P < 0.001). The changes in lipid profile were not significant among both groups. Hemoglobin slightly increased in the case group, however, it decreased significantly in the control group (P = 0.031). High-sensitivity C-reactive protein (hs-CRP) decreased in the case group and increased in the control group, however, none of these changes were significant. Conclusion According to the results of this study, selenium supplementation in ESRD patients could reduce some risk factors related to their mortality, such as the ratio of uric acid to HDL. However, the changes related to lipid profile, hemoglobin level and hs-CRP biomarker were not significant.

Abstract
Background: The potential role of selenium in preventing chronic liver diseases remains controversial. This meta-analysis aimed to summarize the available evidence from observational studies and intervention trials that had evaluated the associations between body selenium status and chronic liver diseases. Methods: We comprehensively searched MEDLINE, Embase, Web of Science, and Cochrane Library from inception to April 2021. The study protocol was registered at PROSPERO (CRD42020210144). Relative risks (RR) for the highest versus the lowest level of selenium and standard mean differences (SMD) with 95% confidence intervals (CI) were pooled using random-effects models. Heterogeneity and publication bias were evaluated using the I2 statistic and Egger’s regression test, respectively. Results: There were 50 studies with 9875 cases and 12975 population controls in the final analysis. Patients with hepatitis (SMD = −1.78, 95% CI: −2.22 to −1.34), liver cirrhosis (SMD = −2.06, 95% CI: −2.48 to −1.63), and liver cancer (SMD = −2.71, 95% CI: −3.31 to −2.11) had significantly lower selenium levels than controls, whereas there was no significant difference in patients with fatty liver diseases (SMD = 1.06, 95% CI: −1.78 to 3.89). Moreover, the meta-analysis showed that a higher selenium level was significantly associated with a 41% decrease in the incidence of significant advanced chronic liver diseases (RR = 0.59, 95% CI: 0.49 to 0.72). Conclusion: Our meta-analysis suggested that both body selenium status and selenium intake were negatively associated with hepatitis, cirrhosis, and liver cancer. However, the associations for fatty liver diseases were conflicting and need to be established in prospective trials.

Abstract
OBJECTIVE The aim: To evaluate the content of trace elements Zn, Cu and Se in blood serum and their relationship with viral load and the degree of liver fibrosis according to the results of the FibroMax test in patients with CHC. PATIENTS AND METHODS Materials and methods: 62 outpatients with a verified diagnosis of CHC were under observation, in which serum Zn, Cu and Se levels, viral load and degree of liver fibrosis were determined according to the FibroMax test. RESULTS Results: HCV 1b genotype was detected in all patients. The proportion of patients with a high viral load was 32%, with a low viral load - 68%. In 19% of patients, the level of Zn was below normal, and the levels of Cu and Se were within the reference values. The proportion of patients without fibrosis was 32%, 16% had minimal fibrosis, 40% had moderate fibrosis, 8% had progressive fibrosis, and 3% had severe fibrosis. 68% of patients had active inflammation of various degrees, liver steatosis - 65%, non-alcoholic steatohepatitis - 48%, inflammation caused by alcohol consumption was absent. No statistically significant difference was found in serum trace element levels and viral load (p>0.05). A weak negative correlation between the level of Zn and the degree of fibrosis (ρ=-0.340, p=0.007) and a negligible negative correlation between the level of Zn and inflammation activity (ρ=-0.286, p=0.024) were revealed. Patients with fibrosis grade ≥F2 had lower Zn levels compared to patients with fibrosis ≤F1 (0.607 (0.540, 0.691) mg/l vs. 0.716 (0.593, 0.875) mg/l, p=0.01), and when comparing there was no difference in Cu and Se levels (р>0.05). CONCLUSION Conclusions: Thus, there is a relationship between the level of Zn in blood serum and the degree of liver damage in patients with CHC, which indicates the prospects for further research.

Abstract
Viral infections have afflicted human health and despite great advancements in scientific knowledge and technologies, continue to affect our society today. The current coronavirus (COVID-19) pandemic has put a spotlight on the need to review the evidence on the impact of nutritional strategies to maintain a healthy immune system, particularly in instances where there are limited therapeutic treatments. Selenium, an essential trace element in humans, has a long history of lowering the occurrence and severity of viral infections. Much of the benefits derived from selenium are due to its incorporation into selenocysteine, an important component of proteins known as selenoproteins. Viral infections are associated with an increase in reactive oxygen species and may result in oxidative stress. Studies suggest that selenium deficiency alters immune response and viral infection by increasing oxidative stress and the rate of mutations in the viral genome, leading to an increase in pathogenicity and damage to the host. This review examines viral infections, including the novel SARS-CoV-2, in the context of selenium, in order to inform potential nutritional strategies to maintain a healthy immune system.

Abstract
Essential trace elements play crucial roles in the maintenance of health, since they are involved in many metabolic pathways. A deficiency or an excess of some trace elements, including zinc, selenium, iron, and copper, frequently causes these metabolic disorders such as impaired glucose tolerance and dyslipidemia. The liver largely regulates most of the metabolism of trace elements, and accordingly, an impairment of liver functions can result in numerous metabolic disorders. The administration or depletion of these trace elements can improve such metabolic disorders and liver dysfunction. Recent advances in molecular biological techniques have helped to elucidate the putative mechanisms by which liver disorders evoke metabolic abnormalities that are due to deficiencies or excesses of these trace elements. A genome-wide association study revealed that a genetic polymorphism affected the metabolism of a specific trace element. Gut dysbiosis was also responsible for impairment of the metabolism of a trace element. This review focuses on the current trends of four trace elements in chronic liver diseases, including chronic hepatitis, liver cirrhosis, nonalcoholic fatty liver disease, and autoimmune liver diseases. The novel mechanisms by which the trace elements participated in the pathogenesis of the chronic liver diseases are also mentioned.

Abstract
The trace element selenium is an essential micronutrient that plays an important role in maintaining homeostasis of several tissues including the immune system of mammals. The vast majority of the biological functions of selenium are mediated via selenoproteins, proteins which incorporate the selenium-containing amino acid selenocysteine. Several bacterial infections of humans and animals are associated with decreased levels of selenium in the blood and an adjunct therapy with selenium often leads to favorable outcomes. Many pathogenic bacteria are also capable of synthesizing selenocysteine suggesting that selenoproteins may have a role in bacterial physiology. Interestingly, the composition of host microbiota is also regulated by dietary selenium levels. Therefore, bacterial pathogens, microbiome, and host immune cells may be competing for a limited supply of selenium. Elucidating how selenium, in particular selenoproteins, may regulate pathogen virulence, microbiome diversity, and host immune response during a bacterial infection is critical for clinical management of infectious diseases.

Abstract
Reactive oxygen species (ROS) are frequently produced during viral infections. Generation of these ROS can be both beneficial and detrimental for many cellular functions. When overwhelming the antioxidant defense system, the excess of ROS induces oxidative stress. Viral infections lead to diseases characterized by a broad spectrum of clinical symptoms, with oxidative stress being one of their hallmarks. In many cases, ROS can, in turn, enhance viral replication leading to an amplification loop. Another important parameter for viral replication and pathogenicity is the nutritional status of the host. Viral infection simultaneously increases the demand for micronutrients and causes their loss, which leads to a deficiency that can be compensated by micronutrient supplementation. Among the nutrients implicated in viral infection, selenium (Se) has an important role in antioxidant defense, redox signaling and redox homeostasis. Most of biological activities of selenium is performed through its incorporation as a rare amino acid selenocysteine in the essential family of selenoproteins. Selenium deficiency, which is the main regulator of selenoprotein expression, has been associated with the pathogenicity of several viruses. In addition, several selenoprotein members, including glutathione peroxidases (GPX), thioredoxin reductases (TXNRD) seemed important in different models of viral replication. Finally, the formal identification of viral selenoproteins in the genome of molluscum contagiosum and fowlpox viruses demonstrated the importance of selenoproteins in viral cycle.

[PMID: 31212984 PMCID: PMC6627053 DOI: 10.3390/cells8060603] [Citation(s) in RCA: 31] [Impact Index Per Article: 6.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2019] [Accepted: 06/13/2019] [Indexed: 12/13/2022] Open
Abstract
Micronutrient deficiencies develop for a variety of reasons, whether geographic, socioeconomic, nutritional, or as a result of disease pathologies such as chronic viral infection. As micronutrients are essential for a strong immune response, deficiencies can significantly dampen both the innate and the adaptive arms of antiviral immunity. The innate immune response in particular is crucial to protect against hepatitis C virus (HCV), a hepatotropic virus that maintains chronic infection in up to 80% of individuals if left untreated. While many micronutrients are required for HCV replication, an overlapping group of micronutrients are also necessary to enact a potent immune response. As the liver is responsible for the storage and metabolism of many micronutrients, HCV persistence can influence the micronutrients' steady state to benefit viral persistence both directly and by weakening the antiviral response. This review will focus on common micronutrients such as zinc, iron, copper, selenium, vitamin A, vitamin B12, vitamin D and vitamin E. We will explore their role in the pathogenesis of HCV infection and in the response to antiviral therapy. While chronic hepatitis C virus infection drives deficiencies in micronutrients such as zinc, selenium, vitamin A and B12, it also stimulates copper and iron excess; these micronutrients influence antioxidant, inflammatory and immune responses to HCV.

Selenoprotein S silencing triggers mouse hepatoma cells apoptosis and necrosis involving in intracellular calcium imbalance and ROS-mPTP-ATP. Biochim Biophys Acta Gen Subj 2018; 1862:2113-2123.

Abstract
Selenoprotein S (SelenoS) is one of the cellular endoplasmic reticulum (ER) and membrane located selenoproteins, and it has the main functions of anti-oxidation, anti-apoptosis and anti-ER stress. To investigate the effect of SelenoS silencing on mouse hepatoma cell death and the intracellular biological function of SelenoS, we knocked down SelenoS in Hepa1-6 cells, and detected ER stress, intracellular calcium homeostasis, mitochondrial dynamics, apoptosis and necrosis. To further explore whether reactive oxygen species (ROS) has an effect on apoptosis and necrosis under SelenoS silencing, we used NAC (2.5 mM) to pretreat cells, and detected ΔΨm, ATP, and apoptosis and necrosis rates. SelenoS silencing broke the intracellular calcium homeostasis, induced mitochondrial dynamic disorder, ROS accumulation, loss of ΔΨm and ATP, and triggered apoptosis and necrosis in mouse hepatoma cells. The clearance of ROS alleviated the loss of ΔΨm and ATP caused by silencing of SelenoS, reduced cell necrosis and increased apoptosis. However, SelenoS silencing did not cause ER stress in Hepa1-6 cells. These results indicate that SelenoS silencing triggers mouse hepatoma cells apoptosis and necrosis through affecting intracellular calcium homeostasis and ROS-mPTP-ATP participates in cell death transformation from apoptosis to necrosis to rise damage.

Abstract
AIM In this study, the relationship of liver tissue trace element concentrations with hepatitis B disease and the effects of several environmental factors were analysed. METHOD The liver tissue concentrations of Al, Fe, Cd, Mn, Cr, Cu, Pb, Ni, Zn, Ag, and Co were evaluated in 92 patients with hepatitis B using the Inductively Coupled Plasma - Mass Spectrometry (ICP/MS) method in the analyses. The patients were divided into the following two groups: low-high Ishak histologic activity index (HAI) (0-6: Low Histologic Activity, 7-18: High Histologic Activity) and low-high fibrosis (FS) (Fibrosis 1,1,2 and Fibrosis 3,4,5,6). The metal levels were compared between the groups. RESULTS The Cd concentration was found to be statistically higher in the group with low HAI scores (p=0.019). The hepatic Cu concentration was found to be higher in women than in men (p=0.046). The hepatic Fe concentration was found to be higher in the group with increased FS compared to the group with decreased FS (p=0.033). Cd was found to be higher in patients who worked in positions involving exposure to heavy metals and in individuals with an ALT level above 40 IU/L (p=0.008). Several correlations have been found between the hepatic tissue metal levels in our study. In a linear regression analysis, Fe and Zn were found to be correlated with the fibrosis scores (p=<0.001 and p=0.029), and Cu was correlated with HAI (p=0.023). In the linear regression model, Ni (p=0.018) and Cr (p=0.011) were correlated with gender. There was a correlation between the hepatic Fe level and the location where hepatitis B patients were living (village/city) (p=0.001), frequency of fish consumption (p=0.045) and smoking (p=0.018) according to the linear regression analysis. Using a logistic regression analysis, Cr (p=0.029), Ni (p=0.031) and Pb (p=0.027) were found to be correlated with smoking habit, and Zn (p=0.010), Ag (p=0.026), Cd (p=0.007) and Al (p=0.005) were correlated with fish consumption. CONCLUSION The liver tissue trace element levels are correlated with disease activity and histologic damage in patients with HepB disease. Additionally, smoking, the environment in which the patient works and the amount of fish consumption affect the accumulation of trace elements in the liver.

Abstract
Hepatitis B virus (HBV) infection is one of the most serious and prevalent health problems worldwide. Current anti‐HBV medications have a number of drawbacks, such as adverse effects and drug resistance; thus, novel potential anti‐HBV reagents are needed. Selenium (Se) has been shown to be involved in both human immunodeficiency virus and hepatitis C virus infections, but its role in HBV infection remains unclear. To address this, sodium selenite (Na2SeO3) was applied to three HBV cell models: HepG2.2.15 cells, and HuH‐7 cells transfected with either 1.1 or 1.3× HBV plasmids. Cytotoxicity of Na2SeO3 was examined by Cell Counting Kit‐8. Levels of viral antigen expression, transcripts, and encapsidated viral DNA were measured by enzyme‐linked immunosorbent assay, northern blot, and Southern blot, respectively. There was no obvious cytotoxicity in either HepG2.2.15 or HuH‐7 cells with <2.5 µM Na2SeO3. Below this concentration, Na2SeO3 suppressed HBsAg and HBeAg production, HBV transcript level, and amount of genomic DNA in all three tested models, and suppression level was enhanced in line with increases in Na2SeO3 concentration or treatment time. Moreover, the inhibitory effect of Na2SeO3 on HBV replication can be further enhanced by combined treatment with lamivudine, entecavir, or adefovir. Thus, the present study clearly proves that Na2SeO3 suppresses HBV protein expression, transcription, and genome replication in hepatoma cell models in a dose‐ and time‐dependent manner. J. Med.

Abstract
The purpose of this study was to assess plasma selenium levels in an Australian blood donor population and measure extra-cellular selenium levels in fresh manufactured blood components. Selenium levels were measured using graphite furnace atomic absorption spectrometry with Zeeman background correction. The mean plasma selenium level in healthy plasmapharesis donors was 85.6±0.5 μg/L and a regional difference was observed between donors in South East Queensland and Far North Queensland. Although participants had selenium levels within the normal range (55.3-110.5 μg/L), 88.5% had levels below 100 μg/L, a level that has been associated with sub-optimal activity of the antioxidant enzyme glutathione peroxidase (GPx). Extra-cellular selenium levels in clinical fresh frozen plasma (cFFP) and apheresis-derived platelets (APH Plt) were within the normal range. Packed red blood cells (PRBC) and pooled buffy coat-derived platelets (BC Plt) had levels at the lower limit of detection, which may have clinical implications to the massively transfused patient.

Abstract
BACKGROUND Nonalcoholic fatty liver disease (NAFLD) may be an important factor leading to altered trace mineral homeostasis, thereby accelerating the progression of hepatitis C virus (HCV) infection. Our aim was to determine whether NAFLD influenced the status of certain essential trace minerals and oxidative stress in chronic HCV-infected patients. DESIGN AND METHODS Blood biochemical parameters were determined in a group of 30 healthy, non-obese, non-diabetic participants (CNL group), and hepatitis C patients without NAFLD (HCV group, n = 30) and with NAFLD (HCV-NAFLD group, n = 32). RESULTS Concentrations of thiobarbituric acid reactive substances (TBARS; a measure of oxidative stress), C-reactive protein (CRP), ferritin, aminotransferases, lipid profiles, and insulin metabolism were markedly abnormal in both patient groups than in CNL subjects. Compared to patients in the HCV group, those with HCV-NAFLD group had lower high-density lipoprotein concentrations, higher low-density lipoprotein and homeostasis model assessment-insulin resistance (HOMA-IR) values, disrupted antioxidant enzyme activities, and elevated TBARS concentrations, as well as decreased plasma concentrations of trace minerals zinc (Zn) and selenium (Se) and increased copper (Cu). The alterations in mineral homeostasis were also linked to TBARS, CRP, ferritin, lipoproteins, and HOMA-IR values in the HCV-NAFLD group. CONCLUSIONS There is a progressive deterioration in the homeostasis of minerals (Zn, Se, and Cu) in HCV-NAFLD patients, which may reflect greater oxidative stress and inflammation. These results suggest that the disturbance in mineral metabolism by NAFLD has an impact on the effectiveness of treatment for chronic HCV infection.
