The Protective Effect of the Crosstalk between Zinc Hair Concentration and Lymphocyte Count-Preliminary Report. Life (Basel) 2024; 14:571. [PMID: 38792593 PMCID: PMC11122497 DOI: 10.3390/life14050571] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2024] [Revised: 04/20/2024] [Accepted: 04/28/2024] [Indexed: 05/26/2024] Open
Abstract
BACKGROUND An imbalance between pro- and anti-inflammatory mechanisms is indicated in the pathophysiology of atherosclerotic plaque. The coronary artery and carotid disease, despite sharing similar risk factors, are developed separately. The aim of this study was to analyze possible mechanisms between trace element hair-scalp concentrations and whole blood counts that favor atherosclerotic plaque progression in certain locations. METHODS There were 65 (36 (55%) males and 29 (45%) females) patients with a median age of 68 (61-73) years enrolled in a prospective, preliminary, multicenter analysis. The study group was composed of 13 patients with stable coronary artery disease (CAD group) referred for surgical revascularization due to multivessel coronary disease, 34 patients with carotid artery disease (carotid group) admitted for vascular procedure, and 18 patients in a control group (control group). RESULTS There was a significant difference between the CAD and carotid groups regarding lymphocyte (p = 0.004) counts. The biochemical comparison between the coronary and carotid groups revealed significant differences regarding chromium (Cr) (p = 0.002), copper (Cu) (p < 0.001), and zinc (Zn) (p < 0.001) concentrations. Spearman Rank Order Correlations between lymphocyte counts and trace elements in the analyzed groups were performed, revealing a strong correlation with zinc (R = 0.733, p < 0.001) in the control group (non-CAD, non-carotid). CONCLUSION Significant differences in hair-scalp concentrations related to atherosclerosis location were observed in our analysis. The interplay between zinc concentration and lymphocyte count may play a pivotal role in cardiovascular disease development.

[PMID: 36924587 DOI: 10.1016/j.jtemb.2023.127152] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/09/2023] [Revised: 02/20/2023] [Accepted: 03/02/2023] [Indexed: 03/13/2023]
Abstract
BACKGROUND Zinc, one of the most important essential trace elements in the human body, regulates a wide range of cellular functions of immune cells, such as proliferation, differentiation and survival. Zinc deficiency affects both the innate and adaptive immune system. Zinc supplementation was discussed as possible therapy for infectious diseases and T cell-mediated autoimmune diseases. However, the influence of commercial zinc preparations on proliferation and cytokine production of resting and antigen-stimulated peripheral blood mononuclear cells (PBMC) has not yet been completely investigated. METHODS Here, we examined whether zinc aspartate (Unizink®), an approved drug to treat zinc deficiency in patients, induces proliferation, cytokine production, and induction of apoptosis/caspase 3/7 activity of resting PBMC under high-density cell culture condition. In addition, we performed antigen-specific proliferation experiments, where PBMCs of healthy donors vaccinated against Influenza A (H1N1) and/or SARS-CoV-2 were stimulated with Influenza A (H1N1) peptides or SARS-CoV-2 peptides as well as the Mixed Lymphocyte Culture (MLC) in the presence of increasing concentrations of zinc aspartate. RESULTS We observed a dose-dependent enhancement of proliferation and induction of cytokine production (IFN-γ, IL-5, GM-CSF and CXCL10) of resting PBMC in presence of zinc aspartate. The number of cells with active caspase 3/7 and, consecutively, the amount of cells undergoing apoptosis steadily decreased in presence of zinc aspartate. Moreover, zinc aspartate was capable of stimulating antigen-specific PBMC proliferation using MLC or influenza A (H1N1) and SARS-CoV-2 peptides in both a dose-dependent and a donor-specific manner. In the absence of zinc aspartate, we clearly could discriminate two groups of responders: low and high responders to antigenic stimulation. The addition of increasing concentration of zinc aspartate significantly stimulated the proliferation of PBMC from low responders, but not from high responders. CONCLUSION Taken together, our results suggest that zinc aspartate induces the proliferation of resting and antigen-stimulated PBMCs under high-density cell culture conditions. Thus, zinc might represent a supportive treatment in patients suffering from infectious diseases.

Abstract
Obesity is associated with the development of various complications, including diabetes, atherosclerosis, and an increased risk for infections, driven by dysfunctional innate immune responses. Recent insights have revealed that the availability of nutrients is a key determinant of innate immune cell function. Although the presence of obesity is associated with overnutrition of macronutrients, several micronutrient deficiencies, including Vitamin D and zinc, are often present. Micronutrients have been attributed important immunomodulatory roles. In this review, we summarize current knowledge of the immunomodulatory effects of Vitamin D and zinc. We also suggest future lines of research to further improve our understanding of these micronutrients; this may serve as a stepping-stone to explore micronutrient supplementation to improve innate immune cell function during obesity.

Abstract
In response to the enormous threat to human survival and development caused by the large number of viruses, it is necessary to strengthen the defense against and elimination of viruses. Metallic materials have been used against viruses for thousands of years due to their broad-spectrum antiviral properties, wide sources and excellent physicochemical properties; in particular, metal nanoparticles have advanced biomedical research. However, researchers in different fields hold dissimilar views on the antiviral mechanisms, which has slowed down the antiviral application of metal nanoparticles. As such, this review begins with an exhaustive compilation of previously published work on the antiviral capacity of metal nanoparticles and other materials. Afterwards, the discussion is centered on the antiviral mechanisms of metal nanoparticles at the biological and physicochemical levels. Emphasis is placed on the fact that the strong reducibility of metal nanoparticles may be the main reason for their efficient inactivation of viruses. We hope that this review will benefit the promotion of metal nanoparticles in the antiviral field and expedite the construction of a barrier between humans and viruses.

J Trace Elem Med Biol 2022; 71:126956. [PMID: 35217499 PMCID: PMC8853960 DOI: 10.1016/j.jtemb.2022.126956] [Citation(s) in RCA: 42] [Impact Index Per Article: 21.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/26/2021] [Revised: 01/18/2022] [Accepted: 02/15/2022] [Indexed: 02/06/2023]
Abstract
BACKGROUND AND AIM The COVID-19 pandemic has severely affected the world's population in the last two years. Along with non-pharmacological public health interventions, major efforts have also been made to identify effective drugs or active substances for COVID-19 prevention and treatment. These include, among many others, the trace elements zinc and selenium, based on laboratory studies and some observational human studies. However, both of these study designs are not adequate to identify and approve treatments in human medicine, and experimental studies in the form of randomized controlled trials are needed to demonstrate the effectiveness and the safety of any interventions. METHODS We undertook a systematic review in which we searched for published and unpublished clinical trials using zinc or selenium supplementation to treat or prevent COVID-19 in the Pubmed, Scopus and ClinicalTrials databases up to 10 January 2022. RESULTS Amongst the published studies, we did not find any trial with selenium, whereas we retrieved four eligible randomized clinical trials using zinc supplementation, only one of which was double-blind. One of these trials looked at the effect of the intervention on the rate of new SARS-CoV-2 infections, and three at the COVID-19 clinical outcome in already infected individuals. The study populations of the four trials were very heterogeneous, ranging from uninfected individuals to those hospitalized for COVID-19. Only two studies investigated zinc alone in the intervention arm with no differences in the endpoints. The other two studies examined zinc in association with one or more drugs and supplements in the intervention arm, therefore making it impossible to disentangle any specific effects of the element. In addition, we identified 22 unpublished ongoing clinical trials, 19 on zinc, one on selenium and two on both elements. CONCLUSION No trials investigated the effect of selenium supplementation on COVID-19, while the very few studies on the effects of zinc supplementation did not confirm efficacy. Therefore, preventive or therapeutic interventions against COVID-19 based on zinc or selenium supplementation are currently unjustified, although when the results of the on-going studies are published, this may change our conclusion.

Synoviocytes from pigmented villonodular synovitis are less sensitive to cadmium-induced cell death than synoviocytes from rheumatoid arthritis. Sci Rep 2022; 12:3832.

Abstract
Pigmented villonodular synovitis (PVNS) is a rare inflammatory articular disease sharing common characteristics with rheumatoid arthritis (RA), notably hyperplasia of the synovium due to a hyperproliferation of synoviocytes, and with cancer owing to mutations of the CSF1/M-CCSF gene. Targeting synovium hyperplasia by the local delivery of Cadmium (Cd) has been already tested in vitro and in vivo models of RA and could be applied to PVNS. PVNS and RA synoviocytes were exposed to low doses of Cd. After different culture time points, a qualitative analysis was done by microscopy and quantitative measurements of apoptosis, cell viability and IL-6 production were carried. IL-6 production by PVNS synovial tissue was also quantified after Cd treatment with or without the presence of pro-inflammatory cytokines (IL-17 + TNF). Addition of Cd induced cell death in both PVNS (1 ppm) and RA (0.1 ppm) synoviocytes, which increased with time and Cd concentrations. Cd increased the percentage of apoptotic cells and decreased cell viability and IL-6 production. In all these experiments, PVNS synoviocytes were tenfold less sensitive to Cd than RA synoviocytes. Cd decreased IL-6 production by PVNS synovial tissue and its effect was enhanced with pro-inflammatory cytokines. In summary, PVNS synoviocytes show resistance to Cd-induced cell death and decreased inflammation. Intra-articular use of Cd could represent a potential therapeutic tool in PVNS.

Abstract
SCOPE T cell activation requires a metabolic reprogramming from oxidative phosphorylation to aerobic glycolysis to rapidly provide substrates for biosynthesis. An individual's zinc status plays an important role in balancing the activation of T cells and is required for a proper function of immune cells. Furthermore, zinc plays an important role during effector T cell polarization to T helper cell subsets or regulatory T cells, with effector T cells relying on glycolysis and regulatory T cells on oxidative phosphorylation. Therefore, we aimed to analyze if zinc also impacts on T cell activation on the level of intracellular metabolism. METHODS AND RESULTS We used mixed lymphocyte culture and anti-CD3/CD28 stimulation as in vitro models for T cell activation to investigate the effect of zinc supplementation and deprivation on metabolic switching. We observed promoted glucose uptake, insulin receptor expression and signaling in both zinc conditions, whereas key metabolic enzymes were stimulated mainly by zinc deprivation. Alterations in cytokine production suggest an immune-activating effect of zinc deprivation and a balancing effect of zinc supplementation. CONCLUSION Our results suggest a supportive effect of both zinc supplementation and deprivation on the metabolic switch during T cell activation, adding another level of immune regulation by zinc.

Abstract
Thoracoabdominal aortic aneurysm (TAAA) repair is related to a relevant morbidity and in-hospital mortality rate. In this retrospective observational single-center study including serum zinc levels of 33 patients we investigated the relationship between zinc and patients’ outcome following TAAA repair. Six patients died during the hospital stay (18%). These patients showed significantly decreased zinc levels before the intervention (zinc levels before intervention: 60.09 µg/dl [survivors] vs. 45.92 µg/dl [non-survivors]). The post-interventional intensive care SOFA-score (Sepsis-related organ failure assessment) (at day 2) as well as the SAPS (Simplified Acute Physiology Score) (at day 2) showed higher score points in case of low pre-interventional zinc levels. No significant correlation between patient comorbidities and zinc level before intervention, except for peripheral arterial disease (PAD), which was significantly correlated to reduced baseline zinc levels, was observed. Septic shock, pneumonia and urinary tract infections were not associated to reduced zinc levels preoperatively as well as during therapy. Patients with adverse outcome after TAAA repair showed reduced pre-interventional zinc levels. We speculate that decreased zinc levels before intervention may be related to a poorer outcome because of poorer physical status as well as negatively altered perioperative inflammatory response.
