Abstract
Inflammation is a physiological event that protects tissues from infection and injury. Chronic inflammation causes immune cell over activation and sustained release of inflammatory cytokines and chemokines cause pathologic conditions including autoimmune diseases. Heavy metals exposure affects innate and adaptive immune systems through triggering inflammatory responses. It seems that extended inflammatory responses could accelerate heavy metal-induced autoimmunity. In the present review we discuss the exposure route and toxicity of Cadmium (Cd), Lead (Pb), Mercury (Hg), Vanadium (V) and Platinum (Pt) and their effects on inflammatory responses by innate and adaptive immune system and autoimmunity.

Abstract
BACKGROUND The immunotoxicity induced by vanadium exposure have been reported in some toxicology researches. However, evidence from population-based epidemiological studies was lacking. METHODS This study was conducted to assess the associations between prenatal and postnatal exposure to vanadium and immune function of children. A total of 407 pre-school aged children were followed, whose peripheral blood was collected for T lymphocyte subsets and inflammatory cytokines analysis, as well as vanadium concentration measurement. Maternal urine samples were also collected to measure vanadium concentration. We used generalized linear models to evaluate the associations of maternal and children vanadium concentration with children's immune function. Stratification analysis was further conducted to explore the potential gender-specific effects. RESULTS The geometric means of vanadium concentration in maternal urine and children plasma were 0.85 and 1.12 μg/L, respectively. Maternal urinary vanadium was inversely associated with the percentage of CD3+CD4+ cells [-5.53 % (-10.38 %, -0.41 %)] and absolute counts of CD3+ cells [-2.43 % (-5.05 %, 0.25 %)], and we only observed significant negative associations in males when stratifying by fetal gender. Children plasma vanadium was also associated with reduced absolute counts of CD3+ cells [-5.25 % (-9.57 %, -0.73 %)], but gender-specific effects were not observed. No significant associations of vanadium exposure with cytokines were found. CONCLUSIONS Prenatal and postnatal exposure to vanadium had suppressive impacts on childhood cellular immune. Further studies are needed to confirm our findings.

Abstract
The aim of the study was to assess the effect of inorganic vanadium (V) supplementation on antioxidant enzymes, immune status, and haemato-biochemical attributes of growing crossbred calves. Twenty-four male Karan Fries calves (Tharparkar × Holstein Friesian) (initial body mass 72.83 ± 2.5 kg; age 3-9 month) were randomly allocated to four groups: the control (received basal diet devoid of supplemental V), the 3 ppm (received basal diet with 3 mg/kg V), the 6 ppm (received basal diet with 6 mg/kg V) and the 9 ppm group (received basal diet with 9 mg/kg V). All the calves were fed for 150 days as per ICAR (2013) feeding standards to meet their nutrient requirements for 500 g growth rate/day. Peripheral blood samples were collected at the start of experiment and subsequently at 30, 60, 90, 120 and 150 days post-V supplementation for determination of antioxidant enzyme activity, immunological parameters and haemato-biochemical attributes. Results indicated that dietary supplementation of V did not affect daily gain, feed intake and haematological parameters. Crossbred calves fed with 9 mg V/kg diet showed reduced (P < 0.05) plasma total cholesterol concentration; however, plasma total protein and glucose concentration remained unaltered. Glutathione peroxidase (GPx) activity as well as immunoglobulin G (IgG) concentration was significantly (P < 0.05) higher in group supplemented with 9 mg V/kg DM; however, superoxide dismutase (SOD), catalase activity and total plasma immunoglobulin (Ig) concentration were similar in all experimental group. Dietary V supplementation showed a negative relation with plasma thiobarbituric acid reactive substances (TBARS) concentration, whereas non-esterified fatty acid (NEFA) concentration remained unaltered among all groups. Plasma V level increased (P < 0.05) with increasing dietary V levels without affecting levels of Ca, Mg, Fe, Cu and Zn. In conclusion, a dietary addition of 9 mg V/kg DM reduced cholesterol content and improved antioxidant and immune response in growing crossbred calves.

Abstract
Over the last decade, a diverse spectrum of vanadium compounds has arisen as anti-inflammatory therapeutic metallodrugs targeting various diseases. Recent studies have demonstrated that select well-defined vanadium species are involved in many immune-driven molecular mechanisms that regulate and influence immune responses. In addition, advances in cell immunotherapy have relied on the use of metallodrugs to create a "safe," highly regulated, environment for optimal control of immune response. Emerging findings include optimal regulation of B/T cell signaling and expression of immune suppressive or anti-inflammatory cytokines, critical for immune cell effector functions. Furthermore, in-depth perusals have explored NF-κB and Toll-like receptor signaling mechanisms in order to enhance adaptive immune responses and promote recruitment or conversion of inflammatory cells to immunodeficient tissues. Consequently, well-defined vanadium metallodrugs, poised to access and resensitize the immune microenvironment, interact with various biomolecular targets, such as B cells, T cells, interleukin markers, and transcription factors, thereby influencing and affecting immune signaling. A synthetically formulated and structure-based (bio)chemical reactivity account of vanadoforms emerges as a plausible strategy for designing drugs characterized by selectivity and specificity, with respect to the cellular molecular targets intimately linked to immune responses, thereby giving rise to a challenging field linked to the development of immune system vanadodrugs.

ENVIRONMENTAL TOXICOLOGY 2015; 30:1309-1321. [PMID: 24801245 DOI: 10.1002/tox.22001] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/01/2014] [Revised: 04/18/2014] [Accepted: 04/25/2014] [Indexed: 06/03/2023]
Abstract
The purpose of this study was to examine the toxicological effects of nickel chloride (NiCl2 ; 300, 600, and 900 mg kg(-1) diet) on the cytokine mRNA expression and protein levels in the intestinal mucosa and cecal tonsil, and on the ileac and cecal tonsil T cells in broilers by the methods of qRT-PCR, flow cytometry and ELISA for 42 days. Results showed that the IL-2, IL-6, IL-10, IL-17, IFN-γ, and TNF-α (LITAF) cytokine mRNA expression and protein levels were lower (P < 0.05 or P < 0.01) and the percentages of T-cell subsets were also lower in the 300, 600, and 900 mg kg(-1) groups than in the control group. It was concluded that dietary NiCl2 in excess of 300 mg kg(-1) could reduce cytokine mRNA expression and protein levels in the intestinal mucosa and cecal tonsil, and the percentages of ileac and cecal tonsil T-cell subsets. Decreasing in cytokine mRNA expression and protein levels of intestinal mucosa and cecal tonsil induced by NiCl2 was closely related to the reduction of T-cell population. Thus, the abnormal expression of these cytokines impacts the intestinal mucosal immune function by the pathways of reducing of lymphocyte population and activation. Also, this study first proved that NiCl2 at higher levels has the toxicological effects on intestinal mucosal immunity.

Abstract
The purpose of this study was to define the toxic effects of vanadium on thymic development in broilers fed on diets supplemented with 0, 5, 15, 30, 45 and 60 mg/kg of vanadium for 42 days. We examined the changes of relative weigh, cell cycle phase, apoptotic cells, and protein expression of Bcl-2, Bax, and caspase-3 in the thymus by the methods of flow cytometry, TUNEL (terminal-deoxynucleotidyl transferase mediated nick end labeling) and immunohistochemistry. The results showed that dietary high vanadium (30 mg/kg, 45 mg/kg and 60 mg/kg) caused the toxic effects on thymic development, which was characterized by decreasing relative weigh, increasing G0/G1 phase (a prolonged nondividing state), reducing S phase (DNA replication) and proliferating index (PI), and increasing percentages of apoptotic thymocytes. Concurrently, the protein expression levels of Bax and caspase-3 were increased, and protein expression levels of Bcl-2 were decreased. The thymic development suppression caused by dietary high vanadium further leads to inhibitive effects on T lymphocyte maturity and activity, and cellular immune function. The above-mentioned results provide new evidences for further understanding the vanadium immunotoxicity. In contrast, dietary 5 mg/kg vanadium promoted the thymic development by increasing relative weigh, decreasing G0/G1 phase, increasing S phase and PI, and reducing percentages of apoptotic thymocytes when compared to the control group and high vanadium groups.

The purpose of this study was to define the inhibitive effects of dietary nickel chloride (NiCl2) on thymocytes in broilers fed on diets supplemented with 0, 300, 600, and 900 mg/kg of NiCl2 for 42 days. We examined the changes of cell cycle phase, percentages of apoptotic cells, T cell subsets, cytokines, and mRNA expression of apoptotic proteins (bcl-2, bax, and caspase-3) in thymocytes by flow cytometry and quantitative real-time polymerase chain reaction (qRT-PCR). In the NiCl2-treated broilers, the percentages of thymocytes in G0/G1 phase were increased, whereas thymocytes in the S phase and the proliferation index were decreased. The percentages of apoptotic thymocytes were increased. Also, the mRNA expression levels of bax and caspase-3 were increased, and mRNA expression levels of bcl-2 were decreased. The percentages of CD3(+), CD3(+)CD4(+), and CD3(+)CD8(+) T lymphocytes in the thymus and peripheral blood were diminished. Concurrently, thymic cytokine (interleukin-1 beta (IL-1β), interleukin-2 (IL-2), interleukin-10 (IL-10), interleukin-12 p35 subunit (IL-12p35), interleukin-12 p40 subunit (IL-12p40), interleukin-21 (IL-21), interferon gamma (IFN-γ), tumor necrosis factor alpha (TNF-α), thymosin β4, thymosin β10, and thymosin β15) mRNA expression levels were decreased. The abovementioned results showed that dietary NiCl2 in excess of 300 mg/kg inhibited thymocyte growth by arresting cell cycle, increasing apoptosis percentage, altering apoptotic protein mRNA expression levels, and downregulating cytokine expression levels.

Abstract
This study was designed to evaluate the effects of dietary nickel chloride (NiCl2) on the splenic immunity in broilers by observing changes of cytokine mRNA expression and protein levels, immunoglobulin (IgA, IgG, and IgM) contents, and IgA+ B cell and T-cell numbers using the methods of qRT-PCR, flow cytometry (FCM), and ELISA. A total of 240 1-day-old avian broilers were equally allocated into four groups and fed on a corn-soybean basal diet as the control diet or the same diet supplemented with 300, 600, and 900 mg/kg NiCl2 for 42 days. The mRNA expression and protein levels of IL-2, IL-6, IL-10, IL-12, TNF-α/LITAF, IFN-γ, and IgA, IgG, and IgM contents were significantly decreased (p<0.05 or p<0.01) in the 300-, 600-, and 900-mg/kg NiCl2 groups when compared with those of the control group, which was consistent with the reduction of T-cell subset percentages and IgA+ B cell numbers in the 300-, 600-, and 900-mg/kg NiCl2 groups. The abovementioned results showed that dietary NiCl2 in excess of 300 mg/kg caused damage on splenocytes and splenic immune function. The results of the present study provided new experimental evidences for further study on the effect mechanism of NiCl2 on splenic immunity.

Abstract
The purpose of this 42-day study was to examine the effect of dietary vanadium on intestinal microorganism diversity in the duodenum, ileum, cecum, and rectum segments of broilers by the plate count and polymerase chain reaction-denaturing gradient gel electrophoresis (DGGE). A total of 420 1-day-old avian broilers were divided into six groups and fed on a control diet or the same diet supplemented with vanadium at the doses of 5, 15, 30, 45, and 60 mg/kg in the form of ammonium metavanadate. In comparison with control group, the dietary vanadium at the doses of 45 and 60 mg/kg could decrease the counts of Bifidobacterium spp. in the intestinal tract at 21 and 42 days of age. With increasing level in dietary vanadium, the counts of Escherichia coli were significantly increased in the ileum, cecum, and rectum and were decreased in the duodenum at 21 and 42 days of age. However, the counts of Lactobacilli were decreased in the cecum and rectum and increased in the ileum of 45 and 60 mg/kg groups. The colonization of these three bacteria could be affected by dietary vanadium. DGGE analysis showed that the number of bands in duodenum, ileum, cecum, and rectum were obviously decreased in the 30, 45, and 60 mg/kg groups at 21 and 42 days of age. In conclusion, the dietary vanadium in excess of 30 mg/kg could alter the amount and diversity of intestinal bacteria in broilers, implying that the structure and initial balance in the intestinal microbiota were disrupted.

Abstract
The cecal tonsil of broiler is known as a secondary lymphoid tissue, which is involved in antigen-specific humoral immune responses. The purpose of this study was to investigate the effects of dietary vanadium on the tissue distribution and quantity of immunoglobulin A-positive (IgA(+)) cell in the cecal tonsil by immunohistochemistry. Simultaneously, the changes in interleukin-6 (IL-6), interleukin-10 (IL-10), interferon gamma (IFN-γ) and tumor necrosis factor-alpha (TNF-α) contents in the cecal tonsil were also quantified by enzyme-linked immunosorbent assay (ELISA). A total of 420 one-day-old avian broilers were divided into six groups and fed on a corn-soybean basal diet (control diet) or the same diet supplemented respectively with 5, 15, 30, 45, and 60 mg/kg of vanadium in the form of ammonium metavanadate for 42 days. The results showed that the population of the IgA(+) cells in the cecal tonsil were significantly lower (p < 0.05 or p < 0.01) in the 45 and 60 mg/kg groups than that in the control group. Meanwhile, IL-10, IFN-γ and TNF-α contents in the cecal tonsil were significantly decreased (p < 0.05 or p < 0.01) in the 30, 45 and 60 mg/kg groups in comparison with those of the control group. However, IL-6 content in the cecal tonsil was only decreased (p < 0.05 or p < 0.01) in 60 mg/kg at 14 and 28 days of age. In conclusion, dietary vanadium in excess of 30 mg/kg reduced the numbers of the IgA(+) cells and changed the contents of the abovementioned cytokines in the cecal tonsil, which may finally impact the function of local mucosal humoral immunity in broilers.

Abstract
The purpose of this 42-day study was to examine the effect of dietary vanadium on the ileac T cells and contents of cytokines including interleukin-2 (IL-2), interleukin-6 (IL-6), and interferon-gamma (IFN-γ) in broilers by flow cytometry and enzyme-linked immunosorbent assay. A total of 420 one-day-old avian broilers were divided into six groups (seven replicates in each group and ten broilers in each replicate) and fed on control diet or the same diet supplemented with 5, 15, 30, 45, and 60 mg/kg vanadium in the form of ammonium metavanadate. The results showed that the percentages of CD3(+), CD3(+)CD4(+), and CD3(+)CD8(+) T cells in both ileac lamina propria lymphocytes (LPLs) and intraepithelial lymphocytes (IELs) were significantly lower (P < 0.05 or P < 0.01) in the 45- and 60-mg/kg groups than in the control group from 14 to 42 days of age. The CD4(+)/CD8(+) ratio was increased in ileac LPLs in the 60-mg/kg group at 28 days of age, and in ileac IELs in the 60-mg/kg group at 28 days of age and in the 45-mg/kg group at 42 days of age. Meanwhile, the ileac IL-2, IL-6 contents were decreased (P < 0.05 or P < 0.01) in the 60-mg/kg group from 14 to 42 days of age and in the 45-mg/kg group from 28 to 42 days of age in comparison with those of the control group. It was concluded that dietary vanadium in excess of 30 mg/kg reduced the ileac T cell population and percentages of T cell subsets, and IL-2, IL-6, and IFN-γ contents, implying that the immune function of local intestinal mucosa in broilers could be affected by the dietary vanadium.

Abstract
The purpose of this 42-day study was to investigate the apoptosis in the bursa of Fabricius induced by different levels of dietary vanadium. A total of 420 1-day-old avian broilers were divided into 6 groups in which there were 7 replicates in each group and 10 broilers in each replicate and fed on a corn-soybean basal diet as control diet (vanadium 0.073 mg/kg) or the same diet amended to contain 5, 15, 30, 45, and 60 mg/kg vanadium supplied as ammonium metavanadate (NH(4)VO(3)). Ultrastructurally, mitochondrial injury and increased numbers of apoptotic cells with condensed nuclei were observed in the 30, 45, and 60 mg/kg groups. As measured by flow cytometry, the percentages of apoptotic lymphocytes were significantly increased in the 15-, 30-, 45-, and 60-mg/kg groups when compared with those of control group. Meanwhile, the terminal deoxynucleotidyl transferase 2'-deoxyuridine 5'-triphosphate nick end-labeling assay showed that there were increased numbers of apoptotic cells in the 30-, 45-, and 60-mg/kg groups. Immunohistochemical tests showed increased numbers of positive cells under Bax and caspase-3 protein detection and decreased Bcl-2 protein in the 15-, 30-, 45-, and 60-mg/kg groups. The vanadium content of the bursa was found to be significantly increased in the 30-, 45-, and 60-mg/kg groups. These results suggested that dietary vanadium in excess of 15 mg/kg could cause lymphocyte apoptosis in the bursa of Fabricius and impact humoral immunity in broilers. Lymphocyte apoptosis in the bursa induced by high levels of dietary vanadium is associated with mitochondrial injury and changes in levels of apoptogenic proteins, such as Bcl-2, Bax, and caspase-3.

Abstract
The purpose of this study was to investigate the renal and hepatic oxidative damage and toxicity caused by dietary high vanadium in broilers. A total of 420 one-day-old avian broilers were divided into six groups and fed on a corn-soybean basal diet as control diet (vanadium 0.073 mg/kg), and five high vanadium diets (vanadium 5 mg/kg, high vanadium group I; 15 mg/kg, high vanadium group II; 30 mg/kg, high vanadium group III; 45 mg/kg, high vanadium group IV; and 60 mg/kg, high vanadium group V) throughout the experimental period of 42 days. The results showed that the renal and hepatic superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities, ability to inhibit hydroxy radical, and malondialdehyde (MDA), glutathione, and vanadium contents were not significantly changed in high vanadium group I and II when compared with those of the control groups. However, the SOD and GSH-Px activities, ability to inhibit hydroxy radical, and GSH content were significantly decreased, and the MDA and vanadium contents were markedly increased in high vanadium groups III, IV, and V. At the same time, the lesions were also observed in the kidney and liver of high vanadium groups III, IV, and V. The renal tubular epithelial cells showed granular degeneration and vacuolar degeneration, and hepatocytes showed granular degeneration, vacuolar degeneration, and fatty degeneration. It was concluded that dietary vanadium in the range of 30-60 mg/kg could cause oxidative damage and vanadium accumulation, which induced renal and hepatic toxicity and lesions. The renal and hepatic function was finally impaired in boilers.
