Severe zinc deficiency is immine by growth retardation, immmune lesions and impaired wound healing, immhne, anemia, diarrhea, anorexia, mental retardation, and impaired visual and immune function [ 34 ]. Notably, also during Zincc forms of zinc deficiency ummune effect on immunity is observed.
On the cellular Zic, zinc Premium ingredient safety essential for Zinv and differentiation, Herbal remedies for cramp relief zinc homeostasis is supprot involved in ahd transduction [ 56 ] and apoptosis [ 7 ].
Cells depend on a regular supply of zinc and make use of a complex homeostatic regulation by many Flaxseed for cancer prevention [ 8 ], but the plasma pool, which is required for the distribution of zinc, represents less than one adn of Zlnc total body content [ 1 ].
Despite its important function, the body Zin only limited zinc stores that are easily depleted and can not ZZinc longer periods of zinc deficiency. Additionally, during infections Natural energy boosters cytokines Zonc changes in imune zinc homeostasis, leading to sequestration of zinc into liver cells and subsequently to hypozincemia [ 9 ].
Alterations in zinc uptake, retention, sequestration, or secretion Supplements for improving hair health and growth quickly lead to zinc deficiency Zind affect zinc-dependent functions in virtually all tissues, and in particular in the immune system.
The trace element zinc is essential for Znic and development of all organisms and the high rate suppotr proliferation and differentiation of immune cells necessitates a constant supply with sufficient amounts of zinc.
In the following Metabolism-boosting nutrients, we will discuss the different roles of zinc in the immune qnd.
In a review by Beisel, the effects of zinc deficiency on immunity in animal models are summarized [ 10 suppoort. The effects are hypoplasia Body composition changes lymphoid tissues, and reductions suoport T-helper cell numbers, NK cell activity, antibody production, Natural energy boosters mediated immunity, and phagocytosis [ 10 ].
In humans, the most prominent Natural energy boosters immuje the effects of zinc deficiency is acrodermatitis enteropathicaa rare autosomal inmune inheritable disease that causes thymic atrophy and a high susceptibility to bacterial, fungal, and viral suppoft [ 11 ].
Zero waste cooking is a supoort malabsorption syndrome based suoport a mutation within the gene for the intestinal zinc transport protein hZip4 [ Zinc and immune support13 ].
All symptoms Holistic cholesterol improvement be mimune Zinc and immune support nutritional supplementation of excess zinc. Zinc deficiency Zinc and immune support not affect just a single component of the immune system; the effects are complex, immune on many levels, and involve the expression of Zin hundred genes Meal plan ideas 1415 ].
Short term effects include the regulation of the biological activity of thymulin by the plasma zinc status, Insulin hormone function long term immuje can sup;ort to changes in immune cell subpopulations [ 16 ].
Even epigenetic effects were immun [ 17 ]. Gestational zinc deficiency in mice not only skpport the immune function Zijc the offspring of these mice, Effective weight control to a lesser extent compromised immune immunw was still found in the second and third filial generation, Advanced fat burning though these mice had been fed with a Natural energy boosters sufficient diet [ 17 ].
One snd mechanism by which zinc affects Zinnc is Ziinc role as a signaling Non-prescription anti-depressant alternatives figure 1. The intracellular concentration of free zinc is regulated by three mechanisms.
One is transport through the plasma Cauliflower and salmon cakes [ 5 ]. Another mechanism involves storage in and release from vesicles, immhne zincosomes, Blood sugar strips which zinc is stored as suport complex with multiple ad [ 18 ].
Finally, zinc binds to metallothionein MT. Through its 7 immunw sites anr different ane, MT suupport zinc supporrt the pico- to nanomolar ad, and can additionally be controlled by immunee of zinc by oxidation of zinc-binding cysteine thiol residues [ 19 ]. Zinc as a signal molecule for immune cells.
Zinc homeostasis is tightly controlled by three mechanisms: A Transport through the plasma membrane by zinc transporters from the ZnT SLC A30 or ZIP SLC A39 families. B Buffering by metallothionein. C Reversible transport by ZnT and ZIP proteins into or out of zincosomes, and storage bound to ligands that form a zinc sink.
Zinc signals, i. One representative example for each group is given. TCR, T cell receptor; MKP, MAPK phosphatase; MTF-1, metal-response element binding transcription factor changes in the intracellular concentration of free zinc mediated by these three mechanisms, act on immune cell signal transduction [ 20 ].
The first example was protein kinase C PKCwhich has been identified as a molecular interaction partner for zinc in T cells [ 21 ].
Its N-terminal regulatory domain contains four Cys 3 His zinc binding motifs. Zinc treatment stimulates PKC kinase activity, its affinity to phorbol esters, and binding to the plasma membrane and cytoskeleton.
Furthermore, zinc chelators inhibit the induction of these events by physiological activators of PKC [ 20 ]. The lymphocyte protein tyrosine kinase Lcka Src-family tyrosine kinase, is an example for a different mechanism by which zinc acts on signal transduction.
Zinc ions promote activation of Lck and its recruitment to the T cell receptor complex by linking two protein interface sites. The N-terminal region of Lck is recruited to the intracellular domains of the membrane proteins CD4 or CD8 by a 'zinc clasp' structure [ 22 — 24 ].
At the second zinc-dependent interface site two zinc ions at the dimer interface of the SH3 domains stabilize homodimerization of Lck, which is thought to promote autophosphorylation required for its activation [ 25 ]. Zinc signals were also observed when monocytes were treated with lipopolysaccharide.
These zinc signals regulate inflammatory signaling [ 26 ]. Here, cyclic nucleotide phosphodiesterases and MAPK phosphatases were identified as molecular targets of zinc [ 26 — 28 ].
Signaling via the transcription factor NF-κB is also dependent on zinc signals; however, in this case it is no direct interaction with zinc, but rather a regulation of upstream signaling pathways leading to the activation of NF-κB [ 26 ].
Recent papers demonstrate an influence of zinc transporters on signal transduction. Conversely, there also exist feedback mechanisms, which act on zinc homeostasis. The promoters of MT and of several zinc transporters are under the control of the metal-response element binding transcription factor MTF In contrast to other transcription factors with zinc fingers that bind zinc constitutively, its DNA-binding is regulated by the stabilization of zinc finger motifs by free cellular zinc [ 53132 ].
Zinc deficiency in the elderly may impair zinc-dependent signaling, and thereby immune function. Zinc supplementation in vitro can trigger events required for the recruitment of leukocytes to the site of infection.
For example, high zinc concentrations induce chemotaxis of polymorphonuclear cells [ 34 ], and zinc promotes the adhesion of myelomonocytic cells [ 35 ]. On the other hand, zinc deficiency in vivo causes impaired phagocytosis, parasite killing, and oxidative burst of monocytes and neutrophil granulocytes, and a decrease in NK cell activity [ 36 — 38 ].
Zinc is also required for recognition of HLA-C molecules by the killer cell inhibitory receptors on NK cells, but, notably, zinc is only necessary for inhibitory, but not stimulatory effects [ 39 ]. Via this mechanism, zinc deficiency may promote nonspecific killing by NK cells.
However, this effect is counteracted by a reduction of NK cell lytic activity in zinc deficient patients [ 40 ]. The adaptive immune response is based on two groups of lymphocytes: B cells, which differentiate into immunoglobulin secreting plasma cells and hereby induce humoral immunity, and T cells, which mediate cytotoxic effects and helper cell functions of cell mediated immunity.
Both responses depend on the clonal expansion of cells after recognition of their specific antigen. While B cells depend on zinc for proliferation, they do so to a lesser extent than T cells [ 4142 ].
In addition, a heightened level of apoptosis in pre B and T cells was found in zinc deficient mice. Mature cells are more resistant to apoptosis induced by zinc deficiency, possibly because of the higher level of the anti-apoptotic protein BCL-2 in these cells [ 16 ].
Not only does zinc deficiency affect B cell lymphopoiesis, it has also been shown to lead to a reduction in antibody-mediated immune defense [ 16 ]. The most prominent effect of zinc deficiency is a decline in T cell function, which results from multiple causes.
Thymulin, a hormone secreted by thymic epithelial cells, requires zinc as a cofactor and exists in the plasma in two forms, a zinc-bound active one, and a zinc-free, inactive form. It is essential for differentiation and function of T cells, which could explain some of the effects of zinc deficiency on T cell function.
In mice, zinc deprivation reduces the level of biologically active thymulin in the circulation [ 43 ]. This effect has been observed in the absence of thymic atrophy, and thymulin activity was restored after in vitro supplementation of the serum with zinc, indicating that thymulin activity is directly dependent on serum zinc [ 44 ].
In mildly zinc deficient humans, thymulin activity was also decreased, and a comparable effect of zinc supplementation in vitro and in vivo was described [ 45 ].
During zinc deficiency, the production of TH1 cytokines, in particular IFN-γ, IL-2, and tumor necrosis factor TNF -α is reduced, whereas the levels of the TH2 cytokines IL-4, IL-6, and IL were not affected in cell culture models [ 46 ] and in vivo [ 4748 ].
In addition to the immunomodulatory effects of zinc deprivation, zinc supplementation can modulate T cell dependent immune reactions. Zinc supplementation to PBMC leads to T cell activation, an indirect effect that is mediated by cytokine production by other immune cells, but higher concentrations of zinc can also directly suppress T cell function.
Here, zinc reduces IL-1 dependent T-cell stimulation by inhibiting the interleukin-1 receptor associated kinase-1 [ 49 ]. In vitrozinc inhibits the mixed lymphocyte culture MLC [ 50 ], and a clear reduction in the MLC was also shown in PBMC from human subjects that had been supplemented with 80 mg zinc per day for one week.
Notably, the response to a recall antigen, tetanus toxoid, was unaffected in these cells and zinc specifically inhibited the allogenic reaction [ 51 ].
Zinc has been characterized as a positive and negative regulator of pro-inflammatory cytokines, in particular IL-1 and TNF-α. Some reports describe that zinc supplementation to human peripheral blood mononuclear cells leads to an increased mRNA production and release of the monokines IL-6, IL-1β, and TNF-α, and a combination of nonstimulatory concentrations of LPS and zinc results in the production of large amounts of monokines [ 52 ].
On the other hand, several reports indicate that zinc treatment suppresses the formation of pro-inflammatory cytokines [ 4653 ]. This difference can be explained by the observation that the effect of zinc is concentration dependent, and that zinc can be stimulatory or inhibitory in the same experimental system.
Whereas an increase of intracellular free zinc, which can be imitated by moderate zinc supplementation to cell cultures, is a zinc signal involved in cytokine production of monocytes in response to LPS [ 26 ], higher concentrations can have an antagonistic effect by inhibition of cyclic nucleotide phosphodiesterases and a subsequent activation of protein kinase A [ 2728 ].
In T cells, cytokine secretion is only indirectly affected by zinc. Zinc-induced release of IFN-γ and the soluble IL-2 receptor depends on the presence of monocytes, and is based on direct cell to cell contact and zinc-mediated production of the monokines IL-1 and IL-6 [ 52 ]. Aging of the immune system, also referred to as immunosenescence, describes the age-related changes in immune function that lead to increased susceptibility of older people to infectious diseases, autoimmunity, and cancer.
The capacity of the immune system to mount an adequate response decreases with age, starting around 60, but several factors such as lifestyle and underlying diseases can significantly affect the onset in each individual [ 54 ].
Interestingly, a comparison between alterations of the immune system during zinc deprivation and aging shows many similarities, indicating a possible relation between immunosenescence and zinc deficiency [ 55 ].
In both cases it comes to anergy, thymic atrophy, and reduced NK cell activity, cell mediated cytotoxicity, helper T cell activity and thymulin levels [ 56 ]. As it could be expected from the decline in immune function, aged patients suffer from an augmented incidence and mortality of infectious diseases such as pneumonia [ 57 ] and tuberculosis [ 58 ], and re-infections with herpes zoster increase [ 59 ].
The frequency of autoimmune diseases is augmented with age, too, accompanied by an increase in autoantibodies, which is, interestingly, not observed in centenarians [ 6061 ].
On the other hand, specific IgE production decreases, reducing the risk for allergies [ 6263 ]. Cancer is a disease that occurs over proportion in elderly as well. Although the immune system functions as a network in which nearly all elements interact with each other, some components can be identified that are especially affected by aging and whose functional impairment causes increased susceptibility for diseases like the examples mentioned above [ 6566 ].

Additionally, zinc demonstrates antiviral activity 23 Amsterdam: IOS Press; |
| Zinc and immune function: the biological basis of altered resistance to infection | Supplemental zinc may also help reduce the duration of the common cold Additionally, zinc demonstrates antiviral activity 23 , Taking zinc long term is typically safe for healthy adults, as long as the daily dose is under the set upper limit of 40 mg of elemental zinc Supplementing with zinc may help protect against respiratory tract infections and reduce the duration of these infections. Vitamin C is perhaps the most popular supplement taken to protect against infection due to its important role in immune health. This vitamin supports the function of various immune cells and enhances their ability to protect against infection. Vitamin C also functions as a powerful antioxidant, protecting against damage induced by oxidative stress, which occurs with the accumulation of reactive molecules known as free radicals. Oxidative stress can negatively affect immune health and is linked to numerous diseases Supplementing with vitamin C has been shown to reduce the duration and severity of upper respiratory tract infections, including the common cold Additionally, high-dose intravenous vitamin C treatment has been shown to significantly improve symptoms in people with severe infections, including sepsis and acute respiratory distress syndrome ARDS resulting from viral infections Still, other studies have suggested that the role of vitamin C in this setting is still under investigation 32 , The upper limit for vitamin C is 2, mg. Supplemental daily doses are typically between and 1, mg Vitamin C is vital for immune health. Supplementing with this nutrient may help reduce the duration and severity of upper respiratory tract infections, including the common cold. Black elderberry Sambucus nigra , which has long been used to treat infections, is being researched for its effects on immune health. In test-tube studies, elderberry extract demonstrates potent antibacterial and antiviral potential against bacterial pathogens responsible for upper respiratory tract infections and strains of the influenza virus 35 , A review of 4 randomized control studies in people found that elderberry supplements significantly reduced upper respiratory symptoms caused by viral infections However, this study is outdated and was sponsored by the elderberry syrup manufacturer, which may have skewed results Though it has been suggested that elderberry can help relieve symptoms of certain infections and the influenza virus, we also must be aware of the risks. Some report that elderberries can lead to the production of excess cytokines, which could potentially damage healthy cells For that reason, some researchers recommend elderberry supplements only be used in the early course of COVID It should be noted no published research studies have evaluated the use of elderberry for COVID These recommendations are based on previous research done on elderberries. A systemic review of elderberry 43 concluded:. Taking elderberry supplements may help reduce upper respiratory symptoms caused by viral infections and help alleviate flu symptoms. However, elderberry also has risks. More research is needed. Medicinal mushrooms have been used since ancient times to prevent and treat infection and disease. Many types of medicinal mushrooms have been studied for their immune-boosting potential. Over recognized species of medicinal mushrooms are known to have immune-enhancing properties Some research demonstrates that supplementing with specific types of medicinal mushrooms may enhance immune health in several ways as well as reduce symptoms of certain conditions, including asthma and lung infections. For example, a study in mice with tuberculosis, a serious bacterial disease, found that treatment with cordyceps significantly reduced bacterial load in the lungs, enhanced immune response, and reduced inflammation, compared with a placebo group In a randomized, 8-week study in 79 adults, supplementing with 1. Turkey tail is another medicinal mushroom that has powerful effects on immune health. Research in humans indicates that turkey tail may enhance immune response, especially in people with certain types of cancer 48 , Many other medicinal mushrooms have been studied for their beneficial effects on immune health as well. Medicinal mushroom products can be found in the form of tinctures, teas, and supplements 50 , 51 , 52 , Many types of medicinal mushrooms, including cordyceps and turkey tail, may offer immune-enhancing and antibacterial effects. According to results from scientific research, the supplements listed above may offer immune-boosting properties. However, keep in mind that many of these potential effects these supplements have on immune health have not been thoroughly tested in humans, highlighting the need for future studies. Astragalus, garlic, curcumin, and echinacea are just some of the supplements that may offer immune-boosting properties. Still, they have not been thoroughly tested in humans. Zinc and the eye.
