Haghmorad D, Soltanmohammadi A, Jadid Tavaf M, Zargarani S, Yazdanpanah E, Shadab A, Yousefi B. The protective role of interaction between vitamin D, sex hormones and calcium in multiple sclerosis. Int J Neurosci 2024; 134:735-753. [PMID: 36369838 DOI: 10.1080/00207454.2022.2147431] [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: 07/03/2022] [Revised: 11/01/2022] [Accepted: 11/07/2022] [Indexed: 11/14/2022]
Abstract
Multiple sclerosis (MS) is a neurological disorder that causes disability and paralysis, especially among young adults. Although interactions of several factors, such as viral infections, autoimmunity, genetic and environmental factors, performance a role in the beginning and progression of the disease, the exact cause of MS is unknown to date. Different immune cells such as Th1 and Th17 play an impressive role in the immunopathogenesis of MS, while, regulatory cells such as Th2 and Treg diminish the severity of the illness. Sex hormones have a vital role in many autoimmune disorders, including multiple sclerosis. Testosterone, estrogen and progesterone have various roles in the progress of MS, which higher prevalence of disease in women and more severe in men reveals the importance of sex hormones' role in this disease. Vitamin D after chemical changes in the body, as an active hormone called calcitriol, plays an important role in regulating immune responses and improves MS by modulating the immune system. The optimum level of calcium in the body with vitamin D modulates immune responses and calcium as an essential ion in the body plays a key role in the treatment of autoimmune diseases. The interaction between vitamin D and sex hormones has protective and therapeutic effects against MS and functional synergy between estrogen and calcitriol occurs in disease recovery. Moreover, vitamin D and calcium interact with each other to regulate the immune system and shift them to anti-inflammatory responses.

Abstract
Autoreactive T cells, particularly those characterized by a Th17 phenotype, exert significant influence on the pathogenesis of multiple sclerosis (MS). The present study aimed to elucidate the impact of individual and combined administration of vitamin A and D on neuroinflammation, and microRNAs (miRNAs) involved in T helper (Th)17 development, utilizing a murine model of experimental autoimmune encephalomyelitis (EAE). EAE was induced in C57BL/6 mice, and 3 days prior to immunization, intraperitoneal injections of vitamins A and D or their combination were administered. Th17 cell percentages were determined in splenocytes utilizing intracellular staining and flow cytometry. Furthermore, the expression of Ror γ-t, miR-98-5p and Let-7a-5p, was measured in both splenocytes and spinal cord tissues using RT-PCR. Treatment with vitamin A and D resulted in a reduction in both disease severity in EAE mice. Treated mice showed a decreased frequency of Th17 cells and lower expression levels of IL17 and Ror γ-t in splenocytes and spinal cord. The spinal cord tissues and splenocytes of mice treated with vitamins A, D, and combined A+D showed a significant upregulation of miR-98-5p and Let-7a-5p compared to the EAE group. Statistical analysis indicated a strong negative correlation between miR-98-5p and Let-7a-5p levels in splenocytes and Ror-t expression. Our findings indicate that the administration of vitamins A and D exerts a suppressive effect on neuroinflammation in EAE that is associated with a reduction in the differentiation of T cells into the Th17 phenotype and is mediated by the upregulation of miR-98-5p and Let-7a-5p, which target the Ror γ-t.

Abstract
BACKGROUND Mesenchymal stem cells (MSCs) modulate immune responses, and their immunomodulatory potential can be enhanced using inflammatory cytokines. Here, the modulatory effects of IFN-γ-licensed MSCs on expression of T cell-related chemokines and chemokine receptors were evaluated using an experimental autoimmune encephalomyelitis (EAE) model. MATERIAL AND METHODS EAE was induced in 3 groups of C57bl/6 mice and then treated with PBS, MSCs and IFN-γ-treated MSCs. The EAE manifestations were registered daily and finally, the brain and spinal cords were isolated for histopathological and gene expression studies. RESULTS The clinical scores were lowered in MSCs and IFN-γ-licensed MSCs groups, however, mice treated with IFN-γ-licensed MSCs exhibited lower clinical scores than MSCs-treated mice. Leukocyte infiltration into the brain was reduced after treatment with MSCs or IFN-γ-licensed MSCs compared to untreated group (P<0.05 and P<0.01, respectively). In comparison with untreated EAE mice, treatment with MSCs reduced CCL20 expression (P<0.001) and decreased CXCR3 and CCR6 expression (P<0.02 and P<0.04, respectively). In comparison with untreated EAE mice, treatment with IFN-γ-licensed MSCs reduced CXCL10, CCL17 and CCL20 expression (P<0.05, P<0.05, and P<0.001, respectively) as well as decreased CXCR3 and CCR6 expression (P<0.002 and P<0.02, respectively), whilst promoting expression of CCL22 and its receptor CCR4 (P<0.0001 and P<0.02, respectively). In comparison with MSC-treated group, mice treated with IFN-γ-licensed MSCs exhibited lower CXCL10 and CCR6 expression (P<0.002 and P<0.01, respectively), whereas greater expression of CCL22 and CCR4 (P<0.0001 and P<0.01, respectively). CONCLUSION Priming the MSC with IFN-γ can be an efficient approach to enhance the immunomodulatory potential of MSCs.

Abstract
BACKGROUND There is growing evidence linking low levels of vitamin D3 to an increased risk of many autoimmune diseases. Compared to the general population, hypovitaminosis D is more prevalent among children with systemic lupus erythematosus (SLE), which can be associated with sun exposure avoidance, long-term corticosteroid treatment, and renal disease. Therefore, we launched this study to assess the correlation between 25 (OH) D3 (VitD3) levels and the disease activity of children with SLE (cSLE) in Taiwan. METHODS From September to December 2018, we recruited 31 cSLE patients from the Pediatric Out-patient Department of Taichung Veterans General Hospital. Their basic data, including SLE disease index 2000 (SLEDAI-2K) score, laboratory values, prescribed drugs and VitD3 levels were collected and analyzed statistically. RESULTS The mean serum VitD3 concentration was 19.7 ± 7.9 ng/mL and SLEDAI-2K 6.2 ± 5.0. Those patients (N = 16) with an SLEDAI-2K≦4 had higher VitD3 levels when compared to those (N = 15) with an SLEDAI-2K>4 (22.9 ± 7.7 vs 16.3 ± 6.7 points, p = 0.020). Five patients not taking systemic corticosteroids (SCS) had significantly higher VitD3 levels and lower SLEDAI-2K than those who took SCS (N = 26). Additionally, we found VitD3 levels to be negatively correlated to SLEDAI-2K (rs = -0.55, p = 0.001) and daily SCS dosages (rs = -0.49, p = 0.005). CONCLUSION This study shows that VitD3 deficiency is common in patients with cSLE. It was also noted that serum VitD3 levels negatively correlate to SLEDAI-2K, which can be partially explained by less usage of SCS.

Abstract
Multiple sclerosis is an autoimmune treatable but not curable disease. There are a multiplicity of medications for multiple sclerosis therapy, including a class entitled disease-modifying drugs that are mainly indicated to reduce the number and severity of disease relapses. Not all patients respond well to these therapies, and minor to severe adverse effects have been reported. Vitamin D, called sunshine vitamin, is being studied as a possible light at the end of the tunnel. In this review, we recapitulated the similar immunopathogenesis of multiple sclerosis and experimental autoimmune encephalomyelitis, the immunomodulatory and neuroprotective potential of vitamin D and the state-of-art concerning its supplementation to multiple sclerosis patients. Finally, based on our and other groups’ experimental findings, we analyzed the need to consider the relevance of the route and the different time-point administration aspects for a more rational indication of this vitamin to multiple sclerosis patients.

Abstract
Multiple sclerosis is a multifactorial disease of the central nervous system with both genetic and environmental causes. The exact disease mechanisms are still unclear. Consequently, studies of possible treatment and preventive measures cover a large setting of heterogeneous approaches. Vitamin D is one of these approaches, and in many trials the relation of vitamin D serum levels and multiple sclerosis disease risk and activity describes different effects with sometimes inconsistent findings. Animal models are substantial for the research of disease mechanisms, and many of the drugs that are currently in use in multiple sclerosis have been developed, tested, or validated via animal studies. Especially when clinical studies show contradicting findings, the use of standardized settings and information about the mechanistic background is necessary. For this purpose, animal models are an essential tool. There is a variety of different experimental settings and types of animal models available, each of them with own strengths but also weaknesses. This mini-review aims to overview results of vitamin D studies in different animal models and sums up the most important recent findings.

Abstract
Studies on the role of nutritional factors and physical activity (PA) in the pathogenesis of multiple sclerosis (MS) go back a long time. Despite the intrinsic difficulty of studying their positive or negative role in MS, the interest of researchers on these topics increased during the last few decades, since the role of diet has been investigated with the perspective of the association with disease-modifying drugs (DMD). The association of DMD, diets, and PA might have an additive effect in modifying disease severity. Among the various diets investigated (low-carbohydrate, gluten-free, Mediterranean, low-fat, fasting-mimicking, and Western diets) only low-carbohydrate, Mediterranean, and fast-mimicking diets have shown both in animal models and in humans a positive effect on MS course and in patient-reported outcomes (PROs). However, the Mediterranean diet is easier to be maintained compared to fast-mimicking and low-carbohydrate diets, which may lead to detrimental side effects requiring careful clinical monitoring. Conversely, the Western diet, which is characterized by a high intake of highly saturated fats and carbohydrates, may lead to the activation of pro-inflammatory immune pathways and is therefore not recommended. PA showed a positive effect both in animal models as well as on disease course and PROs in humans. Training with combined exercises is considered the more effective approach.

Abstract
Patients with psoriasis (Pso) and, in particular, psoriatic arthritis (PsoA) have an increased risk of developing osteoporosis (OP). It has been shown that OP is among the more common pathologies associated with Pso, mainly due to the well-known osteopenizing conditions coexisting in these patients. Pso and OP share common risk factors, such as vitamin D deficiency and chronic inflammation. Interestingly, the interleukin (IL)-33/ST2 axis, together with vitamin D, is closely related to both Pso and OP. Vitamin D and the IL-33/ST2 signaling pathways are closely involved in bone remodeling, as well as in skin barrier pathophysiology. The production of anti-osteoclastogenic cytokines, e.g., IL-4 and IL-10, is promoted by IL-33 and vitamin D, which are stimulators of both regulatory and Th2 cells. IL-33, together with other Th2 cytokines, shifts osteoclast precursor differentiation towards macrophage and dendritic cells and inhibits receptor activator of nuclear factor kappa-B ligand (RANKL)-induced osteoclastogenesis by regulating the expression of anti-osteoclastic genes. However, while the vitamin D protective functions in OP and Pso have been definitively ascertained, the overall effect of IL-33 on bone and skin homeostasis, because of its pleiotropic action, is still controversial. Emerging evidence suggests a functional link between vitamin D and the IL-33/ST2 axis, which acts through hormonal influences and immune-mediated effects, as well as cellular and metabolic functions. Based on the actions of vitamin D and IL-33 in Pso and OP, here, we hypothesize the role of their crosstalk in the pathogenesis of both these pathologies.

Abstract
While an appropriately regulated production of interferons (IFNs) performs a fundamental role in the defense against coronaviruses such as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), dysregulated overproduction of inflammatory mediators can play an important role in the development of SARS-CoV-2 infection-related complications, such as acute respiratory distress syndrome. As the principal constituents of innate immunity, both type I and III IFNs share antiviral features. However, important properties, including preferential expression at mucosal barriers (such as respiratory tract), local influences, lower receptor distribution, smaller target cell types, noninflammatory effects, and immunomodulatory impacts, were attributed only to type III IFNs. Accordingly, type III IFNs can establish an optimal effective antiviral response, without triggering exaggerated systemic inflammation that is generally attributed to the type I IFNs. However, some harmful effects were attributed to the III IFNs and there are also major differences between human and mouse concerning the immunomodulatory effects of III IFNs. Here, we describe the differential properties of type I and type III IFNs and present a model of IFN response during SARS-COV-2 infection, while highlighting the superior potential of type III IFNs in COVID-19.

Abstract
Infection with the same species of Leishmania (L)donovani causes different manifestations including visceral leishmaniasis (VL) and post kala-azar dermal leishmaniasis (PKDL), indicating that the host-related immunological parameters perform a decisive role in the pathogenesis of diseases. As PKDL is a reservoir of the parasite, a better understanding of the host immune responses is necessary to restrict the L. donovani transmission. The proper local production of Th1 cell-related cytokines (including IFN-γ, TNF-α and IL-12), Th17 cell-derived cytokines (such as IL-17A, IL-17F and IL-22), and CD8+ cytotoxic T lymphocyte (CTL)-derived IFN-γ are protective against PKDL. However, dominant production of regulatory CD4+ T cell-derived cytokines (such as IL-10 and TGF-β), Th2 cell-derived cytokines (such as IL-4/IL-13), M2 macrophage-derived cytokines (such as IL-4 and IL-10), keratinocyte-derived IL-10, regulatory CD8+ T cell-derived IL-10, and dendritic cell-derived IL-10, IL-27 and IL-21 can contribute to the parasite persistence and PKDL development. Understanding of the T cell-related cytokine network within PKDL lesions gives rise to novel insights concerning the role of each cytokine in the protection or susceptibility to disease. Manipulation of the cytokine network can be considered as an interesting immunotherapeutic strategy for the treatment of L. donovani-mediated PKDL.

Abstract
Multiple sclerosis (MS) is an inflammatory demyelinating disease of the central nervous system. We review the two core MS features, myelin instability, fragmentation, and remyelination failure, and dominance of pathogenic CD4+ Th17 cells over protective CD4+ Treg cells. To better understand myelin pathology, we describe myelin biosynthesis, structure, and function, then highlight stearoyl-CoA desaturase (SCD) in nervonic acid biosynthesis and nervonic acid's contribution to myelin stability. Noting that vitamin D deficiency decreases SCD in the periphery, we propose it also decreases SCD in oligodendrocytes, disrupting the nervonic acid supply and causing myelin instability and fragmentation. To better understand the distorted Th17/Treg cell balance, we summarize Th17 cell contributions to MS pathogenesis, then highlight how 1,25-dihydroxyvitamin D3 signaling from microglia to CD4+ T cells restores Treg cell dominance. This signaling rapidly increases flux through the methionine cycle, removing homocysteine, replenishing S-adenosyl-methionine, and improving epigenetic marking. Noting that DNA hypomethylation and inappropriate DRB1*1501 expression were observed in MS patient CD4+ T cells, we propose that vitamin D deficiency thwarts epigenetic downregulation of DRB1*1501 and Th17 cell signature genes, and upregulation of Treg cell signature genes, causing dysregulation within the CD4+ T cell compartment. We explain how obesity reduces vitamin D status, and how estrogen and vitamin D collaborate to promote Treg cell dominance in females. Finally, we discuss the implications of this new knowledge concerning myelin and the Th17/Treg cell balance, and advocate for efforts to address the global epidemics of obesity and vitamin D deficiency in the expectation of reducing the impact of MS.

Abstract
Summarize the study of the role of chemokines and their receptors in multiple sclerosis (MS) patients and MS animal models. Discuss their potential significance in inflammatory injury and repair of MS. Summarize the progress in the research of MS antagonists in recent years with chemokine receptors as targets.
Multiple sclerosis (MS) is a chronic inflammatory disease that is characterized by leukocyte infiltration and subsequent axonal damage, demyelinating inflammation, and formation of sclerosing plaques in brain tissue. The results of various studies in patients indicate that autoimmunity and inflammation make an important impact on the pathogenesis of MS. Chemokines are key mediators of inflammation development and cell migration, mediating various immune cell responses, including chemotaxis and immune activation, and are important in immunity and inflammation, therefore we focus on chemokines and their receptors in multiple sclerosis. In this article, we summarize the study of the role of prominent chemokines and their receptors in MS patients and MS animal modelsand discuss their potential significance in inflammatory injury and repair of MS.

The protective effect of iodide intake adjustment and 1,25(OH) 2D 3 supplementation in rat offspring following excess iodide intake. Ther Adv Endocrinol Metab 2020; 11:2042018820958295. [PMID: 35154633 PMCID: PMC8832296 DOI: 10.1177/2042018820958295] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/17/2019] [Accepted: 08/20/2020] [Indexed: 12/29/2022] Open
Abstract
BACKGROUND In this study, we aimed to investigate the effect of iodide intake adjustment, 1,25(OH)2D3 supplementation, or both, on the thyroid gland of rat offspring. METHODS The offspring of female rats administered 100 times the normal dose of iodide (100 HI; 750 μg/d) during pregnancy and lactation were divided into four different treatment groups. They were either having their iodide intake adjusted from 100 HI to normal iodide intake (7.5 μg/day) or supplemented with 25-hydroxy vitamin D3 [1,25(OH)2D3; 5 μg·kg-1·day-1], or both, for 4 weeks. Thyroid sodium pertechnetate (Na99mTcO4) uptake percentages were measured using single-photon emission computed tomography, while serum levels of free triiodothyronine (FT3), free thyroxine (FT4), thyroglobulin antibody (TgAb), thyroid peroxidase antibody (TPOAb), and vitamin D3 (VD3) were monitored using enzyme-linked immunosorbent assay. The messenger ribonucleic acid expression of interleukin (IL)-17A, interferon gamma (IFN-γ), and IL-10 in the thyroid gland was measured using quantitative real-time polymerase chain reaction, while the protein expression of thyroid-hormone-receptor α1 (TRα1) and thyroid-hormone-receptor β1 (TRβ1) in the thyroid gland was detected using Western blotting. Haematoxylin and eosin (H & E) and immunofluorescence staining were also used to assess thyroid follicular structure and lymphocytic infiltration in the thyroid glands. RESULTS The immunofluorescence staining showed CD4+ co-localized with TRβ1 or the vitamin D receptor in thyroid gland cells of rats that were continuously treated with 100 HI. Following iodide adjustment, 1,25(OH)2D3 supplementation, or both, an increase in serum levels of FT3, free thyroxine, and VD3, protein expression of TRα1 and TRβ1 in the thyroid gland cells, and Na99mTcO4 thyroid uptake percentages was observed. The mRNA expression levels of IL-17A and IFN-γ, decreased, while the mRNA expression levels of IL-10 increased in the thyroid cells of each treatment group, except the group with continuous 100 HI intake. CONCLUSION Iodide adjustment, 1,25(OH)2D3 supplementation, or both may increase the serum levels of FT3, FT4, and VD3, as well as the protein expression levels of TRα1 and TRβ1, in thyroid cells. In addition, iodide adjustment, 1,25(OH)2D3 supplementation, or both, may potentially reverse the imbalance in pro-inflammatory and anti-inflammatory cytokines (IL-17A, IFN-γ, and IL-10) caused by 100 HI, which may be beneficial in improving Na99mTcO4 thyroid uptake percentages.

Abstract
Histamine exerts potent modulatory impacts on the cells of innate- [including neutrophils, monocytes, macrophages, dendritic cells (DCs), natural killer (NK) cells and NKT cells] and adaptive immunity (such as Th1-, Th2-, Th17-, regulatory T-, CD8+ cytotoxic T cells, and B cells) through binding to histamine receptor 2 (H2R). Cimetidine, as an H2R antagonist, reverses the histamine-mediated immunosuppression, as it has powerful stimulatory effects on the effector functions of neutrophils, monocytes, macrophages, DCs, NK cells, NKT cells, Th1-, Th2-, Th17-, and CD8+ cytotoxic T cells. However, cimetidine reduces the regulatory/suppressor T cell-mediated immunosuppression. Experimentally, cimetidine potentiate some immunologic activities in vitro and in vivo. The therapeutic potentials of cimetidine as an immunomodulatory agent were also investigated in a number of human diseases (such as cancers, viral warts, allergic disorders, burn, and bone resorption) and vaccination. This review aimed to provide a concise summary regarding the impacts of cimetidine on the immune system and highlight the cellular mechanisms of action and the immunomodulatory effects of this drug in various diseases to give novel insights regarding the therapeutic potentials of this drug for treatment of immune-related disorders. The review encourages more investigations to consider the immunomodulatory characteristic of cimetidine for managing of immune-related disorders.

Low levels of vitamin D and the relationship between vitamin D and Th2 axis-related cytokines in neuromyelitis optica spectrum disorders. J Clin Neurosci 2019; 61:22-27. [PMID: 30692037 DOI: 10.1016/j.jocn.2018.11.024] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2018] [Accepted: 11/05/2018] [Indexed: 10/27/2022]
Abstract
OBJECTIVE The impact of vitamin D have been studied in neuroinflammation disorders, and as the newly discovered Th2-related cytokines, IL-25, IL-31 and IL-33 may also play important roles in the lesions of neuromyelitis optica spectrum disorders (NMOSD). This study sought to investigate the clinical profiles of vitamin D and Th2 axis-related cytokines and their relationships in patients with NMOSD. METHODS Eighty-four NMOSD patients and 84 healthy controls (HC) were evaluated for serum levels of the total vitamin D [25(OH)D], 25-hydroxyvitamin D2 [25(OH)D2] and 25-hydroxyvitamin D3 [25(OH)D3] by means of high performance liquid chromatographytandem mass spectrometry (HPLC-MS/MS). Meanwhile, serum AQP4-IgG (n = 84) were detected by an AQP4-transfected cell-based assay (CBA) and IL-25, IL-31, IL-33 (n = 32) were performed using enzyme-linked immunoassay (ELISA) method. RESULTS The serum levels of 25(OH)D, 25(OH)D2 and 25(OH)D3 were significantly lower in NMOSD group as compared to HC group. There were also significant differences in serum vitamin D levels between the acute phase group and remission group except the 25(OH)D2 levels (p = 0.070). No correlations were detected between vitamin D and disease activity or vitamin D and disease disability. Furthermore, serum 25(OH)D, 25(OH)D2, and 25(OH)D3 levels were not correlated with serum IL-25, IL-31, and IL-33 levels, the location of lesions and the number of lesion locations. CONCLUSION Our result showed hypovitaminosis D in NMOSD patients. The activity of 25(OH)D3 seemed to be closer to 25(OH)D than 25(OH)D2. Low levels of 25(OH)D/25(OH)D3 might represent a risk factor for the disease activity in patients with NMOSD.

Abstract
Hypovitaminosis D has become a pandemic, being observed in all ethnicities and age groups worldwide. Environmental factors, such as increased air pollution and reduced ultraviolet B (UVB) irradiation, as well as lifestyle factors, i.e., decreased outdoor activities and/or poor intake of vitamin D-rich food, are likely involved in the etiology of a dramatic reduction of vitamin D circulating levels. The insufficiency/deficiency of vitamin D has long been known for its association with osteoporosis and rickets. However, in the last few decades it has become a serious public health concern since it has been shown to be independently associated with various chronic pathological conditions such as cancer, coronary heart disease, neurological diseases, type II diabetes, autoimmune diseases, depression, with various inflammatory disorders, and with increased risk for all-cause mortality in the general population. Prevention strategies for these disorders have recently involved supplementation with either vitamin D2 or vitamin D3 or their analogs at required daily doses and tolerable upper-limit levels. This review will focus on the emerging evidence about non-classical biological functions of vitamin D in various disorders.
