Abstract
Several auto-immune diseases have been linked to vitamin D deficiency as a contributing environmental factor. Its pleiotropic effects on the immune system, especially its essential role in maintaining immune tolerance, make the vitamin D pathway of great interest. In this study, we focused on Pemphigus foliaceous (PF) in Tunisian population. we aimed to quantify the Serum 25[OH]D levels using chemiluminescence assay and to analyze the differential expression of the VDR, CYP27B1 and CYP24A1 genes in the circulating blood cells and lesional skin tissue of PF patients using Q-PCR. A genetic explanation was then sought to explore any direct relationship between tag polymorphisms and the inherited features of PF. Results confirmed a vitamin D hypovitaminosis in Tunisian PF patients. Interestingly, a differential gene expression correlated to the disease stratification was noted. Indeed, at the systemic level, an upregulation of VDR and CYP27B1 genes was observed in healthy controls compared to PF patients. Notably, in lesional skin tissue, the clinical and serological remission phase was correlated with high transcriptional levels of the VDR gene and conversely a drop in expression of the CYP24A1 gene. Genetic analysis indicated the involvement of the most appealing polymorphisms, rs2228570 and poly (A) microsatellite, in PF etiopathogenesis. Indeed, CAC13 haplotype was associated with a higher risk of PF development. Our findings suggest that alterations in the vitamin D-VDR pathway may influence PF physiopathology, making this pathway a potential target for pharmacological modulation, especially for cortico-resistant PF patients.

Abstract
BACKGROUND The inflammatory factor interferon (IFN)-γ is related to the occurrence and development of systemic lupus erythematosus (SLE). The vitamin D receptor (VDR) has an anti-inflammatory effect and its downregulation is involved in the onset of SLE. Our previous studies have confirmed that the expression of VDR in SLE peripheral blood mononuclear cells (PBMCs) is downregulated, which is negatively correlated with disease activity and inflammation. However, the mechanism underlying VDR downregulation in SLE is unknown. METHODS Based on the results of computer simulation analysis, the expression of VDR and four microRNAs (miR-17-3p, miR-34a, miR-346, and miR-125b) in SLE PBMC cells was analyzed under proinflammatory cytokine IFN‑γ treatment, and miR-125b was identified as the target miRNA. The relationship between IFN‑γ, miR-125b, and VDR was further assessed in THP‑1 cells. RESULTS We showed that IFN‑γ inhibited the expression of VDR and miR-125b. Further study revealed that VDR mRNA was positively correlated with miR-125b in THP‑1 cells after IFN‑γ intervention. After transfection of miR-125b mimic or inhibitor, the expression of VDR in the miR-125b inhibitor group was lower than in the control group and miR-125b mimic group, while expression in the control group was lower than in miR-125b mimic group. Transfection of miR-125b inhibitor into THP‑1 cells could further promote the ability of IFN‑γ to inhibit VDR. CONCLUSION The decrease in VDR expression promotes development of inflammation and SLE. These data suggest that miR-125b may mediate inflammatory factor IFN-γ-induced downregulation of VDR in the pathogenesis of SLE.

Abstract
Abstract
Background
Lung cancer (LC) is one of the leading causes of death worldwide. Programmed cell death receptor 1 (PD-1) interacts with its ligand (PDL-1) on T cells inhibiting its functioning which may affect the patient's immunological response.
Aim
Investigate if there is a link between smoking and tissue expression of PDL-1 and vitamin D receptor (VDR) in lung cancer patients. In addition, the relation of vitamin D with smoking and these biochemical markers.
Methods
PDL-1 and VDR expressions were evaluated by real-time PCR in 54 lung cancer biopsy samples and 36 controls to prove this hypothesis. Vitamin D levels in the blood were measured using an ELISA.
Results
Expressions of PDL-1 were significantly upregulated in LC patients than in controls. The highest expression was in stage II and in squamous cell carcinoma followed by small cell carcinoma then adenocarcinoma. However, VDR expressions and vitamin D levels in serum were significantly downregulating in LC patients than in controls. There was a positive correlation between PDL-1expression and duration of smoking but not smoking index. Also, there is an inverse correlation between duration of smoking, smoking index, and VDR.
Conclusion
Expression of PDL-1 in LC was significantly upregulated and correlated with staging. Interestingly, our current study for the first time explained the role of duration of smoking on PDL-1 and VDR in the pathogenesis of LC. As PDL-1 expression increased with duration of smoking whereas VDR decreased, this novel findings may provide a possible link between the cumulative effect of smoking and the level of expressions of these biomarkers.

Decreased inflammatory gene expression accompanies the improvement of liver enzyme and lipid profile following aerobic training and vitamin D supplementation in T2DM patients. BMC Endocr Disord 2022; 22:245.

Abstract
BACKGROUND Type 2 Diabetes Mellitus (T2DM) is one of the health issues causing untoward low-grade systemic inflammation. Aerobic Training (AT) and Vitamin D (Vit D) supplementation are among the approaches that improve lipid profile and liver enzymes in T2DM. However, the mechanisms responsible for these improvements are not fully elucidated. OBJECTIVES This study aimed to evaluate the effects of AT and Vit D supplementation on lipid profile, liver enzymes, Interleukin-6 (IL-6), Interleukin-10 (IL-10), Cluster of differentiation 27 (CD27), Chemokine (C-X-C motif) Ligand 13 (CXCL13), Interferon-Gamma (IFN-γ) and Transforming Growth Factor-Beta 1 (TGF-β1) gene expressions in patients with T2DM. METHODS In this study, 40 male T2DM patients aged 35-50 years were randomly selected and assigned into four groups (n = 10 for each); AT+vitamin D supplementation (AT+Vit D), AT+placebo (AT), Vit D supplementation (Vit D), and control+placebo (C). The intervention consisted of 8 weeks of 20-40 minutes AT protocol at 60-75% HRmax 3 sessions/week and taking 50,000 IU of Vit D supplement once a week. Serum levels of lipid profile and liver enzymes and gene expression of IL-6, IL-10, CD27, CXCL13, IFN-γ, and TGF-β1 in Peripheral Blood Mononuclear Cells (PBMCs) were measured. One-way analysis of variance (ANOVA), Tukey's post hoc, and paired sample t-test at P-values less than 0.05 were used to analyze the data using SPSS software. RESULTS AT+Vit D, AT, and Vit D significantly decreased TC, TG, LDL, AST, ALT, and GGT while increased HDL after 8 weeks in favor of AT+Vit D. Also, gene expressions of IL-6, IL-10, CD27, CXCL13, IFN-γ, and TGF-β1 were downregulated significantly in AT+Vit D, AT, and Vit D, while upregulated in C. Furthermore, compared to individual AT or Vit D, AT+Vit D significantly downregulated IL-6 (P = 0.013; P = 0.025), IL-10 (P = 0.012; P = 0.026), CD27 (P = 0.023; P = 0.041), CXCL13 (P = 0.014; P = 0.025), IFN-γ (P = 0.017; P = 0.026), and TGF-β1 (P = 0.001; P = 0.028). CONCLUSION In comparison to individual AT or Vit D, AT+Vit D may enhance lipid profile, and liver enzymes and drive the balance to favor inhibition of inflammation by downregulating gene expression of inflammation-related factors. As a result, AT+Vit D may be considered appropriate therapy for managing T2DM.

Abstract
Active vitamin D is a true steroid hormone with pleiotropic biological effects that go beyond the classical concept of bone metabolism regulation. In fact, adequate serum levels of 25-hydroxyvitamin D (>40 ng/mL) are required to support several biological functions, including the control of innate and adaptive immunity in course of infectious, inflammatory and autoimmune diseases. SARS-CoV-2 is responsible for the COVID-19 pandemic and deficient/insufficient serum levels of 25-hydroxyvitamin D are reported in very large cohorts of patients. Of note, vitamin D is involved in different pathophysiological processes, such as expression of SARS-CoV-2 receptor (ACE2), activation of innate (neutrophils with their extracellular traps, monocytes/macrophages, dendritic cells, natural killer cells) and adaptive (T and B lymphocytes) immune cells and clinical manifestations, such as coagulation/thrombotic disorders and acute respiratory distress syndrome. Randomized clinical trials regarding vitamin D supplementation in COVID-19 patients have shown favorable effects on the control of inflammation markers, arterial oxygen saturation/inspired fraction of oxygen ratio, admission to hospital intensive care units and mortality. A target of serum 25-hydroxyvitamin D > 50 ng/mL has been identified as protective for the course of COVID-19, potentially playing an ancillary role in the treatment of the disease.

Abstract
Immune cells, including dendritic cells, macrophages, and T and B cells, express the vitamin D receptor and 1α-hydroxylase. In vitro studies have shown that 1,25-dihydroxyvitamin D, the active form of vitamin D, has an anti-inflammatory effect. Recent epidemiological evidence has indicated a significant association between vitamin D deficiency and an increased incidence, or aggravation, of infectious diseases and inflammatory autoimmune diseases, such as rheumatoid arthritis, systemic lupus erythematosus, and multiple sclerosis. However, the impact of vitamin D on treatment and prevention, particularly in infectious diseases such as the 2019 coronavirus disease (COVID-19), remains controversial. Here, we review recent evidence associated with the relationship between vitamin D and inflammatory diseases and describe the underlying immunomodulatory effect of vitamin D.

Abstract
OBJECTIVES Systemic lupus erythematosus (SLE) is characterised by accumulated cell apoptosis. Vitamin D receptor (VDR) has immunomodulatory effect and potent anti-apoptosis activities. The aim of this study was to examine the correlation between CD4+T cells VDR expression, cell apoptosis, and disease activity in patients with SLE. METHODS Forty-five SLE patients were recruited and 50 healthy individuals served as controls. The expression of VDR in CD4+T cells and their subsets were determined by flow cytometry. The correlations between VDR expression and cell apoptosis or disease parameters in SLE patients were analysed. RESULTS VDR expression in CD4+T cells and their subsets were upregulated in SLE patients, especially in help T (Th)1, regulatory T (Treg), and follicular helper T (Tfh) cells. Frequency of VDR-positive CD4+T cells was positively associated with SLE disease activity index (SLEDAI)-2K values and inversely correlated with serum C3 concentration. The frequency of VDR-positive CD4+T cells, Th1 cells, Th2 cells, Th17 cells, Treg cells, and Tfh cells was positively correlated with cells apoptosis. CONCLUSION VDR expression in CD4+T cells and their subsets were increased in SLE. VDR expression was positively associated with disease activity and cell apoptosis in SLE patients.

Abstract
Vitamin D is synthesized in the skin following exposure to UVB radiation or is directly absorbed from the diet. Following hydroxylation in the liver and kidneys, vitamin D becomes its bioactive form, 1,25(OH)2D, which has been described to have potent immunomodulatory capacity. This review will focus on the effect of vitamin D in modulating the dysregulated immune system of autoimmune rheumatic diseases (ARD) patients across age, in particular in arthritis (rheumatoid arthritis and juvenile idiopathic arthritis), and systemic lupus erythematosus (with adult and juvenile onset). As well as delineating the impact of vitamin D on the innate and adaptive immune functions associated with each disease pathology, this review will also summarize and evaluate studies that link vitamin D status with disease prevalence, and supplementation studies that examine the potential benefits of vitamin D on disease outcomes. Exploring this evidence reveals that better designed randomized controlled studies are required to clarify the impact of vitamin D supplementation on ARD outcomes and general health. Considering the accessibility and affordability of vitamin D as a therapeutic option, there is a major unmet need for evidence-based treatment recommendations for the use of vitamin D in this patient population.

Abstract
The vitamin D receptor (VDR) plays an important role in the pathogenesis of systemic lupus erythematosus (SLE) mainly due to its anti-inflammatory and immunomodulatory activities. Interferon-inducible protein-10 (IP-10) is a chemokine found to be increased in SLE patients and correlated with severity of lupus nephritis. In this case control study, we investigated the connection between VDR expression and chemokine IP-10 in peripheral blood mononuclear cells (PBMCs) of SLE patients with or without renal involvement. 62 SLE patients and 30 healthy subjects were enrolled between 2014 and 2016. PBMC VDR mRNA and IP-10 mRNA were quantified by real-time PCR. PBMC VDR protein was measured by Western blotting. PBMC VDR mRNA and protein were downregulated, whereas IP-10 mRNA was upregulated in SLE patients with renal involvement. VDR mRNA levels were negatively correlated with systemic lupus international collaborating clinics (SLICC) renal activity scores (r = −0.423, P = 0.016) and IP-10 mRNA levels (r = −0.428, P = 0.008) in SLE with renal involvement. This study demonstrates that PBMC VDR was negatively correlated with SLICC renal activity and chemokine IP-10 in SLE patients with renal involvement which suggests that VDR downregulation may be used as an indicator of renal injury in SLE patients.

Abstract
Systemic lupus erythematosus (SLE) is a chronic autoimmune disease and hypocomplementemia signifies disease activity. Several studies have shown that calcium may help maintain optimum function of immune system and metabolism in SLE. The aim of our study was to analyze the relationship between total serum calcium level and SLE activity. A total of 66 patients with SLE and 214 healthy controls were included in this study. Our results showed lower serum levels of calcium (P < .001), complement C3 (P < .001), complement C4 (P < .001), and albumin (P < .001) in patients with SLE. A negative correlation was found between serum calcium level and systemic lupus erythematosus disease activity index (SLEDAI) rating (r = -0.394, P = .001). Additionally, serum level of calcium was positively correlated with serum complement C3 level (r = 0.366, P = .003) in patients with SLE, while no such correlation was found between serum calcium level and complement C4 (r = -0.190, P = .126). Likewise, patients with SLE with normal serum calcium level showed higher complement C3 level (P < .01) than that of patients with low serum calcium level. Overall, the results displayed that patients with SLE have lower serum calcium level compared to healthy controls, and the serum calcium level is positively correlated with SLEDAI rating and serum complement C3 level in patients with SLE. In conclusion, the total serum calcium level is negatively correlated with SLE disease activity.

Abstract
OBJECTIVE To detect the expressions of vitamin D receptor (VDR) in peripheral blood monocytes (PBMCs) and its association with monocyte chemoattractant protein-1 (MCP-1) in patients with systemic lupus erythemaotsus (SLE). METHODS We examined the expressions of VDR and MCP-1 mRNAs in the PBMCs in 60 SLE patients and 28 healthy individuals using real- time quantitative PCR. We also detected the expression of VDR protein in the PBMCs using Western blotting and peripheral blood MCP-1 level using ELISA for these participants. The correlation of VDR and MCP-1 expressions with the disease activity index of SLE (SLEDAI) of the patients were analyzed. RESULTS The expressions of VDR mRNA and protein in the PBMCs were significantly lower in patients with SLE than in the healthy individuals (P < 0.01), and that in the patients with active disease was lower than in remission (P < 0.05). The MCP-1 mRNA expression in the PBMCs and its serum levels were significantly increased in SLE patients as compared with the healthy individuals (P < 0.01), and the increase was significantly more obvious in the patients with active disease than in those in remission (P < 0.01). Pearson correlation analysis showed that VDR mRNA in the PBMCs was negatively correlated with SLEDAI (r=-0.417, P=0.001); negative correlations were also found between VDR mRNA and MCP-1 mRNA(r=-0.554, P=0.000) and between VDR protein expression and serum MCP-1 level (r=-0.400, P=0.028). CONCLUSIONS The down-regulation of VDR expression in the PBMC is negatively correlated with the disease activity of SLE. VDR may play an important role in the pathogenesis of SLE by affecting the expression of MCP-1.
