Macrophage inhibitory factor alters the functionality of macrophages and their involvement in disease pathogenesis of active generalized vitiligo patients. Cytokine 2024; 176:156516. [PMID: 38340551 DOI: 10.1016/j.cyto.2024.156516] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2023] [Revised: 01/16/2024] [Accepted: 01/18/2024] [Indexed: 02/12/2024]
Abstract
INTRODUCTION In autoimmune dermatitis patients, a macrophage migration inhibitory factor (MIF) is widely used to determine the severity of the diseases with other clinical parameters. Moreover, in vitiligo, MIF has shown significant positive correlation with the VASI (Vitiligo Area Scoring Index) score of both generalized and localized vitiligo patients. MIF function as pro-inflammatory cytokine and inhibited random migration of macrophages from inflammation loci. Hence, activated macrophage infiltrates promote the diseases pathogenesis. Till date, macrophages and involvement of their secreted MIF in disease severity of vitiligo patients remains undetermined. MATERIAL AND METHOD The frequency of both M1 and M2 macrophages was evaluated in active GV patients (n = 20) using flow cytometry in blood and in tissues by confocal microscopy (n = 10). Relative m-RNA expression and cytokine profiling of pro and anti-inflammatory mediators were estimated in PBMCs and in serum of patients. Lastly, concentration of nitric oxide and phagocytic activity from macrophages of active patients were calculated to understand the diseases pathology in detail. RESULT Both in circulation as well as in tissues, the infiltration of M1 macrophages was increased in active GV patients, while the percentage of M2 macrophages was comparable to healthy tissues. Aberrant expression of pro and anti-inflammatory molecules including IL-1β, IL-6, TNF-α, IL-12 and MIF impair the cellular hemostasis and induce systematic inflammation. Elevated nitric oxide and higher phagocytic activity of macrophages enhanced the destruction and/or depigmentation of melanocytes causing vitiligo. CONCLUSION Elevated macrophages in both tissue and blood enhanced the secretion of MIF and other inflammatory mediators that further enforce the production of nitric oxide, activation and phagocytic activity of macrophages against melanocytes and melanocytes antigens. As a result, destruction of melanocytes and melanin production occurred and caused the depigmentation and/or white macules on the skin.

Abstract
Vitiligo is a chronic skin condition marked by the gradual loss of pigmentation, leading to the emergence of white or depigmented patches on the skin. The exact cause of vitiligo remains not entirely understood, although it is thought to involve a blend of genetic, autoimmune, and environmental factors. While there is currently no definitive cure for vitiligo, diverse treatments exist that may assist in managing the condition and fostering repigmentation in specific instances. Animal models play a pivotal role in comprehending the intricate mechanisms that underlie vitiligo, providing valuable insights into the progression and onset of the disease, as well as potential therapeutic interventions. Although induced experimental models lack the nuanced characteristics observed in natural experimental models, relying solely on a single animal model might not fully capture the intricate pathogenesis of vitiligo. Different animal models simulate specific aspects of human vitiligo pathogenesis to varying degrees. This review extensively explores the array of animal models utilized in vitiligo research, shedding light on their respective advantages, disadvantages, and applications.

Abstract
Introduction Melanocyte dysfunction in vitiligo is considered to be due to genetics, inflammation, and autoimmunity. Research has shown that oxidative stress plays a significant role in triggering these conditions. Currently, there are several markers indicating hematological inflammation and oxidative stress. This study aimed to investigate the status of inflammation and oxidative stress markers in vitiligo. Methods This study included patients with vitiligo and age-gender-matched healthy controls. C-reactive protein (CRP), neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), and monocyte-to-high-density lipoprotein ratio (MHR) and extent of vitiligo were calculated and compared. Results The study included 138 participants (69 vitiligo and 69 controls). The mean was 41.46 years with a female predominance (55.1%). The patient group demonstrated higher levels of platelets, neutrophils, CRP, NLR, MLR, PLR, and HDL and lower levels of lymphocytes and HDL compared to the control group (p>0,05). The only significantly different value between the groups was MHR (p=0.03). The generalized vitiligo group demonstrated higher levels of platelets, neutrophils, monocytes, CRP, NLR, PLR, and MLR, and lower levels of lymphocytes and HDL compared to the localized group. The only significantly different values between the groups were MHR and MLR (p=0.02, p=0.03). Conclusion This study found that MHR and CRP values were higher in vitiligo patients. Additionally, MHR and MLR values were higher in patients with generalized vitiligo. These results suggest that MHR is a reliable indicator marker for systemic inflammation and oxidative stress in vitiligo.

MIF inhibition alleviates vitiligo progression by suppressing CD8 + T cell activation and proliferation. J Pathol 2023; 260:84-96.

Abstract
In vitiligo, autoreactive CD8+ T cells have been established as the main culprit considering its pathogenic role in mediating epidermal melanocyte-specific destruction. Macrophage migration inhibitory factor (MIF) is a pleiotropic molecule that plays a central role in various immune processes including the activation and proliferation of T cells; but whether MIF is intertwined in vitiligo development and progression and its involvement in aberrantly activated CD8+ T cells remains ill-defined. In this study, we found that MIF was overabundant in vitiligo patients and a mouse model for human vitiligo. Additionally, inhibiting MIF ameliorated the disease progression in vitiligo mice, which manifested as less infiltration of CD8+ T cells and more retention of epidermal melanocytes in the tail skin. More importantly, in vitro experiments indicated that MIF-inhibition suppressed the activation and proliferation of CD8+ T cells from the lymph nodes of vitiligo mice, and the effect extended to CD8+ T cells in peripheral blood mononuclear cells of vitiligo patients. Finally, CD8+ T cells derived from MIF-inhibited vitiligo mice also exhibited an impaired capacity for activation and proliferation. Taken together, our results show that MIF might be clinically targetable in vitiligo treatment, and its inhibition might ameliorate vitiligo progression by suppressing autoreactive CD8+ T cell activation and proliferation. © 2023 The Pathological Society of Great Britain and Ireland.

Abstract
Objective The aim of the present study was to investigate the association of single-nucleotide polymorphisms (SNPs) in the macrophage migration inhibiting factor (MIF), interferon-induced Helicase C domain 1 (IFIH1), interleukin-6 (IL6) genes, circulating levels with non-segmental vitiligo (NSV) susceptibility in the Chinese population, and to analyze the relationships between gene polymorphisms and clinical characteristics of vitiligo. Methods In this study, genotyping was conducted in 155 patients with NSV and 117 unaffected controls using polymerase chain reaction and snapshot technique. Serum concentrations were determined by ELISA kit. Results There were strong associations between IFIH1 H843R and IL6-572G/C polymorphisms and NSV susceptibility (p = 0.013; p = 0.009). In contrast to previous studies, we found no significant difference in the MIF-173G/C polymorphism between the two groups. In addition, the frequency of allelic distribution for MIF-173G/C in patients with active NSV was significantly higher than stable NSV (p = 0.011), and IFIH1 H843R with early-onset (≤ 20), active or family history of NSV was significantly higher than late-onset (> 20), stable or no family history of NSV (p = 0.033; p = 0.045; p = 0.039). Serum concentrations of MIF were higher in patients with active NSV, serum IFIH1 and IL6 concentrations were related to the presence of polymorphisms in patients with NSV (p = 0.009; p = 0.011). Conclusion Our results suggested that IFIH1 H843R and IL6-572G/C gene polymorphisms and expression levels are obviously correlated with the onset of NSV. MIF-173G/C allele and serum concentrations may be associated with active NSV, and IFIH1 H843R allele may be associated with youth, active or family history of NSV.

Abstract
Surgical treatments for vitiligo are a safe and effective treatment modality for select patients with vitiligo. Many techniques of vitiligo surgery exist, each with unique advantages and disadvantages. We reviewed the various surgical therapies and innovative approaches for vitiligo regenerative treatment reported in the literature. Surgical therapies can be subdivided into tissue grafting methods and cellular grafting methods. Tissue grafting methods mainly include mini punch grafts, suction blister roof grafts, and hair follicle grafts. Cellular grafting methods include cultured and non-cultured treatments. The efficacy needs to be improved largely due to the poor proliferation and quality of the autologous melanocytes. Rho-associated protein kinase inhibitor enhances primary melanocyte culture proliferation from vitiligo patients to prevent apoptosis. Innovative approaches using stem cell methods could prove invaluable in developing a novel cell therapy for patients suffering from vitiligo. We succeeded in inducing melanin pigmentation in mice skin in vivo using our human induced pluripotent stem cell-derived melanocytes. In addition, we reviewed melanocytorrhagy, detachment and transepidermal loss of melanocytes, and melanocyte-related adhesion molecules. These adhesion molecules include epithelial cadherin, discoidin domain receptor tyrosine kinase 1, glycoprotein non-metastatic melanoma protein B, macrophage migration inhibiting factor, 17β-hydroxysteroid dehydrogenase 1, and E26 transformation-specific 1.

Abstract
Macrophage migration inhibitory factor (MIF) is a proinflammatory cytokine encoded within a functionally polymorphic genetic locus. MIF was initially recognized as a cytokine generated by activated T cells, but in recent days it has been identified as a multipotent key cytokine secreted by many other cell types involved in immune response and physiological processes. MIF is a highly conserved 12.5 kDa secretory protein that is involved in numerous biological processes. The expression and secretion profile of MIF suggests that MIF to be ubiquitously and constitutively expressed in almost all mammalian cells and is vital for numerous physiological processes. MIF is a critical upstream mediator of host innate and adaptive immunity and survival pathways resulting in the clearance of pathogens thus playing a protective role during infectious diseases. On the other hand, MIF being an immune modulator accelerates detrimental inflammation, promotes cancer metastasis and progression, thus worsening disease conditions. Several reports demonstrated that genetic and physiological factors, including MIF gene polymorphisms, posttranslational regulations, and receptor binding control the functional activities of MIF. Taking into consideration the multi-faceted role of MIF both in physiology and pathology, we thought it is timely to review and summarize the expressional and functional regulation of MIF, its functional mechanisms associated with its beneficial and pathological roles, and MIF-targeting therapies. Thus, our review will provide an overview on how MIF is regulated, its response, and the potency of the therapies that target MIF.

Abstract
The skin is our largest organ and the outermost protective barrier. Its aging reflects both intrinsic and extrinsic processes resulting from the constant insults it is exposed to. Aging in the skin is accompanied by specific epigenetic modifications, accumulation of senescent cells, reduced cellular proliferation/tissue renewal, altered extracellular matrix, and a proinflammatory environment favoring undesirable conditions, including disease onset. Macrophages (Mφ) are the most abundant immune cell type in the skin and comprise a group of heterogeneous and plastic cells that are key for skin homeostasis and host defense. However, they have also been implicated in orchestrating chronic inflammation during aging. Since Mφ are related to innate and adaptive immunity, it is possible that age-modified skin Mφ promote adaptive immunity exacerbation and exhaustion, favoring the emergence of proinflammatory pathologies, such as skin cancer. In this review, we will highlight recent findings pertaining to the effects of aging hallmarks over Mφ, supporting the recognition of such cell types as a driving force in skin inflammaging and age-related diseases. We will also present recent research targeting Mφ as potential therapeutic interventions in inflammatory skin disorders and cancer.

Abstract
Multiple factors are involved in the process leading to melanocyte loss in vitiligo including environmental triggers, genetic polymorphisms, metabolic alterations, and autoimmunity. This review aims to highlight current knowledge on how danger signals released by stressed epidermal cells in a predisposed patient can trigger the innate immune system and initiate a cascade of events leading to an autoreactive immune response, ultimately contributing to melanocyte disappearance in vitiligo. We will explore the genetic data available, the specific role of damage-associated-molecular patterns, and pattern-recognition receptors, as well as the cellular players involved in the innate immune response. Finally, the relevance of therapeutic strategies targeting this pathway to improve this inflammatory and autoimmune condition is also discussed.

Abstract
Vitiligo is a common immune-related depigmentation condition, and its pathogenesis remains unclear. This study used a combination of bioinformatics methods and expression analysis techniques to explore the relationship between immune cell infiltration and gene expression in vitiligo. Previously reported gene expression microarray data from the skin (GSE53146 and GSE75819) and peripheral blood (GSE80009 and GSE90880) of vitiligo patients and healthy controls was used in the analysis. R software was used to filter the differentially expressed genes (DEGs) in each dataset, and the KOBAS 2.0 server was used to perform functional enrichment analysis. Compared with healthy controls, the upregulated genes in skin lesions and peripheral blood leukocytes of vitiligo patents were highly enriched in immune response pathways and inflammatory response signaling pathways. Immunedeconv software and the EPIC method were used to analyze the expression levels of marker genes to obtain the immune cell population in the samples. In the lesional skin of vitiligo patients, the proportions of macrophages, B cells and NK cells were increased compared with healthy controls. In the peripheral blood of vitiligo patients, CD8+ T cells and macrophages were significantly increased. A coexpression analysis of the cell populations and DEGs showed that differentially expressed immune and inflammation response genes had a strong positive correlation with macrophages. The TLR4 receptor pathway, interferon gamma-mediated signaling pathway and lipopolysaccharide-related pathway were positively correlated with CD4+ T cells. Regarding immune response-related genes, the overexpression of IFITM2, TNFSF10, GZMA, ADAMDEC1, NCF2, ADAR, SIGLEC16, and WIPF2 were related to macrophage abundance, while the overexpression of ICOS, GPR183, RGS1, ILF2 and CD28 were related to CD4+ T cell abundance. GZMA and CXCL10 expression were associated with CD8+ T cell abundance. Regarding inflammatory response-related genes, the overexpression of CEBPB, ADAM8, CXCR3, and TNIP3 promoted macrophage infiltration. Only ADORA1 expression was associated with CD4+ T cell infiltration. ADAM8 and CXCL10 expression were associated with CD8+ T cell abundance. The overexpression of CCL18, CXCL10, FOS, NLRC4, LY96, HCK, MYD88, and KLRG1, which are related to inflammation and immune responses, were associated with macrophage abundance. We also found that immune cells infiltration in vitiligo was associated with antigen presentation-related genes expression. The genes and pathways identified in this study may point to new directions for vitiligo treatment.

Abstract
BACKGROUND: Alopecia areata and vitiligo vulgaris are common autoimmune diseases whose pathophysiology are not completely elucidated. Genetic susceptibility, immunological background, and stress have significant roles in their pathogenesis. Although macrophage migration inhibitory factor (MIF) is crucial for the maintenance of immune privilege in certain sites, it can upregulate different inflammatory cytokines and contribute to the pathogenesis of different autoimmune diseases. There is controversy about its role in alopecia and no adequate data about its role in vitiligo. OBJECTIVES: We sought to assess the serum level of MIF in alopecia areata and vitiligo and its relationship with different variables of both diseases. METHOD: Serum level of MIF was measured in 20 patients with vitiligo, 22 patients with alopecia areata, and 20 controls by ELISA. RESULTS: MIF was significantly higher in alopecia areata (8.477±4.1761ng/mL) and vitiligo vulgaris (3.930±2.7071ng/mL) compared to controls (0.725±0.5108 ng/mL) (P<0.01). In addition, MIF levels were positively correlated with the severity of alopecia areata and vitiligo. CONCLUSION: The MIF has an active role in the pathogenesis of alopecia areata and vitiligo and could be a target for the treatment of both diseases.

Macrophage inhibitory factor (MIF) gene polymorphisms are associated with disease susceptibility and with circulating MIF levels in active non-segmental vitiligo in patients from western Mexico. Mol Genet Genomic Med 2020; 8:e1416. [PMID: 32705792 PMCID: PMC7549602 DOI: 10.1002/mgg3.1416] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2020] [Revised: 06/08/2020] [Accepted: 07/01/2020] [Indexed: 12/17/2022] Open
Abstract
Background The macrophage migration inhibiting factor (MIF) is a protein that promotes the activation of immune cells and the production of other proinflammatory cytokines such as TNF‐α, IL‐1β, and IFN‐γ, which have proposed to play an essential role in the pathogenesis of vitiligo. The study aimed to assess the association between MIF polymorphisms (−794 CATT5‐8 and −173 G>C), MIF in situ expression, and MIF serum concentrations with susceptibility and disease activity in patients with non‐segmental vitiligo (NSV) from western Mexico. Methods The study included 111 patients with NSV and 201 control subjects. Genotyping was performed by conventional PCR (−794 CATT5‐8) and PCR‐RFLP (−173 G>C) methods. MIF mRNA expression was quantified by real‐time PCR and MIF serum concentrations were determined by ELISA kit. Histopathological samples were analyzed by automated immunohistochemistry. Results The MIF polymorphisms were associated with NSV susceptibility. Serum concentrations of MIF were higher in patients with active NSV and correlated negatively with the years of evolution. The depigmented skin from patients with active vitiligo showed a high expression of MIF. Conclusion MIF polymorphisms increase the risk of NSV in the western Mexican population. The serum concentrations of MIF and in situ expression are associated with active NSV.
