Abstract
BACKGROUND Considering the pathogenesis of psoriasis and also the anti-oxidant, immunomodulatory, and anti-inflammatory properties of rosuvastatin and melatonin, the current clinical trial aimed to evaluate the efficacy of topical rosuvastatin and melatonin in patients with mild to moderate psoriasis. METHODS The current randomized placebo-controlled clinical trial was conducted using a 3-arm parallel group included 77 adult patients (≥18 years old) with mild to moderate plaque psoriasis. Patients were randomized into a 1:1:1 ratio to one of three groups to receive one of the three interventions: melatonin cream, 5.0% (w/w), rosuvastatin cream, 5.0% (w/w), or placebo cream with a similar transparent appearance twice a day for 12 weeks. The primary outcome was severity of the disease using Psoriasis Area Severity Index (PASI). The secondary outcomes included the Dermatological Sum Score (DSS) to assess the erythema, scaling, and plaque elevation and the Dermatology Life Quality Index (DLQI). Photographs of the lesions were also taken at the baseline and at different periodic intervals thereafter. RESULTS Among 77 randomized patients, 52 (mean (SD) age, 40.67 (10.85) years; 22 (42.30%) men) completed the study. A significant reduction of 45% (mean (SD) of 2.67 (0.98) to 1.74 (1.12)) and 70% (mean (SD) of 2.67 (0.98) to 1.31 (1.13)) in PASI score, and 46% (mean (SD) of 2.91(1.85) to 1.57 (1.11)) and 77% (mean (SD) of 2.91 (1.85) to 0.87 (0.67)) in DSS score on days 30 and 60 with rosuvastatin cream, 5% w/w (P < 0.001) compared with baseline was observed, respectively. Also a significant decrease of 35% (mean (SD) of 2.67 (0.98) to 1.74 (1.12)) and 51% (mean (SD) of 2.67 (0.98) to 1.31 (1.13)) in PASI score, and 40% (mean (SD) of 5.00 (1.58) to 3.00 (1.76))and 61% (mean (SD) of 5.00 (1.58) to 1.92 (1.71)) in DSS score on days 30 and 60 with melatonin cream, 5% w/w (P < 0.001) compared with baseline were observed, respectively. In each of the melatonin or rosuvastatin groups, DLQI improved significantly on days 30 (P < 0.0001) and 60 (P < 0.001) while the changes in the control group were not significant. CONCLUSION The results of this clinical trial demonstrated that topical melatonin and rosuvastatin diminished the severity of mild to moderate plaque psoriasis with a satisfactory safety profile. Future clinical trials should assess both the long-term efficacy and safety of melatonin and rosuvastatin creams in larger study populations.

Abstract
Psoriasis is a highly prevalent chronic disease associated with a substantial social and economic burden. Oxeiptosis is a programmed cell death that occurs when cells are in a state of high oxidative stress, which has a potent anti-inflammatory effect. However, there is still no research on oxeiptosis in psoriasis, and the agonists or antagonists of oxeiptosis remain an unclear field. Here, we found that oxeiptosis of keratinocytes was inhibited in psoriasis lesions. KEAP1, as the upstream molecular component of oxeiptosis, is highly expressed in psoriasis lesions. Knockdown of KEAP1 in HaCaT cells caused oxeiptosis in the condition of M5 cocktail stimulation. Next, we found that the cell-permeable derivative of itaconate, 4-octylitaconate (OI) promoted oxeiptosis of keratinocytes by inhibiting KEAP1 and then activating PGAM5 which are two upstream molecular components of oxeiptosis. At the same time, OI can reduce the expression of inflammatory cytokines induced by M5 cocktail stimulation in vitro. Similarly, we found that OI can alleviate IMQ-induced psoriatic lesions in mice and downregulate the levels of inflammatory cytokines in psoriatic lesions. In summary, our findings suggest that oxeiptosis of keratinocytes was inhibited in psoriasis and OI can significantly inhibit inflammation and alleviate psoriasis as an agonist of oxeiptosis, indicating that oxeiptosis may be involved in regulating the progression of psoriasis, which may provide new therapeutic targets for psoriasis treatment.

Abstract
In the onset and progression of psoriasis, redox imbalance is a vital factor. It's widely accepted that too much reactive oxygen species (ROS) always make psoriasis worse. Recent research, however, has shown that the accumulation of ROS is not entirely detrimental, as it helps reduce psoriasis lesions by inhibiting epidermal proliferation and keratinocyte death. As a result, ROS appears to have two opposing effects on the treatment of psoriasis. In this review, the current ROS-related therapies for psoriasis, including basic and clinical research, are presented. Additionally, the design and therapeutic benefits of various drug delivery systems and therapeutic approaches are examined, and a potential balance between anti-oxidative stress and ROS accumulation is also trying to be investigated.

Abstract
BACKGROUND Psoriasis is a chronic autoimmune disease impairing significantly the quality of life of the patient. The diagnosis of the disease is done via a visual inspection of the lesional skin by dermatologists. Classification of psoriasis using gene expression is an important issue for the early and effective treatment of the disease. Therefore, gene expression data and selection of suitable gene signatures are effective sources of information. METHODS We aimed to develop a hybrid classifier for the diagnosis of psoriasis based on two machine learning models of the genetic algorithm and support vector machine (SVM). The method also conducts gene signature selection. A publically available gene expression dataset was used to test the model. RESULTS A number of 181 probe sets were selected among the original 54,675 probes using the hybrid model with a prediction accuracy of 100% over the test set. A number of 10 hub genes were identified using the protein-protein interaction network. Nine out of 10 identified genes were found in significant modules. CONCLUSIONS The results showed that the genetic algorithm improved the SVM classifier performance significantly implying the ability of the proposed model in terms of detecting relevant gene expression signatures as the best features.

Abstract
Psoriasis, a complex inflammatory autoimmune skin disorder that affects 2–3% of the global population, is thought to be genetically predetermined and induced by environmental and immunological factors. In the past decades, basic and clinical studies have significantly expanded knowledge on the molecular, cellular, and immunological mechanisms underlying the pathogenesis of psoriasis. Based on these pathogenic mechanisms, the current disease model emphasizes the role of aberrant Th1 and Th17 responses. Th1 and Th17 immune responses are regulated by a complex network of different cytokines, including TNF-α, IL-17, and IL-23; signal transduction pathways downstream to the cytokine receptors; and various activated transcription factors, including NF-κB, interferon regulatory factors (IRFs), and signal transducer and activator of transcriptions (STATs). The biologics developed to specifically target the cytokines have achieved a better efficacy and safety for the systemic management of psoriasis compared with traditional treatments. Nevertheless, the current therapeutics can only alleviate the symptoms; there is still no cure for psoriasis. Therefore, the development of more effective, safe, and affordable therapeutics for psoriasis is important. In this review, we discussed the current trend of therapeutic development for psoriasis based on the recent discoveries in the immune modulation of the inflammatory response in psoriasis.

Abstract
Increasing evidence suggests that long non-coding RNAs (lncRNAs) are of vital importance for various biological processes, and dysregulation of lncRNAs is frequently associated with various diseases such as psoriasis. LncRNAs modulate gene expression at the transcriptional, post-transcriptional, and translational levels; however, the specific regulatory mechanisms of lncRNAs in psoriasis remain largely unexplored. This review provides an overview of recent studies investigating mechanisms and functions of lncRNAs in psoriasis, especially focusing on the role of lncRNAs in keratinocytes, T cells, and dendritic cells.

Abstract
Psoriasis is a chronic inflammatory skin disease in which dendritic cells (DCs) play a pivotal role by inducing Th1/Th17 immune responses; however, the regulation of DC activation in psoriasis remains largely unknown. Previously we found that the level of soluble CD100 was increased in sera of psoriasis patients, and CD100 promoted the activation of inflammasome in keratinocytes. In the present study, CD100 knockout mice were utilized for generation of imiquimod (IMQ)-induced psoriatic dermatitis, with the result that skin inflammation in the early, but not late, phase of the psoriatic dermatitis was significantly exacerbated compared to that in wild-type controls. This was attributed mainly to the deficiency of CD100 in hematopoietic cells. Bone marrow-derived DCs, but not T cells or keratinocytes, from CD100 knockout mice produced significantly increased levels of IL-1β, IL-36, and IL-23 upon stimulation with IMQ in a plexin-B2-dependent manner. Moreover, the surface level of plexin-B2 on DCs of psoriasis patients was lower than that of healthy individuals, and CD100 attenuated IMQ-induced production of IL-1β and IL-36 from monocyte-derived DCs of psoriasis patients. Our results uncovered a negative regulatory mechanism for DCs activation in psoriasis, which was mediated via CD100-plexin-B2 in a cell type- and receptor-specific manner. © 2020 Pathological Society of Great Britain and Ireland.

Abstract
Introduction: The etiopathogenesis of psoriasis is still unclear but there is evidence that many of cytokines released by keratinocytes and inflammatory leukocytes may contribute to the induction or persistence of the inflammatory process in psoriasis. Aim: The aim of the study was to evaluate serum concentrations of Interferon gamma (IFN-γ) in patients with psoriasis and the healthy subjects and also to assess a possible association between IFN-γ, clinical type and severity of disease. Material and Methods: The study included a total of 60 patients with psoriasis and 20 healthy subjects in the control group. According to the clinical type of disease, patients with psoriasis were divided into four groups: psoriasis vulgaris (PV), psoriasis erythrodermica (PE), psoriasis pustulosa (PP) and psoriasis arthropatica (PA). Blood samples were collected from all psoriasis patients and from healthy control subjects. Serum IFN-γ levels were measured by an enzyme-linked immunosorbent assay (ELISA) technique. The severity of PV was assessed by Psoriasis Area and Severity Index (PASI) score. Results: The serum concentration of IFN-γ in patients with psoriasis was significantly higher than that in the control group (1.91±1.79 pg/mL vs 0.91±0.38 pg/mL, respectively). Significantly elevated serum IFN-γ concentrations were noticed in patients with PV (2.15±0.30 pg/mL). There was no statistically significant difference between the mean values of IFN- γ compared to the clinical type of psoriasis (p>0.05). In the group of patients with PV 36 (85.71%) patients had mild form of disease with PASI <50, and 6 (14.29%) patients had severe disease with PASI >50. It was not found statistically significant correlation between serum IFN-γ level and PASI score in the group of PV. Conclusions: The results of our study indicate that psoriasis is associated with significant changes in the serum concentration of IFN-γ. There was no significant correlation between serum IFN-γ concentrations, clinical type of psoriasis and severity of PV evaluated with the use of PASI score.

Abstract
Psoriasis is an autoimmune chronic dermatosis that is T cell-mediated, characterized by epidermal thickening, aberrant epidermal differentiation and inflammatory infiltrates, with a dominant Th1 and Th17 profile. Additional in vitro models are required to study the complex interactions between activated T cells and skin cells, and to develop new, more effective treatments. We have therefore sought to model this psoriatic inflammation by the generation of tissue-engineered immunocompetent tissues, and we have investigated the response of activated T-cell infiltration in models produced with lesional psoriatic skin cells on major hallmarks of psoriasis. The immunocompetent lesional skin model displayed a delayed onset of epidermal differentiation, an hyperproliferation of the basal keratinocytes, a drastic increase in the secretion of proinflammatory cytokines, and a disturbed expression of key transcription factors, as observed in lesional plaques, suggesting a crucial importance of combining the pathological phenotype of cutaneous cells to T cells in order to generate a relevant model for psoriasis. Finally, we found this skin model to be responsive to methotrexate treatment, making it a valuable tool for drug development.

Abstract
Psoriasis is a common inflammatory skin disease mediated by cells and molecules in both the innate and adaptive immune systems. Recently, gene expression profile analysis revealed a large set of immune-related differentially expressed genes (DEGs) in psoriasis. However, the associations between these DEGs and their transcriptional regulation mechanisms have not been completely elucidated. In this study, several psoriasis Gene Expression Omnibus data sets were systematically analyzed using bioinformatics tools to uncover important transcription factors (TFs) that regulate the expression of immune-related DEGs and further enhance our understanding of psoriasis pathogenesis. Common DEGs encoding chemokines, cytokines, antimicrobial peptides, and keratins were identified in psoriasis, and extensive correlations existed among these DEGs. Several common TFs that bind the promoters of the DEGs, including the well-known signal transducer and activator of transcription 1 (STAT1), STAT3, and nuclear factor κ-light-chain-enhancer of activated B cells (NF-κB) as well as ETS homologous factor (EHF), Fos-like antigen 1 (FOSL1), and Forkhead box C1 (FOXC1), which are rarely studied in psoriasis, were also identified. STAT1, EHF, FOSL1, STAT3, and NFKB1 were positively correlated with these DEGs in psoriasis lesions, whereas FOXC1 was negatively correlated with most DEGs. The decreased expression of the DEGs was accompanied by the downregulation of STAT1, EHF, FOSL1, STAT3, and NFKB1 and the upregulation of FOXC1 upon blocking interleukin 17 (IL-17) or tumor necrosis factor α signaling in psoriasis. Additionally, the downregulation of IL37 in psoriasis was negatively correlated with STAT1 and CXCL10, which are associated with Th1 responses. These results suggest that TFs play an important role in the pathogenesis of psoriasis, and interfering with the activity of key TFs may be a promising therapeutic strategy for psoriasis.

Abstract
Psoriasis is a frequent chronic inflammatory skin disease, nowadays considered a major global health problem. Several new drugs, targeting the IL-23/IL-17A pathway, have been recently licensed or are in clinical development. These therapies represent a major improvement of the way in which psoriasis is managed, since they show an unprecedented efficacy on skin symptoms of psoriasis. This has been made possible, thanks to an increasingly more accurate pathogenic view of psoriasis. Today, the belief that Th17 cells mediate psoriasis is moving to the concept of psoriasis as an IL-17A-driven disease. New questions arise at the horizon, given that IL-17A is part of a newly described family of cytokines, which has five distinct homologous: IL-17B, IL-17C, IL-17D, IL-17E, also known as IL-25 and IL-17F. IL-17 family cytokines elicit similar effects in target cells, but simultaneously trigger different and sometimes opposite functions in a tissue-specific manner. This is complicated by the fact that IL-17 cytokines show a high capacity of synergisms with other inflammatory stimuli. In this review, we will summarize the current knowledge around the cytokines belonging to the IL-17 family in relation to skin inflammation in general and psoriasis in particular, and discuss possible clinical implications. A comprehensive understanding of the different roles played by the IL-17 cytokines is crucial to appreciate current and developing therapies and to allow an effective pathogenesis- and mechanisms-driven drug design.

Abstract
BACKGROUND AND OBJECT Dendritic cells (DCs) are critical for initiating the activation and differentiation of T cells in inflammatory diseases including psoriasis. Curcuma kwangsiensis S.G. Lee & C.F. Liang is a herb for treating psoriasis and we previously found Diarylheptanoid from rhizomes of Curcuma kwangsiensis (DCK) inhibited keratinocytes proliferation. However, it is unknown whether DCK influences DC functions. Thus we aimed to explore whether DCK affect the major immunological functions of DCs. MATERIALS AND METHODS Primary DCs derived from mouse bone marrow cells and spleen were used for examining their general immunological functions, and OVA-specific T cells from OT-II mice were used for examining the DC-mediated T-helper (Th) 1 and Th17 cells differentiation and effect. RESULTS We demonstrated DCK suppressed DC uptake of FITC-labeled ovalbumin (OVA) and DC maturation characterized by decreased MHCII, CD80 and CD86 following imiquimod (IMQ) stimulation. DCK also reduced DC expression of the lymphoid-homing chemokine receptor CCR7, and DC migration towards CCL21, the ligand for CCR7. Importantly, DCK significantly reduced the production of proinflammatory cytokines including IL-12, IL-6 and IL-1β by IMQ-stimulated DCs. Moreover, in the coculture of OVA323-339 peptide-pulsed DCs and OVA-specific T cells from OT-II mice, DCK significantly inhibited T cell proliferation and the differentiation of Th1 and Th17 cells. Furthermore, DCK treatment greatly reduced phosphorylation of p65-associated cell signaling pathway in IMQ-stimulated DCs. CONCLUSION These data together demonstrate a potential role of DCK in suppressing the biological function of DCs, and provide a possible mechanism for understanding the effects of herb Curcuma kwangsiensis in treating psoriasis.

Abstract
Infection or sterile inflammation triggers site-specific attraction of leukocytes. Leukocyte recruitment is a process comprising several steps orchestrated by adhesion molecules, chemokines, cytokines and endogenous regulatory molecules. Distinct adhesive interactions between endothelial cells and leukocytes and signaling mechanisms contribute to the temporal and spatial fine-tuning of the leukocyte adhesion cascade. Central players in the leukocyte adhesion cascade include the leukocyte adhesion receptors of the β2-integrin family, such as the αLβ2 and αMβ2 integrins, or of the β1-integrin family, such as the α4β1-integrin. Given the central involvement of leukocyte recruitment in different inflammatory and autoimmune diseases, the leukocyte adhesion cascade in general, and leukocyte integrins in particular, represent key therapeutic targets. In this context, the present review focuses on the role of leukocyte integrins in the leukocyte adhesion cascade. Experimental evidence that has implicated leukocyte integrins as targets in animal models of inflammatory disorders, such as experimental autoimmune encephalomyelitis, psoriasis, inflammatory bone loss and inflammatory bowel disease as well as preclinical and clinical therapeutic applications of antibodies that target leukocyte integrins in various inflammatory disorders are presented. Finally, we review recent findings on endogenous inhibitors that modify leukocyte integrin function, which could emerge as promising therapeutic targets.

Abstract
Psoriasis is an autoimmune disease, which symptoms can significantly impair the patient's life quality. It is mainly diagnosed through the visual inspection of the lesion skin by experienced dermatologists. Currently no cure for psoriasis is available due to limited knowledge about its pathogenesis and development mechanisms. Previous studies have profiled hundreds of differentially expressed genes related to psoriasis, however with no robust psoriasis prediction model available. This study integrated the knowledge of three feature selection algorithms that revealed 21 features belonging to 18 genes as candidate markers. The final psoriasis classification model was established using the novel Incremental Feature Selection algorithm that utilizes only 3 features from 2 unique genes, IGFL1 and C10orf99. This model has demonstrated highly stable prediction accuracy (averaged at 99.81%) over three independent validation strategies. The two marker genes, IGFL1 and C10orf99, were revealed as the upstream components of growth signal transduction pathway of psoriatic pathogenesis.

Abstract
Cutaneous microdialysis demonstrates cytokine production in living human skin. In the present study, microdialysis samples taken from uninvolved and lesional skin in three test subjects with psoriasis over 24 h have been investigated for cytokine content with a bead-based multiplex immunoassay from Luminex. Concentration curves for a set of Th1/Th2 and pro-inflammatory cytokines measured differed from a reference group of ten subjects without psoriasis. The time to return to near baseline values after innate insertion reactivity is between 9 and 16 h. Post-equilibration levels (17-24 h) for the three main cytokines elevated in the reference group were differentially elevated outside the range of the reference group for interleukin-1β (IL1β) and IL8 but not so for IL6. Two further cytokines, granulocyte-macrophage colony-stimulating factor and tumor necrosis factor-α not generally elevated in the reference group, showed elevated values in the test subjects. Multivariate time series analysis (chemometry) showed that cytokine patterns for the individual test subjects often fell outside the 99% confidence intervals of a model generated from the reference group. In a clinical research situation, cutaneous microdialysis is feasible, gives generally higher cytokine levels than in the blood and generates interpretable data on an individual's reactivity compared with a reference group. This may well prove useful in delineation of pathogenetic issues, selection of appropriate therapy and monitoring of subsequent response in inflammatory dermatoses such as psoriasis.

Abstract
Psoriasis is a chronic inflammatory and immune-mediated disease associated with several comorbidities, such as obesity, hypertension, diabetes mellitus, dyslipidemia and cardiovascular disorder. These comorbidities are components of metabolic syndrome. The pathogenesis of metabolic syndrome is supposed to be related to increased levels of adipocytokines, such as tumor necrosis factor-α (TNF-α) and adiponectin. Recent study has revealed a high prevalence of metabolic syndrome in psoriatics compared with other skin diseases. Biologic agents, including anti-TNF-α antibodies, are recommended as the first-line treatment for psoriatics with metabolic syndrome. This article reviews the association of psoriasis and metabolic syndrome in terms of adipocytokines and evaluates the role of biologic agents in the treatment of psoriasis.

Abstract
Psoriasis is chronic autoimmune hyperproliferative skin disease with a population prevalence of 1.5-3%. The cause of psoriasis is still not fully understood. It has been hypothesized to be an immune-mediated disorder in which the excessive reproduction of keratinocytes is due to cytokines such as interferon (IFN)-gamma and tumour necrosis factor (TNF)-alpha, secreted by infiltrating CD4(+) and CD8(+) T cells and natural killer cells. The aim of our study was to determine the serum levels of TNF-α, IL-4, IL-6 & IL-10 in psoriasis patients and compare it with healthy controls. 30 clinically diagnosed psoriasis patients and 30 age and sex matched healthy controls were included in the study. The serum cytokine levels were measured by solid phase sandwich ELISA (DIACLONE Research, France). TNF-α and IL-6 levels were significantly raised in patients and the results were statistically significant (P < 0.001). IL-4 levels were higher in patients than in controls (1.91 ± 4.7 pg/ml in cases & 0.9 ± 0.3 pg/ml in controls) but were not statistically significant. Interestingly, IL-10 levels were found to be higher in controls than in patients but again, it was not statistically significant. Pro-inflammatory cytokines play a pivotal role in the pathogenesis of psoriasis and it is the type 1(TH1) cytokine pattern, i.e., IL-6 & TNF-α, which predominate in the psoriatic T cell response. Further studies on IL-10 levels in psoriasis are recommended to establish their exact role in the pathogenesis of the disease.

Abstract
The traffic of the different types of immune cells is an important aspect in the immune response. Chemokines are soluble peptides that are able to attract cells by interaction with chemokine receptors on their target cells. Several different chemokines and receptors exist enabling the specific trafficking of different immune cells. In chronic inflammatory disorders there is abundance of immune cells present at the inflammatory site. This review focuses on the role of chemokine receptors in chronic inflammatory disorders of the lungs, intestine, joints, skin and nervous system and the potential of targeting these receptors as therapeutic intervention in these disorders.

Abstract
Psoriasis affects 2.7% of the world's population. The sequence of these events remains controversial. Because antigen presenting is necessary for T-cell activation, dendritic cells may be involved in the pathogenesis of psoriasis. To investigate their role, we examined immunophenotyping of different dendritic cells and their distribution and numbers in psoriasis patients. Immunohistochemistry of CD1a, CD11c, CD86 and BDCA2 were performed using paraffin-embedded tissue obtained from a total of 45 patients with psoriasis. Samples were taken from the lesion, perilesional and distant skin and normal skin obtained from 10 control cases. There were marked increase in the number of positive CD1a, CD11c, CD86 and BDCA2 cells in perilesional and the psoriatic skin when compared to the distant skin and they were the least in the normal control skin. So different dendritic cells subsets have a very important role in psoriasis pathogenesis especially in initiation of the plaque in the perilesional skin.

Abstract
Psoriasis is a multifactorial skin dermatosis characterized in its classical form by erythematous and hyperkeratotic plaques on extensor surfaces of the body, that in most cases can be managed therapeutically by topical agents. Hyperproliferation and a marked inflammation in both epidermis and dermis are thought to be driven by interaction of activated type-1 T lymphocytes and antigen-presenting cells and keratinocytes that release several proinflammatory and immunomodulating molecules. The aim of this study is to investigate whether tetrabromofluorecin, commonly know as eosin, a classical compound traditionally topically used in psoriasis for its presumed anti-inflammatory activities, is able to modulate the production of TNF-alpha, IL-6 and IL-8 that are recognized as the most active and characterized cytokines in the pathogenesis of this skin disorder. HaCaT cell line was used to verify the effects on epidermal inflammation by eosin at scalar doses after testing the viability of cells. Two different population of cells, one stimulated by IFNgamma and one non-stimulated, were cultivated in presence of tolerable concentrations. The expression and release of IL-6, IL-8, IL-10, and TNF-alpha were analysed by RT-PCR and ELISA, respectively. Our results show that tolerable concentrations of eosin were 0.05%, 0.02%, and 0.01%. The expression and production of TNFalpha, IL-8 and IL-6 were dramatically reduced in presence of eosin 0.05% and 0.02% and the action of eosin was more pronounced on TNF-alpha. In agreement with clinical data, our results show that in presence of tolerable concentrations, eosin seems to influence remarkably the production of three important cytokines involved in the hyperproliferation and inflammatory process, giving a specific explanation of its efficacy and supporting its topical use in the clinical setting.

Abstract
BACKGROUND Congaplex and Immuplex are dietary supplements that have been traditionally used to support immune system function. The purpose of these experiments was to determine whether Congaplex and Immuplex affect immune function using primary and immortalized T lymphocytes. METHODS Immortalized CEM and Jurkat T lymphocytes and primary peripheral mononuclear blood cells (PBMCs) were treated with the aqueous extracts from Congaplex and Immuplex to determine the effects of these products on cytokine production in activated T lymphocytes. RESULTS Congaplex enhanced phytohemagglutinin/phorbol 12-myristate 13-acetate (PHA/PMA) stimulation of both CEM and Jurkat cells as measured by the production of cytokines, while Immuplex suppressed PHA/PMA-induced production of cytokines, with the exception of interleukin (IL)-8 which was enhanced by Immuplex. In vitro treatment of PBMCs from 10 healthy donors with Congaplex or Immuplex decreased PHA-stimulated production of interferon (IFN)-gamma but increased the production of IL-13. CONCLUSIONS While the effects of Congaplex and Immuplex differed in these two models, these data demonstrate that the aqueous extracts from these two dietary supplements can affect the inflammatory response of T lymphocytes.

Abstract
Psoriasis is an immune-mediated disease which affects a large world population. It has long been considered a dermatological disorder in which keratinocytes and lymphocytes play a relevant pathogenic role. The aim of our study is to more closely observe and better define the role of dendritic cells (DCs) in psoriasis. We made a comparative analysis of the antigenic profile and the number, by immunohistochemical and electron microscopical study, of skin biopsy samples from psoriatic patients before and 4 months after biological treatments. Our results demonstrate an abundant distribution of activated DCs in lesional skin of psoriatic plaques and a marked decrease after biological therapies [a decrease of 70% for Langerhans cells (LCs) and mature myeloid dendritic cells (mDCs) and of 50% for plasmocytoid dendritic cells (pDCs)]. Both previous reports and the results of the present study support an underlying persistent immune response involving DCs in the onset and persistence of psoriasis. As DCs play a pivotal role in pathogenesis of psoriasis by presenting antigens via major histocompatibility complex class (MHC) II molecules, the present study supports the view that biological therapies are also effective in clearing psoriatic lesions as well as in reducing the number of DCs.

Abstract
Background Psoriasis is an immune-mediated disease characterized by aberrant epidermal differentiation, surface scale formation, and marked cutaneous inflammation. To better understand the pathogenesis of this disease and identify potential mediators, we used whole genome array analysis to profile paired lesional and nonlesional psoriatic skin and skin from healthy donors. Methodology/Principal Findings We observed robust overexpression of type I interferon (IFN)–inducible genes and genomic signatures that indicate T cell and dendritic cell infiltration in lesional skin. Up-regulation of mRNAs for IFN-α subtypes was observed in lesional skin compared with nonlesional skin. Enrichment of mature dendritic cells and 2 type I IFN–inducible proteins, STAT1 and ISG15, were observed in the majority of lesional skin biopsies. Concordant overexpression of IFN-γ and TNF-α–inducible gene signatures occurred at the same disease sites. Conclusions/Significance Up-regulation of TNF-α and elevation of the TNF-α–inducible gene signature in lesional skin underscore the importance of this cytokine in psoriasis; these data describe a molecular basis for the therapeutic activity of anti–TNF-α agents. Furthermore, these findings implicate type I IFNs in the pathogenesis of psoriasis. Consistent and significant up-regulation of type I IFNs and their associated gene signatures in psoriatic skin suggest that type I IFNs may be potential therapeutic targets in psoriasis treatment.

Abstract
S100A8 and S100A9 are known to be up-regulated in hyperproliferative and psoriatic epidermis, but their function in epidermal keratinocytes remains largely unknown. Here we show that (1) S100A8 and S100A9 are secreted by cultured normal human keratinocytes (NHK) in a cytokine-dependent manner, (2) when applied to NHK, recombinant S100A8/A9 (a 1:1 mixture of S100A8 and S100A9) induced expression of a number of cytokine genes such as IL-8/CXCL8, CXCL1, CXCL2, CXCL3, CCL20, IL-6, and TNFalpha that are known to be up-regulated in psoriatic epidermis, (3) the S100A8/A9-induced cytokines in turn enhanced production and secretion of S100A8 and S100A9 by NHK, and (4) S100A8 and S100A8/A9 stimulated the growth of NHK at a concentration as low as 1 ng/ml. These results indicate the presence of a positive feedback loop for growth stimulation involving S100A8/A9 and cytokines in human epidermal keratinocytes, implicating the relevance of the positive feedback loop to the etiology of hyperproliferative skin diseases, including psoriasis.

Abstract
This study was performed to investigate the association between interferon (IFN)-gamma single nucleotide polymorphism (SNP) and susceptibility for psoriasis vulgaris. DNA from 78 patients with psoriasis vulgaris (54 patients with type I psoriasis, 24 with type II psoriasis) and 74 healthy volunteers was investigated. IFN-gamma promoter gene SNP in position 874 was evaluated by polymerase chain reaction with sequence-specific primers (PCR-SSP) and the results were compared between a group of psoriatic patients, divided into early onset of psoriasis (type I) and late onset of psoriasis (type II) subgroups, and healthy control subjects. A significant difference in the genotype frequencies between psoriasis patients and healthy controls was found (p < 0.02) and no significant differences were observed analyzing subsets of psoriatic patients (gender, type of disease) also in carriage and allele frequencies. The results suggest that IFN-gamma polymorphism is associated with susceptibility to psoriasis vulgaris.

Abstract
The multifunctional cytokine tumor necrosis factor-alpha (TNF-alpha) is known to play an important role in inflammatory and immunological responses in human skin. Although it has been documented that reactive oxygen species (ROS) are involved in TNF-alpha-induced signaling pathways associated with certain inflammatory diseases, their role in TNF-alpha signaling cascades has not been examined in primary human keratinocytes used as a model of inflammatory skin disease and psoriasis. Employing a series of in vitro and in cellulo approaches, we have demonstrated that in primary human keratinocytes (i) TNF-alpha rapidly induces ROS generation, IkappaB degradation, NF-kappaB p65 nuclear translocation, and ultimately production of inflammatory cytokines; (ii) TNF-alpha-induced cytokine production is mediated both by the mammalian target of rapamycin signaling pathway via NF-kappaB activation and by ROS; (iii) TNF-alpha-dependent NF-kappaB activation (that is, IkappaB degradation and NF-kappaB p65 nuclear translocation) is not mediated by ROS; and (iv) a cell-penetrating derivative of the antioxidant enzyme, catalase, as well as taurine and N-acetyl-cysteine attenuate the TNF-alpha-induced production of cytokines. These latter results suggest that catalase and perhaps other antioxidants should be considered as part of a more specific and effective therapy for the treatment of inflammatory skin diseases, including psoriasis.

Abstract
PURPOSE Calcipotriol is a potent drug for topical treatment of psoriasis because it manages to inhibit keratinocyte proliferation. In the present study we investigated the effects of calcipotriol on gene expression in human keratinocytes in terms of mechanism of how calcipotriol decreases proliferation. MATERIALS AND METHODS Cell proliferation was analyzed by MTT assay. The differential display approach together with qPCR was used to assess the gene expression after treatment. In addition, Western immunoblotting revealed differences on the protein level. Finally, transfection of the KCs with specific small interfering RNA determined the genes necessary to inhibit proliferation. RESULTS KCs proliferation was decreased in a concentration-dependent manner. Moreover, calcipotriol dowregulated the expression of two proliferation factors: early growth response-1 (EGR1) and polo-like kinase-2 (PLK2). The protein levels of EGR1 and PLK2 were also decreased. Specific siRNA against EGR1 and PLK2 in KCs resulted in marked reduction of EGR1 and PLK2 expression. In both cases, the reduction resolved in the decreased proliferation of KCs. CONCLUSION This study provides a new insight into how calcipotriol affects proliferation of keratinocytes by decreasing the expression of EGR1 and PLK2. Furthermore, the results offer groundwork for developing novel compounds for the treatment of hyperproliferative skin disorders like psoriasis.

Abstract
BACKGROUND Previous reports have shown an association between inflammatory diseases such as systemic lupus erythematosus or rheumatoid arthritis and the metabolic syndrome. Recent data demonstrate that psoriasis is an inflammatory disease, suggesting that psoriasis may be one of the components of the metabolic syndrome. OBJECTIVE To assess the association between psoriasis and the metabolic syndrome. METHODS A cross-sectional study was performed utilizing the database of the Clalit Health Services. Case patients were defined as patients with a diagnosis of psoriasis vulgaris. Controls were randomly selected from the list of Clalit Health Services enrollees. The proportions of components of the metabolic syndrome (ischemic heart disease, hypertension, diabetes, obesity and dyslipidemia) were compared between case and control patients by univariate analyses. chi(2) tests were used to compare categorical parameters between the groups. Logistic and linear regression models served to measure the association between psoriasis and the metabolic syndrome. RESULTS The study included 16,851 patients with psoriasis and 48,681 controls. In the case group, there were 8,449 men (50.1%) and 8,402 women (49.9%), with a mean age of 42.7 years (SD = 20.3, range = 2-111). Diabetes mellitus was present in 13.8% of the patients with psoriasis as compared to 7.3% of the controls (p < 0.001). Hypertension occurred in 27.5% of the patients with psoriasis and in 14.4% of the controls (p < 0.001). Obesity was present in 8.4% of the patients with psoriasis as opposed to 3.6% of the controls (p < 0.001). Ischemic heart disease was observed in 14.2% of the patients with psoriasis as compared to 7.1% of the controls (p < 0.001). Multivariate models adjusting for age, gender and smoking status of the patients demonstrated that psoriasis was associated with the metabolic syndrome (OR = 1.3, 95% CI = 1.1-1.4), ischemic heart disease (OR = 1.1, 95% CI = 1.0-1.2), diabetes mellitus (OR = 1.2, 95% CI = 1.0-1.3), hypertension (OR = 1.3, 95% CI = 1.2-1.5) and obesity (OR = 1.7, 95% CI = 1.5-1.9). LIMITATIONS The study is designed as a case-control study, thus an association alone was proven and not causality. CONCLUSION Our findings demonstrate a possible association between psoriasis and the metabolic syndrome. Appropriate treatment of the metabolic syndrome may be an important part of the management of patients with psoriasis.

Abstract
The presence and severity of skin and joint symptoms in patients with psoriasis and psoriatic arthritis frequently do not correspond, a discrepancy that has raised the question of whether they represent two related but different disease processes. The fact that some agents seem to work preferentially in one state over the other reinforces this idea. However, there are also several agents with combined efficacy against cutaneous and articular inflammation that appear to support the existence of a common aetiology. Here we review the clinical, epidemiological and genetic evidence for and against a common pathogenesis for the two diseases. We then discuss the cellular and molecular targets of their selected therapies and how they potentially implicate effector pathways as a common immunopathogenic mechanism. Finally, we examine a recently proposed model of psoriasis pathogenesis involving type 1 interferon-producing plasmacytoid dendritic cells and how it may provide further clues to the aetiological links between psoriasis and psoriatic arthritis.

Abstract
Natural health products (NHPs) or complementary and alternative medicine (CAM) are commonly used to prevent disorders or support the usual treatments of many diseases. XP-828L, a whey protein extract, has demonstrated potential benefits for the treatment of mild to moderate psoriasis. The aim of this study was to analyze further clinical data that demonstrated the clinical benefits and safety of the XP-828L in patients with psoriasis and the potential mechanism of action of this product in vitro. Oral administration (2.5 g, twice a day, over 112 days) of XP-828L in 42 human subjects with mild to moderate psoriasis improved their PGA scores (physician’s global assessment). Moreover, no significant changes in haematology or hepatic and renal parameters were observed throughout the study period, indicating the safety of the product. In vitro experiments showed that XP-828L decreased the proliferation of concanavalin A (ConA)-stimulated murine splenocytes and their production of interleukin (IL)-2 and interferon (IFN)-γ. Although the in vivo mechanism of action of XP-828L remains unknown, XP-828L represents an NHP to be used as an alternative or concomitant treatment for mild to moderate psoriasis and potentially for other immune-mediated diseases.

Abstract
Psoriasis vulgaris is a chronic inflammatory skin disease that is marked by a complex interplay of dendritic cells (DCs), T-cells, cytokines, and downstream transcription factors as part of a self-sustaining type 1 cytokine network. As integral players of the immune system, DCs represent antigen-presenting cells that are crucial for efficient activation of T-cells and B-cells. DCs have also been linked to distinct chronic inflammatory conditions, including psoriasis. In the setting of psoriasis therapy, DC/T cell interactions serve as a potential target for biologic response modifiers. Here we describe the major DC subsets as well as the immunologic involvement of DCs within the context of psoriatic lesions.

Abstract
Early inflammatory changes in psoriatic plaques were investigated immunohistochemically by studying the normal-appearing skin adjacent to the plaques (perilesional skin), lesional skin, and distant uninvolved skin from psoriasis patients. Perilesional epidermis contained numerous CD1a-positive Langerhans cells, some of which expressed HLA-DR, CD83, CD80, and CD86, at the same time expressing Langerin. There were also numerous CD83-positive, CD11c-positive, Langerin-negative dendritic cells (DCs) in the epidermal-dermal junction of perilesional skin. CD3-positive T lymphocytes were sparse in the perilesional skin. Perilesional epidermis expressed keratin K6 and K16, inflammatory keratins, and C/EBPbeta, a transcription factor related to inflammatory cytokines. Our results demonstrated the abundant distribution of activated DCs in the perilesional skin of psoriatic plaques, where early inflammatory changes occur in the epidermal keratinocytes, which suggests their involvement in the provocation of epidermal inflammation in the perilesional epidermis and further pathogenic roles in the formation of psoriatic plaques.

Abstract
Presented herein are 18 cases of erythematous, scaly papules or plaques with microscopic features of both seborrheic keratosis and psoriasis. There was, however, no known clinical diagnosis of psoriasis in any patient, neither at initial presentation nor on follow-up examination. Most lesions were solitary, present for 6-7 months, and identified on the upper or lower extremities. Other sites included the scalp, neck, shoulders, and back. Men were affected slightly more often than women. The mean age at diagnosis was 66.8 years. The most common diagnoses, clinically, were seborrheic keratosis, followed by basal cell carcinoma, Bowen's disease, actinic (solar) keratosis, and squamous cell carcinoma, among others. The lesions averaged less than a centimeter in diameter and were dome shaped, scaly, and yellow to gray-tan. Histologic examination revealed irregular verrucous epidermal acanthosis, with hyperkeratosis, parakeratosis, hypergranulosis, and intracorneal collections of neutrophils, often in alternating tiers. Vascular dilatation and lymphocytic chronic inflammation were present in the superficial dermis. Periodic acid-Schiff (PAS) stain for yeasts or dermatophytes was negative in all cases. There was no clinical evidence of disseminated psoriasis in any patient; the mean follow-up duration was 22.6 months. We have coined the term psoriasiform keratosis as a provisional appellation until the nature of these lesions is determined more definitively. It is unclear whether a psoriasiform keratosis is a rudimentary manifestation of psoriasis or a lesion sui generis.

Abstract
T cells regulate the disease process in rheumatoid arthritis (RA) on multiple levels and represent a logical choice for anti-inflammatory therapy. In the inflamed joint they promote neoangiogenesis and lymphoid organogenesis, and stimulate synoviocyte proliferation and development of bone-eroding osteoclasts. The design of T-cell-targeted therapies for RA needs to take into account the uniqueness of T-cell generation, turnover and differentiation in affected patients. Patients accumulate 'old' T cells that respond to alternate regulatory signals because of an accelerated immune aging process; any therapeutic interventions that increase the replicative stress of T cells should, therefore, be avoided. Instead, therapeutic approaches that raise the threshold for T-cell activation are more promising. As a rule, antigen-derived signals synergize with co-stimulatory signals to stimulate T cells; such co-stimulatory signals are now targeted in novel immunosuppressive therapies. An example is abatacept (soluble cytotoxic-T-lymphocyte-associated protein 4-immunoglobulin), which binds with high affinity to CD80/CD86 and effectively suppresses inflammatory activity in RA. The therapeutic benefits gained by disrupting T-cell co-stimulation indicate that the pathogenesis of RA is driven by a more generalized abnormality in T-cell activation thresholds rather than a highly selective action of arthritogenic antigens.

Abstract
Psoriasis is a chronic immune-mediated inflammatory skin disease characterised by abnormal keratinocyte differentiation and proliferation. The immunopathogenesis is complex and novel evidence shows the involvement of both innate and adaptive immune response. Type 1 T cells and their effector cytokines play a pivotal role. Several drugs under preclinical and clinical development for psoriasis are directed against the immune response, targeting activation or proliferation of T cells, their trafficking and skin-homing, or effector cytokines. Among these, great attention has been given to TNF-alpha, following the demonstration of effectiveness of anti-TNF-alpha biologicals, and to IFN-gamma inducers. Another appealing approach concerns drugs capable of inducing immunological tolerance. Progress made in the recognition of intracellular events has prompted the development of small molecules and oligonucleotides that can inhibit specific molecular targets. There is, however, a plethora of other emerging drugs, clearly suggestive of the current interest for psoriasis, which are briefly described in this paper.

Abstract
Psoriasis is a chronic skin disorder affecting approximately 1% to 3% of the world's population. A considerable proportion of patients with psoriasis will develop a form of inflammatory arthritis known as psoriatic arthritis whose prevalence is poorly defined. Significant advances have been made in determining the pathophysiology of both of these diseases, with recent findings strongly implicating T cells and inflammatory cytokines such as tumor necrosis factor alpha in their pathogenesis. There exists an increasing array of therapies to benefit both skin and musculoskeletal manifestations. Newer therapies, such as the biologics, are providing more targeted approaches with potentially fewer systemic toxicities, providing control of disease symptoms and inhibiting progressive joint damage in those with arthritis, as well as improving long-term function and quality of life.

[PMID: 16359823 DOI: 10.1016/j.psyneuen.2005.10.006] [Citation(s) in RCA: 61] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/15/2005] [Revised: 10/17/2005] [Accepted: 10/21/2005] [Indexed: 11/30/2022]
Abstract
In previous research we reported attenuated responsiveness of the hypothalamus-pituitary-adrenal (HPA) axis and further, an increased reactivity of the sympathetic adrenomedullary (SAM) system to stress in patients suffering from atopic dermatitis (AD). AD is a chronic inflammatory skin disease mainly triggered by TH(2)-dependent inflammatory processes. The specific goal of the present study was to investigate whether altered HPA axis and SAM system responsiveness to stress can also be found in TH(1)-mediated inflammatory conditions. Patients with psoriasis (PSO; n=23), a TH(1)-mediated inflammatory (autoimmune) skin disease and healthy controls (n=25) were exposed to a standardized laboratory stressor (TSST) which mainly consists of a free speech and a mental arithmetic task in front of an audience. To investigate HPA axis and SAM system responsiveness, cortisol, ACTH, and catecholamines were determined before and after the stress test. In addition, cortisol levels after awakening and cortisol levels during the day (short diurnal profile) were determined. In order to test feedback sensitivity of the HPA axis, a dexamethasone (DEX) suppression test (0.5 mg) was performed. Analysis of cortisol and ACTH levels after the stress test yielded no significant differences between PSO subjects and controls indicating no altered HPA axis function in this patient group. Further, no between-group differences were found in cortisol levels after awakening or during the day (short diurnal profile). Additionally, no difference between PSO and healthy subjects in the feedback sensitivity of the system could be found (DEX test). However, PSO patients showed elevated epinephrine (F(3,102)=4.7; p<0.005) and norepinephrine (F(3,135)=2.7; p<0.05) levels in response to the stress test when compared to the controls. These findings suggest no altered HPA axis responsiveness, but increased reactivity of the SAM system in TH(1)-mediated chronic inflammatory skin disease.

Abstract
Recent progress in the understanding of psoriasis
has shown that the regulation of local and systemic cytokines
plays an important role in its pathogenesis. The most
often used psoriasis score is the psoriasis area and severity
index (PASI). A simple laboratory test from a blood sample would
be an attractive, patient-independent, and observer-independent
marker of disease severity. To this end, we evaluated the
association of serum levels of some proinflammatory cytokines
in vivo and their correlation with severity of psoriasis.
The serum levels of cytokines levels were determined with the use
of the ELISA method. All mean values except IL-17 levels of
patients were significantly higher than those of controls. There
was a significant correlation between serum levels of IFN-γ,
IL-12, IL-17, and IL-18, and severity of the disease. Psoriasis
can be described as a T-cell-mediated disease, with a
complex role for a variety of cytokines, which has led to
the development of new immunomodulatory therapies. In this study,
serum TNF-α, IFN-γ, IL-6, IL-8, IL-12, and IL-18
levels were significantly higher in active psoriatic patients than
in controls. Furthermore, high levels of IFN-γ, IL-12, and
IL-18 correlated with the clinical severity and activity of
psoriasis, and those measurements of serum levels of these
cytokines may be objective parameters for the disease severity.

Abstract
We have examined whether psoriasis is associated with systemic effects on epidermal Langerhans cell (LC) function and, specifically, the migration of LCs from the skin. Compared with normal skin, the frequency and morphology of epidermal LCs in uninvolved skin from patients with psoriasis was normal. However, mobilization of these cells in response to stimuli that normally induce migration (chemical allergen, tumor necrosis factor α [TNF-α], and interleukin-1β [IL-1β]) was largely absent, despite the fact that treatment with TNF-α and IL-1β was associated with comparable inflammatory reactions in patients and controls. The failure of LC migration from uninvolved skin was not attributable to altered expression of receptors for IL-1β or TNF-α that are required for mobilization, nor was there an association with induced cutaneous cytokine expression. Although a role for altered dynamics of LC migration/turnover has not been formally excluded, these data reveal a very consistent decrement of LC function in psoriasis that may play a decisive role in disease pathogenesis.

Abstract
The role of human papillomaviruses (HPVs) in the pathogenesis of psoriasis is uncertain, and it has been postulated that the virus can act as a putative superantigen or it is activated from a latent status by inflammatory cytokines. To determine the involvement of HPV in the pathogenesis of psoriasis, primary cultures of keratinocytes from psoriatic lesions were analysed for the viral presence and for the production of inflammatory cytokines. Biopsies were taken from psoriatic lesions of 11 patients and from healthy donors undergoing plastic surgery. HPV DNA/RNAs were detected by nested polymerase chain reaction methods. The secretion of interleukin-6 (IL-6), IL-8 and IL-18 was determined in the conditioned medium by commercial enzyme-linked immunosorbent assay kits. Sixty-four per cent of the psoriatic keratinocytes were positive to HPV type 5 (HPV5), whereas no normal samples showed the presence of viral sequences. In the corresponding paraffin-embedded sections, multiple infection by HPV5 and HPV1 was detected. Comparable results in the production of inflammatory cytokines were obtained from HPV-infected vs. non-infected cell cultures. Specific HPV5 mRNAs were detected in the keratinocytes in the absence of cytokine stimulation, indicating that the expression of the viral genome may not be a consequence of the activation of the viral promoter by cytokines. The results are suggestive of an involvement of HPV5 in the psoriasis and reinforce the hypothesis that the replication of this virus in the psoriatic keratinocytes may cause the epidermal hyperproliferation as well as the antigen stimulation, which induces autoimmune phenomena.

Abstract
BACKGROUND The pathophysiology of psoriasis is poorly understood, and the mechanism of action of biological agents interfering with tumour necrosis factor (TNF)-alpha that improve psoriatic plaques is completely unknown. OBJECTIVES To begin to unravel the mechanism of action, cellular changes occurring in plaques following administration of adalimumab, a humanized monoclonal antibody against TNF-alpha, were investigated. METHODS Thirteen different patients underwent sequential biopsies as part of a clinical trial. Each biopsy was immunostained and evaluated to calculate the relative density of epidermal Langerhans cells (LCs) before and after treatment (days 2, 7, 28, 84). To explore the basis for reduced epidermal LC densities in plaques, a SCID-Hu animal model was utilized. Acute psoriatic lesions were created within 2 weeks by injection of superantigen-activated CD4+ T cells into engrafted symptomless skin. RESULTS Compared with symptomless skin, untreated plaques had a significantly reduced density of epidermal LCs. There was a rapid increase in density of epidermal LCs in plaques following treatment with adalimumab beginning as early as day 7. The paucity of epidermal LCs in plaques was contrasted to the prominent density of LCs in other skin disorders with chronic inflammation and alterations in keratinization, including lichen planus and inflamed seborrhoeic keratosis. Rapid creation of plaques using the SCID-Hu model was accompanied by loss of epidermal LCs, indicating that diminished LC density occurs at an early stage of lesion formation. CONCLUSIONS These data shed light on a new immunopathological perspective highlighting a rapid loss of epidermal LCs in acute psoriatic lesions, with sustained decreased density of LCs in chronic plaques. Furthermore, an unexpected insight into the mechanism of action was uncovered for adalimumab, in which rapid restoration of epidermal LC density was observed.
