J Pharm Biomed Anal 2024; 245:116163. [PMID: 38657365 DOI: 10.1016/j.jpba.2024.116163] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2024] [Revised: 04/17/2024] [Accepted: 04/17/2024] [Indexed: 04/26/2024]
Abstract
Psoriasis is a refractory inflammatory skin disorder in which keratinocyte hyperproliferation is a crucial pathogenic factor. Up to now, it is commonly acknowledged that psoriasis has a tight connection with metabolic disorders. Withanolides from Datura metel L. (DML) have been proved to possess anti-inflammatory and anti-proliferative properties in multiple diseases including psoriasis. Withanolide B (WB) is one of the abundant molecular components in DML. However, existing experimental studies regarding the potential effects and mechanisms of WB on psoriasis still remain lacking. Present study aimed to integrate network pharmacology and untargeted metabolomics strategies to investigate the therapeutic effects and mechanisms of WB on metabolic disorders in psoriasis. In our study, we observed that WB might effectively improve the symptoms of psoriasis and alleviate the epidermal hyperplasia in imiquimod (IMQ)-induced psoriasis-like mice. Both network pharmacology and untargeted metabolomics results suggested that arachidonic acid metabolism and arginine and proline metabolism pathways were linked to the treatment of psoriasis with WB. Meanwhile, we also found that WB may affect the expression of regulated enzymes 5-lipoxygenase (5-LOX), 12-LOX, ornithine decarboxylase 1 (ODC1) and arginase 1 (ARG1) in the arachidonic acid metabolism and arginine and proline metabolism pathways. In summary, this paper showed the potential metabolic mechanisms of WB against psoriasis and suggested that WB would have greater potential in psoriasis treatment.

Anal Chim Acta 2023; 1252:341028. [PMID: 36935144 DOI: 10.1016/j.aca.2023.341028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2023] [Revised: 02/16/2023] [Accepted: 02/26/2023] [Indexed: 03/03/2023]
Abstract
A facile and rapid skin metabolomics protocol is proposed. The liquid microjunction-surface sampling probe system has been partly automated, and used in conjunction with hydrogel probes for skin metabolite analysis. A control device was built to precisely control the segmented solvent flow and analyte re-extraction into the liquid microjunction. This mode provides rapid online re-extraction of the analytes from hydrogel probes. Humectant was added to the hydrogel, and moist heat treatment was used to make the hydrogel probes rugged for sampling in the clinical setting. The developed method was validated for the analysis of choline - a putative biomarker of psoriasis. A linear relationship over six calibration levels from 3.18 × 10-5 to 3.18 × 10-4 mol m-2 has been obtained. The limit of detection was 6.6 × 10-6 mol m-2, while the recoveries range from 92 to 109%. The within-run and between-run precision were evaluated and the coefficients of variation range from 1.84 to 7.13%. Furthermore, the developed method has been used to screen patients (n = 10) and healthy participants (control group; n = 10) for psoriasis-related skin metabolites. Metabolomic profiling of the skin excretion-related signals identified potential biomarkers of psoriasis: choline, pipecolic acid, ornithine, urocanic acid, and methionine.

Combining network pharmacology, RNA-seq, and metabolomics strategies to reveal the mechanism of Cimicifugae Rhizoma - Smilax glabra Roxb herb pair for the treatment of psoriasis. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2022; 105:154384. [PMID: 35963195 DOI: 10.1016/j.phymed.2022.154384] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/31/2022] [Revised: 07/14/2022] [Accepted: 08/04/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Psoriasis is a prevalent chronic inflammatory skin condition marked by immune cell infiltration and keratinocyte abnormal proliferation. Cimicifugae Rhizoma - Smilax glabra Roxb (CS) herb pair, the main component of Shengma Detoxification Decoction, has been proven effective for the treatment of psoriasis. However, the mechanism is yet to be deciphered. PURPOSE To explore the mechanism of CS for the treatment of psoriasis. METHODS The imiquimod-induced psoriasis-like lesion mouse model was used to identify the targets and the molecular mechanisms of CS. Network pharmacology combined with RNA-seq strategy was employed to predict the targets and mechanisms of CS for psoriasis. Metabolomics approaches were used to demonstrate the complexity of CS for the treatment of psoriasis. Finally, a compound-response-enzyme-gene network was constructed based on the multi-omics results to elucidate potential connections. RESULTS The CS herb pair could significantly improve psoriatic lesions and reduce the inflammatory cell infiltration and proliferation of keratinocytes in skin lesions. Network pharmacology predicted that TNF, JNK, IL-6, and IL-1β could be potential targets. RNA-seq data revealed that CS could significantly regulate genes and signaling pathways associated with Th17 responses, such as IL-36, IL-1β, CCl2, CXCL16, keratin 14, keratin 5, and antimicrobial peptides S100A8 and S100A9 well as MAPK, mTOR, and other signaling pathways. Further experimental data validated that CS treatment remarkably reduced the expression of inflammatory cytokines and factors, such as CCL2, CCL7, IL1F6, IL-17, IL-23, IL-1β, TNF-α, and IL-6, and inhibited the phosphorylation of p38 and ERK1/2. This indicated that CS exerts its therapeutic effect by inhibiting the MAPK signaling pathways. In addition, metabolomic analyses demonstrated that CS treatment improved seven metabolic pathways, these included phenylalanine, tyrosine, pyruvate metabolism, carnitine metabolism, etc. Four key metabolites (L-Arginine, L-Phenylalanine, L-Carnitine, O-Acetylcarnitine) and nine differential genes (CMA1, PCBD2, TPSAB1, TPSB2, etc.) were identified that affected amino acid metabolism, carnitine metabolism, and other pathways contributing to the infiltration of Th17 cells in psoriatic lesions. CONCLUSION CS could alleviate IMQ-induced psoriasis-like dermatitis by reducing the expression of cytokines and chemokines mediated by the MAPK pathway, and improved amino acid and carnitine metabolism in vivo. Our study is the first to demonstrate the complex mechanism of CS for the treatment of psoriasis and provides a new paradigm to elucidate the pharmacological effects of Traditional Chinese Medicine (TCM) drugs for psoriasis from multiple perspectives.

[PMID: 35204165 PMCID: PMC8868066 DOI: 10.3390/antiox11020282] [Citation(s) in RCA: 22] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2022] [Revised: 01/26/2022] [Accepted: 01/28/2022] [Indexed: 02/04/2023] Open
Abstract
Psoriasis is a chronic, immune-mediated inflammatory dermatosis characterized by the appearance of erythematous plaques, covered by white scales, occasionally pruritogenic, and distributed mainly on the extensor areas. Oxidative stress is defined as an imbalance or a transient or chronic increase in the levels of free oxygen/nitrogen radicals, either as a result of the exaggerated elevation in their production or the decrease in their ability to be eliminated by antioxidant systems. Although the pathogenesis of psoriasis remains far from elucidated, there are studies that delineate an involvement of oxidative stress in this skin disorder. Thus, a systematic search was computed in PubMed/Medline, Web of Science and SCOPUS and, in total, 1293 potentially eligible articles exploring this research question were detected. Following the removal of duplicates and the exclusion of irrelevant manuscripts based on the screening of their titles and abstracts (n = 995), 298 original articles were selected for full-text review. Finally, after we applied the exclusion and inclusion criteria, 79 original articles were included in this systematic review. Overall, the data analyzed in this systematic review point out that oxidative stress markers are elevated in psoriasis and share an association with the duration and severity of the disease. The concentrations of these biomarkers are impacted on by anti-psoriasis therapy. In addition, the crosstalk between psoriasis and oxidative stress is influenced by several polymorphisms that arise in genes encoding markers or enzymes related to the redox balance. Although the involvement of oxidative stress in psoriasis remains undisputable, future research is needed to explore the utility of assessing circulating serum, plasma, urinary and/or skin biomarkers of oxidative stress and of studying polymorphisms in genes regulating the redox balance, as well as how can these findings be translated into the management of psoriasis, as well in understanding its pathogenesis and evolution.

Abstract
Endogenous gasotransmitters nitric oxide (NO), carbon monoxide (CO), hydrogen sulfide (H2S), and potential candidates sulfur dioxide (SO2), methane (CH4), hydrogen gas (H2), ammonia (NH3) and carbon dioxide (CO2), are generated within the human body. Endogenous and potential gasotransmitters regulate inflammation, vasodilation, and oxidation in inflammatory dermatological disorders. Endogenous and potential gasotransmitters play potential roles in psoriasis, atopic dermatitis, acne, and chronic skin ulcers. Further research should explore the function of these gases and gas donors and inhibitors in inflammatory dermatological disorders.
Background Endogenous gasotransmitters are small gaseous mediators that can be generated endogenously by mammalian organisms. The dysregulation of the gasotransmitter system is associated with numerous disorders ranging from inflammatory diseases to cancers. However, the relevance of these endogenous gasotransmitters, prodrug donors and inhibitors in inflammatory dermatological disorders has not yet been thoroughly reviewed and discussed. Aim of review This review discusses the recent progress and will provide perspectives on endogenous gasotransmitters in the context of inflammatory dermatological disorders. Key scientific concepts of review Endogenous gasotransmitters nitric oxide (NO), carbon monoxide (CO) and hydrogen sulfide (H2S) are signaling molecules that regulate several physiological and pathological processes. In addition, sulfur dioxide (SO₂), methane (CH4), hydrogen gas (H2), ammonia (NH3), and carbon dioxide (CO2) can also be generated endogenously and may take part in physiological and pathological processes. These signaling molecules regulate inflammation, vasodilation, and oxidative stress, offering therapeutic potential and attracting interest in the field of inflammatory dermatological disorders including psoriasis, atopic dermatitis, acne, rosacea, and chronic skin ulcers. The development of effective gas donors and inhibitors is a promising alternative to treat inflammatory dermatological disorders with controllable and precise delivery in the future.

Abstract
Arginase expression has been recently shown to increase in numerous disease states like neurodegeneration, inflammation, and malignancies. Although it has been found to be functionally important in various disease pathologies, little is known about its role in wound healing. Here, we look at the expression of arginase and its isoforms in chronic non-healing wounds and also study the expression of nitric oxide synthase (NOS) and oxidative stress enzymes in them. Wound tissues and blood samples were collected at the time of index presentation and follow-up from 61 chronic non-healing wound cases. The expression patterns of arginase isoenzymes, NOS, superoxide dismutases (SOD), lactic acid dehydrogenase (LDH), and catalase were examined by using enzyme-linked immunosorbent assay, immunohistochemistry, and western blot analysis at the transcript and protein level. We reported a significant decrease of serum arginase levels in chronic nonhealing wounds in the progress of wound healing. Interestingly, tissue arginase levels were found to be increased with improved wound condition at follow-up. Tissue NOS, LDH, and catalase activity were also found to be increased with the progress of healing, whereas SOD levels were downregulated. Our findings reported increased expression at the transcript level of arginase-I and arginase-II in chronic non-healing wounds for the first time. In conclusion, we observed decreased serum arginase levels in completely healed patients as compared to non-healed cases. Our study findings support the hypothesis that inhibition of the activity of arginase delays wound healing. Arginase and iNOS may also find their place in the future as possible biomarkers for wound healing.

Abstract
ABSTRACT Psoriasis is considered a systemic disease associated with metabolic abnormalities, and it is important to understand the mechanisms by which metabolism affects pathophysiological processes both holistically and systematically. Metabolites are closely related to disease phenotypes, especially in systemic diseases under multifactorial modulation. The emergence of metabolomics has provided information regarding metabolite changes in lesions and circulation and deepened our understanding of the association between metabolic reprogramming and psoriasis. Metabolomics has great potential for the development of effective biomarkers for clinical diagnosis, therapeutic monitoring, prediction of the efficacy of psoriasis management, and further discovery of new metabolism-based therapeutic targets.

Abstract
Psoriasis is a chronic inflammatory disease whose etiology is multifactorial. The contributions of cellular metabolism to psoriasis are unclear. Here, we report that interleukin-17 (IL-17) downregulated Protein Phosphatase 6 (PP6) in psoriatic keratinocytes, causing phosphorylation and activation of the transcription factor C/EBP-β and subsequent generation of arginase-1. Mice lacking Pp6 in keratinocytes were predisposed to psoriasis-like skin inflammation. Accumulation of arginase-1 in Pp6-deficient keratinocytes drove polyamine production from the urea cycle. Polyamines protected self-RNA released by psoriatic keratinocytes from degradation and facilitated the endocytosis of self-RNA by myeloid dendritic cells to promote toll-like receptor-7 (TLR7)-dependent RNA sensing and IL-6 production. An arginase inhibitor improved skin inflammation in murine and non-human primate models of psoriasis. Our findings suggest that urea cycle hyperreactivity and excessive polyamine generation in psoriatic keratinocytes promote self-RNA sensation and PP6 deregulation in keratinocytes is a pivotal event that amplifies the inflammatory circuits in psoriasis.

Abstract
Chronic venous ulcer (CVU) is a major cause of chronic wounds of lower extremities and presents a significant financial and resource burden to health care systems worldwide. Defects in the vasculature, matrix deposition, and re-epithelialization are the main histopathological changes believed to impede healing. Supplementation of the amino acid arginine that plays a crucial role in the interactions that occur during inflammation and wound healing was proven clinically to improve acute wound healing probably through enhancing activity of inducible arginase (AI) locally in the wounds. However, the possible mechanism of arginine action and the potential beneficial effects of AI/arginine in human chronic wounds remain unclear. In the present study, using biopsies, taken under local anesthesia, from adult patients (n = 12, mean age 55 years old) with CVUs in lower extremities, we investigated the correlation between AI distribution in CVUs and the histopathological changes, mainly proliferative and vascular changes. Our results show a distinct spatial distribution of AI along the ulcer in the epidermis and in the dermis with the highest level of expression being at the ulcer edge and the least expression towards the ulcer base. The AI cellular immunoreactivity, enzymatic activity, and protein levels were significantly increased towards the ulcer edge. Interestingly, a similar pattern of expression was encountered in the proliferative and the vascular changes with strong correlations between AI and the proliferative activity and vascular changes. Furthermore, AI cellular distribution was associated with increased proliferative activity, inflammation, and vascular changes. Our findings of differential expression of AI along the CVU base, edge, and nearby surrounding skin and its associations with increased proliferative activity and vascular changes provide further support to the AI implication in CVU pathogenesis. The presence of high levels of AI in the epidermis of chronic wounds may serve as a molecular marker of impaired healing and may provide future targets for therapeutic intervention.

Metabolic Pathways That Control Skin Homeostasis and Inflammation. Trends Mol Med 2020; 26:975-986.

Abstract
Keratinocytes and skin immune cells are actively metabolizing nutrients present in their microenvironment. This is particularly important in common chronic inflammatory skin diseases such as psoriasis and atopic dermatitis, characterized by hyperproliferation of keratinocytes and expansion of inflammatory cells, thus suggesting increased cell nutritional requirements. Proliferating inflammatory cells and keratinocytes express high levels of glucose transporter (GLUT)1, l-type amino acid transporter (LAT)1, and cationic amino acid transporters (CATs). Main metabolic regulators such as hypoxia-inducible factor (HIF)-1α, MYC, and mechanistic target of rapamycin (mTOR) control immune cell activation, proliferation, and cytokine release. Here, we provide an updated perspective regarding the potential role of nutrient transporters and metabolic pathways that could be common to immune cells and keratinocytes, to control psoriasis and atopic dermatitis.

Patients with psoriatic arthritis have higher levels of FeNO than those with only psoriasis, which may reflect a higher prevalence of a subclinical respiratory involvement. Clin Rheumatol 2020; 39:2981-2988. [PMID: 32240433 DOI: 10.1007/s10067-020-05050-2] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2019] [Revised: 03/12/2020] [Accepted: 03/20/2020] [Indexed: 12/13/2022]
Abstract
BACKGROUND Psoriatic arthritis (PsA) patients are often affected by numerous comorbidities. However, contrasting results have been reported with regard to the respiratory involvement in PsA patients. The aim of this study was to evaluate the presence of subclinical airway inflammation in non-smoking PsA patients compared to patients with only psoriasis using the fraction of exhaled nitric oxide (FeNO) as an indirect marker of airway inflammation. METHODS The study included 164 non-smoking psoriatic patients (Psoriasis Area of Severity Index or PASI score > 10): 82 with and 82 without PsA, who underwent FeNO tests at different flow rates (30, 50, 100, 200 mL/s). PsA patients were evaluated with Disease Activity in PSoriatic Arthritis Score (DAPSA). Both study groups were compared in terms of FeNO values and its association with the PASI score. The correlations between the variables were evaluated by means of Pearson's coefficient. RESULTS Patient with PsA had higher levels of FeNO than those with psoriasis but without arthritis (at 30 mL/s, 71.09 ± 18.40 ppb vs 66.88 ± 19.12 ppb (NS); at 50 mL/s, 36.61 ± 9.30 ppb vs 30.88 ± 9.73 ppb (p < 0.001); at 100 mL/s, 19.09 ± 4.66 ppb vs 16.63 ± 4.90 ppb (p < 0.001); and at 200 mL/s, 10.88 ± 2.53 ppb vs 9.43 ± 2.55 ppb (p < 0.001), respectively). PASI score correlated to FeNO only in psoriatic patients without arthritis. However, CASPAR index correlated with FeNO (FeNO30: r = 0.81, p < 0.001; FeNO50: r = 0.84, p < 0.001; FeNO100: r = 0.71, p < 0.001; FeNO200: r = 0.58, p < 0.001). DAPSA was also correlated with FeNO to all flows (FeNO30: r = 0.43, p < 0.001; FeNO50: r = 0.33, p < 0.001; FeNO100: r = 0.34, p < 0.001; FeNO200: r = 0.25, p < 0.001). CONCLUSIONS PsA patients seem to have more commonly subclinical airway inflammation than those with only psoriasis. Further studies are needed to replicate these findings. Key Points • Fraction of exhaled nitric oxide (FeNO) is a useful device to detect and monitor airway inflammation not only in asthma but also in systemic inflammatory diseases such as psoriatic arthritis and psoriasis. • Clinicians should be aware to check respiratory diseases in patients with psoriatic arthritis.

Abstract
Systematic understanding of the metabolite signature of diseases may lead to a closer understanding of the disease pathogenesis and ultimately to the development of novel therapies and diagnostic tools. Here we compared for the first time the full metabolomic profiles of lesional and non-lesional skin biopsies obtained from plaque psoriasis patients and skin samples of healthy controls. Significant differences in the concentration levels of 29 metabolites were identified that provide several novel insights into the metabolic pathways of psoriatic lesions. The metabolomic profile of the lesional psoriatic skin is mainly characterized by hallmarks of increased cell proliferation. As no significant differences were identified between non-lesional skin and healthy controls we conclude that local inflammatory process that drives the increased cell proliferation is the main cause of the identified metabolomic shifts.

Abstract
Psoriasis is a chronic hyperproliferative skin disease characterised by excessive growth of keratinocytes. Indeed, inducing keratinocyte apoptosis is a key mechanism responsible for psoriatic plaques clearance following some important existing therapies, which display pro-oxidant activity. Cold atmospheric plasma (CAP), acting as a tuneable source of reactive oxygen and nitrogen species (RONS), can controllably transfer RONS to the cellular environment, deliver antiproliferative RONS concentrations and exert antiproliferative and proapoptotic effects. This study was undertaken to evaluate the therapeutic potential of CAP in psoriasis. We used cell models of psoriasis-like inflammation by adding lipopolysaccharide (LPS) or tumour necrosis factor alpha (TNF-α) to HaCaT keratinocytes. Indirect plasma, plasma-activated medium (PAM), was administered to HaCaT cells. Atmospheric pressure plasma jet (APPJ) was applied directly to imiquimod (IMQ)-induced psoriasiform dermatitis in mice. The results showed that PAM induced an increase in intracellular ROS and caused keratinocyte apoptosis. Moreover, cells under inflammation showed lesser viability and larger apoptosis rate. With repeated administration of APPJ, psoriasiform lesions showed ameliorated morphological manifestation and reduced epidermal proliferation. Overall, this study supports that CAP holds good potential in psoriasis treatment.

Abstract
Psoriasis is a chronic inflammatory systemic disease characterized by a wide range of comorbidities. Respiratory comorbidities are currently poorly characterized and with discordant results. The systemic state of inflammation caused by psoriasis acts de novo on respiratory tissues and amplifies preexisting inflammation from asthma or chronic obstructive pulmonary disease. Because the lungs act as a gas exchanger between the internal and external environment, the impact of chronic psoriasis inflammation may be easily assessed through the analysis of exhaled breath. The fraction of exhaled nitric oxide test (FeNO) is a potential noninvasive solution that can provide quantitative and qualitative indices of respiratory airway inflammation. FeNO is routinely used to screen and manage asthmatic patients. Recent pilot studies contain encouraging data that underscore its possible use with systemic inflammatory nonpulmonary diseases, such as psoriasis. FeNO may therefore be a useful tool to evaluate underestimated airway inflammation and at the same time globally evaluate the impact of systemically antipsoriatic therapies.

Abstract
The innate immune components that modulate allergic contact hypersensitivity (CHS) responses are poorly defined. Using human skin from contact dermatitis patients and a mouse model of CHS, we find that hapten allergens disrupt the Arginase1 (Arg1) and inducible NO synthase (iNOS) dynamic in monocytes/macrophages (mono/MΦ), which renders those cells ineffectual in suppressing skin inflammation. Mice lacking Arg1 in MΦ develop increased CHS characterized by elevated ear thickening, mono/MΦ-dominated dermal inflammation, and increased iNOS and IL-6 expression compared with control mice. Treatment of Arg1flox/flox; LysMCre+/- mice with a selective NOS inhibitor or knockout of Nos2, encoding iNOS, significantly ameliorates CHS. Our findings suggest a critical role for Arg1 in mono/MΦ in suppressing CHS through dampening Nos2 expression. These results support that increasing Arg1 may be a potential therapeutic avenue in treating allergic contact dermatitis.

Abstract
Accurate diagnosis of cutaneous leishmaniasis (CL) is important for chemotherapy and epidemiological studies. Common approaches for Leishmania detection involve the invasive collection of specimens for direct identification of amastigotes by microscopy and the culturing of promastigotes from infected tissues. Although these techniques are highly specific, they require highly skilled health workers and have the inherent risks of all invasive procedures, such as pain and risk of bacterial and fungal super-infection. Therefore, it is essential to reduce discomfort, potential infection and scarring caused by invasive diagnostic approaches especially for children. In this report, we present a novel non-invasive method, that is painless, rapid and user-friendly, using sequential tape strips for sampling and isolation of DNA from the surface of active and healed skin lesions of CL patients. A total of 119 patients suspected of suffering from cutaneous leishmaniasis with different clinical manifestations were recruited and samples were collected both from their lesions and from uninfected areas. In addition, 15 fungal-infected lesions and 54 areas of healthy skin were examined. The duration of sampling is short (less than one minute) and species identification by PCR is highly specific and sensitive. The sequential tape stripping sampling method is a sensitive, non-invasive and cost-effective alternative to traditional diagnostic assays and it is suitable for field studies as well as for use in health care centers.

Abstract
The majority of studies on psoriasis have focused on explaining the genetic background and its associations with the immune system’s response. The aim of this study was to identify the low-molecular weight compounds contributing to the metabolomic profile of psoriasis and to provide computational models that help with the classification and monitoring of the severity of the disease. We compared the results from targeted and untargeted analyses of patients’ serums with plaque psoriasis to controls. The main differences were found in the concentrations of acylcarnitines, phosphatidylcholines, amino acids, urea, phytol, and 1,11-undecanedicarboxylic acid. The data from the targeted analysis were used to build classification models for psoriasis. The results from this study provide an overview of the metabolomic serum profile of psoriasis along with promising statistical models for the monitoring of the disease.

Abstract
Metabolomics is an emerging new "omics" field involving the systematic analysis of the metabolites in a biologic system. These metabolites provide a molecular snapshot of cellular activity and are thus important for understanding the functional changes in metabolic pathways that drive disease. Recently, metabolomics has been used to study the local and systemic metabolic changes in psoriasis and its cardiometabolic comorbidities. Such studies have revealed novel insights into disease pathogenesis and suggest new biochemical signatures that may be used as a marker of psoriatic disease. This review will discuss common strategies in metabolomics analysis, current findings in the metabolomics of psoriasis, and emerging trends in psoriatic metabolomics.

Abstract
BACKGROUND Cutaneous leishmaniasis (CL) in Iran is mainly caused by Leishmania major (L. major) and L. tropica. Arginase mediated L-arginine metabolism is an important issue in Leishmania parasite propagation. Arginase activity in human CL due to L. major and L. tropica have not been studied up to now. OBJECTIVES We aimed to compare the clinical and laboratory aspects of acute and chronic CL, focussing on arginase activity. METHODS In this case-control study, 30 patients with acute CL (duration ≤ 1 year), 13 patients with chronic CL (duration ≥ 2 year) and 11 healthy controls were recruited. Arginase activity was measured in skin biopsies of lesions, peripheral blood polymorphonuclear cells (PMNs), peripheral blood mononuclear cells (PBMCs) and plasma by standard methods. RESULTS The median of arginase activity in the acute lesions was higher than in chronic samples and significantly higher than in healthy controls (P = 0.008). PMNs of both acute and chronic patients showed higher levels of arginase activity as compared to the levels in PBMCs and plasma. The median of arginase activity in the PMNs of patients with chronic CL was higher than that of patients with acute CL and significantly higher than that of the healthy controls (P = 0.010). CONCLUSION The level of arginase activity in lesions of patients with acute and chronic CL was higher than the skin of healthy controls. The highest level of arginase activity was observed in PMNs from patients with chronic CL. This suggests that the high level of arginase activity in PMNs of patients with chronic CL may contribute to the chronicity.

Abstract
Psoriasis is characterized by uncontrolled proliferation and poor differentiation. Sirtuin1 (SIRT1) a class III deacetylase, crucial for differentiation in normal keratinocytes, is reduced in psoriasis. Down regulated SIRT1 levels may contribute to poor differentiation in psoriasis. In addition, the levels of early differentiation factors Keratin1 (K1) and Keratin10 (K10) are depleted in psoriasis. We attempted to study a possible effect of fructose, a SIRT1 upregulator and Propylthiouracil (PTU) to augment differentiation in psoriatic keratinocytes. Keratinocytes were cultured from lesional biopsies obtained from psoriatic patients and control cells were obtained from patients undergoing abdominoplasty. Cells were treated with fructose and PTU individually. K1 and K10 transcript levels were measured to evaluate early differentiation; SIRT1 protein expression was also studied to decipher its role in the mechanism of differentiation. The K1, K10 transcript levels, SIRT1 protein and transcript levels in fructose treated psoriatic keratinocytes were improved. This suggests keratinocyte differentiation was induced by fructose through SIRT1 upregulation. Whereas PTU induced differentiation, as confirmed by improved K1, K10 transcript levels followed a non-SIRT1 mechanism. We conclude that the use of fructose and PTU may be an adjunct to the existing therapies for psoriasis. Fructose induces differentiation of psoriatic keratinocytes through SIRT1 upregulation. Propylthiouracil (PTU) improves K1 and K10 to induce differentiation in psoriasis. Fructose and PTU can be used as adjunct to existing therapies for psoriasis.

Serum homocysteine, asymmetric dimethyl arginine (ADMA) and other arginine-NO pathway metabolite levels in patients with psoriasis. Arch Dermatol Res 2015; 307:439-44.

Abstract
Hyperhomocysteinemia, a well-known and independent risk factor for cardiovascular disease, has been related in several studies with psoriasis patients. It has been suggested that homocysteine leads to endothelial dysfunction by causing an accumulation of asymmetrical dimethyl arginine (ADMA), a potent endogenous nitric oxide (NO) synthase inhibitor of the L-arginine-NO pathway. However, limited data is available regarding the psoriasis and ADMA relationship. In this study, we aimed to investigate the serum levels of homocysteine, ADMA and other metabolites from the L-arginine-NO pathway in psoriasis patients. Forty-two patients with chronic plaque psoriasis and 48 controls were enrolled in the study. Serum homocysteine, ADMA, L-monomethyl-L-arginine (L-NMMA), symmetric dimethylarginine (SDMA) and L-arginine levels, and L-arginine/ADMA ratios of psoriasis patients and the control group were measured. The severity of psoriasis was assessed by the psoriasis area and severity index (PASI). The mean ADMA and homocysteine values were significantly higher, and citrulline and L-arginine/ADMA values were significantly lower in psoriasis patients compared to control subjects. However, there were no significant differences among the patient and control groups with respect to mean SDMA, L-NMMA and L-arginine values. PASI scores strongly correlated with the ADMA level and moderately correlated with L-arginine/ADMA ratio. This study suggests that the L-arginine-NO pathway metabolites, especially ADMA, may play an important role in the pathogenesis of psoriasis. Additionally, serum ADMA levels of psoriasis patients may be an indicator of the disease severity.

Abstract
![]()
Psoriasis is an immune-mediated highly
heterogeneous skin disease
in which genetic as well as environmental factors play important roles.
In spite of the local manifestations of the disease, psoriasis may
progress to affect organs deeper than the skin. These effects are
documented by epidemiological studies, but they are not yet mechanistically
understood. In order to provide insight into the systemic effects
of psoriasis, we performed a nontargeted high-resolution LC–MS
metabolomics analysis to measure plasma metabolites from individuals
with mild or severe psoriasis as well as healthy controls. Additionally,
the effects of the anti-TNFα drug Etanercept on metabolic profiles
were investigated in patients with severe psoriasis. Our analyses
identified significant psoriasis-associated perturbations in three
metabolic pathways: (1) arginine and proline, (2) glycine, serine
and threonine, and (3) alanine, aspartate, and glutamate. Etanercept
treatment reversed the majority of psoriasis-associated trends in
circulating metabolites, shifting the metabolic phenotypes of severe
psoriasis toward that of healthy controls. Circulating metabolite
levels pre- and post-Etanercept treatment correlated with psoriasis
area and severity index (PASI) clinical scoring (R2 = 0.80; p < 0.0001). Although the
responsible mechanism(s) are unclear, these results suggest that psoriasis
severity-associated metabolic perturbations may stem from increased
demand for collagen synthesis and keratinocyte hyperproliferation
or potentially the incidence of cachexia. Data suggest that levels
of circulating amino acids are useful for monitoring both the severity
of disease as well as therapeutic response to anti-TNFα treatment.

Abstract
Cofilin is an actin-binding protein that depolymerizes and/or severs actin filaments. This dual function of cofilin makes it one of the major regulators of actin dynamics important for T-cell activation and migration. The activity of cofilin is spatio-temporally regulated. Its main control mechanisms comprise a molecular toolbox of phospho-, phospholipid, and redox regulation. Phosphorylated cofilin is inactive and represents the dominant cofilin fraction in the cytoplasm of resting human T cells. A fraction of dephosphorylated cofilin is kept inactive at the plasma membrane by binding to phosphatidylinositol 4,5-bisphosphate. Costimulation via the T-cell receptor/CD3 complex (signal 1) together with accessory receptors (signal 2) or triggering through the chemokine SDF1α (stromal cell-derived factor 1α) induce Ras-dependent dephosphorylation of cofilin, which is important for immune synapse formation, T-cell activation, and T-cell migration. Recently, it became evident that cofilin is also highly sensitive for microenvironmental changes, particularly for alterations in the redox milieu. Cofilin is inactivated by oxidation, provoking T-cell hyporesponsiveness or necrotic-like programmed cell death. In contrast, in a reducing environment, even phosphatidylinositol 4,5-bisphosphate-bound cofilin becomes active, leading to actin dynamics in the vicinity of the plasma membrane. In addition to the well-established three signals for T-cell activation, this microenvironmental control of cofilin delivers a modulating signal for T-cell-dependent immune reactions. This fourth modulating signal highly impacts both initial T-cell activation and the effector phase of T-cell-mediated immune responses.

Abstract
Chronic nonhealing wounds in the elderly population are associated with a prolonged and excessive inflammatory response, which is widely hypothesized to impede healing. Previous studies have linked alterations in local L-arginine metabolism, principally mediated by the enzymes arginase (Arg) and inducible nitric oxide synthase (iNOS), to pathological wound healing. Over subsequent years, interest in Arg/iNOS has focused on the classical versus alternatively activated (M1/M2) macrophage paradigm. Although the role of iNOS during healing has been studied, Arg contribution to healing remains unclear. Here, we report that Arg is dynamically regulated during acute wound healing. Pharmacological inhibition of local Arg activity directly perturbed healing, as did Tie2-cre-mediated deletion of Arg1, revealing the importance of Arg1 during healing. Inhibition or depletion of Arg did not alter alternatively activated macrophage numbers but instead was associated with increased inflammation, including increased influx of iNOS(+) cells and defects in matrix deposition. Finally, we reveal that in preclinical murine models reduced Arg expression directly correlates with delayed healing, and as such may represent an important future therapeutic target.

Local increase of arginase activity in lesions of patients with cutaneous leishmaniasis in Ethiopia. PLoS Negl Trop Dis 2012; 6:e1684.

Abstract
Background Cutaneous leishmaniasis is a vector-borne disease that is in Ethiopia mainly caused by the parasite Leishmania aethiopica. This neglected tropical disease is common in rural areas and causes serious morbidity. Persistent nonhealing cutaneous leishmaniasis has been associated with poor T cell mediated responses; however, the underlying mechanisms are not well understood. Methodology/Principal Findings We have recently shown in an experimental model of cutaneous leishmaniasis that arginase-induced L-arginine metabolism suppresses antigen-specific T cell responses at the site of pathology, but not in the periphery. To test whether these results translate to human disease, we recruited patients presenting with localized lesions of cutaneous leishmaniasis and assessed the levels of arginase activity in cells isolated from peripheral blood and from skin biopsies. Arginase activity was similar in peripheral blood mononuclear cells (PBMCs) from patients and healthy controls. In sharp contrast, arginase activity was significantly increased in lesion biopsies of patients with localized cutaneous leishmaniasis as compared with controls. Furthermore, we found that the expression levels of CD3ζ, CD4 and CD8 molecules were considerably lower at the site of pathology as compared to those observed in paired PBMCs. Conclusion Our results suggest that increased arginase in lesions of patients with cutaneous leishmaniasis might play a role in the pathogenesis of the disease by impairing T cell effector functions. The leishmaniases are a complex of diseases caused by Leishmania parasites. Currently, the diseases affect an estimated 12 million people in 88 countries, and approximately 350 million more people are at risk. The leishmaniases belong to the most neglected tropical diseases, affecting the poorest populations, for whom access to diagnosis and effective treatment are often not available. Leishmania parasites infect cells of the immune system called macrophages, which have the capacity to eliminate the intracellular parasites when they receive the appropriate signals from other cells of the immune system. In nonhealing persistent leishmaniasis, lymphocytes are unable to transmit the signals to macrophages required to kill the intracellular parasites. The local upregulation of the enzyme arginase has been shown to impair lymphocyte effector functions at the site of pathology. In this study, we tested the activity of this enzyme in skin lesions of patients presenting with localized cutaneous leishmaniasis. Our results show that arginase is highly upregulated in these lesions. This increase in arginase activity coincides with lower expression of a signalling molecule in lymphocytes, which is essential for efficient activation of these cells. These results suggest that increased arginase expression in the localized cutaneous lesions might contribute to persistent disease in patients presenting with cutaneous leishmaniasis.

Abstract
A chronic inflammatory disease is a condition characterized by persistent inflammation. A number of human pathologies fall into this category, and a great deal of research has been conducted to learn more about their characteristics and underlying mechanisms. In many cases, a genetic component has been identified, but also external factors like food, smoke, or environmental pollutants can significantly contribute to worsen their symptoms. Accumulated evidence clearly shows that chronic inflammatory diseases are subjected to a redox control. Here, we shall review the identity, source, regulation, and biological activity of redox molecules, to put in a better perspective their key-role in cancer, diabetes, cardiovascular diseases, atherosclerosis, chronic obstructive pulmonary diseases, and inflammatory bowel diseases. In addition, the impact of redox species on autoimmune disorders (rheumatoid arthritis, systemic lupus erythematosus, psoriasis, and celiac disease) and neurodegenerative diseases (Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, and multiple sclerosis) will be discussed, along with their potential therapeutic implications as novel drugs to combat chronic inflammatory disorders.

Abstract
Nitric oxide (NO) is a potent regulator of keratinocyte growth and differentiation that has been implicated in the pathogenesis of psoriasis (Ps). The NOS3 -786 T/C (SNP id rs2070744; http://www.ensembl.org ), intron 4 variable number tandem repeat (VNTR), and Glu298Asp (SNP id rs1799983) polymorphisms, have been associated with differences in NO plasma concentrations and with the risk of hypertension (HT) and ischemic cardiac disease. The aim of this study was to determine whether the above-mentioned NOS3 variants contributed to the risk of Ps, and were associated with the risk for HT and CAD in these patients. A total of 368 patients with chronic plaque Ps and 400 healthy controls were genotyped for the NOS3 -786 T/C, intron 4 VNTR, and Glu298Asp polymorphisms. Carriers of the -786 C allele were significantly more frequent among the patients (p < 0.001). Carriers of the 4-repeats allele (45 + 44 genotypes) were also more frequent a (p < 0.001). No significant difference was found for the Glu298Asp polymorphism. None of the NOS3 variants was associated with Ht and CAD in our population. In conclusion, NOS3 gene polymorphism would be risk factors for developing Ps.
