Abstract
The pathogenesis of psoriasis is complex. Aryl hydrocarbon receptor (AhR) is a transcription factor that can be bound and activated by structurally diverse ligands and plays an important role in a range of biological processes and in the pathogenesis of different diseases. Recently, the role of AhR in psoriasis has attracted attention. AhR has toxicological functions and physiological functions. The overexpression and activation of AhR induced by the environmental pollutant and exogenous AhR agonist 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) can drive the development of psoriasis. This TCDD-mediated toxicological response disrupts the physiological functions of AhR resulting in skin barrier disorders and the release of inflammatory cytokines, 2 of the pivotal factors of psoriasis. In addition, highly upregulated kynureninase in psoriasis decreases endogenous AhR agonists, thereby weakening the physiological functions of AhR. Activating AhR physiological signalling should be useful in the treatment of psoriasis. Studies have demonstrated that physiological activation of AhR can dampen the severity of psoriasis. The oldest and effective treatment for psoriasis coal tar works by activating AhR, and both new anti-psoriasis drugs tapinarof and benvitimod are formulations of AhR agonist, supporting that activation of AhR can be used as a new strategy for the treatment of psoriasis. Preclinical and preliminary clinical studies have revealed the anti-psoriasis effects of a number of AhR agonists, providing potential candidates for the development of new drugs for the treatment of psoriasis.

Abstract
INTRODUCTION Plaque psoriasis, a chronic immune-mediated skin disorder, is characterized by well-demarcated erythematous plaques with silvery scales. This condition stems from complex interactions between genetic predisposition, immune dysregulation, and environmental triggers. Tapinarof downregulates the cytokine IL-17, diminishes the inflammatory infiltrate, and provides antioxidant properties while enhancing the expression of skin barrier proteins. AREAS COVERED This review begins by assessing tapinarof's mechanism in treating plaque psoriasis. Subsequently, it examines the effectiveness and safety of tapinarof 1% cream in adult patients. EXPERT OPINION Tapinarof 1% cream, which works by activating the aryl hydrocarbon receptor, is an FDA-approved treatment for adult plaque psoriasis. This therapy introduces a novel, nonsteroidal method for addressing inflammation and skin barrier issues, potentially serving as an alternative to conventional treatments. The once-daily, convenient cream formulation and favorable safety profile may enhance patient adherence, which is often poor with topical treatments. Tapinarof also maintains disease clearance for a mean of 4 months after treatment cessation.

Abstract
BACKGROUND Psoriasis is a chronic inflammatory genetic disease, mainly manifesting in the skin. Conventional therapies, such as glucocorticosteroids and corticosteroids, have adverse effects that limit drug use. Hence, it is imperative to identify a new therapeutic strategy that exhibits a favorable safety profile. Shi-Bi-Man (SBM) is a safe herbal supplement sourced from various natural plants, including ginseng, angelica sinensis, polygonum multiflorum, and aloe vera. PURPOSE We aimed to find a potential treatment for psoriasis and investigate the underlying mechanism through which SBM alleviates psoriatic-like skin inflammation in mice. METHODS We investigated the effects of supplementing with SBM through intragastric administration or smear administration in a murine model of imiquimod-induced psoriasis. The changes in body weight and Psoriasis Area and Severity Index (PASI) score were recorded throughout the entire process. Additionally, we used hematoxylin-eosin staining to observe the skin structure and performed single-cell RNA sequencing to explore the underlying mechanism of SBM in influencing the psoriasis-like phenotype. Immunofluorescence was conducted to verify our findings. Furthermore, reverse transcription-quantitative polymerase chain reaction (RT-qPCR) was employed to investigate the impact of Tetrahydroxy stilbene glycoside (TSG) on the expression levels of IL23 in HaCaT cells. RESULTS SBM remarkably alleviated the psoriasis-like phenotype by inhibiting IL-23/Th17 cell axis. Single-cell RNA sequencing analysis revealed a decrease in the expression of Il17 and Il23 in keratinocytes and T cells, concomitant with a reduction in the proportion of Th17 cells. Meanwhile, the activation of endothelial cells was inhibited, accompanied by a decrease in the expression of Cxcl16. In vitro, the addition of TSG to HaCaT cells resulted in significant suppression of IL23 expression stimulated by tumor necrosis factor-alpha (TNF-α).

J Invest Dermatol 2024; 144:509-519.e7. [PMID: 37734479 DOI: 10.1016/j.jid.2023.07.027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2022] [Revised: 07/05/2023] [Accepted: 07/22/2023] [Indexed: 09/23/2023]
Abstract
Tight junctions are involved in skin barrier functions. In this study, the expression of CLDN1, CLDN4, and OCLN was found to decrease in skin lesions of atopic dermatitis by bioinformatics analysis. Immunohistochemistry staining in skin specimens from 12 patients with atopic dermatitis and 12 healthy controls also showed decreased CLDN1, CLDN4, and OCLN expression in atopic dermatitis lesions. In vitro studies showed that IL-4 and IL-13 downregulated CLDN1, CLDN4, and OCLN expression in HaCaT cells as well as CLDN4 and OCLN expression in human primary keratinocytes. This effect, which was mediated through the Jak-signal transducer and activator of transcription 6 signaling pathway, increased paracellular flux of 4-kDa dextran. Benvitimod, a new drug for atopic dermatitis, upregulated CLDN4 and OCLN through the aryl hydrocarbon receptor/aryl hydrocarbon receptor nuclear translocator pathway. Benvitimod induced nuclear translocation of NRF2 and reduced production of ROS in keratinocytes, thus inhibiting IL-4-/IL-13-induced CLDN1 downregulation and signal transducer and activator of transcription 6 phosphorylation. These results indicate that T helper 2 cytokines are involved in tight junction impairment, and benvitimod can inhibit these effects.

Abstract
The introduction of biologic therapies has led to dramatic improvements in the management of moderate-to-severe psoriasis. Even though the efficacy and safety of the newer biologic agents are difficult to match, oral administration is considered an important advantage by many patients. Current research is focused on the development of oral therapies with improved efficacy and safety compared with available alternatives, as exemplified by deucravacitinib, the first oral allosteric Tyk2 inhibitor approved for the treatment of moderate to severe psoriasis in adults. Recent advances in our knowledge of psoriasis pathogenesis have also led to the development of targeted topical molecules, mostly focused on intracellular signaling pathways such as AhR, PDE-4, and Jak-STAT. Tapinarof (an AhR modulator) and roflumilast (a PDE-4 inhibitor) have exhibited favorable efficacy and safety outcomes and have been approved by the FDA for the topical treatment of plaque psoriasis. This revision focuses on the most recent oral and topical therapies available for psoriasis, especially those that are currently under evaluation and development for the treatment of psoriasis.

Abstract
Psoriasis is a chronic immune-mediated disorder that commonly affects adults and children. In recent years, pediatric psoriasis has increased in prevalence and the disease is often associated with various comorbidities and psychological distress. The conventional topical treatments for psoriasis, such as corticosteroids, calcineurin inhibitors, vitamin D analogs, anthralin, and coal tar, are often limited by their side effects, tolerability, and/or efficacy, particularly for use in children and on sensitive and intertriginous areas. Recently, the US Food and Drug Administration approved two new topical non-steroidal agents for treating psoriasis that target different pathogenic pathways than the conventional treatments. Roflumilast is a phosphodiesterase type 4 inhibitor approved for the treatment of plaque psoriasis in patients aged 12 years and older. Tapinarof is a novel aryl hydrocarbon receptor modulator approved for adult psoriasis and currently undergoing studies for pediatric psoriasis. Ongoing efforts are also being made to optimize conventional treatments, for instance, a new foam formulation of halobetasol propionate was recently approved for pediatric psoriasis. Clinical trials of various new drugs targeting one or multiple pathogenic pathways of psoriasis, such as Janus kinase inhibitors, different formulations of phosphodiesterase type 4 inhibitors, and aryl hydrocarbon receptor modulators have also been explored. The recent emergence of novel topical agents provides promising new options for managing pediatric psoriasis with the potential to improve clinical outcomes and quality of life. In this article, we review the mechanism of action, efficacy, and safety profile of novel topical agents and discuss their potential roles in the management of pediatric psoriasis.

Abstract
Tapinarof is an aryl hydrocarbon receptor (AHR) ligand which is used to treat plaque psoriasis in adults. However, the underlying mechanism is not yet fully understood. In this study, we applied two of the most studied psoriasis mouse models: topical application of imiquimod (IMQ) and subcutaneous injection of IL-23. Although both models successfully induced psoriasis-like lesions in mice, tapinarof had a completely opposite effect on the two models. Tapinarof decreased the expression of multiple essential cytokines involved in the pathological IL-23/IL-17/IL-22 axis and ameliorated IMQ-induced psoriatic dermatitis, inhibiting keratinocyte proliferation and abnormal differentiation. However, in the IL-23-injection-model, tapinarof instead aggravated the disease. Here, tapinarof increased epidermal thickness and differentiated epidermal dysplasia in mice. Our data suggest that tapinarof may have different effects on varied types of psoriasis.

Abstract
OBJECTIVE This article reviews the efficacy and safety of 1% tapinarof cream for plaque psoriasis. DATA SOURCES A literature search was conducted from August 2022 to February 2023. The terms tapinarof, VTAMA, benvitimod, GSK2894512, DMVT-505, and WBI-1001 were queried in PubMed. ClinicalTrials.gov was searched to identify ongoing or unpublished studies. STUDY SELECTION AND DATA EXTRACTION All clinical trials written in English and relevant to pharmacology, efficacy, and safety were included. DATA SYNTHESIS In two 12-week phase III clinical trials, disease severity assessed by a Physician's Global Assessment (PGA) score of clear or almost clear and a 2-point PGA improvement was 35.4% and 40.2% at week 12 in the 2 trials, respectively. In the 40-week, open-label extension trial, the efficacy and safety results were similar: 40.9% of patients achieved a PGA of 0 at least once during the trial, and 58.2% of patients with PGA ≥ 2 achieved PGA 0/1 at least once. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE IN COMPARISON TO EXISTING DRUGS Tapinarof is a topical aryl hydrocarbon receptor agonist and a first-in-class, potentially promising treatment for plaque psoriasis recently approved by the U.S. Food and Drug Administration. CONCLUSION Compared with placebo, tapinarof may be an effective and safe topical treatment for mild to severe plaque psoriasis. Head-to-head trials to compare the efficacy and adverse effect profile of tapinarof to other topical treatments are still needed, as are investigation in patients with recent or current use of phototherapy or biologic or nonbiologic systemics. Cost and adherence to treatment may be barriers for treatment efficacy.

Abstract
Tapinarof is a topical, aryl-hydrocarbon receptor agonist that has recently received FDA-approval for the treatment of psoriasis. This novel therapeutic has also been shown to be effective for atopic dermatitis and is currently in phase 3 for this indication. Beyond good efficacy and fast onset of action in patients with psoriasis, the clinical response to tapinarof is notable for durable remission or near remission, maintained for an average of 130 days beyond treatment discontinuation in patients with psoriasis in phase 3 studies. Tapinarof is usually well tolerated but can induce a follicular inflammatory reaction and dermatitis in some patients. This narrative review covers the historical development of this molecule, safety and efficacy data from clinical trials conducted with various topical formulations, and practical considerations derived from our 15 years of clinical trial experience with the drug.

Abstract
Benvitimod is a topical drug that has recently been approved for mild to moderate psoriasis and atopic dermatitis. The drug has just completed phase 3 trials for psoriasis, which calls for a systematic update of current evidence on the efficacy and safety of this drug. We searched MEDLINE (PubMed), EMBASE, Science Direct, International Clinical Trials Registry Platform (ICTRP), Cochrane Central Register of Controlled Trials, and Google Scholar for all available randomized controlled trials concerning the topic. We included six randomized controlled trials evaluating the efficacy of benvitimod 1.0% with a total of 1925 patients. Our meta-analysis demonstrated that more patients in the benvitimod group achieved physician global assessment score of 0 or 1 (RR 6.53, 95% CI 4.39-9.71), psoriasis area and severity index (PASI) 75 (RR 4.34, 95% CI 2.96-6.36), PASI 90 (RR 8.83, 95% CI 5.22-14.95) and body surface area reduction (MD -3.85, 95% CI -4.83, -2.88) than placebo at week 12. Patient-reported outcomes were also analyzed, yielding a significant benefit in the benvitimod group for peak pruritus numerical rating scale (PP-NRS) score (MD -1.20, 95% CI -1.98, -0.42), ≥4-point decrease in PP-NRS score (RR 1.58, 95% CI, 1.24-2.03) and dermatology life quality index score (MD -2.54, 95% CI -4.00, -1.07). There was a significantly higher incidence of adverse events in the benvitimod group compared to placebo (RR 1.98, 95% CI 1.73-2.27), while the risk was found to be non-significant for serious adverse events. Benvitimod is an effective treatment of psoriasis as compared to a placebo. However, more large-scale, high-quality trials are needed to comment on the safety of this drug.

Abstract
Psoriasis is considered an autoimmune, inflammatory disorder with a genetic basis. The underlying aetiology is yet unclear. Evidence suggests the congregation of immune cells and their secreted inflammatory cytokines, leukocytes, and other inflammation-promoting factors in large amounts within the epidermal layers of the skin, driving an inflammatory milieu. Although psoriasis is not a fatal condition, patients experience severe pain and suffering. It has a debilitating effect on the physiological and psychological state of the patient. Its distinguishing features are inflammation, formation of plaques on the skin and hyperproliferation of keratinocytes. Therapeutic strategies for treating psoriasis witnessed a radical improvement from traditional therapies to the approval of specific therapies like biologics and small molecules. The emerging evidence about new pharmacological targets and mechanisms in psoriasis has widened the scope for expanding therapeutic strategies. Our review discusses the existing treatments for plaque psoriasis and updates on therapies based on novel pharmacological targets in clinical development.

Yang Y, Zhang Y, Chen X, Su Z, Deng Y, Zhao Q. Khasianine ameliorates psoriasis-like skin inflammation and represses TNF-α/NF-κB axis mediated transactivation of IL-17A and IL-33 in keratinocytes. JOURNAL OF ETHNOPHARMACOLOGY 2022; 292:115124. [PMID: 35183690 DOI: 10.1016/j.jep.2022.115124] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/25/2021] [Revised: 02/11/2022] [Accepted: 02/14/2022] [Indexed: 06/14/2023]
Abstract
ETHNO-PHARMACOLOGICAL RELEVANCE Khasianine is recently identified as a bioactive compound from Solanum nigrum L. (SNL) which is a traditional Chinese herb (named LongKui in China) and has been clinically applied for treating psoriasis in China but with limited knowledge about the active ingredients. AIM OF THE STUDY This study tried to explore the bioactivity of Khasianine and showed that Khasianine possessed highly anti-inflammatory bioactivity which rapidly alleviated psoriasis-like mice skin inflammation. MATERIALS AND METHODS Imiquimod induced psoriasis-like mouse model, and human keratinocytes were employed in this study. In vivo, immunohistochemistry and immunofluorescence were performed to evaluate the pathological improvement in psoriatic lesions after Khasianine treatment. In vitro, tumor necrosis factor α (TNF-α) treated HaCaT cells with or without Khasianine, were used to analyze the expression and cellular location of NF-κB p65, the expression of IL-17A and IL-33, and the binding intensity of NF-κB p65 on the promoter of IL-17A and IL-33 to understand the molecular mechanism of Khasianine mediated anti-inflammatory effect. RESULTS Khasianine reduced infiltration of CD4+ T helper cells (Th cells) and macrophages in mice psoriatic lesions. Immunohistochemistry analysis revealed that Khasianine reduced TNF-α levels in lesions and suppressed NF-κB p65 activation as well as expression of IL-17A and IL-33 in mice epidermal keratinocytes. Further studies in human keratinocytes demonstrated that Khasianine inhibited TNF-α-induced transcriptional activation (transactivation) of NF-κB p65 such as evicting NF-κB p65 binding from the promoter regions of IL-17A and IL-33 and preventing NF-κB nuclear translocation. CONCLUSIONS Our results suggested that Khasianine is a potent anti-inflammatory compound with the bioactivity of NF-κB inhibition and is a promising candidate for psoriasis topical therapy.

Abstract
Aryl hydrocarbon receptor (AHR)/nuclear factor-erythroid 2-related factor 2 (NRF2) modulation are emerging as novel targets in the treatment of atopic dermatitis and other inflammatory skin disorders. Agonist activation of this pathway has downstream effects on epidermal barrier function, immunomodulation, oxidative stress reduction, and cutaneous microbiome modulation. Tapinarof, a dual agonist of the AHR/NRF2 signaling pathway, has shown promise in phase 2 trials for atopic dermatitis. In this review, we summarize current knowledge of the AHR/NRF2 pathway and implications in skin disease process. We also review the therapeutic potential of current AHR agonists and propose future directions to address knowledge gaps.

Abstract
Psoriasis is a chronic immune-mediated skin disease with a significant impact on patients' quality of life. Mild-to-moderate forms of the disease usually require long-term topical treatment, but prolonged use of corticosteroids and vitamin D analogues is limited by adverse effects. With further understanding of psoriasis pathogenesis, new molecules are emerging aiming to fulfil these clinical needs. Tapinarof, an aryl hydrocarbon receptor modulator, has completed a phase III study and demonstrated good efficacy results, even in long treatment courses, with a favourable safety profile. It additionally appears to have a promising remitting effect as patients presented with an average relapsing time of over 3 months. Roflumilast, a phosphodiesterase type 4 inhibitor, also underwent a phase III study with significant lesion improvement and notable pruritus management, and with no reported side effects. Roflumilast was evaluated as an option for intertriginous areas with good outcomes in a small sample, but larger trials are required. The Janus kinase-signal transducer and activator of transcription pathway has been targeted in recent clinical investigations with promising options, currently with brepocitinib pending phase IIb results. Ongoing preclinical studies involving interleukin-2 inhibition, RNA modulators and amygdalin analogues may lead to forthcoming clinical trials. New topical drugs are successfully emerging and future research comparing them to classical options will dictate their clinical role in the treatment of psoriasis.

Abstract
BACKGROUND We conducted this systematic review to clarify the efficacy and safety of benvitimod on psoriasis. METHODS We searched the databases of PubMed, China National Knowledge infrastructure, Cochrane Library, Embase, Web of science to identify randomized controlled trials (RCTs) of benvitimod on psoriasis up to April 2021. RESULTS Five RCTs of benvitimod on psoriasis were included. A total of 1237 patients were included. 0.5% or 1.0% benvitimod was applied topically once or twice a day. More patients in benvitimod group achieved PASI 90, PASI 75, PASI 50 and BSA reduction than placebo at Week 12. More patients in benvitimod group achieved PGA 0 or 1 than placebo since Week 6. There were no statistical significances in efficacies of benvitimod at different concentrations and frequencies. CONCLUSIONS Benvitimod was effective and safe for psoriasis. More RCTs with high qualities are needed to further verify the current conclusion.

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.
