Gan HH, Yang G, Shen TT. Efficacy of acupoint injection in the treatment of chronic eczema and its influence on peripheral blood T cells. World J Clin Cases 2024; 12:3019-3026. [DOI: 10.12998/wjcc.v12.i17.3019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/29/2024] [Revised: 04/17/2024] [Accepted: 04/19/2024] [Indexed: 06/04/2024] Open
Abstract
BACKGROUND Chronic eczema significantly impacts daily life, social interactions, and quality of life; however, no curative treatment has been identified.
AIM To determine the clinical efficacy of acupoint injection for chronic eczema and its influence on peripheral blood T cells.
METHODS Eighty patients with chronic eczema treated at our hospital between June 2022 and March 2023 were randomly assigned to a control group (n = 40), which received conventional Western medicine treatment, or an observation group (n = 40), which received routine Western medicine treatment plus acupoint injection of triamcinolone acetonide. Response and adverse reaction rates, as well as differences in the levels of serum cytokines IFN-γ, IL-2, IL-4, and IL-10 before and after treatment were investigated.
RESULTS No difference in overall response rates were found between the observation and control groups (100% vs 90%, respectively; P > 0.05); however, the observation group had a higher marked response rate than the control group (87.5% vs 52.5%; P < 0.05). Both groups had decreased Eczema Area and Severity Index scores and increased pruritus after treatment (P < 0.05), particularly in the observation group (P < 0.05). The observation group had an adverse reaction rate of 2.5% (1/40), which did not differ significantly from that of the control group (P > 0.05). The observation group exhibited higher post-treatment INF-γ and IL-2 but lower IL-4 levels than the control group (P < 0.05); however, no significant inter-group difference was observed in post-treatment IL-10 levels (P > 0.05).
CONCLUSION Acupoint injection of triamcinolone acetonide is safe and effective in treating chronic eczema. Its therapeutic mechanism is related to the regulation of peripheral blood T cell levels, inhibition of inflammatory reactions, and mitigation of immune imbalance.

Abstract
Objective To evaluate whether α-ionone, an aromatic compound mainly found in raspberries, carrots, roasted almonds, fruits, and herbs, inhibits UVB-mediated photoaging and barrier dysfunction in a human epidermal keratinocyte cell line (HaCaT cells). Methods The anti-photoaging effect of α-ionone was evaluated by detecting the expression of barrier-related genes and matrix metalloproteinases (MMPs) in HaCaT cells. The levels of reactive oxygen species, oxidation product, antioxidant enzyme, and inflammatory factors were further analysed to underline the protective effect of α-ionone on epidermal photoaging. Results It was found that α-ionone attenuated UVB-induced barrier dysfunction by reversing keratin 1 and filaggrin in HaCaT cells. α-Ionone also reduced the protein amount of MMP-1 and mRNA expression of MMP-1 and MMP-3 in UVB-irradiated HaCaT cells, implying protective effects on extracellular matrix. Furthermore, HaCaT cells exposed to α-ionone showed significant decreases in interleukin (IL)-1β, IL-6, IL-8, and tumor necrosis factor-α as compared to UVB-irradiated HaCaT cells. α-Ionone treatment significantly inhibited the UVB-induced intracellular reactive oxygen species increase and malondialdehyde accumulation. Therefore, the beneficial effects of α-ionone on inhibiting MMPs secretion and barrier damage may be related to attenuated inflammation and oxidative stress. Conclusion Our results highlight the protective effects of α-ionone on epidermal photoaging and promote its clinic application as a potential natural anti-photodamage agent in future.

Abstract
The main function of the skin is to protect the body from negative environmental influences. The physical barrier permeability is mainly represented by the stratum corneum; however, other layers of the epidermis and the dermis are its important components. The mechanical strength of the skin is provided by intercellular contacts in the epidermis and structural proteins of the dermis. The chemical-biological barrier includes lipids, acids, natural moisturizing factor and antimicrobial peptides. Mucosal immunity system creates a barrier against infection. The microflora of healthy skin counteracts its colonization by pathogens and is vital for its immune functions. Physiological processes in the skin are closely related. A violation in one of them often leads to the formation of a whole cascade of pathological reactions affecting all the links of its protection. Vitamins A, D and E are used to correct impaired barrier function of the skin. The most pronounced effect of vitamin A (retinol palmitate) is the proliferation of epidermal cells and synthesis of extracellular matrix structures of the dermis; vitamin D (cholecalciferol) regulation of differentiation and suppression of excessive proliferation of keratinocytes; vitamin E (tocopherol acetate) antioxidant effect. The combined use of these vitamins in the composition of RadevitActive ointment affects all the main elements of the protection of the epidermis and dermis: strengthens the mechanical strength of the stratum corneum and dermis, stabilizes chemical and physical protection, including prevents the penetration of foreign substances and microorganisms, reduces transepidermal loss of water and electrolytes, reduces the damaging effect of UV, increases antimicrobial and antioxidant protection.

Abstract
INTRODUCTION The vulnerable skin of neonates and infants is still developing anatomically and functionally and more susceptible to skin barrier disruption. The current consensus paper explores challenges in caring for neonates and infants' skin, skincare use and evaluates the role of ceramides (CERs) containing cleansers and moisturizers. EVIDENCE AQUISITION A panel of eight clinicians who treat neonates and infants developed a consensus paper on new-born and infant skin barrier integrity and CERs-containing skincare importance. The consensus process consisted of a modified Delphi technique. The selected information from the literature searches, coupled with the panel's opinion and experience, was used to adopt statements to provide clinical data for paediatric dermatologists, dermatologists, and paediatric healthcare providers who treat neonates and infants. EVIDENCE SYNTHESIS Increasingly, evidence supports skincare starting early in life, recognizing the benefits of ongoing daily use of non-alkaline cleansers and moisturizers to maintain skin barrier function. Skincare for neonates and infants should be safe, effective, and fragrance as well as sensitizing agent-free. Skincare with CERs may benefit the stratum corneum's lipid and water content. CONCLUSIONS When applied from birth onwards, gentle cleansers and moisturizers containing barrier lipids help maintain the protective skin barrier and soothe the skin with long-term moisturizing benefits.

Abstract
Diet has long been understood to have an intricate association with atopic dermatitis, although much remains unelucidated. Skin barrier dysfunction with dysbiosis and consequent impairment of immune tolerance likely underly the pathogenesis of coincident atopic dermatitis and food allergy. There is a wide range of possible skin reactions to food, complicating the diagnosis and understanding of food allergies. Many patients, parents, and providers incorrectly suspect diet as causative of atopic dermatitis symptoms and many have tried elimination diets. This frequently leads to inaccurate labeling of food allergies, contributing to a dangerous spiral of inappropriate testing, referrals, and dietary changes, while neglecting established atopic dermatitis treatment essentials. Alternatively, certain dietary supplements or the introduction of certain foods may be beneficial for atopic dermatitis management or prevention. Greater consensus on the role of diet among providers of patients with atopic dermatitis is strongly encouraged to improve the management of atopic dermatitis.

Abstract
OBJECTIVE Sensitive skin is characterized by self-reported sensory perceptions in response to stimuli that should not provoke unpleasant sensations. Cosmetic products for sensitive skin are designed to minimize these symptoms. This study aimed to unveil the most used active ingredients for sensitive skin in facial care products from the pharmacy and parapharmacy channel. METHODS A pool of products from the pharmacy and parapharmacy channel whose label included the expressions 'sensitive skin', 'reactive skin' or 'intolerant skin' were analysed. The active ingredients were identified from product compositions and ranked in descending order of occurrence. The scientific evidence regarding the mechanism of action and efficacy of each ingredient was also compiled. RESULTS Eighty-eight products from 19 multinational brands were included. Niacinamide leads the top, followed by Avena sativa, allantoin, glycyrrhetinic acid and derivatives and Laminaria ochroleuca. Ingredients that can reduce skin inflammation and act on the skin barrier were used in more than half of the products analysed. The clinical studies regarding the active ingredients used in these products remain sparse and lack methodological quality. Among the top ingredients, niacinamide, panthenol and acetyl dipeptide-1 cetyl ester were the only ones studied on volunteers having sensitive skin, while acetyl dipeptide-1 cetyl ester and palmitoyl tripeptide-8 were designed to act on the molecular targets involved in this condition. CONCLUSION This study reveals the most used active ingredients in cosmetic products for sensitive skin, as well as the scientific evidence supporting their efficacy and the mechanisms of action. This insight is meaningful for dermatologists and other health professionals to provide customized advice based on the symptomatology of individuals with sensitive skin, and for the formulation of cosmetic products and design of new active ingredients.

Abstract
BACKGROUND Despite the invention of various non-invasive bioengineering tools, skin-type analysis has largely been based on subjective assessments. However, advancements in the functional cosmetic industry and artificial intelligence-assisted dermatology are creating a greater demand for an objective skin-type classification system. OBJECTIVES To propose an objective skin-type classification system solely based on non-invasive, bioengineering devices; provide reference values applicable to the Korean population; and compare our reference values with those of published studies. METHODS Biophysical parameter measurements were obtained from the 2018 International Skin Characteristics Data Bank Project conducted by the Foundation of Korea Cosmetic Industry Institute. The participants were 434 healthy South Korean adults. Each participant was assessed using eight bioengineering devices (Tewameter® , pH-meter® , Corneometer® , Sebumeter® , Cutometer® , Spectrophotometer® , PRIMOS® lite, and Janus® ). The measurements were divided into tertiles to determine reference points. RESULTS Our objective skin-type classification consists of five main categories (sensitivity, hydration, oiliness, elasticity, and skin tone) and five corresponding subcategories (erythema, roughness, pores, wrinkles, and pigmentation, respectively). Each skin type was assigned based on the reference point of the biophysical parameter, which was established as the tertile value associated with 'unfavourable' skin characteristics. Individuals were categorized as having sensitive skin when the TEWL scores were over 18.0 g/m2 /h or the pH was over 5.45; dehydrated skin when the corneometric value measured below 47.17 A.U.; oily skin when the sebumetric value exceeded 70 μg/cm2 ; and loose skin when the cutometric R2 value was below 0.68 E/mm. CONCLUSIONS This study is the first to provide a comprehensive skin-type classification system based solely on non-invasive biophysical parameters. As measurement data accumulate, the reference points will progress to become more accurate, and they will be subdivided according to gender, age, and ethnic group. Therefore, our classification system serves as a basis for artificial intelligence-based skin-type analysis.

Abstract
Skin photoaging is mainly induced by ultraviolet (UV) irradiation and its manifestations include dry skin, coarse wrinkle, irregular pigmentation, and loss of skin elasticity. Dietary supplementation of nutraceuticals with therapeutic and preventive effects against skin photoaging has recently received increasing attention. This article aims to review the research progress in the cellular and molecular mechanisms of UV-induced skin photoaging. Subsequently, the beneficial effects of dietary components on skin photoaging are discussed. The photoaging process and the underlying mechanisms are complex. Matrix metalloproteinases, transforming growth factors, skin adipose tissue, inflammation, oxidative stress, nuclear and mitochondrial DNA, telomeres, microRNA, advanced glycation end products, the hypothalamic-pituitary-adrenal axis, and transient receptor potential cation channel V are key regulators that drive the photoaging-associated changes in skin. Meanwhile, mounting evidence from animal models and clinical trials suggests that various food-derived components attenuate the development and symptoms of skin photoaging. The major mechanisms of these dietary components to alleviate skin photoaging include the maintenance of skin moisture and extracellular matrix content, regulation of specific signaling pathways involved in the synthesis and degradation of the extracellular matrix, and antioxidant capacity. Taken together, the ingestion of food-derived functional components could be an attractive strategy to prevent skin photoaging damage.

Abstract
Background: The alpha7 nicotinic acetylcholine receptor (Chrna7) plays an essential anti-inflammatory role in immune homeostasis and was recently found on mast cells (MC). Psychosocial stress can trigger MC hyperactivation and increases pro-inflammatory cytokines in target tissues such as the skin. If the cholinergic system (CS) and Chrna7 ligands play a role in these cascades is largely unknown. Objective: To elucidate the role of the CS in the response to psychosocial stress using a mouse-model for stress-triggered cutaneous inflammatory circuits. Methods: Key CS markers (ACh, Ch, SLURP-1, SLURP-2, Lynx1, Chrm3, Chrna7, Chrna9, ChAT, VAChT, Oct3, AChE, and BChE) in skin and its MC (sMC), MC activation, immune parameters (TNFα, IL1β, IL10, TGFβ, HIF1α, and STAT3) and oxidative stress were analyzed in skin from 24 h noise-stressed mice and in cultured MC (cMC) from C57BL/6 or Chrna7-Knockout mice. Results: First, Chrna7 and SLURP-1 mRNA were exclusively upregulated in stressed skin. Second, histomorphometry located Chrna7 and SLURP-1 in nerves and sMC and demonstrated upregulated contacts and increased Chrna7+ sMC in stressed skin, while 5 ng/mL SLURP-1 degranulated cMC. Third, IL1β+ sMC were high in stressed skin, and while SLURP-1 alone had no significant effect on cMC cytokines, it upregulated IL1β in cMC from Chrna7-KO and in IL1β-treated wildtype cMC. In addition, HIF1α+ sMC were high in stressed skin and Chrna7-agonist AR-R 17779 induced ROS in cMC while SLURP-1 upregulated TNFα and IL1β in cMC when HIF1α was blocked. Conclusions: These data infer that the CS plays a role in the regulation of stress-sensitive inflammatory responses but may have a surprising pro-inflammatory effect in healthy skin, driving IL1β expression if SLURP-1 is involved.

Abstract
With a fascinating complexity, governed by multiple physiological processes, the skin is considered a mantle with protective functions which during lifetime are frequently impaired, triggering dermatologic disorders. As one of the most prevalent dermatologic conditions worldwide, characterized by a complex pathogenesis and a high recurrence, acne can affect the patient's quality of life. Smart topical vehicles represent a good option in the treatment of a versatile skin condition. By surpassing the stratum corneum known for diffusional resistance, a superior topical bioavailability can be obtained at the affected place. In this direction, the literature study presents microemulsions as a part of a condensed group of modern formulations. Microemulsions are appreciated for their superior profile in matters of drug delivery, especially for challenging substances with hydrophilic or lipophilic structures. Formulated as transparent and thermodynamically stable systems, using simplified methods of preparation, microemulsions have a simple and clear appearance. Their unique structures can be explained as a function of the formulation parameters which were found to be the mainstay of a targeted therapy.

Abstract
Appropriate skincare is essential in the prevention and management of rosacea. We sought to investigate whether cleansing habits, the initial step of skin care, would influence the onset and progression of rosacea and their associations with clinical features of rosacea in the Chinese population. We analyzed the daily cleansing habits data collected from 999 rosacea cases and 1010 skin-healthy controls from China. Overall, the high frequency of cleansing (more than once daily) (OR = 1.450) and the large amount of cleansers (> 5 pieces/year) (OR = 1.612) presented a positive correlation with rosacea occurring. The cleansing duration and types of cleansers appeared not to be correlated with the onset of rosacea in this study. Significant risk factors also included the deep cleansing habits, such as the overuse of cleansing tool (more than four times/week) (OR 2.179) and oil control and exfoliating behaviors via daily used products (OR 2.435), facial mask (OR 1.459) or projects in beauty salons (OR 2.688). The analysis of the clinical features of rosacea showed that patients who prefer deep cleansing were more prone to present an initial symptom of papule and pustule (OR 1.63-3.15). What is more, using daily exfoliating products presented a positive correlation with the progression of the symptoms from flushing to erythema (OR = 2.01), papule and pustule (OR = 2.28) and telangiectasis (OR = 2.14), and the affected areas from a single area to pan facial (OR = 1.650). In conclusion, excessive cleansing habits were substantial risk factors for the incidence and progression of rosacea in the Chinese population.

Abstract
BACKGROUND The human skin organ culture (hSOC) developed a century ago has been widely used to study various aspects of human skin development, differentiation, function, disease as well as skin appendages biology, however, maintaining the integrity of epidermal structure in long-term culture, has remained a challenge. OBJECTIVES Here we tried to establish a culture system using supplemented William's E medium in the presence of a ROCK inhibitor Y-27632 to maintain epidermal architecture in the long-term hSOC and to investigate the underlying mechanisms. METHODS Human breast skins, cut into 5 mm × 5 mm pieces, were cultured in supplemented William's E medium in the presence of 30μM Y-27632. The cultured skin tissues were collected at different time points for analysis of epidermal cell proliferation and differentiation by real time qRT-PCR and immunofluorescence (IF) staining. The keratinocyte suspension assay and in vivo treatment of Y-27632 on mouse were also carried out to study that the regulation of Y-27632 on keratinocyte proliferation and differentiation. RESULTS We found Y-27632 not only enhanced both basal cell proliferation and expression of suprabasal cell differentiation markers, but also maintained the balance of keratinocyte proliferation and differentiation through activation of AKT pathways on one hand and inhibition of ERK pathways on the other hand. The AKT inhibitor MK-2206 blocked the epidermal preservation effect of Y-27632, while the MEK/ERK inhibitor U0126 enhanced the preservation of epidermal structure in the hSOC. CONCLUSIONS Y-227632 can maintain skin epidermal integrity through regulation of AKT and ERK activity in the hSOC.

Abstract
Background The frequency of dermatological acts is increasing. These procedures often cause injuries and traumatic alterations in specific skin layers, slowing down wound healing. Patients and methods An open observational study lasting 1 month was conducted on 2,363 patients who had undergone various dermatological procedures. This study was conducted in eight European countries and an Asian country during which the tolerance and efficacy of a cosmetic cream based on Rhealba oat plantlets’ extract, l-ALA–l-GLU dipeptide, and hyaluronic acid were assessed on patients’ wounds. Results Efficacy was observed 5′ after the first application, which leads to an immediate relief, confirmed by the overall efficacy judged by the doctors as good or very good in 96.8% of the cases. In Germany, the efficacy of the same cream was assessed on children suffering from first- or second-degree burns. In this dermatopediatric case, the aim was to support the regeneration process and prevent scarring by using a topical cream rather than a silicon bandage or corticosteroids. A positive effect on skin regeneration and prevention of scaring could already be observed after 4 weeks of application without any undesired complication. Conclusion This clinical focus complements the previous meta-analysis by demonstrating that the tested cream containing Rhealba oat plantlets’ extracts, l-ALA–l-GLU dipeptide, and hyaluronic acid could also be used with a great efficacy in children after thermal burns to prevent scaring.

Abstract
This guideline was developed as a joint interdisciplinary European project, including physicians from all relevant disciplines as well as patients. It is a consensus-based guideline, taking available evidence from other guidelines, systematic reviews and published studies into account. This second part of the guideline covers antimicrobial therapy, systemic treatment, allergen-specific immunotherapy, complementary medicine, psychosomatic counselling and educational interventions, whereas the first part covers methods, patient perspective, general measures and avoidance strategies, basic emollient treatment and bathing, dietary intervention, topical anti-inflammatory therapy, phototherapy and antipruritic therapy. Management of AE must consider the individual clinical variability of the disease. Systemic immunosuppressive treatment with cyclosporine, methotrexate, azathioprine and mycophenolic acid is established option for severe refractory cases, and widely available. Biologicals targeting the T helper 2 pathway such as dupilumab may be a safe and effective, disease-modifying alternative when available. Oral drugs such as JAK inhibitors and histamine 4 receptor antagonists are in development. Microbial colonization and superinfection may cause disease exacerbation and can require additional antimicrobial treatment. Allergen-specific immunotherapy with aeroallergens may be considered in selected cases. Psychosomatic counselling is recommended especially in stress-induced exacerbations. Therapeutic patient education ('Eczema school') is recommended for children and adult patients. General measures, basic emollient treatment, bathing, dietary intervention, topical anti-inflammatory therapy, phototherapy and antipruritic therapy have been addressed in the first part of the guideline.

Abstract
BACKGROUND Fragile skin is a poorly understood skin condition, particularly in the general adult population. There are currently limited epidemiological data on the prevalence of fragile skin in adults. The objectives of this study were to assess the prevalence of perceived fragile skin across different skin types in representative samples of the general adult populations in Mexico and Russia, and to identify skin characteristics associated with perceived fragile skin. METHODS Two identical cross-sectional surveys, using a short online self-administered questionnaire, were conducted on samples of recruited individuals that were representative of the general Mexican and Russian populations. Participants responded to questions about fragile skin, with the main question being "In your opinion, do you have fragile skin (ie, skin less resistant and reacting quickly to external aggressions)?". The survey also covered questions relating to skin appearance, skin symptoms, skin disease, dermatological procedures, and living environment and climate. RESULTS Overall, 1,210 individuals in Mexico (N=606) and Russia (N=604) completed the online survey. Fragile skin was perceived in 50.0% and 45.9% of participants in Mexico and Russia, respectively. The principal skin appearance characteristics reported by individuals with perceived fragile skin were thin, easily wrinkled, and transparent; the main skin symptoms were dryness, redness, and/or itching (≥50% of individuals in Mexico), and dryness, tightness, and/or redness (>60% of individuals in Russia). Individuals with perceived fragile skin had experienced skin disease and/or undergone a dermatological procedure in the past 12 months, and they reported being exposed to stress (>80% of individuals in both surveys). CONCLUSION A substantial proportion of the general adult population of Mexico and Russia perceived that they had fragile skin, regardless of their skin type; fragile skin was perceived more frequently in women. These findings should assist dermatologists to extend their understanding and management of individuals with perceived fragile skin.

Abstract
Within their first days of life, newborns' skin undergoes various adaptation processes needed to accommodate the transition from the wet uterine environment to the dry atmosphere. The skin of newborns and infants is considered as a physiological fragile skin, a skin with lower resistance to aggressions. Fragile skin is divided into four categories up to its origin: physiological fragile skin (age, location), pathological fragile skin (acute and chronic), circumstantial fragile skin (due to environmental extrinsic factors or intrinsic factors such as stress) and iatrogenic fragile skin. Extensive research of the past 10 years have proven evidence that at birth albeit showing a nearly perfect appearance, newborn skin is structurally and functionally immature compared to adult skin undergoing a physiological maturation process after birth at least throughout the first year of life. This article is an overview of all known data about fragility of epidermis in 'fragile populations': newborns, children and adolescents. It includes the recent pathological, pathophysiological and clinical data about fragility of epidermis in various dermatological diseases, such as atopic dermatitis, acne, rosacea, contact dermatitis, irritative dermatitis and focus on UV protection.

Abstract
Psoriasis and the spectrum of inflammatory bowel diseases (IBD) are chronic, inflammatory, organotropic conditions. The epidemiologic coexistence of these diseases is corroborated by findings at the level of disease, biogeography, and intrafamilial and intrapatient coincidence. The identification of shared susceptibility loci and DNA polymorphisms has confirmed this correlation at a genetic level. The pathogenesis of both diseases implicates the innate and adaptive segments of the immune system. Increased permeability of the epidermal barrier in skin and intestine underlies the augmented interaction of allergens and pathogens with inflammatory receptors of immune cells. The immune response between psoriasis and IBD is similar and comprises phagocytic, dendritic, and natural killer cell, along with a milieu of cytokines and antimicrobial peptides that stimulate T-cells. The interplay between dendritic cells and Th17 cells appears to be the core dysregulated immune pathway in all these conditions. The distinct similarities in the pathogenesis are also reflected in the wide overlapping of their therapeutic approaches. Small-molecule pharmacologic immunomodulators have been applied, and more recently, biologic treatments that target proinflammatory interleukins have been introduced or are currently being evaluated. However, the fact that some treatments are quite selective for either skin or gut conditions also highlights their crucial pathophysiologic differences. In the present review, a comprehensive comparison of risk factors, pathogenesis links, and therapeutic strategies for psoriasis and IBD is presented. Specific emphasis is placed on the role of the immune cell species and inflammatory mediators participating in the pathogenesis of these diseases.

Abstract
Topical drug therapies are commonly used to manage dermatologic diseases and their manifestations in the skin, hair, nails, and mucous membranes. Compared with systemic treatment, topical drug delivery provides 2 notable benefits in the management of skin diseases. In addition to delivering the active drug, a well-designed vehicle can have supportive effects on the skin, whereas a poorly designed vehicle can have detrimental effects. In many cases, the same active drug is available in several dosage forms, offering the prescriber the ability to tailor treatment to the patient's unique presentation and needs.

Abstract
All skin diseases have an underlying immune component. Owing to differences in animal and human immunology, the majority of drugs fail in the preclinical or clinical testing phases. Therefore animal alternative methods that incorporate human immunology into in vitro skin disease models are required to move the field forward. This review summarizes the progress, using examples from fibrosis, autoimmune diseases, psoriasis, cancer and contact allergy. The emphasis is on co-cultures and 3D organotypic models. Our conclusion is that current models are inadequate and future developments with immune-competent skin-on-chip models based on induced pluripotent stem cells could provide a next generation of skin models for drug discovery and testing.

Abstract
Background Keratinocytes are the major cells in epidermis, providing barrier components such as cornified cells through the sophisticated differentiation process. In addition, keratinocytes exerts their role as the defense cells via activation of innate immunity. It has been known that pathogen-associated molecular patterns (PAMPs) including double-strand RNA and nucleotides can provoke inflammatory reaction in keratinocytes. Objective The aim of this study is to evaluate the effect of Ampelopsis japonica Makino extract (AE) on PAMPs-induced inflammatory reaction of keratinocytes. Methods The effects of AE were determined using poly (I:C)-induced inflammation and imiquimod-induced psoriasiform dermatitis models. Results In cultured keratinocytes, AE significantly inhibited poly(I:C)-induced expression of inflammatory cytokines, such as interleukin (IL)-1β, IL-6, IL-8 and tumor necrosis factor-α. AE significantly inhibited poly(I:C)-induced release of caspase-1 active form (p20), and down-regulated nuclear factor-κB signaling pathway. In imiquimod-induced psoriasiform dermatitis model, topical application of AE resulted in significant reduction of epidermal hyperplasia. Conclusion These results suggest that AE may be a potential candidate for the treatment of skin inflammation.

Abstract
BACKGROUND Psoriasis is a chronic, inflammatory autoimmune skin disease that affects 1-3% of the world's population. Most patients with psoriasis have plaque psoriasis or psoriasis vulgaris, characterized by thickened erythematous scaly plaques and presenting in a variety of forms with distinct characteristics. Psoriasis is associated with a decreased quality of life as well as with severe comorbidities. OBJECTIVES The aim of this spontaneous, retrospective observational clinical study was to evaluate the pharmacological activity of advanced treatment based on the use of UVA-1 laser therapy with or without the co-administration of low dose cytokines [interleukin (IL)-4, IL-10] and anti-IL-1 antibodies in patients affected by psoriasis vulgaris. RESULTS In this study the efficacy of UVA-1 phototherapy and, in parallel, the decisive (statistically relevant) boosting activity of low-dose cytokines in ameliorating the Psoriasis Area Severity Index (PASI) score were assessed. These results show the effectiveness of combined use of phototherapy and low-dose cytokines therapy, highlighting the fundamental role of anti-inflammatory cytokines (IL-4, IL-10, anti-IL-1 antibodies) in the treatment of psoriasis vulgaris. CONCLUSION Further studies are necessary to confirm these preliminary data.

From the morphological to the transcriptomic characterization of a compromised three-dimensional in vitro model mimicking atopic dermatitis. Br J Dermatol 2015; 173:1006-14.

Abstract
BACKGROUND Atopic dermatitis (AD) is a chronic inflammatory skin disease in which skin barrier function is disrupted. In this AD environment, proinflammatory cytokines are upregulated, promoting a vicious circle of inflammation. Although several three-dimensional in vitro models mimicking AD have been published, no study has presented a fully characterized and controlled model of AD-related inflammation. OBJECTIVES To develop and characterize, from the morphological to the molecular level, a compromised reconstructed epidermis (RE) mimicking AD-related inflammation in vitro. METHODS Normal human keratinocytes were used to generate RE, treated or not with an inflammatory cocktail (polyinosinic-polycytidylic acid, tumour necrosis factor-α, interleukin-4 and interleukin-13). RESULTS The inflammatory cocktail induces some modifications observed in patients with AD: (i) it leads to spongiosis; (ii) it alters early and terminal differentiation proteins; (iii) it increases thymic stromal lymphopoietin and interleukin-8 secretion by keratinocytes and (iv) it results in a specific gene expression pattern. CONCLUSIONS The inflammatory context contributes to the morphological, functional and transcriptomic changes observed in AD skin. As a result, this compromised RE model shares some characteristics with those found in AD skin and thus can be used as a relevant tool for screening formulations and drugs for the treatment of AD.
