Pentacyclic triterpene compounds from loquat leaves reduce skin inflammation and epidermal hyperplasia in psoriasis via inhibiting the Th17 cells. Mol Immunol 2021; 132:30-40. [PMID: 33540227 DOI: 10.1016/j.molimm.2021.01.019] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2020] [Revised: 12/25/2020] [Accepted: 01/18/2021] [Indexed: 02/07/2023]
Abstract
Psoriasis is a refractory inflammatory skin disease affecting 2 %-3 % of the world population, characterized by the infiltration and hyper-proliferation of inflammatory cells and aberrant differentiation of keratinocytes. Targeting the IL-23/ Th17 axis has been well recognized as a promising therapeutic strategy, as the IL-23/ Th17 signal plays a vital role in the pathology of psoriasis. Three pentacyclic triterpene compounds isolated from loquat leaves have been reported with significant inhibitory effects on RORγt transcription activity and Th17 cell differentiation, and excellent performance in preventing lupus nephritis pathogenesis. However, the potential effects of these pentacyclic triterpene compounds on psoriasis remain unknown. In this study, we demonstrated the potent therapeutic effects of these pentacyclic triterpene compounds on psoriasis. These three pentacyclic triterpene compounds significantly alleviated skin inflammation as well as aberrant keratinocyte proliferation in an imiquimod-induced mouse psoriasis model. These compounds also inhibited the infiltration of immune cells and the level of pro-inflammatory cytokine in the dermis, as well as the cells number and changed the cytokine profiling expression of Th17 cells. These compounds could reduce the amount of CD4+ and CD8+ T cells in local lymph node, but not in spleen, which is different from hydrocortisone, the positive control treatment. These results suggest better performance of these compounds than steroids on treating psoriasis with less side effects on the integrated immune system. In summary, our findings uncover the potent therapeutic effects of pentacyclic triterpene compounds on psoriasis, providing potential candidate compounds for drug development.

Abstract
OBJECTIVE We investigated newly diagnosed patients with endogenous CS for molecular changes in skin by biopsy before and a year after treatment of CS. PATIENTS AND METHODS 26 Patients with CS and 23 healthy controls were included. All the patients were evaluated before and a year after treatment. Skin biopsies were obtained from abdominal region before and a year after treatment in patients with CS and once from healthy volunteers. Total RNA was isolated from the skin biopsy samples and the real-time PCR system was used to determine the expression levels of 23 genes in the skin biopsy. RESULTS Skin expression levels of HAS 1, 2 and 3 mRNAs were lower and COL1A2, COL2A1, COL3A1 mRNAs were higher in patients with CS than in normal controls. MMP-9, TIMP-1 and elastin mRNA expression levels were similar in two groups. Skin IL-1β mRNA expression level was significantly higher in patients with CS. None of these parameters changed significantly 12 months after treatment. Patients with CS showed higher skin GH and HSD11B1 mRNA expressions and lower GHR and IGF-1R mRNA expression compared to control. Expression levels of IGF-1, GR and HSD11B2 mRNA were similar in two groups. None of these parameters changed significantly 12 months after treatment. CONCLUSION CS is associated with increased expression levels of skin COL1A2, COL2A1, COL3A1 mRNAs (which are correlated with increased expression level of skin GH mRNA). Decreased skin HAS may cause decreased synthesis of HA that contributes to thinning of skin in CS. Increased local inflammatory cytokine and HSD11B1 mRNAs may be related to the acne formation in CS. Treatment of CS was not able to reverse these changes and ongoing changes were detected after treatment.

Abstract
Glucocorticoids are major therapeutic agents highly used in the medical field. Topical glucocorticoids have biologic activities which make them useful in dermatology – anti-inflammatory, vasoconstrictive, immune suppressive and antiproliferative, in treating inflammatory skin disorders (allergic contact eczema, atopic hand eczema, nummular eczema, psoriasis vulgaris or toxic-irritative eczema). Unfortunately, the beneficial effects of topical glucocorticoids are shadowed by their potential for adverse effects – muscle or skin atrophy, striae distensae, rubeosis or acne. Skin atrophy is one of the most prevalent side-effects, with changes found in all skin compartments – marked hypoplasia, elasticity loss with tearing, increased fragility, telangiectasia, bruising, cutaneous transparency, or a dysfunctional skin barrier. The structure and function of the epidermis is altered even in the short-term topical glucocorticoid treatment; it affects stratum corneum components, subsequently affecting skin barrier integrity. The dermis is altered by directly inhibiting fibroblast proliferation, reducing mast cell numbers, and loss of support; there is depletion of mucopolysaccharides, elastin fibers, matrix metalloproteases and inhibition of collagen synthesis. Atrophogenic changes can be found also in hair follicles, sebaceous glands or dermal adipose tissue. Attention should be paid to topical glucocorticoid treatment prescription, to the beneficial/adverse effects ratio of the chosen agent, and studies should be oriented on the development of newer, innovative targeted (gene or receptor) therapies.

Abstract
Self-emulsifying lipids (SEL) were used as a stabilizer for the preparation of dexamethasone lipid nanoparticles by membrane emulsification employing Shirasu porous glass. The effect of process and formulation parameters on the size and polydispersity and dexamethasone solubility in lipids and its release from lipid nanoparticles were investigated. Lipid phase pressure (40-80 kPa), membrane pore-size (0.1 - 0.4 µm) and agitation speed (300 - 900 rpm) did not affect the size and polydispersity of SEL. However, the size was increased with increasing lipid content and fatty acid chain of the lipid. Sizes of < 250 nm were achieved from TEGO® care:Gelucire® blend and it increased to 487 nm by adding 20% w/w of hard fat. The highest solubility of dexamethasone was found in TEGO® care 450 (29 mg/g). Release from the lipid nano-dispersions was extended with no burst effect and the absolute release was increased with increasing lipid content.

Abstract
Chronic, non-healing wounds impose a great burden on patients, professionals and health care systems worldwide. Diabetes mellitus (DM) and obesity are globally highly prevalent metabolic disorders and increase the risk for developing chronic wounds. Glucocorticoids (GCs) are endogenous stress hormones that exert profound effects on inflammation and repair systems. 11-beta-hydroxysteroid dehydrogenase 1 (11β-HSD1) is the key enzyme which controls local GC availability in target tissues such as skin. Since treatment with GCs has detrimental side effects on skin integrity, causing atrophy and delayed wound healing, we asked whether the dysregulated expression of 11β-HSD1 and consequently local GC levels in skin contribute to delayed wound healing in obese, diabetic db/db mice. We found increased expression of 11β-HSD1 during disturbed wound healing and in the healthy skin of obese, diabetic db/db mice. Cell analysis revealed increased expression of 11β-HSD1 in fibroblasts, myeloid cells and dermal white adipose tissue from db/db mice, while expression in keratinocytes was unaffected. Among diabetes- and obesity-related factors, insulin and insulin-like growth factor 1 down-regulated 11β-HSD1 expression in fibroblasts and myeloid cells, while glucose, fatty acids, TNF-α and IL-1β did not affect it. Insulin exerted its inhibitory effect on 11β-HSD1 expression by activating PI3-kinase/Akt-signalling. Consequently, the inhibitory effect of insulin is attenuated in fibroblasts from insulin-resistant db/db mice. We conclude that insulin resistance in obesity and diabetes prevents the down-regulation of 11β-HSD1, leading to elevated endogenous GC levels in diabetic skin, which could contribute to impaired wound healing in patients with DM.

Abstract
In recent years, a number of active materials have been developed to provide anti-aging benefits for skin and, among them, peptides have been considered the most promising candidate due to their remarkable and long-lasting anti-wrinkle activity. Recent studies have begun to elucidate the relationship between the secretion of emotion-related hormones and skin aging. Kisspeptin, a neuropeptide encoded by the KISS1 gene, has gained attention in reproductive endocrinology since it stimulates the reproductive axis in the hypothalamus; however, the effects of Kisspeptin on skin have not been studied yet. In this study, we synthesized Kisspeptin-10 and Kisspeptin-E, which are biologically active fragments, to mimic the action of Kisspeptin. Next, we demonstrated the anti-aging effects of the Kisspeptin-mimicking fragments using UV-induced skin aging models, such as UV-induced human dermal fibroblasts (Hs68) and human skin explants. Kisspeptin-E suppressed UV-induced 11 beta-hydroxysteroid dehydrogenase type 1 (11β-HSD1) stimulation leading to a regulation of skin aging related genes, including type I procollagen, matrix metalloproteinases-1 (MMP-1), interleukin-6 (IL-6), and IL-8, and rescued the skin integrity. Taken together, these results suggest that Kisspeptin-E could be useful to improve UV-induced skin aging by modulating expression of stress related genes, such as 11β-HSD1.

Abstract
OBJECTIVE To observe the therapeutic effect of different doses of dihydroartemisinin (DHA) on atopic dermatitis (AD) in mice and explore the mechanism. METHODS Forty-two C57BL/6 mice were randomly divided into 7 groups (n=6), including a blank control group, a 2, 4-dinitrochlorobenzene (DNCB)-induced AD model group, a solvent-treated group, 3 DHA treatment groups treated with 25, 75, and 125 mg/kg DHA, and a dexamethasone treatment group. The counts of skin scratches were recorded and the lesion scores were evaluated on a daily basis. After 7 consecutive days of treatment, skin tissues were sampled from the lesions on the back and ear of the mice for pathological examination with HE staining, Masson staining and toluidine blue staining. RESULTS Treatment with 25, 75, and 125 mg/kg DHA and dexamethasone all alleviated AD symptoms of mice, reduced the severity scores of skin lesions, and ameliorated pathological changes of the skin tissue. DHA at 125 mg/kg produced the most obvious therapeutic effect and significantly alleviated mast cell infiltration in the lesions as compared with the other treatment groups (P < 0.05). CONCLUSIONS DHA is effective for the treatment of AD in mice with an optimal dose of 125 mg/kg. The therapeutic effect of DHA is achieved probably through regulation of local immunity by inhibiting mast cell infiltration in the lesions.

Abstract
BACKGROUND Topical corticosteroids are highly effective compounds that are now widely used in dermatology for the treatment of various autoimmune and inflammatory disorders. Many corticosteroids are misused for diverse indications such as pigmentation, acne, pruritus, fungal or bacterial infections, rashes, and numerous other conditions. These products contain various constituents, most of which have hazards or toxic elements. OBJECTIVE The aim is to raise awareness among individuals in the city of Basrah, Iraq about the uses and abuses of applying fake products to the face to inform the consumers about potential harmful adverse effects. METHODS This study was a prospective multi-center clinic questionnaire of a demographic that involved the outpatient dermatology departments at the Al-Basrah teaching hospital and the Abu Al-Khaseeb hospital as well as the private clinics of two dermatology specialists in Basrah. A total of 235 patients with facial dermatoses secondary to the application of topical corticosteroids and counterfeit products or, a mixed formulation, for cosmetic purposes were recruited. RESULTS Most enrolled patients were female with 10-20 years aged group. The majority applied these products due to friends or pharmacy encouragement. Motivations for the use of these products included: skin fairness, lightening, and general cosmetic. Interestingly, acne and erythema were common whilst, atrophy, dryness, telangiectasia, and hirsutism appear on long- term use only. CONCLUSION The abuse of counterfeit cosmetic products and topical corticosteroids is in progress and they have adverse health events. There are many causes behind the abuse but the lack of education, lack of restriction, profitable for sellers and low prices are the main.

Caffeoyl-Prolyl-Histidine Amide Inhibits Fyn and Alleviates Atopic Dermatitis-Like Phenotypes via Suppression of NF-κB Activation. Int J Mol Sci 2020; 21:ijms21197160.

Abstract
Caffeic acid (CA) is produced from a variety of plants and has diverse biological functions, including anti-inflammation activity. It has been recently demonstrated that caffeoyl-prolyl-histidine amide (CA-PH), which is CA conjugated with proline-histidine dipeptide, relieves atopic dermatitis (AD)-like phenotypes in mouse. In this study, we investigated the molecular mechanism underlying CA-PH-mediated alleviation of AD-like phenotypes using cell line and AD mouse models. We confirmed that CA-PH suppresses AD-like phenotypes, such as increased epidermal thickening, infiltration of mast cells, and dysregulated gene expression of cytokines. CA-PH suppressed up-regulation of cytokine expression through inhibition of nuclear translocation of NF-κB. Using a CA-PH affinity pull-down assay, we found that CA-PH binds to Fyn. In silico molecular docking and enzyme kinetic studies revealed that CA-PH binds to the ATP binding site and inhibits Fyn competitively with ATP. CA-PH further suppressed spleen tyrosine kinase (SYK)/inhibitor of nuclear factor kappa B kinase (IKK)/inhibitor of nuclear factor kappa B (IκB) signaling, which is required for nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) activation. In addition, chronic application of CA-PH, in contrast with that of glucocorticoids, did not induce up-regulation of regulated in development and DNA damage response 1 (REDD1), reduction of mammalian target of rapamycin (mTOR) signaling, or skin atrophy. Thus, our study suggests that CA-PH treatment may help to reduce skin inflammation via down-regulation of NF-κB activation, and Fyn may be a new therapeutic target of inflammatory skin diseases, such as AD.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Baccharis dracunculifolia (Asteraceae) is a commonly used plant in traditional medicine known as "alecrim-do-campo". Popularly it has been used as an immunostimulant, antibiotic, anti-inflammatory among other applications. So far, only a few studies have investigated the B. dracunculifolia anti-inflammatory effect and none has investigated the effectiveness of essential oil on skin diseases. AIM OF THE STUDY The study aimed at evaluating the topical anti-inflammatory activity of B. dracunculifolia essential oil (BdEO) in mice models of acute and chronic skin inflammation. MATERIALS AND METHODS BdEO was obtained from leaves and it was analyzed with Gas Chromatograph. Topical anti-inflammatory activity of BdEO (0.1, 0.3 and 1.0 mg/ear) was evaluated in Arachidonic Acid or TPA-induced acute and chronic skin inflammation in mice. Parameters such edema, cell migration and keratinocytes proliferation were evaluated. In addition, safety and a possible mechanism of action for BdEO essential oil were also investigated. RESULTS Our results indicate that mainly terpenoids compounds compose BdEO. In addition, topical treatment with BdEO inhibited inflammatory parameters in both acute and chronic models of skin inflammation. This protective effect was associated with reduced edema formation, smaller cellular influx into the inflamed tissue and reduction of keratinocytes hyperproliferation. Although BdEO appears to exert its anti-inflammatory effect through a corticosteroid pathway, no local or systemic side effects were observed. CONCLUSION Taken together, the present results showed that the essential oil obtained by hydrodistillation from B. dracunculifolia leaf samples exhibit remarkable topical anti-inflammatory properties. Therefore, our study demonstrated evidence for BdEO topical anti-inflammatory efficacy and safety, suggesting that it could be considered for developing of a new phytotherapeutic formulation as treatment for skin diseases.

Simultaneous determination the concentration change of ketoconazole and dexamethasone acetate: application to drug-drug interaction in human keratinocyte. J Pharm Biomed Anal 2020; 188:113396. [PMID: 32535269 DOI: 10.1016/j.jpba.2020.113396] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2020] [Revised: 05/20/2020] [Accepted: 05/25/2020] [Indexed: 02/03/2023]
Abstract
BACKGROUND The combination of ketoconazole and dexamethasone acetate is one of the commonly used treatments in dermatology regiment for skin inflammation accompanied by fungal infections. This interaction of ketoconazole and dexamethasone may make the drug much effective, decrease the adverse reaction or toxic effects. At present, there was no information about the interaction of these two external drugs. Therefore, it was necessary to build a model to measure the levels and evaluate the interaction of ketoconazole and dexamethasone acetate in skin cells. METHODS In our study, the determination methodology of ketoconazole and dexamethasone acetate in human keratinocyte (HaCaT cells) was established and the interaction of these two drugs in cells was explored. HaCaT cells were cultured in medium containing ketoconazole, then they were sequentially cultured with or without dexamethasone acetate treatment for another 1, 2, 4, 8 and 12 h. The samples were then harvested and the concentrations were quantified by enhanced BCA (the bicinchoninic acid) protein assay. Furthermore, the analytes in the cell suspension were also prepared and analyzed by LC-MS method. RESULTS As a result, ketoconazole and dexamethasone acetate were detected at the concentration range of 0.02 to 5 μg/mL and 0.2 to 100 μg/mL, respectively. The RSD (relative standard deviation) and RE (relative error) of precision and accuracy of the two analytes in the cell suspension were all less than 15 %. The matrix effect values variations were all less than 15%. The results showed that there was no significant difference in the concentration of ketoconazole with or without dexamethasone acetate treatment within 12 h. CONCLUSIONS A simple, sensitive and rapid LC-MS method which could quantify these two analytes in cells simultaneously was developed for the first time. The results of the concentration changes meant that no interaction occurred when dexamethasone sequentially administrated for 12 h after ketoconazole treatment. This method was successfully applied to establish the cell pharmacokinetics methodology and preliminary studied the metabolism of drug-drug interaction of ketoconazole and dexamethasone acetate.

Abstract
Glucocorticoids are widely used for therapy of hematologic malignancies. Unfortunately, chronic treatment with glucocorticoids commonly leads to adverse effects including skin and muscle atrophy and osteoporosis. We found recently that REDD1 (regulated in development and DNA damage 1) plays central role in steroid atrophy. Here, we tested whether REDD1 suppression makes glucocorticoid-based therapy of blood cancer safer. Unexpectedly, approximately 50% of top putative REDD1 inhibitors selected by bioinformatics screening of Library of Integrated Network-Based Cellular Signatures database (LINCS) were PI3K/Akt/mTOR inhibitors. We selected Wortmannin, LY294002, and AZD8055 for our studies and showed that they blocked basal and glucocorticoid-induced REDD1 expression. Moreover, all PI3K/mTOR/Akt inhibitors modified glucocorticoid receptor function shifting it toward therapeutically important transrepression. PI3K/Akt/mTOR inhibitors enhanced anti-lymphoma effects of Dexamethasone in vitro and in vivo, in lymphoma xenograft model. The therapeutic effects of PI3K inhibitor+Dexamethasone combinations ranged from cooperative to synergistic, especially in case of LY294002 and Rapamycin, used as a previously characterized reference REDD1 inhibitor. We found that coadministration of LY294002 or Rapamycin with Dexamethasone protected skin against Dexamethasone-induced atrophy, and normalized RANKL/OPG ratio indicating a reduction of Dexamethasone-induced osteoporosis. Together, our results provide foundation for further development of safer and more effective glucocorticoid-based combination therapy of hematologic malignancies using PI3K/Akt/mTOR inhibitors.

Abstract
Topical hormone therapy with natural or synthetic ligands of nuclear hormone receptors such as glucocorticoids, vitamin D analogues and retinoids has a long and highly successful tradition in dermatology. Yet the dermatological potential of thyroid hormone receptor (TR) agonists has been widely ignored, despite abundant clinical, cell and molecular biology, mouse in vivo, and human skin and hair follicle organ culture data documenting a role of TR-mediated signalling in skin physiology and pathology. Here, we review this evidence, with emphasis on wound healing and hair growth, and specifically highlight the therapeutic potential of repurposing topical L-thyroxine (T4) for selected applications in future dermatological therapy. We underscore the known systemic safety and efficacy profile of T4 in clinical medicine, and the well-documented impact of thyroid hormones on, for example, human epidermal and hair follicle physiology, hair follicle epithelial stem cells and pigmentation, keratin expression, mitochondrial energy metabolism and wound healing. On this background, we argue that short-term topical T4 treatment deserves careful further preclinical and clinical exploration for repurposing as a low-cost, effective and widely available dermatotherapeutic, namely in the management of skin ulcers and telogen effluvium, and that its predictable adverse effects are well-manageable.

Abstract
AbstractA rapid and specific method was developed for simultaneous quantification of hydrocortisone 21 acetate (HCA), dexamethasone (DEX), and fluocinolone acetonide (FCA) in whitening cream formulations using reversed-phase high-performance liquid chromatography. The effect of the composition of the mobile phase, analysis temperature, and detection wavelength was investigated to optimize the separation of studied components. The analytes were finally well separated using ACE Excel 2, C18 AR column having 150 mm length, 3 mm internal diameter, and 2 µm particle size at 35°C using methanol with 1% formic acid and double-distilled deionized water in the ratio of 60:40 (v/v), respectively, as the mobile phase in isocratic mode. Ten microliters of sample were injected with a flow rate of 0.5 mL/min. The specificity, linearity, accuracy, precision, recovery, limit of detection (LOD), limit of quantification (LOQ), and robustness were determined to validate the method as per International Conference on Harmonization guidelines. All the analytes were simultaneously separated within 8 min, and observed retention times of HCA, DEX, and FCA were 4.5, 5.5, and 6.9 min, respectively. The proposed method showed good linearity with the correlation coefficient, R2 = 0.999 over the range of 1–150 µg/mL for all standards. The linear regression equations were y = 12.7x + 118.7 (r = 0.999) for HCA, y = 12.9x + 106.8 (r = 0.999) for DEX, and y = 12.9x + 96.8 (r = 0.999) for FCA. The LOD was 0.25, 0.20, and 0.08 µg/mL for HCA, FCA, and DEX and LOQ was 2.06, 1.83, and 1.55 µg/mL for HCA, FCA, and DEX, respectively. The recovery values of HCA, DEX, and FCA ranged from 100.7–101.3, 102.0–102.6, and 100.2–102.0%, respectively, and the relative standard deviation for precision (intra- and interday) was less than 2, which indicated repeatability and reproducibility. The novelty of the method was described by forced degradation experimentation of all analytes in the combined form under acidic, basic, oxidative, and thermal stress. The proposed method was found to be simple, rapid, and reliable for the simultaneous determination of HCA, DEX, and FCA in cosmetics.

Abstract
The fetal membranes are equipped with high capacity of cortisol regeneration through the reductase activity of 11β-hydroxysteroid dehydrogenase 1 (11β-HSD1). The expression of 11β-HSD1 in the fetal membranes is under the feedforward induction by cortisol, which is potentiated by proinflammatory cytokines. As a result, the abundance of 11β-HSD1 increases with gestational age and furthermore at parturition with an escalation of cortisol concentration in the fetal membranes. Accumulated cortisol takes parts in a number of crucial events pertinent to the onset of labor in the fetal membranes, including extracellular matrix (ECM) remodeling and stimulation of prostaglandin output. Cortisol remodels the ECM through multiple approaches including induction of collagen I, III, and IV degradation, as well as inhibition of their cross-linking. These effects of cortisol are executed through activation of the autophagy, proteasome, and matrix metalloprotease 7 pathways, as well as inhibition of the expression of cross-linking enzyme lysyl oxidase in mesenchymal cells of the membranes. With regard to prostaglandin output, cortisol not only increases prostaglandin E2 and F2α syntheses through induction of their synthesizing enzymes such as cytosolic phospholipase A2, cyclooxygenase 2, and carbonyl reductase 1 in the amnion, but also decreases their degradation through inhibition of their metabolizing enzyme 15-hydroxyprostaglandin dehydrogenase in the chorion. Taking all together, data accumulated so far denote that the feedforward cortisol regeneration by 11β-HSD1 in the fetal membranes is a requisite event in the onset of parturition, and the effects of cortisol on prostaglandin synthesis and ECM remodeling may be enhanced by proinflammatory cytokines in chorioamnionitis.

Abstract
Glucocorticoid hormones are vital; their accurate operation is a necessity at all ages and in all life situations. Glucocorticoids regulate diverse physiological processes and they use many signaling pathways to fulfill their effect. As the operation of these hormones affects many organs, the excess of glucocorticoids is actually detrimental to the whole human body. The endogenous glucocorticoid excess is a relatively rare condition, but a significant proportion of adult people uses glucocorticoid medication for the treatment of chronic illnesses, therefore they are exposed to the side effects of long-term glucocorticoid treatment. Our review summarizes the adverse effects of glucocorticoid excess affecting bones, adipose tissue, brain and skin, focusing on those effects which involve the Wnt/β-catenin pathway.

Abstract
Topical glucocorticoids, well-known anti-inflammatory drugs, induce multiple adverse effects, including skin atrophy. The sex-specific effects of systemic glucocorticoids are known, but sexual dimorphism of therapeutic and side effects of topical steroids has not been studied. We report here that female and male mice were equally sensitive to the anti-inflammatory effect of glucocorticoid fluocinolone acetonide (FA) in ear edema test. At the same time, females were more sensitive to FA-induced skin atrophy. We recently reported that REDD1 (regulated in development and DNA damage 1) plays central role in steroid atrophy. We found that REDD1 was more efficiently activated by FA in females, and that REDD1 knockout significantly protected female but not male mice from skin atrophy. Studies using human keratinocytes revealed that both estradiol and FA induced REDD1 mRNA/protein expression, and cooperated when they were combined at low doses. Chromatin immunoprecipitation analysis confirmed that REDD1 is an estrogen receptor (ER) target gene with multiple estrogen response elements in its promoter. Moreover, experiments with GR and ER inhibitors suggested that REDD1 induction by these hormones was interdependent on functional activity of both receptors. Overall, our results are important for the development of safer GR-targeted therapies suited for female and male dermatological patients.

Abstract
Corticosteroid-induced skin atrophy (CISA) consists of a thinning of the skin and subcutaneous tissues, representing the natural consequence of a prolonged glucocorticosteroids use, both systemic as well as topical. It is characterised by the loss of elasticity and skin thickness, associated with an increased skin fragility leading to ecchymoses, haematomas, and steroid purpura. The management of CISA is a challenge for physicians, as the pathology is reversible in a minimal percentage of cases and only after a short topical steroid or low-dose course therapy. Often wounds with large loss of substance represent the more common complication, after a surgical drainage which is often necessary. Skin necrosis with compartment syndrome of a leg is another potential risk for these patients. Here, we report a case of an elderly patient affected by multiple subcutaneous haematomas of the legs causing skin necrosis, arisen after the use of anticoagulants for a deep venous thrombosis. The patient was successfully treated with surgical drainage, negative pressure wound therapy (NPWT), and porcine xenograft with no complications. Finally, we discuss the evidence of the current literature on topic.

Abstract
Large tissue damage or wounds cause serious comorbidities and represent a major burden for patients, families, and health systems. Due to the pivotal role of immune cells in the proper resolution of inflammation and tissue repair, we focus our current study on the interaction of macrophages with skin cells, and specifically on the effects of CD163 gene induction in macrophages in wound healing. We hypothesize that the over-expression of the scavenger receptor gene CD163 in human macrophages would result in a more efficient wound healing process. Using 3D human wounded skin organotypic tissues, we observed that CD163 overexpression in THP-1 and human primary macrophages induced a more efficient re-epithelization when compared to control cells. Using human primary skin cells and an in vitro scratch assay we observed that CD163 overexpression in THP-1 macrophages promoted a more rapid and efficient wound healing process through a unique interaction with fibroblasts. The addition of CD163-blocking antibody, but not isotype control, blocked the efficient wound healing process induced by CD163 overexpression in macrophages. We found that the co-culture of skin cells and CD163 overexpressing macrophages reduced monocyte chemoattractant protein (MCP)-1 and enhanced tumor growth factor (TGF)-α, without altering interleukin (IL)-6 or TGF-β. Our findings show that CD163 induces a more efficient wound healing and seems to promote a wound milieu with a pro-resolution molecular profile. Our studies set the foundation to study this approach in in vivo clinically relevant settings to test its effects in wound healing processes such as acute major injuries, large surgeries, or chronic ulcers.

Abstract
We propose an elastic net made of a biocompatible polymer to wrap silicone implants of various sizes, which also allows for the sustained release of an anti-inflammatory drug, triamcinolone, to prevent fibrosis. For this, we first prepared a strand composed of a mixture of polyurethane and triamcinolone via electrospinning, which was then assembled to prepare the elastic drug-delivery net (DDN). The DDN was prepared to just fit for wrapping the small silicone implant sample herein, but was also able to wrap a sample 7 times as large at 72% strain due to the elastic property of polyurethane. The DDN exhibited sustained drug release for 4 weeks, the profile of which was not very different between the intact and strained DDNs. When implanted in a subcutaneous pocket in living rats, the DDN-wrapped silicone implant samples showed an obvious antifibrotic effect due to the sustained release of triamcinolone. Importantly, this effect was similar for the small and large silicone samples, both wrapped with the same DDN. Therefore, we conclude that this drug-loaded net made of an elastic, biocompatible polymer has high potential for sustained drug delivery around silicone implants manufactured in various sizes.

Abstract
Dexamethasone (DE) is a synthetic glucocorticoid that is frequently added to cosmetic products for its good short-term effects, especially in facial masks, but long-term use is hazardous to the health. The abuse of DE in whitening and acne cosmetic products is currently a serious problem in China. It is necessary to establish a rapid method of detecting illegal DE addition in cosmetics. In the present study, a monoclonal antibody (mAb) against DE, 2D5-3D12, was developed that displayed cross-reactivities of 124.5%, 38.8%, 6.7%, 0.9%, 1.1%, 1.82%, and 2.39% with prednisolone, betamethasone, prednisone, beclomethasone, hydrocortisone, triamcinolone, and flumetasone, respectively. A colloidal gold-based lateral flow immunographic assay based on mAb 2D5-3D12 was established and used to determine the DE contents of commercial facial masks. The indicator range of the immunographic assay for DE was 100-200 ng/mL, and the results were consistent with those afforded by LC-MS. This novel method provides the advantages of simple sample treatment, a user-friendly procedure, and rapid detection. Graphical abstract.

Abstract
In this work, magnetic metal-organic frameworks-101 functionalized with graphite-like carbon nitride material (Fe3O4/g-C3N4/MIL-101) has been simply prepared for the efficient enrichment of glucocorticoids in cosmetics. Due to the introduction of g-C3N4, the water stability of MIL-101 has been greatly improved. This composite material also showed better selectivity for glucocorticoids than those for polycyclic aromatic hydrocarbons and benzene compounds due to the hydrogen bonding effect with g-C3N4 and the size-matching effect with MIL-101. When the prepared material was used as the sorbents in magnetic solid-phase extraction (MSPE) and coupled with ultra-performance liquid chromatography-mass spectrometry (UPLC-MS/MS), a sensitive MSPE-UPLC-MS/MS method was developed. Under the optimal conditions, the calibration curves were linear over the concentration ranging from 0.01 to 2 μg/L with correlation coefficients (R2) between 0.9915 and 0.9995. The limit of detection (LOD) was as low as 2 ng/L with the RSDs lower than 5.5%. The recoveries ranged from 77.3% to 113%. The LOD of glucocorticoids in real samples analysis was improved by nearly three orders of magnitude compared to current literature records. The results indicated that Fe3O4/g-C3N4/MIL-101 could be used as MSPE extractant to determine glucocorticoids in complex cosmetics matrix.

Abstract
Seventy years after the discovery of their anti-inflammatory properties, glucocorticoids (GCs) remain the mainstay treatment for major allergic and inflammatory disorders, such as atopic dermatitis, asthma, rheumatoid arthritis, colitis, and conjunctivitis, among others. However, their long-term therapeutical administration is limited by major debilitating side effects, e.g., skin atrophy, osteoporosis, Addison-like adrenal insufficiency, fatty liver, and type 2 diabetes syndrome, as well as growth inhibition in children. These undesirable side effects are mostly related to GC-induced activation of both the direct transactivation and the direct transrepression functions of the GC receptor (GR), whereas the activation of its GC-induced indirect tethered transrepression function results in beneficial anti-inflammatory effects. We have reported in the accompanying paper that the nonsteroidal compound CpdX as well as its deuterated form CpdX-D3 selectively activate the GR indirect transrepression function and are as effective as synthetic GCs at repressing inflammations generated in several mouse models of major pathologies. We now demonstrate that these CpdX compounds are bona fide selective GC receptor agonistic modulators (SEGRAMs) as none of the known GC-induced debilitating side effects were observed in the mouse upon 3-mo CpdX treatments. We notably report that, unlike that of GCs, the administration of CpdX to ovariectomized (OVX) mice does not induce a fatty liver nor type 2 diabetes, which indicates that CpdX could be used in postmenopausal women as an efficient "harmless" GC substitute.

PI3K inhibitors protect against glucocorticoid-induced skin atrophy. EBioMedicine 2019; 41:526-537.

Abstract
Background Skin atrophy is a major adverse effect of topical glucocorticoids. We recently reported that REDD1 (regulated in development and DNA damage 1) and FKBP51 (FK506 binding protein 5), negative regulators of mTOR/Akt signaling, are induced by glucocorticoids in mouse and human skin and are central drivers of steroid skin atrophy. Thus, we hypothesized that REDD1/FKBP51 inhibitors could protect skin against catabolic effects of glucocorticoids. Methods Using drug repurposing approach, we screened LINCS library (http://lincsproject.org/LINCS/) to identify repressors of REDD1/FKBP51 expression. Candidate compounds were tested for their ability to inhibit glucocorticoid-induced REDD1/FKBP51 expression in human primary/immortalized keratinocytes and in mouse skin. Reporter gene expression, microarray, and chromatin immunoprecipitation were employed to evaluate effect of these inhibitors on the glucocorticoid receptor (GR) signaling. Findings Bioinformatics analysis unexpectedly identified phosphoinositide-3-kinase (PI3K)/mTOR/Akt inhibitors as a pharmacological class of REDD1/FKBP51 repressors. Selected PI3K/mTOR/Akt inhibitors-Wortmannin (WM), LY294002, AZD8055, and two others indeed blocked REDD1/FKBP51expression in human keratinocytes. PI3K/mTOR/Akt inhibitors also modified global effect of glucocorticoids on trascriptome, shifting it towards therapeutically important transrepression; negatively impacted GR phosphorylation; nuclear translocation; and GR loading on REDD1/FKBP51 gene promoters. Further, topical application of LY294002 together with glucocorticoid fluocinolone acetonide (FA) protected mice against FA-induced proliferative block and skin atrophy but did not alter the anti-inflammatory activity of FA in ear edema test. Interpretation Our results built a strong foundation for development of safer GR-targeted therapies for inflammatory skin diseases using combination of glucocorticoids with PI3K/mTOR/Akt inhibitors.

Abstract
The purpose of this study was to propose a standard for differentiation between normal dogs and patients with hyperadrenocorticism (HAC) by measuring skin thickness via ultrasonography in small breed dogs. Significant changes in skin thickness of patients treated with prednisolone (PDS) or patients with HAC treated with trilostane were evaluated. Skin thickness was retrospectively measured on three abdominal digital images obtained from small breed dogs weighing < 15 kg that underwent abdominal ultrasonography. Mean skin thickness of normal dogs was 1.03 ± 0.25 mm (mean ± SD). Both the HAC and PDS groups showed significantly thinner skin than that in the normal group. Seven of the 10 HAC patients treated with trilostane had increased skin thickness. The area under the curve value of 0.807 was based on the receiver operating characteristics (ROC) curve for differentiating normal dogs from HAC patients. Sensitivity was 76% and specificity was 73% when skin thickness was less than the 0.83 mm cutoff value. In conclusion, measurement of skin thickness in small breed dogs by using ultrasonography is likely to provide clinical information useful in differentiating HAC patients from normal dogs. However, exposure to PDS, trilostane, and other conditions may have a significant effect on skin thickness.

Abstract
We assessed the efficacy of ketorolac trometamol injections compared with triamcinolone acetonide injections in trigger digits. Patients with trigger digits were randomized to receive either ketorolac or triamcinolone. They were followed up at 3, 6, 12 and 24 weeks, and monitored for resolution of triggering, pain and total active motion. One hundred and twenty-one patients with single trigger digits were recruited (59 ketorolac, 62 triamcinolone). At 6 weeks, 54% of patients in the triamcinolone group had complete resolution of trigger, whereas no patients in the ketorolac group had resolution. At 12 weeks, 58% of patients in the triamcinolone group had complete resolution of trigger compared with 6.7% in the ketorolac group. At 24 weeks, both groups had comparable rates of resolution at 26% and 25%, respectively. Patients in the triamcinolone group had significantly better resolution of pain at 3, 6 and 12 weeks. But at 24 weeks, there was no significant difference in pain between both groups. Significantly less flexion deformity was reported at 3 weeks and 6 weeks in the triamcinolone group. In the short term, ketorolac was less effective in relieving symptoms of trigger digit than triamcinolone. Level of evidence: I.

Abstract
Myrtus communis is an important plant in the treatment of many different diseases. The aim of this review was to determine the importance of M. communis essential oil in the treatment of hemorrhoids. For preparing this manuscript, the information was extracted from different resources. The results of clinical studies showed that M. communis essential oil (lotion or ointment) can significantly improve bleeding, permanent pain, pain during defecation, anal irritation, anal itching and anal heaviness in patients with hemorrhoids types I and II. M. communis was also effective in treating patients who did not respond to current chemical treatments (anti-hemorrhoids ointment). Further clinical studies should look into designing a suppository form of M. communis essential oil and compare its effect with the lotion and ointment forms.

Abstract
FKBP51 (FK506-binding protein 51) is a known co-chaperone and regulator of the glucocorticoid receptor (GR), which usually attenuates its activity. FKBP51 is one of the major GR target genes in skin, but its role in clinical effects of glucocorticoids is not known. Here, we used FKBP51 knockout (KO) mice to determine FKBP51's role in the major adverse effect of topical glucocorticoids, skin atrophy. Unexpectedly, we found that all skin compartments (epidermis, dermis, dermal adipose and CD34+ stem cells) in FKBP51 KO animals were much more resistant to glucocorticoid-induced hypoplasia. Furthermore, despite the absence of inhibitory FKBP51, the basal level of expression and glucocorticoid activation of GR target genes were not increased in FKBP51 KO skin or CRISPR/Cas9-edited FKBP51 KO HaCaT human keratinocytes. FKBP51 is known to negatively regulate Akt and mTOR. We found a significant increase in AktSer473 and mTORSer2448 phosphorylation and downstream pro-growth signaling in FKBP51-deficient keratinocytes in vivo and in vitro. As Akt/mTOR-GR crosstalk is usually negative in skin, our results suggest that Akt/mTOR activation could be responsible for the lack of increased GR function and resistance of FKBP51 KO mice to the steroid-induced skin atrophy.

Inhibitory Effects of Prunella vulgaris L. Extract on 11 β-HSD1 in Human Skin Cells. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2018; 2018:1762478.

Abstract
Glucocorticoids are a risk factor for age-induced skin structure and function defects, and the glucocorticoid-activating enzyme, 11β-hydroxysteroid dehydrogenase 1 (11β-HSD1), represents a promising therapeutic target. Prunella vulgaris L. (PV) is a perennial and an edible herbaceous plant normally cultivated in Asia and Europe. A recent study demonstrated a broad range of biological activities of PV including immune modulatory, antiviral, antiallergic, anti-inflammatory, antioxidant, and antidiabetic. However, little is known about the inhibitory effect of PV on 11β-HSD1. In this study, we investigated the inhibitory effect of Prunella vulgaris L. extract (PVE) and the underlying mechanism of 11β-HSD11 inhibition. Consistent with these results, cortisol levels were also reduced by PVE in vitro. The cortisone-induced translocation of glucocorticoids receptor (GR) was also attenuated. In addition, PVE inhibited a cortisone-mediated decrease in collagen content in skin. Collectively, these results suggest the beneficial effects of PVE in maintaining skin integrity.

Abstract
The enzyme 11β-HSD1 plays a crucial role in the tissue-specific regulation of cortisol levels and it has been associated with various diseases. Inhibition of 11β-HSD1 is an attractive intervention strategy and the discovery of novel selective 11β-HSD1 inhibitors is of high relevance. In this study, we identified and evaluated a new series of selective peptide 11β-HSD1 inhibitors with potential for skin care applications. This novel scaffold was designed with the aid of molecular modeling and two previously reported inhibitors. SAR optimization yielded highly active peptides (IC50 below 400 nM) that were inactive at 1 µM concentration against structurally related enzymes (11β-HSD2, 17β-HSD1 and 17β-HSD2). The best performing peptides inhibited the conversion of cortisone into cortisol in primary human keratinocytes and the most active compound, 5d, was further shown to reverse cortisone-induced collagen damage in human ex-vivo tissue.

Abstract
The aim of this volume is to encourage the use of systems-level methodologies to contribute to the improvement of human-health . We intend to motivate biomedical researchers to complement their current theoretical and empirical practice with up-to-date systems biology conceptual approaches. Our perspective is based on the deep understanding of the key biomolecular regulatory mechanisms that underlie health, as well as the emergence and progression of human-disease . We strongly believe that the contemporary systems biology perspective opens the door to the effective development of novel methodologies to the improvement of prevention . This requires a deeper and integrative understanding of the involved underlying systems-level mechanisms. In order to explain our proposal in a simple way, in this chapter we privilege the conceptual exposition of our chosen framework over formal considerations. The formal exposition of our proposal will be expanded and discussed later in the next chapters.

Abstract
The nuclear hormone receptor (NR) superfamily comprises approximately 50 evolutionarily conserved proteins that play major roles in gene regulation by prototypically acting as ligand-dependent transcription factors. Besides their central role in physiology, NRs have been largely used as therapeutic drug targets in many chronic inflammatory conditions and derivatives of their specific ligands, alone or in combination, are frequently prescribed for the treatment of skin diseases. In particular, glucocorticoids (GCs) are the most commonly used compounds for treating prevalent skin diseases such as psoriasis due to their anti-proliferative and anti-inflammatory actions. However, and despite their therapeutic efficacy, the long-term use of GCs is limited because of the cutaneous adverse effects including atrophy, delayed wound healing, and increased susceptibility to stress and infections. The GC receptor (GR/NR3C1) and the mineralocorticoid receptor (MR/NR3C2) are members of the NR subclass NR3C that are highly related, both structurally and functionally. While the GR is ubiquitously expressed and is almost exclusively activated by GCs; an MR has a more restricted tissue expression pattern and can bind GCs and the mineralocorticoid aldosterone with similar high affinity. As these receptors share 95% identity in their DNA binding domains; both can recognize the same hormone response elements; theoretically resulting in transcriptional regulation of the same target genes. However, a major mechanism for specific activation of GRs and/or MRs is at the pre-receptor level by modulating the local availability of active GCs. Furthermore, the selective interactions of each receptor with spatio-temporally regulated transcription factors and co-regulators are crucial for the final transcriptional outcome. While there are abundant genome wide studies identifying GR transcriptional targets in a variety of tissue and cell types; including keratinocytes; the data for MR is more limited thus far. Our group and others have studied the role of GRs and MRs in skin development and disease by generating and characterizing mouse and cellular models with gain- and loss-of-function for each receptor. Both NRs are required for skin barrier competence during mouse development and also play a role in adult skin homeostasis. Moreover, the combined loss of epidermal GRs and MRs caused a more severe skin phenotype relative to single knock-outs (KOs) in developing skin and in acute inflammation and psoriasis, indicating that these corticosteroid receptors play cooperative roles. Understanding GR- and MR-mediated signaling in skin should contribute to deciphering their tissue-specific relative roles and ultimately help to improve GC-based therapies.

Abstract
Human parturition is a complex process involving interactions between the myometrium and signals derived from the placenta, fetal membranes, and fetus. Signals originating from fetal membranes are crucial components that trigger parturition, which is clearly illustrated by the labor-initiating consequence of membrane rupture. It has been recognized for a long time that among fetal tissues in late gestation the fetal membranes possess the highest capacity for cortisol regeneration by 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1). However, the exact role of this unique feature remains a mystery. Accumulating evidence indicates that this extra-adrenal source of cortisol may serve as an upstream signal for critical events in human parturition, including enhanced prostaglandin and estrogen synthesis as well as extracellular matrix remodeling. This may explain why such high capacity for cortisol regeneration develops in human fetal membranes at late gestation. Therefore, inhibition of 11β-HSD1 may provide a potential therapeutic target for prevention of preterm birth. This review summarizes the current understanding of the functional role of cortisol regeneration by 11β-HSD1 in human fetal membranes.

Epidermal glucocorticoid and mineralocorticoid receptors act cooperatively to regulate epidermal development and counteract skin inflammation. Cell Death Dis 2018; 9:588.

Abstract
Endogenous and synthetic glucocorticoids (GCs) regulate epidermal development and combat skin inflammatory diseases. GC actions can be mediated through the GC receptor (GR) and/or the mineralocorticoid receptor (MR), highly homologous ligand-activated transcription factors. While the role of GR as a potent anti-inflammatory mediator is well known, that of MR is not as clear, nor is whether these receptors cooperate or antagonize each other in the epidermis. To address this, we generated mice with epidermal-specific loss of both receptors (double knockout, DKO), and analyzed the phenotypical and functional consequences relative to single KOs or controls (CO). At birth, DKO epidermis displayed a phenotype of defective differentiation and inflammation, which was more severe than in either single KO, featuring neutrophil-containing infiltrates, and gene dysregulation characteristic of human psoriatic lesions. This phenotype resolved spontaneously. However, in adulthood, single or combined loss of GC receptors increased susceptibility to inflammation and hyperproliferation triggered by phorbol ester which, different to CO, was not effectively counteracted by GC treatment. Also, DKOs were more susceptible to imiquimod-induced psoriasis than CO showing severe defective epidermal differentiation and microabcesses while single KOs showed an intermediate response. Immortalized DKO keratinocytes featured increased proliferation kinetics and reduced cell size, a unique phenotype relative to single KO cells. The lack of GR and MR in keratinocytes, individual or combined, caused constitutive increases in p38 and ERK activities, which were partially reversed upon reinsertion of receptors into DKO cells. DKO keratinocytes also displayed significant increases in AP-1 and NF-κB transcriptional activities, which were partially rescued by ERK and p38 inhibition, respectively. Reinsertion of GR and MR in DKO keratinocytes resulted in physical and cooperative functional interactions that restored the transcriptional response to GCs. In conclusion, our data have revealed that epidermal GR and MR act cooperatively to regulate epidermal development and counteract skin inflammation.

Abstract
Glucocorticoids have excellent therapeutic properties; however, they cause significant adverse atrophogenic effects. The mTORC1 inhibitor REDD1 has been recently identified as a key mediator of glucocorticoid-induced atrophy. We performed computational screening of a connectivity map database to identify putative REDD1 inhibitors. The top selected candidates included rapamycin, which was unexpected because it inhibits pro-proliferative mTOR signaling. Indeed, rapamycin inhibited REDD1 induction by glucocorticoids dexamethasone, clobetasol propionate, and fluocinolone acetonide in keratinocytes, lymphoid cells, and mouse skin. We also showed blunting of glucocorticoid-induced REDD1 induction by either catalytic inhibitor of mTORC1/2 (OSI-027) or genetic inhibition of mTORC1, highlighting role of mTOR in glucocorticoid receptor signaling. Moreover, rapamycin inhibited glucocorticoid receptor phosphorylation, nuclear translocation, and loading on glucocorticoid-responsive elements in REDD1 promoter. Using microarrays, we quantified a global effect of rapamycin on gene expression regulation by fluocinolone acetonide in human keratinocytes. Rapamycin inhibited activation of glucocorticoid receptor target genes yet enhanced the repression of pro-proliferative and proinflammatory genes. Remarkably, rapamycin protected skin against glucocorticoid-induced atrophy but had no effect on the glucocorticoid anti-inflammatory activity in different in vivo models, suggesting the clinical potential of combining rapamycin with glucocorticoids for the treatment of inflammatory diseases.

Abstract
Angina bullosa hemorrhagica (ABH) is an infrequent dermatosis characterized by acute onset of hemorrhagic bulla in the oral cavity. Clinical presentation of ABH may be quite worrisome, and clinicians often feel skeptical regarding their clinical diagnosis and lack confidence in managing this distinct entity. Indeed, ABH is a completely benign and self-limited disorder. The exact etiopathogenesis of ABH is still unknown. There have been reports in the literature addressing a central role for mechanical instability of the epithelial-connective tissue connection in the pathogenesis of ABH. Moreover, it has been claimed that long-term usage of inhaled glucocorticoids (GCs) is involved in the development of ABH, since most of the reported cases are asthmatic patients, who were treated with inhaled GCs, and GCs are well known for their degradative activities on collagen formation. Here, we describe a case with ABH, who had a drug history of inhaled GCs and nonsteroidal anti-inflammatory drugs (NSAIDs). We assume that our case not only supports the association of inhaled GCs with ABH but also suggests a possible role for NSAIDs in the pathogenesis of ABH.
