[PMID: 37673869 PMCID: PMC10482869 DOI: 10.1038/s41419-023-06094-3] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2023] [Revised: 08/08/2023] [Accepted: 08/21/2023] [Indexed: 09/08/2023]
Abstract
Gasdermin D (GSDMD)-mediated pyroptosis has a significant pro-inflammation characteristic due to dramatic secretion of pro-inflammatory substances. However, its role remains unclear in psoriasis as one chronic inflammatory skin disorder with high prevalence. We found that N-terminal GSDMD (N-GSDMD) was aberrantly expressed in epidermis of skin lesion in psoriasis patients and imiquimod-induced psoriasis-like dermatitis (IIPLD) mice. In epidermis of IIPLD mice and M5 (simulating psoriatic inflammatory challenge)-treated keratinocytes cultured in vitro, cleavage products of caspase-1, GSDMD and IL-1β were increased. M5-stimulated keratinocyte presented typical pyroptosis morphology accompanied with PI-staining. Gsdmd-/- keratinocytes could not present pyroptosis morphology while stimulated with M5. Electroporation of recombinant N-GSDMD could make the pyroptosis morphology reappear. In Gsdmd-/- mice or keratinocyte-specific Gsdmd conditional knockout mice, we observed the alleviation of psoriatic inflammation and epidermal aberrant expression of Ki-67 and differentiation markers (loricrin and keratin 5) after imiquimod stimulation. Transplanting skin tissue from control mice to Gsdmd-/- mice can evoke the response to imiquimod stimulation in the background of Gsdmd-/- mice (not limited in transplanting area). In M5-stimulated keratinocytes, disulfiram or GSDMD siRNA transfection can inhibit pyroptosis and eliminate disproportionate increases of Ki-67 and PI. We further validated that topically application of disulfiram (pyroptosis inhibitor) also alleviated IIPLD in mice. These findings indicate a novel mechanism that GSDMD-mediated keratinocyte pyroptosis facilitates hyperproliferation and aberrant differentiation induced by immune microenvironment in psoriatic skin inflammation, which contributes to pathogenesis of psoriasis. Our study provides an innovative insight that targeting pyroptosis can be considered as a therapeutic strategy against psoriasis.

Diosmin nanocrystal gel alleviates imiquimod-induced psoriasis in rats via modulating TLR7,8/NF-κB/micro RNA-31, AKT/mTOR/P70S6K milieu, and Tregs/Th17 balance. Inflammopharmacology 2023; 31:1341-1359.

Abstract
Diosmin is a flavonoid with promising anti-inflammatory and antioxidant properties. However, it has difficult physicochemical characteristics since its solubility demands a pH level of 12, which has an impact on the drug's bioavailability. The aim of this work is the development and characterization of diosmin nanocrystals using anti-solvent precipitation technique to be used for topical treatment of psoriasis. Results revealed that diosmin nanocrystals stabilized with hydroxypropyl methylcellulose (HPMC E15) in ratio (diosmin:polymer; 1:1) reached the desired particle size (276.9 ± 16.49 nm); provided promising colloidal properties and possessed high drug release profile. Additionally, in-vivo assessment was carried out to evaluate and compare the activities of diosmin nanocrystal gel using three different doses and diosmin powder gel in alleviating imiquimod-induced psoriasis in rats and investigating their possible anti-inflammatory mechanisms. Herein, 125 mg of 5% imiquimod cream (IMQ) was applied topically for 5 consecutive days on the shaved backs of rats to induce psoriasis. Diosmin nanocrystal gel especially in the highest dose used offered the best anti-inflammatory effect. This was confirmed by causing the most statistically significant reduction in the psoriasis area severity index (PASI) score and the serum inflammatory cytokines levels. Furthermore, it was capable of maintaining the balance between T helper (Th17) and T regulatory (Treg) cells. Moreover, it tackled TLR7/8/NF-κB, miRNA-31, AKT/mTOR/P70S6K and elevated the TNFAIP3/A20 (a negative regulator of NF-κB) expression in psoriatic skin tissues. This highlights the role of diosmin nanocrystal gel in tackling imiquimod-induced psoriasis in rats, and thus it could be a novel promising therapy for psoriasis.

Paeonol Protects against Methotrexate Hepatotoxicity by Repressing Oxidative Stress, Inflammation, and Apoptosis-The Role of Drug Efflux Transporters. Pharmaceuticals (Basel) 2022; 15:ph15101296. [PMID: 36297408 PMCID: PMC9611069 DOI: 10.3390/ph15101296] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2022] [Revised: 10/16/2022] [Accepted: 10/19/2022] [Indexed: 11/06/2022] Open
Abstract
Methotrexate (MTX) is an effective chemotherapeutic agent against a wide range of tumors and autoimmune diseases; however, hepatotoxicity limits its clinical use. Oxidative stress and inflammation have been implicated in the pathogenesis of MTX-induced hepatotoxicity. Paeonol is a natural phenolic compound reported for its antioxidant and anti-inflammatory properties. The current study aimed to investigate the protective effect of paeonol against MTX-induced hepatotoxicity in rats and various mechanisms that underlie this postulated effect. Paeonol was administered orally in a dose of 100 mg/kg, alone or along with MTX, for 10 days. Hepatotoxicity was induced via a single intraperitoneal dose of MTX (20 mg/kg) on day 5 of the experiment. Concomitant administration of paeonol with MTX significantly ameliorated distorted hepatic function and histological structure, restored hepatic oxidative stress parameters (MDA, NO, and SOD), and combated inflammatory response (iNOS and TNF-α). Additionally, paeonol enhanced cell proliferation and survival, evidenced by upregulating the proliferating cell nuclear antigen (PCNA) and suppressing apoptosis and the disposition of collagen fibers in rat livers treated with MTX. Importantly, paeonol upregulated the drug efflux transporters, namely P-glycoprotein (P-gp) and the multidrug resistance-associated protein 2 (Mrp-2) in MTX-treated rats. In conclusion, paeonol offered a potent protective effect against MTX-induced hepatotoxicity through suppressing oxidative stress, inflammation, fibrosis, and apoptosis pathways, along with P-gp and Mrp-2 upregulation.

Abstract
BACKGROUND Psoriasis is an immune-related disease with dermal inflammation and epidermal hyperplasia. Cornulin has a significant role in keratinocyte proliferation and stimulates inflammation in psoriasis. AIM OF THE WORK This work aims to evaluate Cornulin expression values in lesional and perilesional psoriatic skin compared with the control group's skin through immunohistochemistry. METHODS This case-control study included 30 cases with plaque psoriasis and another 30 as controls. Patient samples were collected, and immunohistochemical staining of Cornulin was conducted. RESULTS In the epidermis, there was a stepwise pattern of significant Cornulin overexpression in keratinocytes starting from controls (34.00 ± 23.65) to lesional (62.59 ± 23.93) passing through perilesional skin (36.52 ± 18.49) (p < 0.001). Moreover, there was also a stepwise pattern of the significance of Cornulin starting from 4 in controls (13.3% for both) to 28 lesional cases (93.3%) and 18 (60.0%) passing through 17 perilesional skin cases (56.7%) and 5 (16.7%) (p < 0.001 for both) for inflammatory cells and adnexa, respectively. A significant relationship between lesional epidermal Cornulin's strong intensity and a higher H-score and both hyperkeratosis and parakeratosis was found (p = 0.008 for both intensity and 0.028 for both H-scores). CONCLUSION Cornulin might be implicated in keratinocyte hyperproliferation and inflammation in plaque psoriasis and may be valuable as therapeutic target.

Abstract
Psoriasis is a chronic immune-mediated inflammatory skin disease, affects about 2% to 3% of the world population. Valosin-containing protein (VCP) is one of the newly discovered markers that is highly expressed in neoplasms and hyperproliferative lesions. This work aimed to study the role of VCP in psoriasis vulgaris by immunohistochemical study and correlate its expression with the available clinicopathologic data. This prospective case-control study was conducted on 25 patients with psoriasis vulgaris and 25 age-matched and sex-matched healthy individuals as a control group. Skin biopsies were taken under local anesthesia from cases and controls. VCP immunoreactivity showed that epidermal VCP expression had a significant stepwise increase (P=0.002) from control to lesional psoriatic sections. Epidermal VCP H-score was significantly associated with the progressive course (P=0.037). Similarly, VCP in the dermis showed a significant expression in lesional psoriatic skin (P≤0.001). Higher VCP in the dermis in cases with a history of joint affection (P<0.05) was detected. We concluded that VCP is a promising marker for follow-up and monitoring of psoriatic patients and may play a role as a therapeutic target.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Our clinical practice demonstrated that Jueyin granules (JYG) benefit patients with mild to moderate psoriasis vulgaris without apparent adverse effects. JYG have been shown to inhibit epidermal proliferation in an imiquimod (IMQ)-induced psoriasis-like mouse model, as well as keratinocyte proliferation. Moreover, JYG causes no acute or chronic toxicity in animal models. However, its related molecular mechanism has still not been elucidated. AIM OF THE STUDY To assess the mechanism of JYG against psoriasis. MATERIALS AND METHODS This study combined network pharmacology analysis with experiments to investigate the mechanism of JYG against psoriasis. First, the molecular docking technology was used to construct the network of medicinal materials-core active plant ingredients-core targets and identify possible drug targets. Next, high-performance liquid chromatography (HPLC) was used for quality control of JYG. Finally, a mice model of psoriasis was used to further verify the effects of JYG. RESULTS (1) Molecular docking analysis of network pharmacology revealed that the therapeutic effects of JYG on psoriasis might be achieved through Vitamin D Receptor (VDR) effects. (2) The concentrations of chlorogenic acid and paeoniflorin were determined using HPLC to establish quality control of JYG. (3) JYG ameliorated pathological characteristics that included in vivo reductions in erythema, scale, and infiltration scores of back and ear lesions in IMQ-induced psoriasis-like mice. Moreover, a reduced number of PCNA-positive and Ki67-positive cells were observed in the epidermis of JYG-treated lesions. JYG also reduced inflammation (interleukin (IL)-17, IL-23) in the peripheral blood of IMQ-induced psoriasis-like mice. As expected, JYG was found to upregulate VDR expression and downregulate p-STAT3 expression in the IMQ group, which may contribute to its mechanism against psoriasis. CONCLUSION Overall, this study clarifies the mechanism of JYG against psoriasis and provides evidence to support its clinical use.

Abstract
Abstract
Introduction. Psoriasis is a chronic inflammatory skin disease with hyperproliferation, abnormal differentiation and inflammatory infiltration in epidermis and dermis. Sometimes it is clinically and histopathologically challenging to distinguish psoriasis from other non-psoriatic psoriasiform dermatoses (NPPD) like eczema, pityriasis rosea, pityriasis rubra pilaris, and lichen simplex chronicus. Ki-67 is a non-histone nuclear protein complex that regulates the cell cycle and is the most widely used proliferation immunohistochemistry (IHC) marker. Its levels have been shown to be raised in psoriasis compared to normal skin.
Aim. To elucidate and compare expression of IHC Ki-67 in psoriasis and NPPD, correlate these levels with clinical variants and disease severity in psoriasis and to observe change in levels with demographic and psoriasis-related variables.
Material and Methods. Thirty patients, each with clinically diagnosed psoriasis (cases), and NPPD (controls) were enrolled. Biopsy was taken for histopathology and IHC Ki-67 immunohistochemistry. Statistical analysis was performed.
Results. We found a significantly higher expression of IHC Ki-67 in psoriasis as compared to all types of NPPD. The higher level of Ki-67 in pustular and erythrodermic psoriasis compared to plaque-type emphasizes the greater severity and activity of these forms. The Ki-67 expression was found to increase with increasing body surface area involvement and disease severity (PASI) in chronic plaque type. Pityriasis rubra pilaris had the highest Ki67 expression among NPPD group.
Conclusion. Ki-67 is a promising tool with diagnostic and prognostic utility in psoriasis, particularly when it comes to its differentiation from nonpsoriasis psoriasiform disorders.

Abstract
Many autoimmune disorders such as psoriasis lead to the alteration of skin components which generally manifests as unwanted topical symptoms. One of the most widely approved psoriasis-like animal models is the imiquimod (IMQ)-induced mouse model. This representation mimics various aspects of the complex cutaneous pathology and could be appropriate for testing topical treatment options. We perform a thorough characterization of this model by assessing some parameters that are not fully described in the literature, namely a precise description of skin disruption. It was evaluated by transepidermal water loss measurements and analyses of epidermis swelling as a consequence of keratinocyte hyperproliferation. The extent of neo-angiogenesis and hypervascularity in dermis were highlighted by immunostaining. Moreover, we investigated systemic inflammation through cytokines levels, spleen swelling and germinal centers appearance in draining lymph nodes. The severity of all parameters was correlated to IMQ concentration in skin samples. This study outlines new parameters of interest useful to assess this model. We highlight the skin barrier disruption and report a systemic inflammatory reaction occurring at distance both in spleen and lymph nodes. These newly identified biological endpoints could be exploited to investigate the efficacy of therapeutic candidates for psoriasis and more extensively for several other skin inflammatory diseases.

Abstract
Introduction Methotrexate and acitretin are known to be effective in the treatment of psoriasis, but the mechanisms of the effects of these drugs are not fully known. Aim To investigate the effect of methotrexate and acitretin on microvessel density (MVD) in psoriasis. Material and methods Eighteen patients with psoriasis treated with methotrexate and 9 patients with psoriasis treated with acitretin (AT) were included in this study. MVD was evaluated immunohistochemically by using CD31 and CD105 (endoglin) antibodies. Results In the methotrexate group, the decrease in CD31 levels after treatment was found to be statistically significant, while in the AT group it was found to be highly significant. In both methotrexate and AT group, there was a statistically highly significant decrease in CD105 levels after treatment. There was no statistically significant difference between CD31 measurements of methotrexate and AT groups. When CD105 levels were measured before and after treatment, no statistically significant difference was found between methotrexate and AT. According to the results of CD31 changes before and after treatment, the CD31 difference was not statistically significant in both groups while the difference was higher in the AT group. CD105 differences were not statistically significant in both treatment groups before and after treatment. Conclusions CD31 and CD105 dyes indicate the effects of therapies on vascular proliferation and may be indicators that can be used in daily routine and follow-up studies for psoriasis.

Evaluation of the expression of the stromal cell-derived factor-1 alpha (CXCL 12) in psoriatic patients after treatment with Methotrexate. J Cosmet Dermatol 2019; 19:253-258. [PMID: 31116013 DOI: 10.1111/jocd.12994] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2018] [Revised: 04/06/2019] [Accepted: 04/25/2019] [Indexed: 01/16/2023]
Abstract
BACKGROUND CXCL12 has an important role in skin homeostasis and inflammation. OBJECTIVE In this work, the expression of CXCL12 was evaluated in psoriasis vulgaris, psoriatic arthritis (PsA) patients in relation to disease activity and methotrexate (MTX) therapy. METHODS Skin biopsies were obtained from 10 psoriasis vulgaris patients, 10 PsA patients, and 20 controls. The biopsies were repeated 6 weeks after MTX therapy. The biopsies were stained immunohistochemically by stromal dermal factor 1 alpha (CXCL 12) antibody. RESULTS Psoriatic arthritis showed significantly more expression of CXCL 12 than psoriasis vulgaris patients before treatment but not after treatment. There was significant decrease in CXCL 12 expression in the keratinocytes of psoriasis vulgaris patients after MTX therapy than before treatment, P-value was 0.009. There was no significant difference between pre- and post-treatment in the CXCL 12 expression of keratinocytes of PsA patients, P-value was 0.093. The percentage decrease of PASI score after treatment showed a moderate correlation with the percentage decrease of CXCL12 expression of the keratinocytes of the total psoriasis patients, r = 0.484, P-value was 0.015. CONCLUSION CXCL12 might be involved in the progression of psoriasis vulgaris to PsA. MTX therapy downregulated the expression of CXCL12 of the keratinocytes of psoriasis patients. This downregulation was paralleled by decrease in the PASI score. CXCL12 can be used as a biological marker of disease severity of psoriasis patients.

Abstract
Matrix metalloproteinases (MMPs) are important for the pathogenesis of psoriasis and other autoimmune disorders. In the extracellular matrix, accumulation of proinflammatory cytokines, such as interleukin 17A (IL-17A), leads to induction of several MMPs, including MMP1. MMPs change the composition and other properties of the extracellular matrix. These changes facilitate tissue remodeling and promote the development of psoriatic plaques. The aim of this study was to explore how MMP1 silencing might influence the biological effects of IL-17A on migration and proliferation of human epidermal keratinocytes and the expression of genes involved in their division and differentiation. The experiments were performed with MMP1-deficient and control epidermal keratinocytes, HaCaT-MMP1 and HaCaT-KTR, respectively. Cell proliferation and migration were assessed by comparative analysis of the growth curves and scratch assay, respectively. To quantify cell migration, representative areas of cell cultures were photographed at the indicated time points and compared to each other. Changes in gene expression were analyzed by real-time PCR. The obtained results demonstrated that MMP1 silencing in the cells treated with IL-17A resulted in downregulation of MMP9 and -12, FOSL1, CCNA2, IVL, KRT14 and -17 as well as upregulation of MMP2, CCND1 and LOR. Moreover, MMP1 silencing led to a decrease in cell proliferation and an impairment of cell migration. Thus, MMP1-deficiency in epidermal keratinocytes can be beneficial for psoriasis patients that experience an accumulation of IL-17 in lesional skin. Knocking MMP1 down could influence migration and proliferation of epidermal keratinocytes in vivo, as well as help to control the expression of MMP1, -2, -9 и -12, CCNA2, CCND1, KRT14 and -17 that are crucial for the pathogenesis of psoriasis.

Abstract
Myelomeningocele (MMC) is a severe type of neural tube defect (NTD), in which the backbone and spinal canal do not close completely during early embryonic development. This condition results in serious morbidity and increased mortality after birth. Folic acid significantly reduces, and conversely, folate antagonist methotrexate (MTX) and valproic acid (VPA) increase the occurrence of NTDs, including MMC. How these pharmacological agents exactly influence the early neurulation process is still largely unclear. Here, we characterized human amniotic fluid-derived stem cells (AFSCs) from prenatally diagnosed MMC and observed an effect of MTX and VPA administration on the early neural differentiation process. We found that MMC-derived AFSCs highly expressed early neural and radial glial genes that were negatively affected by MTX and VPA exposure. In conclusion, we setup a human cell model of MMC to study early neurogenesis and for drug screening purposes. We also proposed the detection of early neural gene expression in AFSCs as an additional MMC diagnostic tool.

Abstract
Psoriasis is a chronic inflammatory skin disease characterized by hyper proliferation of keratinocytes. Recent data show that the epidermis thickening in psoriasis may be related to imbalance of homeostasis caused by abnormal apoptotic process. Maintenance of keratinocyte apoptotic process is very important in psoriasis. Methotrexate (MTX) has been used for many years to restore the normal skin in psoriasis condition. However, the exact mechanism of MTX in psoriasis condition is poorly understood. The aim of this study was to examine the role of MTX on keratinocyte apoptosis pathway in psoriasis patients. A total of 58 psoriasis vulgaris patients were recruited for this study. Nonlesional skin biopsies served as control. Skin biopsies of psoriatic patients were collected and analyzed for cytosolic, mitochondria and total cytochrome c by ELISA. Expression of caspase-9, NFκBp65, pAkt1 by western blot, real-time PCR and immunohistochemical analysis of c-FLIP protein was analyzed in nonlesional and lesional skin biopsies before (day 0) and after (at the end of 6 and 12 weeks) MTX treatment. After MTX treatment, a significant increase in cytochrome c was observed when compared with before MTX treatment in psoriasis patients (p < 0.001). Protein and gene expression of cleaved caspase-9 were significantly increased after MTX treatment, whereas the expression of Bcl-xL, c-FLIP, NFκBp65, pAkt1 significantly downregulated after MTX treatment. In conclusion, these results showed that intrinsic apoptotic pathway induced by MTX eventually adds the beneficial therapeutic role of MTX in psoriasis by controlling the acanthosis.

Abstract
Background: Differentiation of psoriasis from non-psoriasis psoriasiform dermatitis (NPPD) may be difficult for dermatopathologists, as lack of distinctive histopathological features in a subset of cases may cause confusion in diagnosis. Objective: As the prototype of psoriasiform dermatitis, psoriasis is a hyperproliferative skin disorder with increased epidermal turnover compared with NPPD, we investigated the role of proliferation markers, Ki-67 and Cyclin D1 as diagnostic tools to differentiate psoriasis from other psoriasiform dermatitis. Methods: Histopathological specimens of psoriasis (n = 35) and NPPD (n = 36, 14 pityriasis rubra pilaris, 12 pityriasis rosea and 10 lichen simplex) cases were reviewed and immunohistochemically stained for Ki-67 and Cyclin D1. Ki-67 and Cyclin D1 positive cells were counted for suprabasal, and total epidermal immunostaining per mm2. Results: Suprabasal and total epidermal cell counts for Ki-67 were found to be significantly higher in the psoriasis group compared with the NPPD group (p < 0.05). An important and interesting feature was the presence of a cut-off value for the suprabasal/total epidermal cell count ratio of 75% for Ki-67 immunostaining, which was higher in all patients having psoriasis (range, 77.1% – 92.4%) and lower in all NPPD cases (range, 21.0% – 73.3%). However, suprabasal Cyclin D1 cell counts were higher in the psoriasis group compared with the NPPD group (p < 0.05), total epidermal Cyclin D1 cell counts were not statistically significant in either group (p = 0.167), and a cut-off value for suprabasal/total epidermal cell count ratio to distinguish these two entities was not detected using this immunostain. Conclusions: We suggest that Ki-67 is a more sensitive marker than Cyclin D1 in terms of having a cutoff value of 75% for the suprabasal/total epidermal immunoreactive cell count ratio, which we believe could be useful for dermatopathologists in differentiating psoriasis from other psoriasiform dermatitis.

Abstract
Vascular endothelial growth factor (VEGF) is important factor for angiogenesis in psoriasis. Methotrexate and psoralen and ultraviolet light A (PUVA) mainly target the T cell-mediated immunopathology of psoriasis. Our work aimed at estimating VEGF mRNA in psoriatic patients and investigating whether the standard therapeutic modalities (methotrexate and PUVA) exert their antiangiogenic activity through altering VEGF levels. Twenty-four chronic plaque psoriasis patients were enrolled. Patients were divided into two groups (12 patients each); group A received intramuscular methotrexate and group B was treated by PUVA three times/week in a PUVA 1000 cabin for 10 weeks each. Twelve healthy volunteers served as controls. A skin biopsy was taken from lesional skin before and after treatment for RT-PCR detection of VEGF mRNA. Capillary perfusion scanning using LASER Doppler perfusion imaging was performed on the same psoriatic plaque before and after treatment and was also done for the controls. Following both methotrexate and PUVA, a significant reduction in the amount of VEGF mRNA (P < 0.001 and P = 0.002, respectively) and capillary perfusion (P = 0.002) occurred. These reductions were significantly higher in the methotrexate group (P < 0.001 and P = 0.001, respectively) than in the PUVA group. The percentage of clinical improvement in the examined psoriatic plaque was significantly positively correlated with the percentage of reduction in the amount of VEGF mRNA (r = 0.850, P < 0.001) and the percentage of reduction in the capillary perfusion (r = 0.684, P < 0.001). Both modalities may exert an antiangiogenic effect. Methotrexate appears to have possibly a more potent antiangiogenic effect than PUVA.

Abstract
Interleukin-1 plays a key role in inflammation and keratinocyte activation. It is an important mediator in the initiation and maintenance of psoriatic plaques and may represent an attractive therapeutic target. The aim of this study is to evaluate the effect of Methotrexate (MTX) on IL-1 α and IL-1 β levels in both plasma and skin biopsy of patients with psoriasis and to investigate their association with clinical disease activity. Forty-five control subjects and 58 patients with psoriasis were recruited for this study. The patients were treated with 7.5 mg of MTX per week for 12 weeks. Folic acid was given at 5 mg once daily except on the day of MTX for 12 weeks. Blood samples and lesional skin biopsy were taken. Disease severity was assessed by Psoriasis Area Severity Index (PASI) score. IL-1 levels in plasma and skin biopsy were analysed using ELISA. PASI score declined significantly (P < 0.001) from day 0 to 12 weeks of MTX treatment. IL-1 α level in plasma and skin biopsy was reduced at day 0 sample and elevated significantly (P < 0.001) after MTX treatment. IL-1β level in plasma and skin biopsy was higher at day 0 sample and reduced significantly (P < 0.001) after MTX treatment. IL-1α levels and PASI score showed inverse correlation score before and after treatment with MTX. Whereas IL-1β levels showed positive correlation before and after treatment with MTX. Decreasing IL-1β levels by MTXs in psoriasis may block the Th17 differentiation. This shows the therapeutic effect of MTX in controlling the immunopathogenesis of psoriasis.

Abstract
BACKGROUND Psoriasis is a chronic autoimmune hyperproliferative skin disease. In psoriasis, the cutaneous and systemic overexpression of various proinflammatory cytokines, such as interleukin-6 (IL-6) has been demonstrated. Methotrexate (MTX) has been used in the treatment of psoriasis. The aim of this study is to assess the effect of MTX on serum IL-6 levels and also to find the association between PASI score and IL-6 levels in psoriatic patients during MTX therapy. METHODS We recruited 20 control subjects and 22 Psoriasis vulgaris patients for this study. The patients were treated with 7.5mg of methotrexate per week for 12 weeks. Folic acid was given at 5mg once daily except on the day of MTX for 12 weeks. There were 2 dropouts, because of increased liver enzyme levels. Blood samples were collected at three intervals (i.e., Day 0, 6 weeks, 12 weeks) from psoriatic patients and only once from control subjects. PASI score, biochemical and hematological parameters were assessed. Serum IL-6 level was analyzed by using ELISA. RESULTS Biochemical and hematological parameters showed no significant changes. Serum IL-6 level and PASI score declined significantly (p<0.001) from Day 0 to 12 weeks of MTX treatment and also showed positive correlation before (r=0.992; p<0.000) and after (r=0.987; p<0.000) treatment with MTX. Out of 4 clinical indices of PASI, only 2 indices namely Infiltration (I) and Desquamation (D) showed positive correlation with IL-6 before and after MTX treatment. CONCLUSION The treatment response with MTX in psoriatic patients can be seen both at clinical and molecular levels.

Abstract
BACKGROUND Neutrophil elastase (NE) plays an important role in psoriasis. In this study we observed the effect of NE on the proliferation of HaCaT cells and transwell psoriasis organ culture model and investigated the mechanism. METHODS HaCaT cells were treated with various concentrations NE (0, 0.1, 1, 10, 100 IU/l). In addition, the cells were co-stimulated with 10 IU/l NE and 1 g/l sivelestat. Then, HaCaT cells proliferation and DNA synthesis were determined using methyl thiazolyl tetrazolium (MTT) and tritiated thymidine (3H-TdR) assay respectively. Cell cycle distribution was measured using fluorescence activated cell sorting (FACS). Subsequently, we established cultured transwell psoriasis organ model in vitro. Then, the cultured transwell psoriasis organ model was treated with 10 IU/l NE. Immunohistochemistry was employed to detect the expression levels of Ki67 and p53 in the cultured transwell psoriasis organ model. RESULTS MTT and 3H-TdR incorporation assay suggested NE could remarkably promote the proliferation and DNA synthesis of HaCaT cell in a dose-dependent manner. After NE treatment (10 IU/l) for 24 h, the cell fraction of HaCaT cell in G2 + S phase was increased significantly, whereas the cell fraction in G1 phase was reduced remarkably. Immunohistochemistry results revealed enhanced expression of both Ki67 and p53 genes in cultured transwell psoriasis organ model after NE treatment. CONCLUSIONS NE significantly promotes the proliferation of HaCaT cell. Meanwhile, it also up-regulates the expression levels of Ki67 and p53 in psoriasis lesion tissue, which plays an important role in the pathogenesis of psoriasis lesion.

Abstract
BACKGROUND Topical transdermal gene delivery to the skin shows great potential for painless, non-invasive administration of vaccines and therapeutic agents. Interleukin (IL)-4 strategies have shown a good antipsoriatic effect in clinic trials. To date, no information has been acquired on the effectiveness of gene therapy for psoriasis in the K14-VEGF transgenic mouse model by topical transdermal penetration of murine IL-4 (mIL-4) using ultradeformable cationic liposome (UCL). METHODS In the present study, we synthesized an UCL and determined a suitable formula for transdermally delivering plasmid DNA to mouse skin. We then tested the antipsoriatic efficacy in the K14-VEGF transgenic mouse model by transdermal delivery of mIL-4 using UCL. RESULTS We found that plasmid DNA was transdermally delivered to vicinal sites of epidermis and hair follicles using this optimized formula. Plasmid DNA expression was detected in ear skin. Twenty-four hours after topical application, plasmid DNA was not detected in blood serum and liver, which may decrease the risk of insertion of promoter from plasmid to genomic DNA. Mice treated with UCL/mIL-4 displayed a mild psoriasis phenotype. Histological analysis of pathological score using the Baker scoring system revealed an antipsoriatic effect. Immunohistochemical analysis revealed that hyperplastic and inflamed vessels were suppressed. CONCLUSIONS These observations provide evidence of antipsoriatic efficacy by topical transdermal delivery of mIL-4. Therefore, topical transdermal gene transfer is attractive and offers future potential for application in human patients with other dermatogic diseases.

Anti-psoriatic effects of indigo naturalis on the proliferation and differentiation of keratinocytes with indirubin as the active component. J Dermatol Sci 2009; 54:168-74. [PMID: 19303259 DOI: 10.1016/j.jdermsci.2009.02.007] [Citation(s) in RCA: 60] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2008] [Revised: 02/06/2009] [Accepted: 02/16/2009] [Indexed: 11/22/2022]
Abstract
BACKGROUND Indigo naturalis has shown efficacy in treating psoriasis in our previous clinical studies. OBJECTIVES To investigate the potential effect of indigo naturalis on regulating keratinocyte proliferation and differentiation. METHODS Skin samples from six patients were analyzed for proliferating cell nuclear antigen (PCNA) and involucrin expression by immunohistochemical staining. In addition, indigo naturalis extracts from 10 to 500 microg/ml were added to cultured keratinocytes and cell viability determined. Real-time RT-PCR, Western blotting analysis and indirect immunofluorescent labeling were used to investigate the messenger (m)RNA and protein expressions of PCNA and involucrin. Finally, high-performance liquid chromatography (HPLC) was used to identify major components of indigo naturalis and their in vitro effects compared. RESULTS Immunohistochemical results demonstrated decreased PCNA and increased involucrin in psoriatic lesions after indigo naturalis treatment. Cultured keratinocytes decreased after indigo naturalis treatment, while G(0)/G(1) arrest was observed to dose-dependently increase. Staining revealed decreased PCNA-stained nuclei and increased cytosolic involucrin in treated keratinocytes. Decreased PCNA and increased involucrin at both the mRNA and protein levels were confirmed. Both major components, indirubin and indigo, could cause G(0)/G(1) phase arrest; however, only indirubin modulated the expressions of PCNA and involucrin similar to indigo naturalis. CONCLUSIONS Together, these findings indicate that the anti-psoriatic effects of indigo naturalis are mediated, at least in part, by modulating the proliferation and differentiation of keratinocytes, with indirubin as the major active component.

Abstract
BACKGROUND The mechanism of the action of methotrexate (MTX) in the treatment of psoriasis has not been completely elucidated. OBJECTIVE To assess the effect of MTX on the expression of intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), E-selectin, activation molecule CD69 and T-cell phenotype in skin specimens from patients with psoriasis. METHODS We performed an immunohistochemical analysis of the expression of T-cell phenotype and cell adhesion/activation molecules in skin biopsies from patients with psoriasis treated with a fixed dose of MTX (12.5 mg/week). To determine data on the epidermal/dermal T-cell infiltration we carried out a manual quantification. RESULTS Skin samples prior to therapy showed a moderate to severe inflammatory infiltrate, mainly due to T lymphocytes with a helper/inducer (CD4) phenotype. Most of these cells also expressed ICAM-1 and VCAM-1. Blood vessels showed expression of E-selectin and VCAM-1, and keratinocytes were positive for ICAM-1 staining. The cell infiltrate was reduced after therapy, as well as the expression of cell adhesion molecules. However, we also noted the persistence of the T lymphocyte phenotype CD8(+), expressing the CD69 activation molecule, after the MTX treatment. CONCLUSIONS MTX downregulates the expression of some adhesion molecules, a phenomenon that may contribute to its anti-inflammatory therapeutic effect in psoriasis. The infiltrating T cells post-treatment have an activated cytotoxic phenotype, which may suggest a pathogenic role in the continuation and/or recurrence of psoriasis.
