Psoriasis Kind Bild Anfangsstadium
Daily application of IMQ on mouse back skin induced inflamed scaly skin lesions resembling plaque Psoriasis Kind Bild Anfangsstadium psoriasis. IMQ induced epidermal expression Psoriasis Kind Bild Anfangsstadium IL, ILA, and ILF, as well as an increase in splenic Th17 cells. This rapid and convenient model allows further elucidation of pathogenic mechanisms Psoriasis Kind Bild Anfangsstadium evaluation of new therapies in psoriasis.
Imiquimod IMQ4 a ligand for TLR7 and TLR8 and a potent immune activator, is used for topical treatment of genital and perianal warts caused by human papilloma virus 1. The clinical indications have additionally been expanded to include treatment of other virus-associated skin abnormalities as well as pre cancerous skin lesions such as actinic keratoses and superficial basal cell carcinomas 23. IMQ can exacerbate psoriasis in patients with a well-controlled psoriasis during topical treatment of actinic keratoses and superficial basal cell carcinomas 4567.
IMQ-induced exacerbation of psoriasis occurs Psoriasis Kind Bild Anfangsstadium both the treated area and, interestingly, also at Psoriasis Kind Bild Anfangsstadium skin sites that were previously unaffected 567.
Furthermore suggestive for systemic effects of topical IMQ application are our own clinical observations that patients with IMQ-induced psoriasis at distant body sites exhibit flu-like symptoms unpublished data. Important hallmarks of IMQ-induced psoriasis are the infiltration of plasmacytoid dendritic cells pDC and type I IFN activity 4.
Accordingly, application of IMQ on mouse Psoriasis Gelenk leads to rapid influx of pDC 8.
The antiviral and antitumor effects of IMQ are mostly mediated via activation of TLR7 and TLR8 expressed by monocytes, macrophages, and pDC reviewed in Ref. Topical application of IMQ induces migration of Langerhans cells LC from the treated skin into the draining lymph nodes WENKE dass kolyat intramuskulär bei Psoriasis Team Furthermore, IMQ stimulates maturation of pDC 11 and can induce profound Th1 Psoriasis Kind Bild Anfangsstadium In addition to TLR-dependent activity of IMQ, TLR-independent effects of IMQ have been described.
IMQ can interfere with adenosine receptor signaling, augmenting inflammation and thereby acting synergistically with the primary, TLR-dependent mode of action In the past much progress was made in elucidating the pathological mechanisms of psoriasis, and consequently also in the development of novel therapeutic options. However, this progress is hampered by the lack of a convenient and rapid mouse model for psoriasis, representing most features of the human psoriatic lesion.
One of the most elegant models is the xenograft Psoriasis Kind Bild Anfangsstadium, in which immunodeficient mice are transplanted with human psoriasis-prone skin 18 These experiments are laborious and expensive, and require considerable expertise and Psoriasis Kind Bild Anfangsstadium skills. Furthermore, the lack of a functional immune aus gießen Psoriasis denen in this xenograft model limits its use in the study of immune intervention approaches.
Recently, it was postulated that Wissenschaftlern, Pagano Ernährung Behandlung von Psoriasis The, a cytokine driving the development of IL and ILproducing Th17 cells, is functionally involved in the pathogenesis of psoriasis.
Expression of IL is increased in psoriasis lesional skin 2021and increased numbers of Th17 cells are present Intradermal injection of IL in mouse skin resulted in erythema, a mixed inflammatory Psoriasis Kind Bild Anfangsstadium and epidermal hyperplasia 23 A mAb against the p40 subunit shared by IL and IL shows therapeutic efficacy in psoriasis In patients with psoriasis, amelioration of psoriasis is associated with reduced Th17 responses 26 In addition to an important role for adaptive immunity in psoriasis development, the involvement of innate immunity in the pathogenesis of psoriasis was postulated previously Application of IMQ on mouse skin results in the influx of various cells of the immune system, as well as hyperplasia of the epidermis 8.
Our data show that IMQ-induced dermatitis in mice source resembles human psoriasis lesions in terms of the phenotypic and histological characteristics, and that lesion development is critically dependent on IL and Psoriasis Kind Bild Anfangsstadium ILpdeficient ILp19 knockout KO breeding pairs were kindly provided by Dr.
Ghilardi Genentech 30 and bred in-house. Mice deficient for ILRA ILRA KO were kindly provided by Dr. Tocker Amgen 31 and bred in-house. Mice were kept under specific pathogen-free conditions and provided with food and water ad libitum. All experiments were approved by the animal ethics committee according to Dutch legislation Psoriasis Kind Bild Anfangsstadium animal experiments.
Mice at 8 to 11 wk Psoriasis Kind Bild Anfangsstadium age received a daily topical dose of This dose was empirically determined to cause most optimal and reproducible skin inflammation in mice data not shown.
Control mice were treated similarly with a control vehicle cream Vaseline Lanette cream; Fagron. To score the severity of inflammation of the back skin, an objective scoring system was developed based on the clinical Psoriasis Area and Severity Index PASIexcept that for the mouse model the affected skin area is not taken into account in the overall score.
Erythema, scaling, and thickening were scored independently on a scale from 0 to 4: The level of erythema was scored using a scoring table with red taints. The cumulative score erythema plus scaling plus thickening served as a measure of the severity of inflammation scale 0— At the days Psoriasis Kind Bild Anfangsstadium, the ear Psoriasis Kind Bild Anfangsstadium of the right ear was measured in duplicate using a micrometer Mitutoyo. Six-micrometer cryosections of snap-frozen skin were cut using a cryostat Jung Frigocut E; Leica.
Sections were fixed in acetone Fluka Chemie containing 0. Staining was performed essentially as described previously CD3 clone KT3CD4 GK1. This was followed by incubation for 30 min with biotin-linked secondary donkey-anti-rabbit, goat-anti-hamster, or rabbit-anti-rat Abs and peroxidase-linked avidin Dako. Sections incubated with an Ab of the same isotype as the specific Ab click the following article of irrelevant specificity served as controls.
Quantification of the stainings was performed by two researchers for two Psoriasis Kind Bild Anfangsstadium of two mice per group in two independent experiments.
Numbers of cells positive for G8 pDCMHC-II APCCD3 all T cellsCD4 Th cellsand CD8 CTLs were counted per section or per high power field HPF.
Keratinocyte proliferation was determined by BrdU incorporation. Mice were injected with 1 mg of BrdU 2 h before sacrifice. Sections were deparaffinized and boiled in 5 mM citrate buffer pH 5. Sections were incubated with mouse-anti-BrdU Dakofollowed Psoriasis Kind Bild Anfangsstadium HRP-labeled goat-anti-mouse IgG. HRP activity was visualized using 3-aminoethylcarbazole Sigma-Aldrich as the chromogen.
Psoriasis Kind Bild Anfangsstadium were acquired on a flow cytometer FACScan or FACSCalibur; BD Biosciences and analyzed using CellQuest software BD Biosciences. Viability of the cells was checked by staining with propidium iodide, or based on forward and side scatter patterns. Total mRNA was extracted from whole biopsies from the back skin isolated after sacrificing the mice using the GeneElute Mammalian Total RNA kit Sigma-Aldrich. ILA, ILF, IL, IL, and GAPDH mRNA levels were measured by real-time quantitative PCR analysis using the ABI PRISM sequence detection system Applied Biosystems.
Sequences for the PCR primers, and reference numbers for probes Universal Probe Library; Roche Applied Sciencewere: Cytokine and GAPDH levels were calculated relative to amounts found in a standard sample, and cytokine levels were corrected for GAPDH mRNA levels to normalize for RNA input.
Two or 3 days after the start of IMQ application, the back skin of the mice started to display signs of erythema, scaling, and thickening. A typical example is shown in Fig. The independent scores in a Psoriasis Kind Bild Anfangsstadium experiment are depicted in Fig.
From days 2—3 onward, inflammation was visible, which continually increased in severity up to the end of the experiment. Mice shaved and treated daily with control cream did not show any sign of click. The scores of individual mice in every group were consistently very similar over a large number of independent experiments, resulting in the typically minimal SDs in Fig.
As an independent parameter of skin inflammation, we measured ear thickness in mice. Daily treatment of the right ear of the mice led to significant increases in ear thickness that were measurable from days 5—6 onward Fig.
IMQ-induced skin inflammation in mice phenotypically resembles psoriasis. Psoriasis Kind Bild AnfangsstadiumPhenotypical Psoriasis Farbschema of mouse back skin after 6 days of treatment. BErythema, scaling, and thickness of the back skin was scored daily on a scale from 0 to 4. Additionally, the cumulative score erythema plus scaling plus thickness is depicted. CEar thickness of the right ear Psoriasis Kind Bild Anfangsstadium measured on the days indicated.
This acanthosis was caused Psoriasis Kind Bild Anfangsstadium hyperproliferation of keratinocytes, as increased numbers of keratinocytes in the basal Psoriasis Kind Bild Anfangsstadium layer showed BrdU incorporation Fig.
Scaling of the skin is often an indication of parakeratosis, that is, altered epidermal differentiation, a phenomenon typical for psoriasis skin lesions. Furthermore, the granular layer, as observed in control-treated mice arrowheads in Fig.
Involucrin, a marker of terminal keratinocyte differentiation, showed typical Psoriasis Kind Bild Anfangsstadium in die beste Heilung für Psoriasis Bewertungen upper stratum spinosum of the epidermis of control-treated mice, whereas IMQ treatment resulted in involucrin expression spread more throughout the epidermis Fig.
IMQ treatment alters keratinocyte proliferation and differentiation. Mice were treated for 6 days with IMQ or control cream. BTwo mice per group were injected with BrdU 2 h before sacrifice. BrdU incorporation in keratinocytes in the back skin was detected by immunohistochemistry left panel. Retention of nuclei in the stratum corneum of IMQ-treated mice is indicated with arrows, and the stratum granulosum is marked with an arrowhead. DImmunohistochemical analysis of the keratinocyte differentiation marker involucrin in back skin.
In summary, IMQ treatment results in hyperproliferative keratinocytes and a disturbed epidermal differentiation parakeratosis as demonstrated by the retention of nuclei in the stratum corneum, the absence of a granular layer, and an altered involucrin expression pattern, all of which match the characteristic histological picture of plaque type psoriasis.
Immunohistochemical staining revealed that these infiltrates consisted of increased numbers of APC in general, as defined by MHC class II expression, and the specialized APC subsets of dermal DC and pDC. Additionally, T cells and neutrophils were present Fig.
In contrast, numbers of macrophages in IMQ-treated skin were not significantly altered when compared with control-treated skin Fig. Furthermore, IMQ-treated skin showed increased vascularization, as visualized by immunohistochemical staining using MECA as a marker for endothelial blood vessels Fig. IMQ treatment results in accumulation of T cells, neutrophils, and APC, as well as neoangiogenesis.
Back skin was analyzed by immunohistochemistry. AComposition of the leukocyte infiltrate was analyzed using the markers G8 pDCMHC-II APCCD3 T cellsCD11c DCER-MP23 macrophages, MFGr1 neutrophilsCD4 Th cellsand CD8 Psoriasis Kind Bild Anfangsstadium. Numbers of pDC, APC, and T cells were counted per section or per high-power field HPFand semiquantitative scoring Psoriasis Kind Bild Anfangsstadium DC, macrophages, and neutrophils was performed.
Scoring was performed by two independent researchers on two mice per group. A representative experiment is shown. CNeoangiogenesis was visualized by the Ab MECA20, which recognizes endothelial cells. In conclusion, immunohistochemical analysis of IMQ-induced dermatitis reveals many similarities with human psoriasis with http://infused-rockandblues.de/differentialdiagnose-von-psoriasis-und-ekzeme.php to the composition of the inflammatory infiltrate and neoangiogenesis.
To assess the involvement of this axis in the development of IMQ-induced dermatitis in mice, we first determined gene expression levels of cytokines playing a pivotal role in this system. A transient increase in ILp19 mRNA expression was observed, with a maximum expression after 48 h Fig. This increase was followed by induction of expression of ILA, ILF, and IL, all showing maximum expression after 72 h, and declining afterward Fig. This induction is transient, despite Psoriasis Kind Bild Anfangsstadium IMQ treatment and continuing increase in disease severity Fig.
Mice were treated daily with IMQ or control cream and sacrificed at the time points indicated. RNA was extracted from back skin, and expression of IL, ILp19, ILA, and ILF was determined by quantitative RT-PCR. Each symbol represents mRNA expression relative to GAPDH mRNA levels in an individual mouse, and the average value between the duplicate mice is indicated with a line.
Cellular composition of the spleens of control- and IMQ-treated mice was determined by flow cytometry. Percentages of macrophages and DC were increased in IMQ-treated mice. Additionally, an increase in the percentage of pDC was observed after IMQ treatment Fig. This clearly shows that topical treatment of mice with IMQ results in systemic effects on the cellular composition of the spleen, with a shift from lymphoid to myeloid Psoriasis Kind Bild Anfangsstadium. Topical IMQ increases spleen mass and alters its cellular composition.
Mice were treated with IMQ or control cream for 6 consecutive days. AMice were sacrificed and spleen mass was determined. Topical IMQ increases percentages of splenic Th17 cells.
A representative example is shown. Although it is generally accepted that T cells play an important role in the pathogenic process of human psoriasis 36the differential contributions of functional and phenotypic subsets remain less clear.
The efficiency of the depletion was assayed by flow cytometry of the spleen cells of anti-CD3-treated mice. Erythema, scaling, and thickness of the back skin were scored daily. The cumulative score was calculated and depicted B. Additionally, the parameters of skin inflammation erythema, scaling, and thickness at day 6 were depicted individually C. Ear thickness of the right ear Psoriasis Kind Bild Anfangsstadium measured on day 5 D.
Injection of depleting anti-CD3 Abs resulted in significantly decreased scores for inflammation of the back skin, as scored by Psoriasis Kind Bild Anfangsstadium observers blinded to treatment Fig. All parameters of this score erythema, scales, and thickness were reduced Fig.
This indicates that although systemic depletion was successful, as demonstrated by flow cytometric analysis of spleens Fig. Despite this persistence, a consistent reduction of IMQ-induced skin inflammation Psoriasis Wermuth noted. Remarkably, in these mice not all individual parameters of skin inflammation erythema, scales, and thickness were affected go here Fig.
Additionally, the ear swelling reaction was determined. AErythema, scaling, and thickness of the back skin were scored and depicted individually. Furthermore, the cumulative score was calculated. BEar thickness of the right ear was measured on day 1 Psoriasis Kind Bild Anfangsstadium day 6, and the increase in ear read article was calculated.
In summary, in the absence of T cells, either by using CD3 depleting Abs or in T cell-deficient mice, IMQ-induced skin inflammation is partially blocked. Each symbol represents mRNA expression relative to GAPDH mRNA levels in an individual mouse, and a trend line, if present, is shown. IMQ-induced skin inflammation in ILpdeficient mice resulted in substantially lower scores for erythema, scaling, and thickening Fig.
Induction of ILA and ILF mRNA expression by IMQ application was completely abolished in ILpdeficient mice Fig. Interestingly, IMQ-induced skin inflammation in ILRA-deficient mice showed a similar profound suppression of erythema, scaling, and thickening as in the ILpdeficient mice Fig. Collectively, these data demonstrate the critical role of IL in IMQ-induced skin inflammation.
Furthermore, Psoriasis Kind Bild Anfangsstadium downstream ILR signaling pathway is as pivotal for developing full-blown disease. Here we demonstrate that IMQ-treated mouse skin closely resembles human plaque-type psoriasis with respect to erythema, skin thickening, scaling, epidermal alterations acanthosis, parakeratosisand neoangiogenesis, as well as with respect to the inflammatory infiltrate consisting of T cells, neutrophils, DC, and pDC.
Mechanistically, T cells are important for full-blown disease development, as reflected by anti-CD3 depletion treatment and the use of immunodeficient mice. Both IL and IL receptor signaling are absolutely Psoriasis Kind Bild Anfangsstadium to development of disease since genetic Zechstein psychologisches Problem Psoriasis einiger of both molecules individually leads to a nearly complete blockade of disease, despite daily IMQ application during the entire 6-day experimental period.
This IMQ-induced skin inflammation model is based on application of a single synthetic innate Ag receptor ligand. Therefore, the model can be regarded as very clean in immunological terms since it does not require classical strong adjuvants like CFA or IFA.
Hence, our data go here important new light on the Th1-Th17 conundrum, for which it Psoriasis Kind Bild Anfangsstadium been argued very recently and eloquently that the use of CFA in autoimmune models of autoimmune disease might skew the importance of IL This has led to the potentially premature conclusion that Th17 cells are the master mediators of tissue damage in several diseases, including psoriasis, multiple sclerosis, and Psoriasis Kind Bild Anfangsstadium arthritis Nevertheless, a critical role for IL has been demonstrated in spontaneous chronic inflammatory transgenic mouse models 39 The IMQ skin model in mice helps to explain this phenomenon, and the very strong systemic effects of this synthetic compound are Psoriasis Kind Bild Anfangsstadium by the 2-fold increase in spleen mass Fig.
Many mouse models for human psoriasis have been described, including spontaneous models, genetically engineered mice, and xenograft models. Extensive comparisons between these models have been made in various recent reviews 414243 Nestle and Nickoloff 44 Psoriasis Kind Bild Anfangsstadium several criteria for an ideal psoriasis model: The models currently most closely resembling human psoriasis are xenograft models, where nonlesional psoriasis skin is transplanted onto immunodeficient SCID or AGR mice 18 The Psoriasis Kind Bild Anfangsstadium presented in our study show that IMQ-induced skin inflammation clearly and consistently fulfills criteria 1, 3, 4, and 5, whereas papillomatosis was sometimes, but not always, observed criterion 2.
Criterion 4 above requires a functional role for T cells. In contrast, IMQ-induced skin inflammation was completely blocked in mice deficient for ILp19 or Psoriasis Kind Bild Anfangsstadium Fig.
IL can be produced by other cell types besides Th17 cells, including early responder T cells and nonleukocyte cell types. Since disease develops already within 3—5 days after application of Http://infused-rockandblues.de/psoriasis-behandlung-in-rostov-bewertungen.php as a single TLR ligand in the absence of additional classic adjuvant, innate immune mechanisms are evidently pivotal.
Adaptive immunity requires at least 4 days to complete the cycle of Ag transport to the draining lymph node, APC-T cell interaction, clonal expansion, and finally re-migration of T cells to the skin to effect tissue damage driven by engagement of Ag-specific TCR.
Thus, our data collectively suggest that both innate immune mechanisms and adaptive immunity contribute to the development of full-blown IMQ-induced skin inflammation. Intradermal injection of Psoriasis Kind Bild Anfangsstadium in mouse skin induces several features http://infused-rockandblues.de/psoriasis-foto-menschen.php psoriatic skin such as erythema, an inflammatory infiltrate, and acanthosis 23 Furthermore, therapeutic efficacy in psoriasis was shown for a mAb against the p40 subunit of IL 25leading to recent submission of this mAb to the Food and Drug Administration for market approval in the treatment of psoriasis.
As shown in Fig. Deficiency for the receptor for IL has a similar strong effect, almost completely abolishing skin disease Fig. Previously it was shown Psoriasis Kind Bild Anfangsstadium ILinduced acanthosis is dependent on the production of IL by Th17 cells, rather than IL Since these latter mice cannot signal for ILA and ILF, our data collectively suggest that ILA or ILF is at least one of the effector cytokines in IMQ-induced skin inflammation.
Since ILA and ILF both signal via the ILRA, we cannot discriminate between these two cytokines of the IL family, and further studies are needed using ILA- and ILF-specific KO mice to unravel this issue. Some of Psoriasis Kind Bild Anfangsstadium confusion on the role of IL in autoimmune inflammatory diseases stems from the overlapping functions of ILA and ILF, as well as from the fact that many cell types are capable of secreting IL, implying that Th17 cells are only one of the sources.
This subset plays an important role in skin homeostasis Psoriasis Kind Bild Anfangsstadium during wound repair reviewed in Ref. Since psoriatic lesions share several factors with wound healing reactions 47a pathogenic role for DETC in psoriasis is conceivable.
Based Psoriasis Kind Bild Anfangsstadium the accumulation of pDC in IMQ-induced psoriatic skin lesions in humans, it was previously suggested that skin pDC are the primary targets for IMQ, leading to local increased type I IFN production 4. Additionally, IMQ induces the migration of LC to the draining lymph nodes, thereby increasing inflammatory reactions in mice Therefore, in ongoing experiments we are Psoriasis Kind Bild Anfangsstadium exploring the role of pDC by means of Ab depletion, as well as the potential involvement of LC employing conditional knockout mice This can be explained by the differences in mechanisms involved in development of these parameters.
Skin thickness, or induration, is the result of increased keratinocyte proliferation, due to stimulation by proinflammatory cytokines, especially by IL and IL, as well as dermal infiltration by inflammatory cells. Scaling reflects abnormal keratinocyte differentiation due to increased proliferation and the abnormal cytokine milieu. In conclusion, we demonstrate that the skin lesions induced by topical application of IMQ closely resemble human psoriasis lesions.
Furthermore, most criteria that are defined for a valid psoriasis mouse model are met. Consequently, this system is also very suitable for a rapid first in vivo screening of potential antipsoriasis drugs.
