Abstract
Psoriasis is a chronic immune-mediated inflammatory disease, affecting about 2 to 3% of the population worldwide. Nucleotide-binding and oligomerization domain 2-like receptor has been implicated in the pathogenesis of different inflammatory diseases. The current work aims to investigate the expression of nucleotide-binding and oligomerization domain 2-like receptor in psoriatic skin through an immunohistochemical study. This cross-sectional case-control study included 20 patients with chronic plaque psoriasis and 20 age- and sex-matched normal subjects as controls. Psoriasis severity was assessed through the use of Psoriasis Area Severity Index (PASI) score. Skin biopsies were taken under local anesthesia from cases and from matched sites of controls. Expression of nucleotide-binding and oligomerization domain 2 in epidermis of studied cases and controls showed positive epidermal expression of nucleotide-binding and oligomerization domain 2 in all cases (100%) versus 6 (30%) controls with a significant increase (χ2 = 21.54, P˂0.001). Moreover, dermal expression of nucleotide-binding and oligomerization domain 2 was higher in psoriatic skin lesion (95%) compared to controls (15%) with a significant difference (χ2 = 25.86, P˂0.001). We concluded that nucleotide-binding and oligomerization domain 2 may be implicated in psoriasis pathogenesis being higher in cases in comparison to controls.

Abstract
Recent studies have demonstrated that inhibition of p38α MAP kinase could effectively inhibit pro-inflammatory cytokines including TNF-α and interleukins. Thus, inhibition of this enzyme can prove greatly beneficial in the therapy of chronic inflammatory diseases. A new series of N-[3-(substituted-4H-1,2,4-triazol-4-yl)]-benzo[d]thiazol-2-amines (4a-n) were synthesized and subjected to in vitro evaluation for anti-inflammatory activity (BSA anti-denaturation assay) and p38α MAPK inhibition. Among the compounds selected for in vivo screening of anti-inflammatory activity (4b, 4c, 4f, 4g, 4j, 4m, and 4n), compound 4f was found to be the most active with an in vivo anti-inflammatory efficacy of 85.31% when compared to diclofenac sodium (83.68%). It was also found to have a low ulcerogenic risk and a protective effect on lipid peroxidation. The p38α MAP kinase inhibition of this compound (IC50 = 0.036 ± 0.12 μM) was also found to be superior to the standard SB203580 (IC50 = 0.043 ± 0.27 μM). Furthermore, the in silico binding mode of the compound on docking against p38α MAP kinase exemplified stronger interactions than those of SB203580.

Abstract
p38α mitogen activated protein kinase (MAPK) inhibitors provide a novel approach for the treatment of inflammatory disorders. A series of fifteen pyrazolyl urea derivatives (3a—o) were synthesized and evaluated for their p38α MAPK inhibition and antioxidant potential. Compounds 3a—e, 3g and 3h showed low micromolar range potency (IC50 values ranging from 0.037 ± 1.56 to 0.069 ± 0.07 µmol/L) compared to the standard inhibitor SB 203580 (IC50 = 0.043 ± 3.62 µmol/L) when evaluated for p38α MAPK inhibition by an immunosorbent-based assay. Antioxidant activity was measured by a 2,2′-diphenyl-1-picryl hydrazyl radical (DPPH) free radical scavenging method and one of the compounds, 3c, showed better percentage antioxidant activity (75.06%) compared to butylated hydroxy anisole (71.53%) at 1 mmol/L concentration. Compounds 3a—e, 3g and 3h showed promising in vivo anti-inflammatory activity (ranging from 62.25% to 80.93%) in comparison to diclofenac sodium (81.62%). The ulcerogenic liability and lipid peroxidation activity of these compounds were observed to be less in comparison to diclofenac sodium. These compounds also potently inhibited the lipopolysaccharide (LPS)-induced TNF-α release in mice (ID50 of 3a—c = 19.98, 11.32 and 9.67 mg/kg, respectively). Among the screened compounds, derivative 3c was found to be the most potent and its binding mode within the p38α MAPK is also reported.

Abstract
Increasing epidemiological studies in patients with psoriasis report the frequent occurrence of one or more associated disorders. Psoriasis is associated with multiple comorbidities including autoimmune disease, neurological disorders, cardiometabolic diseases and inflammatory-bowel disease. An integrated system biology approach is utilized to decipher the molecular alliance of psoriasis with its comorbidities. An unbiased integrative network medicine methodology is adopted for the investigation of diseasome, biological process and pathways of five most common psoriasis associated comorbidities. A significant overlap was observed between genes acting in similar direction in psoriasis and its comorbidities proving the mandatory occurrence of either one of its comorbidities. The biological processes involved in inflammatory response and cell signaling formed a common basis between psoriasis and its associated comorbidities. The pathway analysis revealed the presence of few common pathways such as angiogenesis and few uncommon pathways which includes CCKR signaling map and gonadotrophin-realising hormone receptor pathway overlapping in all the comorbidities. The work shed light on few common genes and pathways that were previously overlooked. These fruitful targets may serve as a starting point for diagnosis and/or treatment of psoriasis comorbidities. The current research provides an evidence for the existence of shared component hypothesis between psoriasis and its comorbidities.

Abstract
Psoriasis is a chronic disease of the skin characterized by hyper proliferation and inflammation of the epidermis and dermal components of the skin. T-cell-dependent inflammatory process in skin governs the pathogenesis of psoriasis. An in-silico search strategy was utilized to identify psoriatic therapeutic drug targets. The gene expression profiling of psoriatic skin identified a total of 427 differentially expressed genes (DEGs). Gene ontology investigation of DEGs identified genes involved in calcium binding, apoptosis, keratinisation, lipid transportation and homeostasis apart from immune mediated processes. The protein interaction networks identified proteins involved in various signaling mechanisms with high degree of interconnections. The gene modules derived from the main network were enriched with rich kinome. These sub-networks were dominated by the presence of non-receptor kinase family members which are major signal transmitters in immune response. The computational approach has aided in the identification of non-receptor kinases as potential targets for psoriasis drug development.

Abstract
Psoriasis is a common chronic skin disease characterized by recurrent erythromatous skin plaques that exhibit epidermal hyperplasia, variable inflammatory cell infiltrate, and abnormalities of the dermal vascularization. The involvement of angiogenic growth factors such as vascular endothelial growth factor (VEGF), matrix metalloproteinases (MMPs) and inflammatory cytokines such as IFNγ, IL-1, IL-2, TNFα, TGFα and β, IL-6, IL-8, amphiregulin and monocyte chemoattractant protein 1 (MCP-1) have been known to play pathogenic roles in traumatic psoriatic skin. However, anti-angiogenic and anti-inflammatory cytokines regimens might favorably affect the psoriasis disease process. Tranilast is an anti-allergic drug now emerging as anti-angiogenesis and anti-inflammatory effects. In vitro and in vivo experiments have also been strongly showed that tranilast would treat skin psoriasis by inhibition of involving factors. Herein, we hypothesize that local administration of tranilast may be potentially clinically useful in psoriasis.

Abstract
Psoriasis is a common chronic inflammatory disease of the skin and joints. Autoantibodies have been reported in psoriasis patients. Objective of the study was to see the prevalence of various autoantibodies in patients of psoriasis and its correlation with gender, age, and type. Anti-nuclear antibody and antibody to double-stranded deoxyribonucleic acid were studied by indirect enzyme linked immunosorbent assay, rheumatoid factor was done by latex agglutination, whereas anti-thyroid microsomal antibody (anti-TMA) was by gelatin agglutination method. About 28.8% of psoriasis cases were positive for atl east one autoantibody. Age of onset (P=0.033) and types of psoriasis (P=0.037) had significant association with gender. Anti-double-stranded deoxyribonucleic acid (P=0.029) and anti-thyroid microsomal antibody (P=0.002) had significant association with types of psoriasis. Gender wise distribution of psoriasis in age group had significant (P=0.03) association with anti-TMA. This study concludes that the autoantibodies are found to be present in psoriasis patients or latent autoimmune diseases develop in psoriasis patients without any clinical symptoms.

Abstract
Infiltration of T cells is a key step in the pathogenesis of the inflammatory skin diseases atopic dermatitis, allergic contact dermatitis and psoriasis. Understanding the mechanisms of T cell recruitment to the skin is therefore of fundamental importance for the discovery and application of novel therapies for these conditions. Studies of both clinical samples and experimental models of skin inflammation have implicated specific adhesion molecules and chemokines in lymphocyte recruitment. In particular, recent studies using advanced in vivo imaging techniques have greatly increased our understanding of the kinetics and molecular basis of this process. In this review, we summarise the current understanding of the cellular immunology of antigen-driven dermal inflammation and the roles of adhesion molecules and chemokines. We focus on results obtained using intravital microscopy to examine the dermal microvasculature and interstitium to determine the mechanisms of T cell recruitment and migration in experimental models of T-cell-mediated skin inflammation.
