(Submitter supplied) We sought to provide a comprehensive evaluation of the effects of TNF-α and IL-17 on the keratinocyte gene profile in order to identify genes that might be co-regulated by these cytokines. We then sought to determine how genes that were synergistically activated by both cytokines relate to the psoriasis transcriptome. Here, we identified 160 unique genes that were synergistically up-regulated by IL-17 and TNF-α and 188 unique genes where the two cytokines had at least an additive effect. more...

(Submitter supplied) To identify the gene expression in the peripheral edge of the lesional (PE) skin of psoriasis vulgaris. Methods: Full-thickness skin biopsies of PE skin and uninvolved skin were taken from psoriasis patients. Transcriptomic profiling was constructed by high-throughput next-generation sequencing (NGS) technology. Result: A total of 1,202 DEGs were identified. Of these, 653 (54%) were upregulated and 549 (46%) were downregulated. more...

(Submitter supplied) To increase our understanding of psoriasis, we utilized RNA-seq to assay the transcriptomes of skin samples from 3 Tnip1+/+ and 3 Tnip1-/- mice that were treated for two days with imiquimod (IMQ) and performed cross-species analyses with human transcriptome data derived from psoriasis patients and healthy subjects (GSE54456). Intriguingly, the vast majority of genes deregulated in Tnip1-/- mice correlated with their human counterparts, substantiating the interpretation that gene deregulation in Tnip1-/- mice reflects a psoriasis-specific pattern rather than being the consequence of an overall exaggerated inflammatory skin response. more...

(Submitter supplied) IL-6 inhibition has been unsuccessful in treating psoriasis, despite high levels of tissue and serum IL-6 in patients. Additionally, de novo psoriasis onset has been reported following IL-6 blockade in rheumatoid arthritis patients. To explore mechanisms underlying these clinical observations, we backcrossed an established psoriasiform mouse model (IL-17C+ mice) with IL-6 deficient mice (IL-17C+KO) and examined the cutaneous phenotype. more...

Analysis of non-lesional and lesional psoriatic skins for up to 43 days following treatment with various doses of brodalumab, a human IgG2 mAb that selectively binds and blocks signaling through IL-17RA. Results provide insight into the molecular effect of blocking IL-17 signaling in psoriatic skin.

(Submitter supplied) In psoriasis, inflammation and epidermal hyperplasia are thought to be controlled by T cell-derived cytokines. Evidence now suggests that Th17 and Th22 cells infiltrate psoriasis lesions and by secreting IL-17 and IL-22, respectively, may drive disease-specific gene or cell responses. While studies in model systems indicate that IL-22 has a dominant pathogenic role, there is evolving evidence that IL-17 contributes to features of psoriasis. more...

(Submitter supplied) Transcriptional profiling of Homo sapiens inflammatory skin diseases (whole skin biospies): Psoriasis (Pso), vs Atopic Dermatitis (AD) vs Lichen planus (Li), vs Contact Eczema (KE), vs Healthy control (KO) In recent years, different genes and proteins have been highlighted as potential biomarkers for psoriasis, one of the most common inflammatory skin diseases worldwide. However, most of these markers are not psoriasis-specific but also found in other inflammatory disorders. more...

(Submitter supplied) Atopic dermatitis and psoriasis are driven by alternate type 2 and type 17 immune responses, but some proteins might be critical to both diseases. We show that a deficiency of the TNF superfamily molecule TWEAK (TNFSF12) in mice results in defective maintenance of atopic dermatitis-specific Th2 and psoriasis-specific Th17 cells in the skin, and impaired expression of disease-characteristic chemokines and cytokines, such as CCL17 and TSLP in atopic dermatitis, and CCL20 and IL-19 in psoriasis. more...

(Submitter supplied) IL-36 cytokines have recently emerged as mediators of inflammation in autoimmune conditions including psoriasis vulgaris (PsV) and generalized pustular psoriasis (GPP). This study used RNA-seq to profile the transcriptome of primary epidermal keratinocytes (KCs) treated with IL-1B, IL-36A, IL-36B or IL-36G. We identified some early IL-1B-specific responses (8 hours post-treatment), but nearly all late IL-1B responses were replicated by IL-36 cytokines (24 hours post-treatment). more...
