(Submitter supplied) Normal human epidermal keratinocytes (NHEK) from neonatal foreskin were cultured in serum-free EpiLife medium with human KC growth supplement (0.2% bovine pituitary extract (v/v), 5ug bovine insulin, 5ug/ml bovine transferrin, 0.5ng/ml human EGF, and 0.18 ug/ml hydrocortisone) from Cascade Biologics. Cultures were treated with recombinant cytokines from R&D Systems. J Immunol. 2007 Feb 15;178(4):2229-40. more...

(Submitter supplied) In the early stages of wound healing, keratinocytes become “activated” and release inflammatory molecules such as interleukin-1 and interleukin-8 that are linked to innate immune responses and neutrophil recruitment. It is unclear, however, whether keratinocytes release molecules linked to adaptive immune responses, e.g. CCL20, in their early state of activation without signals from infiltrating T cells. more...

Analysis of trypsin-disassociated keratinocytes (KCs) isolated from normal skin as a model for epidermal injury. These sorted keratinocytes (KC sorted) were compared to KCs isolated by LCM (KC LCM) and long-term cultured KCs (KC in vitro). Results provide insight into the KC injury response.

(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) IL-20 cytokines are involved in the establishment of psoriasis, a common chronic skin inflammation epidemiologically associated with metabolic syndrome, but molecular mechanisms underlying their over-expression remain to be elucidated. We find that keratinocytes (KCs) expressed IL-20 and lymphocytes expressed IL-22 cytokines up-regulation occurs at post-transcriptional level with stabilization of their RNA messengers. more...

(Submitter supplied) Background: IL-17 is the defining cytokine of the Th17, Tc17, and γδ T cell populations that plays a critical role in mediating inflammation and autoimmunity. Psoriasis vulgaris is an inflammatory skin disease mediated by Th1 and Th17 cytokines with relevant contributions of IFN-γ, TNF-α, and IL-17. Despite the pivotal role IL-17 plays in psoriasis, and in contrast to the other key mediators involved in the psoriasis cytokine cascade that are capable of inducing broad effects on keratinocytes, IL-17 was demonstrated to regulate the expression of a limited number of genes in monolayer keratinocytes cultured in vitro. more...

(Submitter supplied) In this study we tested interactions between IL-36 and IL-17A in human keratinocytes. 24 hours of IL-36 stimulation in keratinocytes promoted IL-36, IL-17C, and characteristic psoriasis-related molecule expressions in normal human epidermal keratinocytes in dose-dependent manners as measured by mRNA and protein quantification.

(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...

(Submitter supplied) Psoriasis is a common inflammatory skin disease characterized by aberrant inflammation and epidermal hyperplasia. Molecular mechanisms that regulate psoriasis-like skin inflammation remain to be fully understood. Here we show that the expression of Ovol1 transcription factor is upregulated in psoriatic skin, and its deletion results in aggravated psoriasis-like skin symptoms following stimulation with imiquimod (IMQ). more...

(Submitter supplied) Skin constitutes the outer permeability barrier that protects the body from dehydration and a myriad of external assaults. Epidermal keratinocytes act as the first line of innate immune defense, and barrier defects underlie common inflammatory skin diseases. However, the molecular mechanisms that maintain barrier integrity when skin is under challenge to regulate the interplay between epidermal and immune cells are not fully understood. more...
