Project description:Wound healing within the oral mucosa results in minimal scar formation compared to wounds within the skin. We have recently demonstrated distinct differences in the ageing profiles of cells (oral mucosal and patient-matched skin fibroblasts) isolated from these tissues. We hypothesize that the increased replicative potential of oral mucosal fibroblasts may confer upon them preferential wound healing capacities. Passage-matched early cultures of oral mucosal fibroblasts and skin fibroblasts demonstrated distinct gene expression profiles with a number of genes linked to wound healing/tissue repair. We analyzed the gene expression profiles of oral mucosal and patient-matched skin fibroblasts for multiple patients both prior to (0h) and (6h) following a wounding stimulus.

Differences in the gene expression profiles of oral mucosal and patient-matched skin fibroblasts were anlazyed for multiple patients both prior to (0h) and (6h) following a wounding stimulus. Serum starvation and subsequent stimulation provides a model for wounding and RNA extracted at 0h and 6h following this stimulus was hybridized to Affymetrix microarrays for analysis. We sought to compare the expression profiles both between oral and normal fibroblasts, in both serum depleted and stimulated conditions and also compare differences between patients.

Project description:When compared to skin, oral mucosal wounds heal rapidly and with reduced scar formation. This study used an Affymetrix microarray platform to compare the transcriptomes of oral mucosa and skin wounds in order to identify critical differences in the healing response at these two sites. Using microarrays, we explored the differences in gene expression in skin and oral mucosal wound healing in a murine model of paired equivalent-sized wounds. Samples were examined from day 0 to day 10 and spanned all stages of the wound healing process. Unwounded matched tissue was used as a control. Tissue samples collected at each post-wounding time point, as well as control samples, were represented by 3 biological replicates.

Project description: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. We performed an unsupervised cluster analysis of gene expression profiles in 150 psoriasis patients and other inflammatory skin diseases (atopic dermatitis, lichen planus, contact eczema, and healthy controls). We identified a cluster of IL-17/TNFα-associated genes specifically expressed in psoriasis, among which IL-36γ was the most outstanding marker. In subsequent immunohistological analyses IL-36γ was confirmed to be expressed in psoriasis lesions only. IL-36γ peripheral blood serum levels were found to be closely associated with disease activity, and they decreased after anti-TNFα-treatment. Furthermore, IL-36γ immunohistochemistry was found to be a helpful marker in the histological differential diagnosis between psoriasis and eczema in diagnostically challenging cases. These features highlight IL-36γ as a valuable biomarker in psoriasis patients, both for diagnostic purposes and measurement of disease activity during the clinical course. Furthermore, IL-36γ might also provide a future drug target, due to its potential amplifier role in TNFα- and IL-17 pathways in psoriatic skin inflammation.

Project description:Rapid and scarless wound repair is a hallmark of the oral mucosa, yet the cellular and molecular mechanisms that enable this regeneration remain unclear. By comparing populations of oral mucosal fibroblasts (OMFs) and facial skin fibroblasts (FSFs), we have identified the mechanisms that facilitate regeneration over fibrosis. We found that OMFs utilize Growth arrest specific-6 (GAS6)-AXL signaling to suppress fibrosis-related mechanosignaling via Focal adhesion kinase (FAK). Inhibition and knockdown of AXL in the oral mucosa resulted in fibrotic wounds and increased activation of FAK. At the same time, stimulation of AXL in the facial skin yielded wounds that heal regeneratively. Rare human oral scars that resulted from repetitive injury showed decreased expression of GAS6/AXL and increased FAK. Activating AXL in repetitively injured mouse oral tissue resulted in better wound healing outcomes and reduced scarring. Together, our work demonstrates that AXL signaling is necessary for regenerative wound healing in the oral mucosa and sufficient to limit facial skin fibrosis.

Project description:Analysis of ex vivo isolated lymphatic endothelial cells from the dermis of patients to define type 2 diabetes-induced changes. Results preveal aberrant dermal lymphangiogenesis and provide insight into its role in the pathogenesis of persistent skin inflammation in type 2 diabetes. The ex vivo dLEC transcriptome reveals a dramatic influence of the T2D environment on multiple molecular and cellular processes, mirroring the phenotypic changes seen in T2D affected skin. The positively and negatively correlated dLEC transcripts directly cohere to prolonged inflammatory periods and reduced infectious resistance of patients´ skin. Further, lymphatic vessels might be involved in tissue remodeling processes during T2D induced skin alterations associated with impaired wound healing and altered dermal architecture. Hence, dermal lymphatic vessels might be directly associated with T2D disease promotion. Global gene expression profile of normal dermal lymphatic endothelial cells (ndLECs) compared to dermal lymphatic endothelial cells derived from type 2 diabetic patients (dLECs).Quadruplicate biological samples were analyzed from human lymphatic endothelial cells (4 x diabetic; 4 x non-diabetic). subsets: 1 disease state set (dLECs), 1 control set (ndLECs)
