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:New alkyl-phospholipids (APLs) that are structurally derived from the platelet-activating factor are promising candidates for anticancer treatment. After the incorporation into cell membranes, APLs are able to interfere with a wide variety of key enzymes implicated in cell growth, motility, invasion and apoptosis. Recently, using Agilent cDNA microarray technology, we could demonstrate that the glycosidated APL Ino-C2-PAF inhibited the expression of several genes associated with immune response and inflammation in immortalized keratinocytes HaCaT. Here, we analyzed the impact of Ino-C2-PAF on the gene expression profile of HaCaT cells treated with several pro-inflammatory cytokines (IL-1M-NM-1, IL-17, IL-22, TNF-M-NM-1 and oncostatin-M). The influence of Ino-C2-PAF on the transcriptional profile of immortalized keratinocytes (HaCaT) was analyzed treating HaCaT cells with 5 M-BM-5M Ino-C2-PAF in the presence of a mixture of pro-inflammatory cytokines (IL-1M-NM-1, IL-17, IL-22, TNF-M-NM-1 and oncostatin-M) for 24 h. Control cells were left untreated. Three independent experiments were performed for each condition, except for control cells where only two experiments were performed. Control cells were mainly necessary to demonstrate the efficiency of this in vitro inflammation model for keratinocytes.
