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)

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:Complete identification of the bone marrow niche remains one of the most progressing fields. Attempts to identify soluble factors involved in stem cell renewal have been less successful. We have previously shown that endothelial cells (EC) can induce the long-term proliferation of hematopoietic progenitor cells (HPC), especially when they had been subjected to an inflammatory stimulus like interleukins (IL) 1. To identify yet unknown growth factors, we compared the expression profile of IL-1 stimulated and non-stimulated endothelial cells. Human endothelial cells were subjected to IL-1 for 4, 8, and 16 hours. Isolated mRNA was analyzed by oligonucleotide microarray chips covering over 46,000 human genes.

Project description:The human dataset includes the gene expression profile of CD4+ T cells isolated from blood of healthy controls and plated on TCP in RPMI-1640 containing 10% FCS, Penicillin-Streptomycin (50,000 units-50 mg) and L-glutamine (2 mM). Cells were stimulated for 4 days with 20 ng/ml of IL-1beta, 100 IU/ml of IL-2, 20 ng/ml of IL-6, 20 ng/ml IL-23 plus anti-CD2/3/28 beads at a ratio of 1 bead per 10 cells. RNA samples were isolated using the RNeasy Mini Kit (Qiagen) with on-column DNA digestion. The transcriptional profile was evaluated in three different donors using the HT12v4.1 BeadChip arrays from Illumina.
