Project description:Gene expression profiels in the human monocyte-derived dendritic cells (DCs) from 4 different donors (A, B, C, and D) were studied. Cells were left untreated (Group 4), activated with LPS alone (Group 1) or activated in the presence cmv IL-10 (Group 2) or human IL-10 (Group 3) for 12 hours before subjected to RNA extraction. Keywords: IL-10, LPS, dendritic cells

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:Interleukin-2 (IL-2) is one of the molecules produced by mouse dendritic cells (DCs) after stimulation by Toll like receptor (TLR) agonists. By analogy with the events following T-cell receptor (TCR) engagement leading to IL-2 production we have observed that DC stimulation with lipopolysaccharide (LPS) induces Src-family kinase and phospholipase C (PLC)γ2 activation, influx of extracellular Ca2+ and calcineurin-dependent nuclear NFAT translocation. We have also observed that the initiation of this pathway is independent of TLR4 engagement, and dependent exclusively on CD14. To determine the role of NFAT in LPS activated dendritic cells we have performed microarray analysis in conditions allowing or inhibiting NFAT activation. We show here that LPS-induced NFAT activation via CD14 is necessary to cause death of terminally differentiated DCs, an event that is essential for maintaining self-tolerance and preventing autoimmunity. Consequently, blocking this pathway in vivo causes prolonged DC survival and an increase in T cell priming capability. Gene expression analyses were performed using Affymetrix GeneChips in the following groups of murine bone marrow-derived dendritic cells: 1) CD14-deficient BMDCs stimulated with LPS; 2) wtBMDCs stimulated with LPS in presence of EGTA; 3) wtBMDCs stimulated with LPS. This experimental setting allowed us to select for effects due to Ca2+ fluxes and exclude the effects due to other causes, particularly the block of TRIF recruitment in CD14-deficient cells and the EGTA effects unrelated to Ca2+ chelation.

Project description:Nitidine Chloride(NC) were found to enhance IL-10 production in LPS-stimulated Bone-marrow dendritic cells(BMDCs ) ,while at the same time inhibit pro-inflammatory cytokines production, such as TNF- α and IL-6. BMDCs were treated with NC or vehicle following LPS stimulation to find out the influence of NC on BMDCs that regulate cytokines expression. This study indicated that NC regulate numerous gene expression, thus influence IL-10 and pro-inflammatory cytokines production in LPS-treated BMDCs.
