Project description:Lung myeloid dendritic cells isolated from emphysema but not healthy subjects induce Th1 and Th17 cells differentiation. The goal of this study is to identify the genes differentially expressed by lung myeloid dendritic cells from healthy or emphysema subjects. These genes may play crucial roles in directing Th1 and Th17 cells differentiation. Total mRNA was extracted from lung myeloid dendritic cells isolated from lungs of three healthy controls and three emphysema patients.

Project description:Analysis of lung CD11c+ antigen presenting cells (APCs) isolated from wildtype or Mir22-/- mice exposed to nanoparticulate carbon black (nCB) for one month. MiR-22 plays important roles in nCB induced experimental emphysema through regulating APC activation. Results provide insight into the biological role and target genes of miR-22. Smoking-related emphysema is a chronic inflammatory disease driven by T helper 17 (TH17) cells through molecular mechanisms that remain obscure. Here we have explored the role of microRNA-22 (miR-22) in emphysema. MiR-22 was upregulated in lung myeloid dendritic cells (mDCs) of smokers with emphysema and antigen-presenting cells (APCs) of mice exposed to smoke or nanoparticulate carbon black (nCB) through a mechanism involving NF-kappaB. MiR-22-deficient mice, but not wild-type, showed attenuated TH17 responses and failed to develop emphysema after exposure to either smoke or nCB. We further show that miR-22 controls APC activation and TH17 responses through activation of AP-1 transcription factor complexes and histone deacetylase (HDAC) 4. Thus, miR-22 is a critical regulator of both emphysema and TH17 responses. Lung APCs were isolated from PBS (reference groups) or nCB exposed wildtype or Mir22-/- mice, total four groups. There were three replicates in each group.

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.
