The peroxisome proliferator-activated receptor-gamma...
Previous studies indicate that peroxisome proliferator-activated receptor-gamma (PPAR-g) agonists suppress autoimmune responses and renal inflammation in murine lupus. However, the mechanisms implicated in this process remain unclear. We tested the effect of the PPAR-g agonist pioglitazone in human lupus and control PBMCs with regards to gene regulation and various functional assays.We used microarrays to analyze the effect of Pioglitazone on peripheral blood cells (PBMCs) from healthy and lu...

The relationship between the gene expression profile...
Background: Although the use of TNF inhibitors has fundamentally changed the way rheumatoid arthritis (RA) is treated, not all patients respond well. It is desirable to facilitate the identification of responding and non-responding patients prior to treatment, not only to avoid unnecessary treatment but also for financial reasons. In this work we have investigated the transcriptional profile of synovial tissue sampled from RA patients before anti-TNF treatment with the aim to identify biomark...

The type of phagocytic receptor modulates gene expre...
The receptors engaged during phagocytic particle uptake determine the signaling events that occur during phagosome formation and maturation. However, pathogens generally have multiple ligands, making it difficult to dissect the roles of individual receptors in these processes. Here, we used latex beads coupled to single ligands, focusing on IgG, mannan, LPS and avidin, and monitored phagocytic uptake rates, phago-lysosomal fusion events, macrophage gene expression and the proteomic compositio...

Time course of bone marrow-derived macrophages simul...
The innate immune system is a two-edged sword; it is absolutely required for host defense against infection, but if left uncontrolled can trigger a plethora of inflammatory diseases. Here we used systems biology approaches to predict and validate a gene regulatory network involving a dynamic interplay between the transcription factors NF-κB, C/EBPδ, and ATF3 that controls inflammatory responses. We mathematically modeled transcriptional regulation of Il6 and Cebpd genes and experimentally v...

Time-dependent transcriptomic profiles of mouse hipp...
Mesial Temporal Lobe Epilepsy (MTLE) is a chronic disease characterized by recurrent unprovoked partial seizures. Current treatments lack long-term efficacy and typically act only to ameliorate the symptomology, rather than to modify the course of the disease. Chronic kainic acid (KA)-induced models of MTLE mimic prominent histopathological and electroencephalographic features of human MTLE, including hippocampal sclerosis, CA1 neuronal loss, astrogliosis, microgliosis, and electrographic hip...

To identify gene markers which differentiate between...
Aspirin-exacerbated respiratory disease (AERD) has association with severe asthma and aspirin can cause asthma to worsen, often in the form of a severe and sudden attack. The oral aspirin challenge (OAC) is the gold standard to confirm the diagnosis of AERD but it is time consuming and produces serious complications in some cases. Therefore more efficient and practical method is needed to predict AERD patients. The aim of the present study was to identify AERD-related gene expression in perip...

Transcriptional analysis of left-sided colitis, panc...
This study characterizes the inflammatory processes in left-sided colitis, pancolitis, and UC-associated dysplasia at the transcriptional level in colonics biopsies in order to identify potential biomarkers and transcripts of importance for the carcinogenic behaviour of chronic inflammation
