P030 SUCNR1 mediates inflammasome activation: Relevance in Ulcerative Colitis
2021
Abstract Background Ulcerative colitis (UC) is characterized by a diffuse, continuous, and chronic inflammation of mucosa and submucosa layers in the colon1. Inflammasome complex is involved in the intestinal homeostasis regulation, but its role in UC has not been established yet. We have recently reported that SUCNR1 mediates intestinal inflammation and fibrosis2. We aim to analyze the role of SUCNR1 in inflammasome activation and UC. Methods Intestinal resections from UC and non-IBD patients were obtained. HT29 cells were treated with succinate 1mM and an inflammasome activator cocktail (TNF-α 25ng/ml, IFN-γ 20 ng/ml and LPS 1µg/ml) for 24 hours and transfected with SUCNR1 siRNA. Chronic …
Increased airway inflammatory cells in endurance athletes: what do they mean?
2003
Background Inflammatory cells are increased in the airways of end urance athletes, but their role in causing exercise-induced respiratory symptoms and bronchoconstriction, or their possible long-term consequences, are uncertain. Aim To put the results of athlete studies in perspective, by analysing the pathogenesis of airway cell changes and their impact on respiratory function. Results Athletes of different endurance sports at rest showed increased airway neutrophils. Elite swimmers and skiers also showed large increases in airway eosinophils and lymphocytes, possibly related to chronic, exercise-related exposure to irritants or cold and dry air, respectively. Post-exercise studies reporte…

TYPE II DIABETES MELLITUS HAS NO MAJOR INFLUENCE ON PLATELET MICRO–RNA EXPRESSION: RESULTS FROM MICRO–ARRAY PROFILING IN A COHORT OF 60 PATIENTS
2013
Blood platelets represent pro–inflammatory mediators in the development of atherosclerosis. Diabetes mellitus as a major contributor to cardiovascular disease burden induces dysfunctional platelets. Platelets contain abundant miRNAs, which recently have been linked tightly to inflammation. While
Knock out der c-Jun N-terminalen Kinase 2 (JNK2) aggraviert die Entwicklung der chronischen DSS-Colitis unabhängig von der intestinalen Zytokin-Expre…
2008
Background The c-Jun N-terminal kinase 2 (JNK2) is involved in signal transduction of inflammatory bowel diseases (IBD) and regulates the expression of pro-inflammatory cytokines. For this reason, JNK2 is considered as novel target for IBD therapy. The aim of this study was 1.) to examine the function of JNK2 applying a low dose Dextran Sulfate Sodium (DSS) model of chronic experimental colitis in JNK2 knock out mice and 2.) to analyze the expression of JNK2 dependent cytokines. Material and Methods: For induction of a mild chronic colitis, female JNK2 knockout mice (JNK2 ko) and their wildtype controls (WT2) received three cycles of DSS treatment, each consisting of 1.0 % DSS for 5 days, f…

NF-κB in inflammatory bowel disease
2008
Apart from genetic and environmental factors, the mucosal immune system of the gut plays a central role in the pathogenesis of inflammatory bowel disease (IBD). In the healthy gut, the mucosal immune system ensures the balance between pro- and anti-inflammatory mediators and thereby allows an effective defence against luminal pathogens but at the same time prevents an overwhelming immune reaction directed against the huge amount of harmless luminal antigens (for example, components of food or nonpathological bacteria). In both entities of IBD (Crohn's disease and ulcerative colitis) this immunological balance is severely impaired and shifted towards the pro-inflammatory side. The chronic mu…
Protective potential of glucagon like peptide 2 (GLP-2) against the neurodegeneration
2019
Neurodegeneration consists in loss of neuron specific types, pattern and distribution, leading to progressive dysfunctions of the central nervous system. Neurodegenerative diseases include diverse pathological conditions, among which Alzheimer’s and Parkinson’s diseases are the most prevalent ones. Alzheimer’s disease is known as a growing dementia, characterized by progressive language, memory, and cognitive loss, while Parkinson’s disease is primarily characterized as a motor disorder. Senile plaques, caused by amyloid β peptide, hyperphosphorylated tau-based neurofibrillary tangles and synapse loss, are the principal pathological hallmarks of Alzheimer’s disease. Amyloid β oligomer forma…
