Assessments of diseases are usually performed by a combination of clinical symptoms, signs and objective measurements. Biochemical markers of inflammation are important in evaluation of treatment of acute and chronic diseases. In this thesis we have focused on two inflammatory diseases: acute radiation proctitis and rheumatoid arthritis. We examined established and new biomarkers, with focus on...

BACKGROUND Relatively few laboratory markers have been evaluated for the detection or monitoring of intestinal inflammation in canine chronic enteropathies, including inflammatory bowel disease (IBD). Previous research found that the intestinal mucosal levels of S100A12 and myeloperoxidase (MPO), as biomarkers of gut inflammation, were elevated in human patients with IBD. To date, the S100A12 a...

The receptor for advanced glycation end products (RAGE), a transmembrane receptor in the immunoglobulin superfamily, is involved in several inflammatory processes. RAGE induces cellular signaling pathways upon binding with various ligands, such as advanced glycation end products (AGEs), β-amyloids, and S100 proteins. The solution structure of S100A12 and the V ligand-binding region of RAGE have...

Background S100A12 is a member of the damage-associated molecular pattern molecules (DAMP) and expressed by activated granulocytes exhibiting its proinflammatory capacity by binding to the Receptor for Advanced Glycation Endproducts (RAGE). The aim of this study was to evaluate S100A12 in MWS patients before and during therapy with Anakinra (IL1Ra) and Canakinumab (a fully human monoclonal anti...

BACKGROUND AND PURPOSE Atherosclerosis is a progressive chronic disease, in which inflammation plays a key role. The calcium-binding proteins calgranulins including S100A8, S100A9, and S100A12 are involved in many cellular activities and pathological processes including inflammation. We therefore hypothesized that calgranulins may be markers of plaque instability in patients with carotid athero...

INTRODUCTION Acute lung injury (ALI) after cardiac surgery is associated with a high postoperative morbidity and mortality, but few predictors are known for the occurrence of the complication. This study evaluated whether elevated plasma levels of soluble receptor for advanced glycation end products (sRAGE) and S100A12 reflected impaired lung function in infants and young children after cardiac...

INTRODUCTION The receptor for advanced glycation end products (RAGE) is a member of the immunoglobulin superfamily of cell surface receptor molecules. High concentrations of three of its putative proinflammatory ligands, S100A8/A9 complex (calprotectin), S100A8, and S100A12, are found in rheumatoid arthritis (RA) serum and synovial fluid. In contrast, soluble RAGE (sRAGE) may prevent proinflamm...

Introduction The receptor for advanced glycation end products (RAGE) is a multi-ligand receptor expressed on various cells which interacts with a diverse class of ligands, e.g. ‘danger signals’ such as neutrophil-derived S100A12. RAGE has been implicated in the pathogenicity of various inflammatory diseases. However, the exact role of RAGE has not been sufficiently defined. Our recent data on S...

The study aimed to investigate whether S100A9 gene silencing mediating the IL-17 pathway affected the release of pro-inflammatory cytokines in acute pancreatitis (AP). Kunming mice were assigned to the normal, AP, AP + negative control (NC), AP + shRNA, AP + IgG and AP + anti IL-17 groups. ELISA was applied to measure expressions of AMY, LDH, CRP, TNF-α, IL-6 and IL-8. The cells were distribute...
