Biomarkers for inflammatory disease

06.12.2007
Gene-expression profiles might be used to identify prognostic biomarkers for Kawasaki disease, and help to unravel the underlying biology of the illness, research published this week in the online open access journal Genome Biology reveals. The new findings also support the idea that gene-expression profiles might be used to generate biomarkers for other systemic inflammatory illnesses.

Kawasaki disease, an acute, self-limited vasculitis, is the leading cause of acquired heart disease in children in developed countries, but its aetiologic and pathogenic mechanisms remain unclear.

A team of researchers led by David Relman, Stanford University, US, and Jane Burns, University of California at San Diego, US, characterized the gene expression patterns that occur in the blood cells of patients with this disease. They examined genome-wide transcript expression patterns in the blood of 77 children with Kawasaki disease.

The acute phase of the illness was accompanied by an increase in gene transcripts associated with innate immune mechanisms and proinflammatory responses, and a decrease in transcripts associated with natural killer cells and CD8+ lymphocytes, which help clear infected or abnormal cells from the body.

They showed that the transcript patterns during the acute phase of the disease varied dramatically with day of illness, and that differences in expression patterns between patients were associated with clinical parameters that physicians have used to manage and make predictions about the course of the disease. Patients who showed higher expression levels of specific transcripts (e.g., carcinoembryonic antigen-related cell adhesion molecule 1; CEACAM1) were less likely to respond to intravenous immunoglobulin, a highly effective but poorly understood treatment for preventing coronary artery aneurysms and reducing fever in Kawasaki disease.

This work contributes to our understanding of how the disease develops, how the treatment works, and how doctors might identify patients who are candidates for other therapies.

Im Focus: Fraunhofer IDMT demonstrates its method for acoustic quality inspection at »Sensor+Test 2019« in Nürnberg

From June 25th to 27th 2019, the Fraunhofer Institute for Digital Media Technology IDMT in Ilmenau (Germany) will be presenting a new solution for acoustic quality inspection allowing contact-free, non-destructive testing of manufactured parts and components. The method which has reached Technology Readiness Level 6 already, is currently being successfully tested in practical use together with a number of industrial partners.

Reducing machine downtime, manufacturing defects, and excessive scrap

Im Focus: Successfully Tested in Praxis: Bidirectional Sensor Technology Optimizes Laser Material Deposition

The quality of additively manufactured components depends not only on the manufacturing process, but also on the inline process control. The process control ensures a reliable coating process because it detects deviations from the target geometry immediately. At LASER World of PHOTONICS 2019, the Fraunhofer Institute for Laser Technology ILT will be demonstrating how well bi-directional sensor technology can already be used for Laser Material Deposition (LMD) in combination with commercial optics at booth A2.431.

Fraunhofer ILT has been developing optical sensor technology specifically for production measurement technology for around 10 years. In particular, its »bd-1«...

Im Focus: MPSD team discovers light-induced ferroelectricity in strontium titanate

Light can be used not only to measure materials’ properties, but also to change them. Especially interesting are those cases in which the function of a material can be modified, such as its ability to conduct electricity or to store information in its magnetic state. A team led by Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg used terahertz frequency light pulses to transform a non-ferroelectric material into a ferroelectric one.

Ferroelectricity is a state in which the constituent lattice “looks” in one specific direction, forming a macroscopic electrical polarisation. The ability to...

Im Focus: Determining the Earth’s gravity field more accurately than ever before

Researchers at TU Graz calculate the most accurate gravity field determination of the Earth using 1.16 billion satellite measurements. This yields valuable knowledge for climate research.

The Earth’s gravity fluctuates from place to place. Geodesists use this phenomenon to observe geodynamic and climatological processes. Using...
