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: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Im Focus: Stem cell divisions in the adult brain seen for the first time

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...

Im Focus: Interference as a new method for cooling quantum devices

Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters

Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
