Atherosclerosis: Specific microRNAs promote inflammation
Date:3/22/2013

Atherosclerosis, an inflammatory reaction, is at the root of the most common forms of cardiovascular disease. Researchers at Ludwig-Maximilians-Universitaet (LMU) in Munich have now identified a microRNA that plays a prominent role in the process, and offers a promising target for new therapies.

Atherosclerosis otherwise known as hardening of the arteries is a prevalent cause of death in modern societies. The condition arises from the build-up of localized fatty deposits called plaques in the arteries. Macrophages, the phagocytic cells of the immune system, migrate to these sites, inducing chronic inflammation which exacerbates the accumulation of the atherosclerotic lesions. These can lead to obstruction of major vessels, causing heart attack and stroke. A team of medical researchers led by LMU's Professor Andreas Schober has now identified a microRNA (miRNA) that helps initiate the inflammatory process.

miRNAs are short segments of RNA derived from longer precursors transcribed from defined stretches of the genomic DNA. They act as versatile regulators of gene expression in cells, and also control the function of macrophages, in which patterns of gene activity must respond rapidly to changes in the extracellular environment. "However, the miRNAs that control the inflammation process during the various stages of atherosclerosis had not been identified up to now," says Schober.

In an earlier study, Schober and his team had shown that the microRNA miR-155 is a prominent member of the miRNA population in macrophages. The molecule prevents the synthesis of a protein that inhibits the inflammatory reaction, and thus promotes the progression of atherosclerosis. However, miR-155 does not serve as the initiator of inflammation. Schober and his colleagues have now looked at the patterns of microRNA expression in atherosclerotic lesions in the mouse, and noted that levels of a different miRNA, called miR-342-5p, increase in very early plaque
