Influence of the internal clock on atherosclerosis

Work by Carla Winter, Oliver Söhnlein and colleagues may improve therapeutic approach


During atherosclerotic inflammation, characteristic lipid deposits develop on the inner vascular walls of large arteries, which in turn triggers the continuous recruitment of leukocytes to these sites.

The team of Oliver Söhnlein has now shown in mouse models that this recruitment is subject to circadian rhythms: migration to the arterial system on the one hand and to the microcirculation in small veins on the other hand are 12 hours phase shifted.

Combining these rhythmic shifts with insights into the capability of the chemokine CCL2 to inhibit arterial leukocyte migration specifically would potentially improve therapeutic approaches.

Collaborative effort

The publication greatly benefitted from close collaborations between three groups within SFB 914. The work of Carla and colleagues of project B08 (PI Oliver Söhnlein) was complemented by input from project B09 (PI Christoph Scheiermann) and project B01 (PI Markus Sperandio).
