Project description:

Myocardial infarction and stroke are the main causes of morbidity and mortality worldwide, primarily caused by atherosclerosis, a chronic inflammatory disease of the arterial vessel wall. Macrophages (phagocytic cells) take over a key role in the development of atherosclerosis. Macrophages are recruited by inflammatory mediators of the immune system. However, as demonstrated in this publication, these mediators might have protective effects on macrophage programming depending on their respective source and origin. As now shown, distinct inflammatory mediators, when released from smooth muscle cells, can maintain a functionally protective phenotype of macrophages and reduce chronic inflammation in atherosclerosis. New anti-inflammatory approaches should therefore take into account protective effects of otherwise pro-inflammatory mediators within distinct compartments.

Submitting the Paper of the Month:

Else Kröner-Fresenius-Stiftung is using the series “Paper of the Month” to report in an exemplary and hot-off-the-press style on the outstanding work being done by the scientists it supports. We regularly present publications which have recently appeared in especially renowned journals, have emerged from foundation funding and been given appropriate acknowledgment. This is done in the respective categories “Original Paper” and “Review”. In the case of each of these publications, the first author and/or senior author are being funded by the foundation.

We invite all project managers, fellowship recipients and members of graduate study programs to send their work in accordance with the stated criteria as proposal for Paper of the Month to Ms. Anne Asschenfeldt (
